[U2] SATA SAN question
Hi, We are looking at IBM's new DS4200 storage device for use with our unidata database but have been pushed away from SATA by an IBM sales partner. I was wondering if anyone has tested using SATA drives for their database or know of a reason not to. Thanks!

RE: [U2] SATA SAN question
From what I've heard, scsi is much better than sata for large databases as it sorts the request for data in sector order before beginning retrieval, resulting in better throughput in multi user environments. Sata is fast, but doesn't sort the requests, so it's great for single user systems due to lower cost. But Mongo only pawn in world of data storage ;) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of George Roehsner Sent: Friday, September 22, 2006 12:40 To: u2-users@listserver.u2ug.org Subject: [U2] SATA SAN question Hi, We are looking at IBM's new DS4200 storage device for use with our unidata database but have been pushed away from SATA by an IBM sales partner.

RE: [U2] SATA SAN question
I think newer SATA controllers and drives (SATA II) support native command queue (NCQ) requests, which make them comparable to SCSI for server environments (e.g. the 3Ware 9000 series). NCQ allows a drive to re-order commands and process them in proximate (data) order instead of received order. /Scott Ballinger Pareto Corporation Edmonds WA USA 206 713 6006 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Allen E.
