Enviromental Requirements

Table 1.4 Environmental Requirements

+15°C to +32°C (59°F to 89.6°F) site temperature

40% to 55% relative humidity

0 to 2439 meters (0 to 8,000 feet) above sea level operating altitude

Air Quality Requirements

EMC products are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b.

The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.

The allowable relative humidity level is 20 to 80% non condensing, however, the recommended operating environment range is 40 to 55%. For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.

For facilities below 40% relative humidity, it is recommended to use grounding straps when contacting the equipment to avoid the risk of Electrostatic discharge (ESD), which can harm electronic equipment.

As part of an ongoing monitoring process for the corrosiveness of the environment, it is recommended to place copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity), in airstreams representative of those in the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put in place.



This EMC® cabinet ventilates from front to back; you must provide adequate clearance to service and cool the system. Depending on component-specific connections within the cabinet, the available power cord length may be somewhat shorter than the 15-foot standard.

Figure 1.1 Access and Ventilation Requirements

Optional Securing BracketsIf you intend to secure the optional stabilizer brackets to your site floor, prepare the location for the mounting bolts. The additional brackets help to prevent the cabinet from tipping while you service cantilevered levels, or from rolling during minor seismic events. The brackets provide three levels of protection for stabilizing the unit.

• Anti-Tip Bracket

• Anti-Move Bracket

• Seismic Restraint Bracket

Optional Securing Brackets 5


Anti-Tip Bracket

Use this bracket to provide an extra measure of anti-tip security. One or two kits may be used. For cabinets with components that slide, EMC recommends that you use two kits.

Figure 1.2 Anti-Tip Bracket Placement

Anti-Move Bracket

Use this bracket to permanently fasten the unit to the floor.

Figure 1.3 Anti-Move Bracket Placement



Seismic Restraint Bracket

Use this bracket to provide the highest protection from moving or tipping.

Figure 1.4 Seismic Restraint Bracket Placement



Cabinet PositioningThe cabinet bottom includes four caster wheels. The front wheels are fixed; the two rear casters swivel in a 1.75-inch diameter. Swivel position of the caster wheels will determine the load-bearing points on your site floor, but does not affect the cabinet footprint. Once you have positioned, leveled, and stabilized the cabinet, the four leveling feet determine the final load-bearing points on your site floor.

Figure 1.5 Cabinet Positioning

When the cabinet is centered over two typical 24 in. (60.96 cm) by 24 in. (60.96 cm) floor tiles:

• Cutouts should be 8 in. (20.32 cm) by 6 in. (15.24 cm).

• Cutouts should be centered on the tiles, 9 in. (22.86 cm) from the front and rear and 8 in. (20.32 cm) from sides.

Cabinet Positioning 8


Package Dimensions and ClearanceMake certain your doorways and elevators are wide enough and tall enough to accommodate the shipping pallet and cabinet. Use a mechanical lift or pallet jack to position the packaged cabinet in its final location.

Figure 1.6 Door Clearance

Leave approximately 2.43 meters (8 feet) of clearance at the back of the cabinet to unload the unit and roll it off the pallet.

EMC DCA Getting Started Guide – Chapter 3: Gathering Site-Specific Information

3. Gathering Site-Specific Information

In order to complete an installation of an EMC Greenplum DCA, the following information should be gathered from the customer’s network and database personnel. The following sections are included:

• Site Requirements Checklist

• Plan for Hadoop Networking

• Planning for Remote Support - ESRS and Dialhome

Site Requirements Checklist

Table 3.1 Site-Specific Information

Information Description

External IP and hostname of the primary master

This is the IP address and hostname that the customer will use to connect to the primary master host from their public LAN.

The master hostname is also used for client connections to Greenplum Database.

External IP and hostname of the standby master

This is the IP address and hostname that the customer will use to connect to the standby master host from their public LAN.

Virtual IP Address A Virtual IP Address (VIP) is required to use master server failover features. A VIP will simply be a third external IP address . In the event of a master server failure, the VIP will moved from primary to standby master server. This should be the IP address client tools connect to.

If the subnet and gateway for the VIP differ from the other external IP addresses, this should be collected also.

External IP and hostname for DIA hosts

An IP address and hostname is required for each DIA host. The source data will be transferred to the DIA through this connection. Four IP addresses and hostnames are required per DIA module.

Netmask Netmask of the customer’s network.

Gateway Default gateway of the customer’s network and the IP address and interface name of the router.

NTP server IP The IP address or hostname of the customer’s preferred NTP (Network Time Protocol) server.

DNS name server IP The IP address of the customer’s DNS name server.

iDRAC password This is the password used for remote access to the master, standby master and segment hosts using the integrated Dell Remote Access Controller (iDRAC) interface. The default iDRAC password is calvin.

root password Customer supplied root password for the master, standby master and segment hosts. The default root password is changeme.

Site Requirements Checklist 12


gpadmin password Customer supplied Greenplum Database superuser password. The default gpadmin password is changeme.

System locale The preferred locale to be used on the master, standby master and segment hosts. en_US.UTF-8 is the default locale for the Greenplum DCA (U.S. English and Unicode character set encoding).

A locale identifier consists of a language identifier and a region identifier, and optionally a character set encoding. For example, sv_SE is Swedish as spoken in Sweden, en_US is U.S. English, and fr_CA is French Canadian. If more than one character set encoding can be useful for a locale, then the specifications look like this: en_US.UTF-8 (locale specification and character set encoding).

System timezone The local timezone to be used on the master, standby master and segment hosts. The default timezone is PST.

Database character set encoding

UNICODE (UTF-8) is the default character set encoding for Greenplum Database (server-side encoding). This is usually the best choice, as it allows the customer to store all possible Unicode characters from any language, but if all data you are storing is from a single language (now and in the future), it does entail a slight storage space penalty compared to an encoding specific to that language.

If the space savings is key, the customer should consider Latin-1, Latin-9, or WIN1252 for US or Western European installations, since those encodings use a single byte per character. Likewise in Thailand you might consider WIN874 to store Thai, since it uses a single byte per character. However, keep in mind that this prevents storing any data outside those character sets. Even in the US or Western Europe, customers might find that some of their data is Latin-1, while some is Latin-9 or Win1252, so any choice of single-byte encoding will not accommodate all of their data needs. See the Greenplum Database Administrator Guide for a list of all supported character set encodings.

Software Tools Connection to the DCA for setup and management requires an SSH utility. EMC recommends Putty or Cygwin.

Hardware Tools The following hardware tools will be required during installation of the DCA:

• Utility Knife

• 9/16’’ Socket Wrench

• ESD (electro-static discharge) kit

Power Connection for Service Laptop

Power for external devices should not be drawn from the DCA cabinet. A power connection is required for the EMC personnel service laptop. The connection should be a standard AC 100-240V~1.5A, 50-60hz outlet.



Site Requirements Checklist 13


Plan for Hadoop NetworkingHadoop modules have specific networking requirements. It is important to plan these requirements with the customer prior to an installation - Hadoop services cannot be started without the proper networking configuration.

Item Description

Hadoop Namenode Virtual IP Address Virtual IP Address to use for Hadoop namenodes. This IP address will move to the standby namenode during a failover.

Custom VLAN ID VLAN ID

IP Addresses for VLAN IP addresses to use for Hadoop nodes. The amount of addresses required depends on the total number of Hadoop nodes being deployed.

Netmask for VLAN The netmask for IP addresses on the VLAN.

Gateway for VLAN The gateway IP addresse for the VLAN.

Table 3.2 Hadoop Networking Requirements

Dial-home and ESRS Connectivity

The DCA supports dial-home for event notification to EMC Global Services support center. Communication from the DCA to EMC is done via FTPS. Firewall access should be setup to allow FTPS traffic from the DCA’s external IP address to the following EMC addresses:

corpusfep3.emc.comcorpusfep4.emc.com

The DCA also support remote support through an ESRS Gateway. If the DCA is to be setup in an environment with ESRS, the Gateway IP address should be identified prior to installation. The DCA supports FTP, SMTP and HTTPS connection types to the ESRS Gateway.

Ethernet Connections to Network

The DCA connects to a network through the master and standby master servers. Two ethernet connections are required to the master and standby master server. Ethernet cables for external connections are not included with the system.

DIA modules connect to the network through an ethernet connection on each DIA host. Each DIA module requires four connections (1 per server).



Plan for Hadoop Networking 14


Planning for Remote Support - ESRS and DialhomeThe Greenplum DCA supports remote support and dialhome through EMC Secure Remote Support (ESRS) as well as secure direct dialhome. Use the following information to plan remote support for the DCA.

ESRS Considerations

Review the following considerations for implementing remote support on DCA through an ESRS gateway:

• The ESRS Gateway must be running a minimum version of 2.08

• Port 22 between the ESRS Gateway and DCA must be open to allow for INCOMING support - from the EMC Support Center.

• SMTP is supported for OUTGOING (dialhome) support. Port 25 must be open between the ESRS Gateway and DCA for SMTP support.

• FTP is supported for OUTGOING (dialhome) support. Port 21 must be open between the ESRS Gateway and DCA for FTP support.

• HTTPS is supported for OUTGOING (dialhome) support. Port 443 must be open between the ESRS Gateway and DCA for HTTPS support.

Secure Direct Dialhome Considerations

Review the following considerations for implementing dialhome on the DCA directly to EMC - using the FTPS protocol:

• The DCA must have access to corpusfep3.emc.com and corpusfep4.emc.com using the passive FTPS protocol. The passive FTPS protocol uses ports 990 to establish a connection and a dynamic port range of 20000-30000 to transfer data.

• OUTGOING (dialhome) support only, INCOMING is not supported.
