Hi Steven, We did a similar upgrade just over a month ago, and things run 5 times faster now. Disk writes had been a limitation for us, too.
We went to an HP EVA 8000 SAN cabinet from a Compaq ESA 12000 box that had an HSZ 80 (SCSI) controller. Also upgraded the servers from DEC Alpha 4100 to Alpha ES47. Software was UD 5.1.28 on Tru64 4.0f, now UD 5.1.28 on Tru64 5.1b We were using RAID 0+1 (striped mirrorset) containers for our high-transaction data on the old storage, so created them as RAID 1 on the EVA. RAID5 containers stayed as RAID5. As always with Pick data, sizing the files with reasonably-correct modulos works wonders for maximizing I/O performance. Good luck and have fun with the upgrade, Tom >>> [EMAIL PROTECTED] 09/19/06 1:16 AM >>> Hi - we currently run unidata on tru64 5.1 with san attached storage consisting of several raid volumes This is a Compaq MA8000 with HSG80 controllers . We are going to move all this to a HP EVA san using virtual disk. Just wondering if anyone else has this. We have a 25GB RAID5 and a 50GB RAID5 volume, each is used for separate applications. One app does fairly intensive billing tasks writing thousands of small transaction records, per hour so I am concerned that performance will not drop.
