This article introduces the technology,explains some new terms and showshow the HMC fits into the POWER5*system. I’ll start by explaining what theHMC is, when you need to have oneand how it connects to the POWER5system. Next, I’ll review some of thebenefits it brings to the platform andintroduce some changes in PTF or “fixmanagement” that must be understood.

What is the HMC?When referring to the HMC, IBM uses

the term “appliance” to distinguish itfrom any other Intel* technology-based server. It comes with a closedLinux* technology-based operating system packaged as the HMC firmware.The operating system is closed by asecure interface that helps prevent tampering and also preventsunauthorized software from beinginstalled. These restrictions help ensurethe HMC’s stability and the criticalservices it provides.

Not every POWER5 server requires an

HMC, but several technologies dorequire one. The HMC is required for thefollowing:

• Systems with LPARs• Systems with Capacity Upgrade on

Demand (CUoD)• Systems with redundant service

processors (currently this is onlyimplemented on the high-end systems—i595, p590 and p595)

• Systems with bulk power assemblies(only on high-end systems)

M any questions have

been circulating in

the iSeries*

community about the

new Hardware Management

Console (HMC) since its

introduction on the IBM* ^ i5

system. Is it required? Why would you want one? What benefits will it provide?

To eliminate the HMC as a single point of failure, a second HMC can be connected. For a single server, these could be direct cables. For more than one

server, a switch or hub is required. Since each HMC can manage multiple servers, this example could expand to the current maximum of 64 servers.

The HMC offloads some of the advanced technology thatwas integrated into OS/400*. Because the HMC is an externalappliance capable of managing server resources, a primarypartition is no longer needed for LPAR, which frees up serverresources. The HMC communicates with the server firmwarelayers of the POWER5 servers, allowing a single HMC to concurrently manage up to 48 servers and up to 254partitions. The servers can be any mix of ^ i5 or^ p5 systems.

Other HMC features include extensive logging capabilities,problem management, customized user profiles to controlsystem access, dynamic LPAR management and more. It canbe a service focal point collecting event information and errorreporting for multiple servers and multiple operating systems.It can report service events to IBM (call-home function) forany or all attached servers. It also has the capability to be thesystem console for any partition it manages (i.e., i5/OS*, Linuxand AIX*). It provides an access capability for remote users toconnect to the HMC using any 5250 emulator. From here, theuser can choose which server and then which i5/OS consolesession to join. When the HMC starts the console session,controls are selected to allow or not allow a remote

connection. If it’s allowed, this means a remote 5250 user canhave full i5/OS system-console capabilities.

The HMC provides additional remote capabilities; secureshell (SSH) for command-line access and Web-based SystemManagement (WebSM) for remote GUI access. WebSM is theGUI interface used by HMC. The WebSM client is includedwith the HMC firmware and can be downloaded to anyworkstation. Remote users can perform almost all of the samefunctions as the HMC with a few exceptions such as some ofthe security-management functions. V4R5, the most currentfirmware level of the HMC, was released in May and enhancedto allow access to Advanced System Management Interface(ASMI) from a WebSM client. ASMI is a browser-based userinterface that’s used to manage the Flexible Service Processor(FSP), which is the firmware layer that provides diagnostics,initialization, configuration, and runtime error detection andcorrection. It also retains a Flash copy of the LPARconfiguration and POWER Hypervisor* firmware that’s loadedduring initialization.

If your shop isn’t using any of the aforementionedtechnologies that require the HMC, you may not need anHMC on your ^ i5 system. In that case, your new

system will look and feel exactly as the iSeries and AS/400*systems have in the past, except of course it will have theextended POWER5 processing capacity. Your current systems-management processes (e.g., saves and PTF maintenance) willremain unchanged. Also note that the HMC is independentfrom the operating systems it manages, and iSeries Navigatorwill continue to be the systems-management tool of choicefor i5/OS.

How the HMC Connects to the Server Firmware The HMC uses TCP/IP to communicate with the FSP over anEthernet LAN. The session data is encrypted using SSL. Thisconnection can be a single Ethernet cable directly from ETH0(port 0 on the HMC) to HMC1 (first port on the FSP). Toconnect an HMC to more than a single managed server, use aswitch or hub between the HMC and the servers to bemanaged.

You should configure the HMC to be a dynamic hostconfiguration protocol (DHCP) server, and you must do sowhen connecting to a high-end server (e.g., i595, p590 orp595). By default, the FSP uses a DHCP client to request an IP

address. If no DHCP server is available, the FSP has twodefault IP addresses: 192.168.2.147 on HMC1 port and192.168.3.147 on HMC2 port. It’s recommended that youalways power on and configure the HMC first, typically as aDHCP server on a private network, then power on the^ i5 system. This helps ensure that the HMC DHCPserver is available to assign an IP address for the FSP. Usingthis method, the HMC will also “discover” the servers on itsprivate service network. Another option is to use static IPaddresses. This option requires several additional steps.

Whether you choose to use DHCP or a static IP address,configure the HMC first. To begin, sign on to the HMC withthe administrative user ID hscroot. The initial password isabc123. The Guided Setup Wizard starts automatically the firsttime you sign on and steps you through all of the basicconfiguration requirements. This includes changing the defaultpasswords, setting up the network options and setting up forhardware call home. The wizard locates each Ethernet card onthe HMC and prompts for configuration options. I stronglyrecommend that the first interface be configured as a privateservice network using DHCP to manage your servers. Thisprivate DHCP network is fully separate and will not interferewith any DHCP servers on your open network.

Once you’ve configured the HMC to be a DHCP server, youcan power on the ^ i5 system. The FSP will boot up atpower-on, and the DHCP client on the FSP will request an IPaddress. The HMC assigns this address since it’s the only DHCPserver on this private service network. (Note: At this time, theHMC can only be a DHCP server on one Ethernet port.)

If you elect to use static IP addresses, you must configurethe IP addresses on both the HMC and the FSP, and manually

add the server to the HMC. (Note: To configure the IPaddresses on the FSP, you access the FSP feature called ASMI.From ASMI, you can configure one or both Ethernet ports,and then reboot the FSP to activate the assigned IP addresses.Once the HMC connects to the server, you can launch anASMI session directly from the HMC, should you need toaccess these or other features.) To access ASMI before theHMC is connected:

1. After the ^ i5 system is powered on, set the staticIP address you selected in the FSP. Physically cable aworkstation to one of the FSP ports and set the IP address ofthe workstation to the 192.168.x.x subnet. Using any commonbrowser, connect to the FSP using one of the default IPaddresses as the URL: HTTPS://192.168.2.147 orHTTPS://192.168.3.147, depending on which FSP port you areaccessing. Sign on using the administrative id admin and theinitial password admin.

2. On the HMC, select the Server Management tab, then theAdd Server option using the IP address you just assigned fromASMI. You can use a host name if you’ve associated a hostname with this IP address and registered it with a DNS serverthat the HMC can access.

HMC History Lesson and Firmware Overview

A lthough the Hardware Management Console (HMC) is new to

iSeries* customers, this technology has been in use for a while

with zSeries* systems. The HMC was introduced for pSeries*

systems when POWER4* was released several years ago as it was

necessary to enable LPAR support and Capacity on Demand (CoD).

Another version of HMC is used by IBM* storage products; however,

at this time zSeries, storage and POWER4 HMCs aren’t compatible

with POWER5* HMCs. Some POWER4 HMCs can be upgraded to

POWER5 firmware. However, they would no longer be usable with

POWER4 systems once the firmware is upgraded.

Changes in the underlying architecture of the POWER5* server

have resulted in the introduction of HMC on ^ i5 systems.

Prior to i5/OS*, OS/400* included microcode layers referred to as

License Internal Code (LIC), the Technology Independent Machine

Interface (TIMI) and the iSeries Hypervisor. Within these operating-

system layers, AS/400* and iSeries servers implemented the

functions of a service processor and handled hardware resource

management, including dynamic LPAR support and Capacity

Upgrade on Demand (CUoD). This approach bundled these

technologies with the operating system, making them operating-

system dependent and tying them to a single server.

LIC and TIMI still exist, but some of the functions they provided

were moved to the server firmware and the HMC. The HMC is an

external firmware appliance that communicates to the FSP firmware

layer on the server using TCP/IP over Ethernet. The firmware

components include the following (see Figure 1, left):

• The HMC firmware provides converged platform configuration,

management and services.

• The Flexible Service Processor (FSP) firmware provides

diagnostics, initialization, configuration, runtime error detection and

correction.

• The Power Hypervisor (PHYP) firmware, which is based on the

iSeries Hypervisor, provides VLAN, virtual I/O and sub-processor

partitioning support.

• The Partition Firmware (PFW) supports the pSeries Power

Architecture* Platform Requirements+ (PAPR+) interface.

• The System Power Control Network (SPCN) firmware interfaces

with bulk power for power monitoring and control.

• The Bulk Power Control (BPC) firmware controls each bulk

power unit in Central Electronic Complex (CEC) and towers. This

firmware is specific to the i595, p590 and p595 systems.

It’s important to understand that the server firmware layers exist

and fix maintenance for server firmware must be managed. However,

for the purposes of the accompanying article we only need to

understand that the HMC is one component of the Global Firmware

and the HMC firmware maintenance process is independent from

the server firmware.

Depending on your availability requirements, you canattach a second, or redundant, HMC to the other FSP port. Thesecond HMC can be local or remote. Each HMC must use adifferent IP subnet. Repeat the aforementioned procedure foreach server that you want the HMC to manage. Now you haveredundant HMCs for all your POWER5 servers using just twoHMCs (see Figure 1, page 4).

Earlier I recommended two Ethernet adapters on the HMC.The recommended configuration allocates one adapter for theprivate network to the managed servers. The second adaptercould be assigned to an open network through which the HMC

could access other services, such as a DNS or gateway routerfor intranet or Internet access. Through this second interface,you could remotely access the HMC using the WebSM client,an i5/OS console session using any TN5250 emulator or theHMC command line using any SSH client such as PuTTY. TheHMC includes a built-in firewall that can be tailored to allowor disallow remote access.

If the Internet is accessible from this second interface, youcan configure HMC to report service events directly to IBMover a VPN connection, rather then over the modem. Theproblem-management task on the HMC can activate a browser

connection to the IBM Information Center to link to detailsabout the problem. Internet access also enables the HMC toelectronically download fixes or updates for both the HMCfirmware and the server firmware.

Because the HMC is completely independent from the server,the server and all partitions can remain active whilemaintenance is performed on the HMC, allowing you to easilykeep your HMC at the latest maintenance level. HMC updatescan be downloaded electronically or ordered on CD. Detailsare available on the HMC maintenance Web site(http://techsupport.services.ibm.com/server/hmc/power5). Alist of all of the currently available releases and enhancementsadded by release is also available online(http://techsupport.services.ibm.com/server/hmc/power5/tips/hmcprereqs.pdf).

Server-firmware maintenance generally requires a completeserver IPL. The default for firmware fix installation changesonce the HMC has been attached to the server. It’s imperativethat this be clearly understood. Details are available in thearticle, “An Introduction into Global Firmware & ConcurrentFirmware Maintenance” by Stephen Linam and BeckySchmieding (www.mcpressonline.com/mc?printarticle@8.gbNecuLEtdP.5@.6b26e4f1).

Briefly, there are two ways to apply server-firmwaremaintenance, and the method is determined by the FSPUpdate Policy setting. Note that when attaching an HMC toyour server, this policy is automatically changed from “OSManaged” to “HMC Managed.” In this state, firmware updatesmust be applied using the HMC. Beginning with the server-firmware enhancements in the June update, the

HMC Managed method allows “concurrent” firmware maintenance within a release. This means that the POWER5server can remain operational. The OS Managed method willalways require a complete server shut down for firmwaremaintenance.

HMC and Server Management The HMC provides multiple server-management facilities (seeFigure 2, page 6). The following is a partial list: Configuration management

• Guided wizard setup and online documentation• Server and partition configuration• Virtual I/O configuration• Capacity on Demand management• HMC setup and configuration

Operations management• GUI or command line, local or remote• Virtual operating system consoles• Virtual control panel for i5/OS partitions• Server and partition controls• Dynamic LPAR resource movement• Scheduled operations

Change management• Add/remove server hardware• Update your HMC and server firmware

Problem management• Hardware error-event collection, analysis and correlation• Gathering of extended debug data• Transmission of problems to IBM

Service Management• Guided concurrent repair procedures• Hardware inventory collection• Service utilities

It’s important to note that HMC backup and recoveryprocedures must be part of your systems-managementprocesses. The GUI interface to update the HMC firmware iswhere you’ll find the save tools. From here you can use “Backup Critical Console data,” which should be used wheneverconfiguration changes or firmware maintenance has beenperformed. The save can be to DVD-RAM media, an FTPserver or to a Network File Server (NFS). “Save Upgrade data”should be used immediately preceding an HMC-firmwarerelease upgrade.

HMC SummaryThe HMC is an external appliance that’s used to configure andmanage POWER5 servers. The HMC isn’t required on allPOWER5 servers. It’s required if you need or plan to use LPARor CUoD, and on all high-end POWER5 systems (e.g., i595,

Options for Ordering the HMC

The Hardware Management Console (HMC) is available in two

desktop models, the 7310-C03 or 7310-C04, or in two

rack-mount models, the 7310-CR2 or 7310-CR3. Functionally,

there’s no difference between these models. Minor differences

include the base number of Ethernet ports. For example, the

C03 and C04 come standard with a single Ethernet adapter. By

default, the IBM* configurator adds a second adapter for these

models. The rack-mounted versions, CR2 and CR3, come

standard with a two-port Ethernet adapter, which IBM

recommends. At this time, the HMC supports a maximum of

three. The keyboard and monitor are ordered separately.

To order the HMC, contact your IBM representative, an IBM

business partner or the Americas Call Centers at 1-800-IBM-

p590 and p595). It’s required when the server has dual FSPs. It can attach to a current maximum of 48 servers and

manage a maximum of 254 partitions. The HMC uses Ethernetto communicate to the FSP component of the server firmwareover an SSL-secure TCP/IP protocol. It has the ability to be theoperating-system console for any or all partitions that itmanages. For i5/OS partitions, this console session can beaccessed from any remote TN5250 client. The HMC GUIinterface can be accessed remotely from a WebSM client. Thecommand line can be accessed remotely from any SSH client.The HMC includes a firewall that can allow or restrict anyremote-access function.

HMC firmware is separate from the server-firmwarecomponents, allowing it to be updated without impacting theservers that it manages. It’s recommended that HMC updatesbe applied before the server-firmware updates. This ismandatory on the high-end servers.

The HMC provides a GUI interface to multiple managementtasks and has a robust interface to manage HMC userauthorities and accesses. It also provides a guided interfacefor hardware changes, tracking and analyzing problemevents and the ability to report service events for multipleserver and partitions.

The HMC uses Ethernet to communicate to the FSP component of the server firmware over an SSL-secure TCP/IP

protocol. It has the ability to be the operating-system console for any or all partitions that it manages.

Defining LPARs on an ^ i5 SystemWithout Using an HMC

I n addition to using the Hardware Management Console

(HMC) to create partitions, ^ i5 users may have

another option available to them. If you only need one i5/OS*

partition and no more than four Linux* partitions, you may use

the new Virtual Partition Manager (VPM) function.

VPM does have some additional limitations as well, but will

provide all of the function needed to load and run i5/OS and

guest Linux operating systems. The Linux partitions must use

virtual I/O resources that are owned by the i5/OS partition. With

the VPM, uncapped processor partitions can be created and up to

four virtual Ethernet connections can be defined. Dynamic

resource movement to/from the Linux partitions isn’t supported.

VPM support is included with i5/OS for no additional charge

and is provided via a PTF. The i5/OS PTF MF34753 (or it’s

supersede) is required to enable the VPM function. The

minimum firmware level required is SF230_126. This level of

firmware is indicated by PTF MH00312.

Small and medium business customers can utilize the VPM to

create Linux partitions for their infrastructure applications.

Customers that want to create multiple i5/OS, Linux and AIX* 5L

dynamic partitions; use direct I/O resources; and use advanced

partition management tools will continue to use the HMC for

partition management.

Details on the planning considerations and limitations of VPM

as well as a pointer to a Redpaper that fully describes the steps

for planning and implementing VPM can be found on the Linux

on iSeries Web site (www.ibm.com/iseries/linux/vpm.html).

Domino* on the iSeries* system

and server consolidation seem to

be synonymous. Each Domino

server on the iSeries system runs as a

separate subsystem, allowing multiple

Domino servers to execute on the same

system. The iSeries subsystem

architecture offers the significant benefit

of running applications because each of

these environments is segmented from

each other. This segregation means that

various applications can execute on the

same server, eliminating many of the

inter-dependencies that often exist for

other platforms.

We know the iSeries system is

scalable, reliable and easy to manage,

so let’s look at how migrating different

Domino infrastructures to the iSeries

system can benefit your business.

Migration scenarios showcase the

Server consolidation comes into play when implementingDomino on the iSeries system in many different scenarios.This article will examine the following examples:

1. Consolidating multiple Windows* Domino servers to oneor a few Domino servers on the iSeries system

2. Consolidating multiple systems hosting Domino serversthat need to live in “separate” environments (e.g.,Sametime, QuickPlace, etc.)

3. Consolidating Microsoft* Exchange server farms toDomino on iSeries systems

I’ll outline each of these scenarios and explain the benefitsand business case for each.

Consolidating Multiple Windows Domino Servers Consolidating multiple Windows Domino servers seems to bethe most common scenario when migrating Dominoenvironments from Windows to the iSeries system. Over thepast few years, several of my customers have chosen to havetheir Domino environments, which were initially implementedon Windows, migrated to their iSeries systems. This is a greatwin for the customer, allowing them to eliminate unnecessarysystems by consolidating their Windows Domino servers ontothe iSeries system they’re currently using to run their existingline of business applications.

Typically these Domino servers are providing mailfunctions. The majority of these customers haven’t branchedout into utilizing other collaboration components of Lotus*Domino such as workflow-based applications, Sametime orQuickPlace. For those who have, I’ll cover these scenarios inthe next section.

In migrating Lotus Domino to existing environments, thebiggest question is whether the existing iSeries system canaccommodate the additional Domino workload. In themajority of cases, it can. With iSeries performance increasing,the amount of capacity these systems can handle continues togrow. This makes it easier to migrate Domino to the iSeriessystem without spending extra money on big hardwareupgrades or new hardware implementations.

As long as the appropriate capacity planning has taken placeprior to the migration, this can be a smooth process. (Note:IBM’s ^ Workload Estimator is a good capacity-planning resource: www-912.ibm.com/wle/EstimatorServlet). I even have clients still utilizing green-screen5250 applications who have chosen to migrate their WindowsDomino mail servers to the iSeries system. Because of itsflexible computing environment, the addition of these totallydifferent types of workloads can have negligible impact on theperformance of existing applications, provided the appropriate

tuning is done prior to Domino infrastructure migration.I always do a detailed performance assessment of the

existing environment prior to recommending the addition ofDomino to the system. By examining the current CPUutilization, paging and fault characteristics, and disk andnetwork bandwidth, many performance problems can beavoided with the proper implementation architecture plan. Iattribute this to the robustness of OS/400*, which allows manydifferent workloads to execute together and may help reducethe overall total cost of ownership.

Occasionally customers may need to add memory, disk oran additional processor to their existing systems toaccommodate the new Domino workload. In my experience,even with this additional cost of hardware acquisition, it’s rarethat the cost of upgrading the existing system is outweighedby the multiple benefits of having all of the Dominoworkloads consolidated onto the iSeries system.

Consolidating Non-Mail Domino Servers Many companies are running Domino environments thatutilize more than e-mail. They’re using Sametime to provideinstant communication between employees and possiblyoutside contacts, improving employee productivity. I’ve alsoseen the usage of Sametime e-meetings grow substantiallyover the past two years. This function allows employees tocollaborate with contacts in multiple locations, eliminating theneed to travel to those locations to meet directly.

QuickPlace is another product that many organizations aretaking advantage of. These workspaces on the Web, enabledthrough the use of QuickPlace, provide collaboration areasthat have been changing the way companies do business. Forthose who haven’t utilized QuickPlace, this product allowsteams to jointly work on projects, even when team membersare separated by distance. Some of the biggest benefits ofQuickPlace are the fact that non-IT employees can easilycreate a QuickPlace and people from multiple companies canutilize these spaces on the Web to collaborate on projects thatspan different departments and organizations

Both QuickPlace and Sametime require separate Dominoservers to function properly. For most other platforms, thismeans using multiple boxes to support the infrastructure. TheiSeries system offers flexibility. A single iSeries system canaccommodate multiple Domino mail servers, Sametime serversand QuickPlace servers, all running on the same physical hardware.

When migrating these types of Domino infrastructures tothe iSeries system, companies generally see a reduction in theadministration required to manage these servers. Because allof the Domino servers can run on one system, minimal effortis required to keep the Domino servers at the same releaselevel. There’s only one Lotus Domino code load required for

N O V E M B E R 2 0 0 5 ^ M A G A Z I N E , A S E A N / S A E D I T I O N 15

the base underlying Domino product. Any fixes applied to thesystem to accommodate the Domino server code are directlyapplied to all instances of Domino servers.

Another benefit these types of installations can takeadvantage of is the multiversioning capability built into theDomino product on the iSeries system. Starting in LotusDomino 6.0.3 and 6.5.0 on the iSeries system, multipleversions of Domino can be installed on the same physicalsystem or LPAR. This means that not all servers must berunning the exact same level of Domino server code. This newfunction has proven to be valuable when consolidatingDomino servers to the iSeries system because it isn’t quite socommon for Windows technology-based Domino servers to allbe running at the same Domino version.

Microsoft Exchange Server Consolidations This particular scenario is growing rapidly. Several iSeriescustomers who have been using Microsoft Exchange for e-mail are re-examining this particular solution in light of thechallenge of upgrading all of these servers to MicrosoftExchange 2003. Not only is there a significant person-resource cost associated with this upgrade procedure, there’salso substantial expense associated with upgrading the serverenvironments to Microsoft 2003 and then subsequentlyupgrading all of the Exchange servers to version 2003. Thesecosts are causing many organizations to re-evaluate theiroptions and consider other, more robust e-mail environmentssuch as Lotus Domino.

Companies that choose to migrate from Microsoft Exchangeto Lotus Domino on the iSeries system can realize thefollowing benefits:

• Possible improved scalability as more users can run on aLotus Domino server on the iSeries system than on anExchange server

• Potentially a more stable environment with one or, atmost, a handful of servers to manage, compared tomultiple Windows servers

• One consolidated environment for the IT department tomanage rather than focusing on different boxes andloading patches separately for each server

• Consolidation of multiple Microsoft Exchange servers tothe iSeries system

• Better performance-data tracking for the servers and LotusDomino environment

• Ease of moving resources between servers because they’reimplemented on the same piece of hardware

Implementation Details Now that we’ve examined some of the more commonscenarios involved when migrating either non-iSeries Dominoservers to the iSeries system or Exchange to Lotus Domino on

the iSeries system, I want to cover some of theimplementation details that you’re likely to encounter whenperforming these types of migrations.

When you’re migrating Domino servers from other platformsto the iSeries system, you must take various considerations intoaccount. Often the biggest consideration is whether you’regoing to migrate the Domino servers one-for-one or whetheryou’re going to consolidate multiple Domino servers whenmoving to the iSeries system. Here are some of the methodsyou may choose to use when performing a migration.

Drop-and-replace method—It’s easiest to migrate each ofthe Domino servers individually to the iSeries system,basically performing a drop-and-replace type of migration. Inthis scenario, it’s best to adopt the same TCP/IP address foreach of the existing Domino servers. This avoids having toupdate desktops to ensure connection documents point to thecorrect TCP/IP address. It’s certainly not the end of the worldif you need to change TCP/IP addresses, but it addscomplexity to the migration.

If you choose the drop-and-replace method, the appropriateconfiguration files such as names.nsf, notes.ini, server.id,cert.id, dolcert.id and user.id (the administrator’s ID) must bemoved to the iSeries system so the new Domino server canadopt the correct characteristics from the existingenvironment. When moving these files, make sure theQNOTES user profile owns these objects once they’re moved tothe iSeries system. QNOTES is a special user profile createdwhen Domino was implemented natively on the iSeriessystem. This user profile must own all Domino objects in orderfor the server to function properly.

Consolidation of multiple Domino servers—If you havemultiple Domino servers to migrate to the iSeries system,you’ll most likely end up doing a combination of the drop-and-replace method and an actual consolidation of theDomino servers. The implementation details vary with thetype of work the Domino servers are performing.

For example, if you’re consolidating a Domino mail server,Sametime server and QuickPlace server, you must keep theseas three separate Domino servers on the iSeries system. Thebenefit here is that all three of these servers can be managedon one central server, rather than on three separate boxes.

If you’re migrating multiple Domino mail or applicationservers, you may want to also consolidate servers to a smallernumber of servers on the iSeries system. In this scenario, youmust make several choices. You can choose a two-stepapproach, which has the least risk. However, it prolongs thefinal cut-over to a full iSeries implementation. In this case,you’ll first migrate each of the individual Domino servers to acomparable Domino server on the iSeries system, adopting thesame TCP/IP address as in the drop-and-replace method, if atall possible. Once all of the Domino servers are migrated to

16 N O V E M B E R 2 0 0 5 ^ M A G A Z I N E , A S E A N / S A E D I T I O N

the iSeries system, you can start to consolidate them by usingthe AdminP function to move users from one mail server toanother. This migration provides little disruption to the endusers. The AdminP function is built into the Domino serverand performs a variety of services. If you’re unfamiliar withthe functionality of the AdminP task, refer to these LotusDomino domain articles: “All About AdminP Part 1” at www-10.lotus.com/ldd/today.nsf/ Lookup/AllAboutAdminP_1 and“All About AdminP Part 2” at www-10.lotus.com/ldd/today.nsf/Lookup/AllAboutAdminP_2.

Microsoft Exchange migrations—In this type of migration,there’s a considerable chance to consolidate onto fewerservers. Lotus Domino on the iSeries system generally offerssuperior scalability over Microsoft Exchange servers. Most ofthe Exchange servers I’ve seen only support 500 to 2,000users. These constraints are lifted with a Lotus Dominoimplementation. Domino Release 6 offers incrediblescalability, allowing thousands of users to run on the sameserver. These scalability benefits are expected to increase evenmore when moving to Lotus Domino 7, which is scheduled forgeneral availability in a few months.

An Exchange-to-Domino migration is more involved thanthe other types of migrations outlined in this article. Whenmigrating Microsoft Exchange users to Lotus Domino, notonly is there the actual server-migration piece, but also anend-user training component. For the most part, users will beable to pick up the Lotus Notes* client intuitively; howeverI’ve found the most successful implementations include somelevel of end-user training that provides a comparison betweenthe two clients. This helps prevent users from becomingfrustrated, spending precious time learning the many shortcutsthey knew on Outlook to address their e-mail, calendar andaddress-book requirements.

Some special considerations that should be taken intoaccount when migrating from Microsoft Exchange to LotusDomino include:

• Access to a more secure environment with potentiallyfewer virus concerns, especially when implementingDomino on the iSeries system.

• The ability to remove viruses from Microsoft Exchangemail files when performing the migration to LotusDomino. For example, the Binary Tree CMT migration toolcan enable this function, according to the company.

• Very seriously consider rolling out the Notes client ratherthan having users continue to use the Outlook client toaccess the Domino server. There are some limitations inthe co-existence of the Outlook client regardless ofwhether you use the Exchange Connector for Lotus Notesor the Domino Access for Microsoft Outlook connector.

• I also discourage the use of the Domino Web Access interface (formerly known as iNotes) as the primary

method for end users to access the Domino server. Whilethis interface provides a relatively robust Web experiencefor accessing mail, calendar and scheduling services, it’snot as rich as the Notes client.

No Looking Back I hope this article has provided the information you need tomove forward with a possible Domino server consolidation tothe iSeries system. Various scenarios exist where serverconsolidation comes into play. My customers who havechosen to migrate definitely haven’t looked back. They’vefound their new environments to be more secure, reliable andeasier to manage.

One scenario I didn’t touch on in this article is migratingexisting OV/400* environments to Lotus Domino on theiSeries. There are still some customers who haven’t been ableto move to a replacement for their OV/400 solutions. This scenario, along with the other scenarios I covered in this article, is part of the Tradeup to Lotus Software program(www.lotus.com/lotus/offering1.nsf/wdocs/move2lotus).

A look at customers’ success and achievements

Customer’s Testimonial

COMPANY PROFILEThin-film disks are the primary high-capacity storagemedium for digital data in computers and consumerappliances. Komag Incorporated has been a leadingindependent supplier of these disks since thecompany’s inception in 1983. While the company isheadquartered in San Jose, California, with an R & Dfacility in the San Francisco Bay area, Komagmanufactures all of its disks through variousproduction sites in Malaysia. Being at the forefront ofthe industry in terms of production volume andtechnological expertise, Komag’s success hinges onthe ability of its products to rapidly improve storagedensity at a low cost per gigabyte.

THE BUSINESS NEEDKomag manufactures product from a number ofdifferent sites across Malaysia with plants in Penang,Johor and Kuching. Combined, they are responsiblefor the company’s total global production output -which is rapidly increasing as it continues to gainmarket share. However, the growing need for a robust

data replication and backup solution - and therequirement for this to occur across a number ofdifferent sites - was becoming an increasing issue forChandran Supramaniam, Komag’s Director ofCorporate Information Systems. “To do a full backup,a complete shutdown of the application is required.We operate in a high pressure environment whereproduct ‘lots’ move quickly from one process to thenext. The ability to monitor this movement to thelevel of accuracy required was just not possible whenan application shutdownoccurred. The replicationsolution I required wastherefore one that couldcopy data to anothermachine and thenperform a backup fromthat replicated copy. Inthis way we could keepour application goingwhile doing the backup.”Chandran’s decision wastherefore based on abalancing act between wanting minimal downtimeand ensuring that the end-result was in line with theexacting requirements of his business.

Turning to IBM i5s and *noMAX Synergy *noMAX was recommended to Chandran by a localIBM Business Partner and Authorised MaximumAvailability Reseller, Sunway Computer Services.Komag installed the *noMAX garrison software on

their iSeries server for the primary purpose of enablingproduction to continue being monitored while key databackup takes place. Senior Information Technologist YLWee says that the *noMAX solution requires minimalmonitoring and that by taking advantage of the RemoteJournaling capabilities of the OS/400 there is little need toallocate human resource to run the solution.Because of growing production volumes,Komag recently upgraded their IBM iSeriesservers to a combination of a new i5 servermodel 550 and 520. “The migration of*noMAX as part of this upgrade wasflawless,” says Chandran. The idea that the*noMAX solution can grow in parallel withany iSeries upgrades and the business ingeneral is one of its most appealing factors.“We simply get what we need today withoutcompromising future IBM platform development or*noMAX’s ability to scale to the business need. It’s a greatcombination.”

“The ability to easily migrate to a more comprehensive

solution as-and-when required was an important factor asit provided a clear roadmap for the company,” saysChandran.

The OutcomeFaced with a requirement to drive and manage a rapidly

growing business, and having to replicatedata across different sites and at the sametime reduce backup downtime - Komagsought a High Availability solution that wasboth flexible and cost-effective. “We needed astraight forward yet powerful backup solutionthat could be quickly deployed, focus on ourexact specifications, expand as we grow anddeliver against a price point that was relativeto the business, which is why we went withthe *noMAX solution.”

“Making sure that we have piece of mind when it comesto the replication of our data is crucial. The *noMAX teamare a pleasure to work with and the product has not let usdown,” concludes Chandran.

O ver the years, this column has profiled selectindividuals in the iSeries* realm who tout interestingmusical backgrounds and collections. We profiled Jim

Worthen, a former member of the 1960s rock quartet “TheAmerican Breed,” who sang backup vocals and played backupguitar for the Acta Records version of the hit song “Bend Me,Shape Me.” And we profiled Maurice O’Prey, who maintains a15-guitar (and growing) collection that includes a rare FenderJaguar Cars Stratocaster.

In the name of musical-instrument diversity, we turn thismonth to Buck Calabro, an iSeries guru in his own right, whoalso happens to be, quite probably, the only person in theiSeries community who owns and plays a Chinese erhu, a two-stringed fiddle of sorts that was a gift his brother picked up ona trip to China. Although it would be cool to refer to Calabroas an “erhu guru,” he admits that he’s only adequate with theinstrument.

“I don’t play it as well as I’d like, but I can keep up,”Calabro says.

The erhu is the most unique instrument in Calabro’s rathereclectic string-instrument collection, which includes a violin,viola, cello and acoustic guitar. He also covertly plucks at hisdaughter’s bass guitar (when she’s not around, of course).

Calabro’s musical talents were evident at an early age. Hefirst showed an aptitude for string instruments in second gradeat the age of 7 when he started tuning his violin by himselfrather than relying on his teacher.

“My good pitch sense didn’t help me with my bowing or finger skills though,” he says. “I still sounded like any other7-year-old beginner.”

Later, at the age of 12, Calabro’s teacher brought to schoolhis viola to play duets. It was that instrument, with its richsound, that got Calabro forever hooked. Throughout thefollowing years, Calabro gradually discovered he simply had aknack for picking up assorted stringed instruments and wasjust innately able to play them. Ironically, his experiences inthe midrange-computing field came about in much the sameway, with Calabro working as a computer operator in 1978—right out of high school—on a System/3 model 12. From there,it was just like tuning a violin—well, sort of.

“For whatever reason, I read the RPG manuals and tried thelanguage out,” Calabro says. “Soon I was maintaining codeand eventually writing my own. We did all our software in-house, and did programming for other folks, too. I gainedexperience on the S/32, S/34 and S/36* through our outsideprogramming, and when the System/38* was introduced, webought one.”

According to Calabro, he occasionally hears that quite a fewprogrammers are musicians, pointing to a possible linkbetween the patterns in music and the patterns inprogramming, a link he feels is fairly plausible.

“One of the things that I find is that the discipline in musiccarries over to my coding,” he explains. “There’s room for freeexpression in music and in code, but it must be contained insome rational framework in order to be enjoyable and useful.”

Although he’s primarily a stringed-instrument enthusiast,Calabro also dabbles with his jazz and chromatic harmonicas,and he’ll occasionally tootle a few tunes on his wife’s recorder.The one wind instrument he’d particularly enjoy is the GreatHighland Bagpipe, much to his wife’s dismay. As a birthday-gift compromise, she gave him parlour pipes (scaled-downversions of the Great Highland Bagpipe), which are quietenough to play indoors in their Schenectady, N.Y., home.

But Calabro’s true instrumental love remains the viola, aninstrument he says reflects much of his own personality, atleast when it comes to programming.

“One thing that strikes me about my favorite instrument, theviola, is that it’s an ensemble instrument,” he says. “From aprogramming perspective, that means that I prefer to workwith the rest of my team, in harmony with them.”
