First rule of thumb, don't guess. Since Oracle SGA can be anywhere from a few hundred megabytes to 10's of gigabytes, you need to size the server larger than the SGA. If you undersize the server, you WILL have undesirable performance. On intel they size based on low cost of storage and I/O avoidance so generally are too large. The SGA is usually oversized as well - BUT the oracle DBA will need to be involved as that is the person that can reduce the SGA size. There are ways to measure existing storage requirements, guessing without measurements is playing roulette (1 out of 38 you guess right?)....

We have a project that is being setup to run on RHEL under z/VM. The sizing parameters for the
guests (Oracle DB, and WebLogic) are being sent to us based on intel platform sizing. How do some of you handle the sizing conversion from Intel to IFL's? Are there some rules of thumb, we should know about?
Our environment: IBM z10-BC (QA and Dev) and z10-EC (Prod) running z/VM 5.4 and RHEL 5.3.
