RAID Features
The InfiniteStorage 350 RAID system is a mass storage system using serial ATA (SATA) disks
exclusively. All drive arrays in the RAID must be SATA attached. No intermixing of fibre channel
expansion units is supported. Also, no intermixing of fibre channel disks within the controller unit
or SATA expansion units is supported. The InfiniteStorage 350 RAID does support the following:
•
1-GByte cache per RAID controller canister for a maximum of 2-GBytes per RAID
controller enclosure.
•
16 SATA disk drives are pre-installed at the factory in both the RAID controller enclosure
and the optional disk expansion enclosures.
•
Each dual-controller RAID enclosure uses two 4-Gbit per second front-end host ports per
controller module, for a total of four host ports.
•
One or two optional SATA disk expansion enclosures can be attached to the “back-end” disk
channels.
Important:
The RAID controller canisters used with the SGI InfiniteStorage 4000 products
cannot
be interchanged with the controllers used in the InfiniteStorage 350 products.
While the form and function of the InfiniteStorage 350 is similar to other SGI SATA-based RAID
products such as the TP9300S, it is important you note the following:
•
Older serial ATA drives (such as those used in TP9300S or TP9500S) are
not
generally size
(data capacity) compatible with the InfiniteStorage 350 disks and should never be used as
spares in InfiniteStorage 350 drive arrays.
•
Fibre Channel (SCSI-protocol) drives cannot be used as spares in SATA enclosures.
•
The 3992 RAID controller interface used in an InfiniteStorage 350 has a different form
factor than RAID controllers used in the interface on older SGI RAID products. The
difference can also be confirmed by special marking or part numbers on the 3992 RAID
controller canister.
