Sizing for BW Front-end

Query results from different frontend processors:

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

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.
