Our production env constitues 9206 / 4 node RAC on SUSE9/Sun v40z AMD Opteron servers with 16GB SGA each. Earlier we used to be on Redhat 3 on Dell PowerEdge 6650/intel Xeon 32bit where SGA could go upto 4GB with hugemem kernel. End Users saw a definate improvement in response time in the ERP thats running on top this DB.
We will buy an new server.
SO will be RHEL 4 AS/ES
1) HP 585 4x AMD Opteron
2) HP 580 4x Xeon
Any reference, idea, experience about these 2 alternatives ???
What about SGA limit ?
I think I can make a huge SGA with AMD64 (no 3 GB limit),
Do I have this limit in Xeon 64 bit ?
