Our organisation is considering Serial Attached SCSI (SAS) disks in a Hitachi
USP-VM for our mainframe environment instead of the usual Fibre Channel disk.
Anyone using SAS disk in the mainframe world?
Any comments regarding performance, throughput?
Performance does not depend directly on the HDD interface. If you
compare the same HDD family with different interfaces - it could make
sense. In other cases you try to compare apples and oranges.
DASD performance strongly depends on other factors like cache,
controllers, external interfaces, etc.
Generally I wouldn't expect problems with performance.
Last but not least: your question likely comes from plan to cut the
costs. In this case I would strongly consier other options, possibly
much more cost effective.
