I know performance benchmarking is an art. And asking questions like
"how can I test this new storage" may bring a smile on face of some of
you. But still...

The time has come and I need to replace the disk storage underlying
the DB/DISKCLASS/FILECLASS files. I'm going to test two storages from
Infortrend and DDN. Both storages allow mix and match of SAS (for
DB/LOG) and SATA (for DISK/FILECLASS) drives.
Both will be FC 4Gb attached.
I've been thinking about replicating my biggest TSM server (Linux
based) on a server that has been put aside for this purpose.  I'll
load DB/LOG onto SAS drives and some FILECLASS volumes onto SATA
drives and time the following workloads:
- expiration
- db defrag
- Reclamation

To be honest I am not sure I know how to properly set up such testing
environment. I'm concerned that my tests will not be representative
enough and will not indicate the actual performance that I'll observe
after the storage system will become production.

Your thoughts on this topic are much appreciated...
