AIX 5L's HACMP on Database Servers


Hello everyone,

I've been looking around for information on a 4 node SAP ERP/Oracle RAC architecture for AIX 5L and I'm being constantly lead to vendors being responsible for the clustering requirements.

I'm trying to setup a 4-server ERP architecture. Based on documentation provided in the SAP service marketplace, IBM's General Parallel Filesystem (GPFS) and PowerHA/HACMP is needed.

The following is our Production architecture...

2 Application Servers for SAP ERP Applications (clustered active-active)

- and -

2 Database Servers + External Storage mounted identically onto both (RAC Clustered)

I'm not sure how GPFS and PowerHA/HACMP will be distributed onto the 4 servers.

I would like to humbly ask the SAP implementation experts to please confirm this setup I've planned.

2 App Servers = PowerHA/HACMP

2 DB Servers = GPFS + Oracle Clusterware

Is it a requirement to implement PowerHA/HACMP and GPFS on all 4 of my servers?

Help would be greatly appreciated.

Many Thanks,
