We are running a SSA 102 on a Sparc 1000e with 3 Oracle databases on it. We are using the Veritas VM software, and had a lot of trouble early on. Our MTBF was just under 3 weeks. We have not had any problems since we installed the latest patches from Sun, 10 weeks ago.

We have a 120 (concurrent) user 10Gig DB on RAID5, with 3:1 Read/Write ratio, and the average write time is 30ms.

You still have to shut down an SSA to replace a disk, and Veritas VM does not always start a hot spare when you loose a part of your RAID5 volume - it will stay in degraded mode until you manually do something about it; but the system is working fine here.
