Sata Raid 1 to SCSI Raid 5?
I need to change my server for it to use SCSI Raid 5 instead of SATA Raid 1 in HOTSWAP. Is there a way to make it happen? I wouldn’t mind buying the SCSI controller…
In a word, No.
Raid 1 is mirroring (requires 2 drives).
Raid 5 is striping with parity, requires 3 or more drives.
Second, SATA is the technology your controller and drives use to communicate. The drives won’t magically change if you add a SCSI controller. You would need to purchase a SCSI RAID controller ($400-1000) and 3 or more SCSI hard drives. Running all this equipment you’d want to make sure you have a large enough power supply (probably 500-1000 watts) and enough drive bays for all of the equipment.
Oh, and you’ll probably have to reload your operating system.
Oh finally- the hotswap backplane (the board your hotswap drives connect to) may not have SCSI connectors on it– SATA uses 7 pins for data and 4 for power. Hot swap SCSI drives use 80 pins and are totally incompatible.
