The 5.2.2 Performance Tuning Guide says:
"NTFS file compression should not be used on disk volumes that are used by
the TSM server, because of the potential for performance degradation."

We use client compression so I don't think it would buy us anything.

Report back if you try this out!

Subject: disk storage pools and windows compressed file systems

Have any of you used disk primary storage pools which use windows
compressed file systems? Comments on performance, etc?

We are investigating use of a multi TB raid5 array to use as a buffer
between our local primary disk pool and the tapepool. Have seen the
posts regarding file vs disk device classes but what about compression?
Good, bad, etc.

Win 2000 sp4 with TSM server 5.2.3.2
