So I figured I'd kick off the discussions here with something I have yet to find consensus on... how do you evaluate what your proposed storage for your Oracle on VMware VM is going to support?
Do you use the I/O Analyzer fling from VMware's labs ( http://labs.vmware.com/flings/io-analyzer ) ? If so, which I/O profile do you use? OLTP 8K ?
Do you use the I/O Calibration built into Oracle 11g ( https://community.emc.com/community/connect/everything_oracle/blog/2012/01/12/using-io-calibration-to-assess-oracle-io-stack ) ?
Do you just wing it and see what happens?
