IBM has announced a new SAS disk cabinet. Previously we were limited to a 12 disk cabinet (the EXP12S) but IBM now has the EXP24S, a 24 disk cabinet. With 24 front facing Gen2 (SFF-2) bays for SAS disk, these connect to SAS PCI adapters and are supported on the following OS’:
AIX 5.3 or later
IBM V6R1 or later (With or without VIOS)
LINUX REHL 5.6 or later, SUSE 11 or later
VIOS 2.2.0.12 or later
It is important to understand the configuration limitations as once shipped the disk distribution cannot be changed:
– 1 x set of 24 disks will support AIX, i/OS, Linux and VIOS using all SAS disk controllers
– 2 x set of 12 disks will support AIX, Linux and VIOS but NOT i/OS using all SAS disk controllers
– 4 x set of 6 disks will support AIX, Linux and VIOS but NOT i/OS using only #5901 or #5278 SAS controllers
The EXP24S use with i/OS must be checked to ensure that sufficient performance is
achievable with all 24 disks installed, though it should be possible to have less than the full 24 disks installed if performance is a concern.
The EXP24S comes with fixed rails also so OEM racks may be a problem. We expect OEM rails at a later date.
Whilst great to have a better density disk rack, caution is required when configuring all 24 disks on a single controller.
