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,
Brian
