Purchase and Implementation Process

Pre-requisites1. Upgrade to SAP NetWeaver 7.02. Perform Sizing via QuickSizer (recommendation: use

services provided by SAP AGS “SAP Quality Check”)

PurchasingProcess

1. Contact SAP Account Executive for BWA license2. Contact hardware partner’s AE for ordering

BWA hardware

Installation byHardware Vendor

1. Hardware Partner ships and installs BWA appliance2. Some on-site configuration might be necessary

Post-installationSet-up

1. Identify InfoCubes and index them2. Recommendation: Configuration Check for BWA (as

part of SAP Quality Check for BWA)

For further services provided by SAP AGS or consulting, please see SDN!

QuickSizer

BWA Sizing integrated in SAP QuickSizerQuickSizer access: http://service.sap.com/quicksizerCreate Project and select SAP NetWeaver BW

Create a new QuickSizer project, otherwise the BWA options willnot appear.Most of the data captured is the same as for SAP NetWeaver BWsizing. If you have already performed a BW sizing, you can Copy& Paste the values for the BWA sizing.

If you already have a BW system (loaded with data), then the programand method described in SAP note 917803 is recommended

Report computes memory requirements and disk space (also runson SAP BW 3.x)

Using the BWA will take load off of the SAP NetWeaver BW system.As this load reduction depends on several detailed factors (such asshare of query time spent in analytic engine, size of result set, numberof users etc.), this reduction has not been captured in the SAPNetWeaver BW sizing.Refer to Thread on SDN posted by Marc Bernard for some additionalinfo

Appliance FAQMemory

Which memory setup is supported for BWA blades?See matrix for release status of blade generation and memory. Most up-to-date information can befound in PAM: http://service.sap.com/pam --> NW 7.0 (see attached ppt)Please see additional information for Nehalem CPUs in SAP note 1363917.For mid-size customers, the HW partners offer one XS configuration consisting of 8GB/12GB blades.This offering provides best value at reasonable hardware and license costs.Any combination of blade generations can be used in the same BWA system.

Appliance FAQStorage

Why is the storage part of the BWA appliance?The storage as part of the appliance has some significant advantages:

Rapid and instantaneous deployment (preinstalled hardware and minimal configurationeffort)Optimal performance configuration through highly integrated hardware and softwaresetupReduced cost of operation (minimized and centralized maintenance)Support only involves SAP and the HW partner, not a third party – support can behighly specialized and tailored on the complete offeringHigh Availability (switch-over) may depend on the storage and cannot be offered out-of-the-box using other storage systems

© SAP 2007 /

Appliance FAQOptimizing the Appliance Investment

I have done some investments into the blade infrastructure. How can I optimizethis infrastructure?

An existing rack including the power source can be used for all SAP NetWeaver BWAccelerator and SAP NetWeaver Enterprise Search appliances.

Appliances are available in several sizes. Be sure to choose the right size under thefollowing aspects

Do not undersize the system in order to be prepared for the futureDo not oversize the system to avoid investments into ‘empty’ and unused hardware.

Performance, supportability, high availability, security etc. can only be guaranteed by bothSAP and hardware partners, if you strictly stick to the appliance set-upNote: any changes to the standard appliance set-up require additional effort and aseparate project; a pre-installed delivery from factory cannot be guaranteed. Performance,supportability, high availability etc. have to be ensured by the customer and/or theimplementation partner.

Bladeholds several holds several

Appliance FAQBW-BWA Connection

Do I need 1:1 relationship between BW and BWA?The only supported configuration for productive systems is a 1:1 connection between theBW instance and the BW Accelerator to ensure uncompromised performance of BWA.In order to maximize the value of the investment, you can install several BWA instances inone rack – utilizing the existing infrastructure. For production systems, it is required tohave dedicated storage (disk controller) and network connection (switch) to ensure thathigh load on one BWA instance is not impacting performance of the other instance.Several BWA instances can be installed in one BladeCenter/enclosure on project basis.

Appliance FAQSharing the Blade Infrastructure

What further options do I have for test environments?Ideally, the components of the infrastructure are exactly sized to the system needs, so that there is noneed to deviate from the appliance definition.Note again: any changes to the standard appliance set-up require additional effort/costs and a separateproject; a pre-installed delivery from factory cannot be guaranteed.As non-productive systems typically have less requirements towards high performance and disastertolerance, following components may be shared on project basis:

Storage and network connection (in addition to rack and BladeCenter/enclosure)Blades, only if you do not need several test BWA systems in parallel (but sequentially)– Note that only one active BWA installation per blade is supported at a time (is connected to

exactly one BW instance)– You can install several (inactive) BWA systems on one blade– Activate the BWA system that you need for a given period of time and rebuild the BWA index on

it (for more information, please refer to SAP note 979609)

Note that reorganization or restart of one BWA instance may affect all connected BW systems.

Appliance FAQMaintenance and Support

Who maintains and supports hardware, software and OS of the BWA?BWA software support is included in the SAP service feeAdditional support contracts are highly recommended:

Hardware partner offers contracts for hardware maintenance; ask for tailored BWA support offersNovell offers enhanced support for SUSE Linux in collaboration with SAP Linux Lab ('SUSE PrioritySupport for SAP'). This offer facilitates communication and ensures seamless support at highquality particularly for BWA customers. Please check www.novell.com/sapsupport for moreinformation.

The maintenance and support process is organized in the same manner as other SAP productsSoftware issues are handled by SAP, and the link to hardware partners is via Linux Lab.The customer is responsible for applying patches and support packages or for contracting this workto third parties.Note that OS patches need to be released by the HW partner!

Central monitoring and administration toolIndex SettingsPossible actions– Restart BWA server: restarts all the BW Accelerator servers and services. This

includes the name server and index server– Restart BWA index server: restarts the index server. (The name servers are not

restarted.)– Reorganize BWA landscape: If the BW Accelerator server landscape is unevenly

distributed, this action redistributes the loaded indexes on the BW Acceleratorservers

– Rebuild BWA indexes: If a check discovers inconsistencies in the indexes, you canuse this action to delete and rebuild all the BW Accelerator indexes.

Checks– Connection Check– Index Check– Etc.
