Re: Ultrium 3280 SAS Tape Drive on RX2800 - Restores times very slow
To verify that the adapter is the culprit here, I would confirm by using the same test on a system with an adapter that has the cache enabled. If the adapter is the problem, then the new test should show a significant performance difference. Also, as stated by Hoff, process quotas etc can significantly affect Backup performance. For the confirmation testing, be sure that the accounts, quotas etc be consistant.

robert70,
Battery:
Battery is not reported as present.
That could be a reason. Storage controllers typically don't allow you to use WRITE caches, if there is no battery available !

Or the battery has failed; cache batteries have been known to do that.
Call hardware services.
Your organization pays good money for that access into HP, use it.

Check the battery cable connection. I have seen these get dislodged. Even a re-seat might help.
These batteries run about $60 or so.
