SGI S330 RAID Features

2
The SGI S330 RAID system uses Serial Advanced Technology Attachment (SATA) disk drives
instead of Fibre Channel (SCSI-protocol) disks.
While the form and function of the SGI InfiniteStorage TP9300 and the SGI S330 are very similar,
it is important you note the following:
• The SGI S330's serial ATA drives are not compatible with TP9300 Fibre Channel
(SCSI-protocol) disks and SGI S330 disks should never be used as spares in TP9300 drive
arrays.
• Fibre Channel (SCSI-protocol) drives cannot be used as spares in serial ATA enclosures.
• The 2822 RAID controller interface in an SGI S330 will be different than a 2882 RAID
controller interface found in InfiniteStorage TP9300 units. The difference can be confirmed
by special marking or part numbers on the RAID controller canister.
– The 2882 RAID controllers cannot be used as spares or replacements for 2822 RAID
controllers.
– The 2822 RAID controllers cannot be used as spares or replacements for 2882 RAID
controllers.
• The SGI S330 drive enclosure's front bezel will always be a different color (black) than the
Fibre Channel (SCSI-protocol) array (InfiniteStorage TP9300) enclosure. The drive handles
on the SGI S330 also should be grey.
• The serial ATA drive enclosure will have a different storage capacity than a Fibre Channel
(SCSI-protocol) array using the same number of disks.
• The expansion enclosures contain environmental status modules instead of RAID
controllers. Each environmental status module contains an environmental services monitor
board (ESM) and two slots for SFPs (small form-factor pluggables). The ESM board is the
interface between the controller enclosure and the expansion enclosure. The ESMs used in a
TP9300 are not interchangeable with those used in the InfiniteStorage S330.
• The drive interface (ESM) in a SGI S330 controller will be slightly different than those in
the TP9300. The difference can be confirmed by special marking or part numbers on the
SATA drive interface.
• Serial ATA ESMs and Fibre Channel (SCSI-protocol) ESMs are not interchangeable.
