I/O workload generator

[alanhast]

We would like to compare our IBM Shark disk against our HP Storageworks disk with our AIX servers. We've used Intel's Iometer utility for our Windows servers. Iometer is an I/O workload generator and performance analysis tool dedicated to server-level performance testing.

Does anyone know of a similar product that works on AIX?

if you are on aix 5.2 you can get stats per adapter with iostat -a, i would also recommend NMON and the excel counterpart.

To generate I/O you can use some dd on raw devices, so you will avoid the LRU cache interference which can greatly modify each result.
