Обсуждение: The HP MSA20 SATA-SCSI enclosure
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Being an HP/Compaq shop, I'm looking at an Opteron-and-SATA-based DL145 G2 and an MSA20 SATA enclosure with a U320 interface to use with RHES4 and PostgreSQL. Anyone have Experience with this h/w+s/w combo? It will be used as a "history server", so sub-second transaction times are not required. - -- Ron Johnson, Jr. Jefferson LA USA Is "common sense" really valid?

I recently speced this exact hardware for a customer. When the customer called HP to order, HP told them that it is not appropriate for a database. They cited shorter life of the SATA drives and overall performance. Is it true? I don't know. I have used SATA enclosures for databases for sometime and have been quite happy with them. You may also to look at the ml30 which is SCSI. Sincerely, Joshua D. Drake > > Anyone have Experience with this h/w+s/w combo?

SCSI, though, would push the costs excessively high. We have a Hitachi 9500 (really a DF600F) SAN, with SATA disks in it, as well as an older SCSI SAN, and the DF600F works well. We've had it for at least 2 years (time loses all meaning when you're a corporate drone...), and TTBOMK, it doesn't suffer abnormal disk deaths. What SCSI hba did you spec? - -- Ron Johnson, Jr. Jefferson LA USA Is "common sense" really valid?

Anyone else have experience with the MSA20 or the SmartArray 6404? >> Anyone have Experience with this h/w+s/w combo?
