going from SCSI to SATA setup in Dell Poweredge

Hi,
  We just bought a refurb Dell Poweredge server with support for SCSi Drives and a built in RAID. However the prices of SCSI drives are pretty high and we are thinking of getting SATA drives with controller card. I need some direction into which Hard drives would work and what card to get.

we need to know what system you have, as there are several poweredge models.  Truthfully, scsi disks are faster and more reliable...by the time you buy the sata controller and sata drives, you might end up spending about the same amount of money.

Its a 2450 with P3 860mhz processor and 2GB of RAM
tfjeffCommented:
oh, dell will provide no assistance with a sata controller in that system, you are better off doing one of two things:
1) Stay with scsi raid
2) Buy a new server

adding sata to that system would be difficult, the backplane in that system only supports scsi, and to put a sata hdd into one of the hdd slots the backplane would have to be removed and in most of those 2u rack servers from dell the backplane is required to post the system.

Could you explain this more "backplane is required to post the system."
jamietonerCommented:
if the backplane is not in the system it wont turn on, im not sure if the 2450 is one of them but the 2850, 2650 and 2550 all require the backplane the contain part of the systems ESM (embedded systems managment)

hmm, I guess it makes sense to stay with SCSI drives. I have 1 36 GB harddrive on the system which has all the OS and Applications installed. If I were to get another 36 GB drive and do a Hardware Raid 1 would I have to format both drives and re-install the OS or would the data be replicated on the second drive?
jamietonerCommented:
yes, going from scsi to scsi raid is destructive, you would need to reinstall the os and put the data back on from your backup
