Analyzing IO at the Exadata Cell level… a simple tool for IOPS.

Lately I have been drawn into to a fare number of discussions about IO characteristics while helping customers run benchmarks.  I have been working with a mix of developers, DBAs, sysadmin, and storage admins.  As I have learned, every group has there own perspective – certainly when it comes to IO and performance.

  • Most DBA’s want to see data from the DB point of view so AWR’s or EM works just fine.
  • Most System Admin’s look at storage from the Filesystem or ASM disk level.
  • Storage Admins want to see what is going on within the array.
  • Performance geeks like myself, like to see all up and down the stack <br />
