Re: IBM Shark ESS disks - anyone used them?

["Charly Jones" <charly301@xxxxxxxxxxx>]

Cheap drives are something to consider in a SAN because of
RAID and mirroring and data redundancy.  I have been told that RAID
originally meant "redundant array of inexpensive disks."  IBM
had a problem with "inexpensive" and has promoted "independent"
as a better choice.

V5R1 and the fiber IOP is what makes this interesting.  The 6501
controller is very old and very slow.  The fiber IOP is rated at
100 megabytes per second and will probably increase to 200
megabytes per second when everyone signs off on the new standard.

I think the disk situation may change fairly quickly...
