Think twice before wasting your storage budget on SAS disks. Studies conducted by Google and Carnegie Mellon have proven that SCSI and SAS drives are no more reliable than SATA drives. Modern SATA drives have a huge cache buffer so the next block is already in
cache, and the faster RPM won’t generate anything but extra heat – something you don’t want in your RAID.

If you need high availability
you need a solution with no single point of failure. Putting dual controllers into an iSCSI SAN may double the cost, but it won’t eliminate a single point of failure. If you have a single chassis, you have a single point of failure in the backplane. Cybernetics’ high availability solution includes two complete miSAN units with NO single point of failure.
