RE: Solid State Hard Drives
Hi Rodolfo
Currently the HP DL360 using SCSI Ultra 320 in RAID1 configuration.
If Solid State disks work as expected then the new mail server will be SATA2
using Solid State disks with either software or hardware RAID10.
Any thoughts on software vs hardware with Solid State disks? I'm thinking
software may be quicker and more reliable as there is no intermediate Cache
RAM as would exist on a hardware RAID controller.
If Solid State disks are not appropriate for a mail server then will use SAS
with hardware RAID10.
Kind regards

Hocking,
Which is your actual disk I/O technology. Is it SAS, SCSI or
SATA?
