BW Sizing Strategy: T-Shirt Model
SAP AG 1999
Sizing for BW Front-end
Query results from different frontend processors:
refresh runtime for selected TopN workbook

50
100
150
200
250
1000 2000 3000 5000 7500 10000

450 MHz, 128MB
180 MHz, 128MB
450 MHz, 64MB
180 MHz, 64MB
If enough physical memory is available and the query returns a small to medium sized result set, the refresh time will be similar even if the processor speed varies greatly from low to high.

Planning the BW Installation
Rough estimate of BW installation time:
Pre Installation Planning 0.5 day
BW Installation 1.0 day
R/3 Plug-In Installation 0.5 day
ITS installation 0.5 day
Post Installation tasks 1.0 day
Other Project Work 0.5 day
Additional System Admin Work ?

BW Pre-Installation: Disk Configuration and Layout
Example BW Disk Configuration using RAID 1 and RAID5:
Operation System -
RAID1
DB, SAP SWAP - RAID1
Redo Logs - RAID1
Mirrored Redo Logs -
RAID1
PSAPTEMP - RAID 1
SAPDATA - RAID5
BW is a READ based system rather than an UPDATE based system.
RAID 5 generally provides better READ performance than RAID 1.

BW Installation Sequence: Same as R/3
Install the database software
The actual database schema will be created during R3SETUP
Check database filesystem after installing DB software
Many subdirectories should exist
Install online documentation
(provided on kernel CD, along with instructions for setup)
Install R3SETUP
Run R3SETUP
Check environment variables
Creates the database <SID>
Use logs for troubleshooting
Check services, SAP filesystems
Perform post-installation tasks

BW Setup: Maintain Data Transfer Parameters
Maintain entries in customizing table RSADMINC
Packet Size is in KB and determines the size of Idoc data packages of data loads from flat file data sources and data loads from BAPIs. A setting of 20000 is the standard recommendation.
FrequencyStatus-IDOC is a ratio. The setting determines the frequency that status Idocs are sent.
