Hi,   can someone tell me if i can use sata drives in the MD1000 ? (i don't need the fast sas drives, i would prefer 500gb sata drives)   http://www.lsilogic.com/technologies/industry_standards/sas_pages/sas_benefits.html     Benefits of SAS :   Universal connection- works w/ SAS and SATA drives   Message Edited by stephanvh on 05-22-200603:37 AM

Per the Dell Website: Drive BaysHolds up to 15 SAS drives   Only SAS drives are supported.   http://www.dell.com/downloads/global/products/pvaul/en/pvaul_md1000_specs.pdf   I'm sure the backplane can handle either SAS or SATA drives, but the carrier you get for the drives will only support SAS drives.  If you were to buy a MD1000, you'd see on the EMM 'ONLY SAS DRIVES SUPPORTED'. Message Edited by Storagetalk on 05-22-200607:18 AM

At present Sata is not supported on the MD1000. Although sata disks will fit in the SAS carriers and any 9th gen server disk carrier, they will sit proud of the enclosure a bit.   There will have to be a firmware and management software release to support sata. Probably once the technology has matured a bit and teething problems are sorted.

There is actually an issue that SATA signal strength is not upto SAS specs so they have to address that problem. I'm not entirely sure how they are going to do it but I understand that SAS/SATA mixed support is comming soon.

The MD1000 doesn't come with a sata to sas bridge, so a dongle or interposer board (bridge) will be fitted onto the sata drive which will then plug into the array. The drive carriers have two sets of mounting holes, one for SAS and one for SATA. The sata holes are further back to take in the board.

At present there are only laptop 2.5 in sata drives which are not robust enough for server enviroments. When better drives arrive they wil appear in servers and storage.

SATA II disks are now supported on the MD1000 since 6/30 with 250GB and 500GB sizes available. SATA II disks use an "interposer" card which provides the drive and signaling for SAS subsystem compatibility.
