•
The InfiniteStorage 350’s 3992 RAID controllers cannot be used as spares or replacements
for other SGI RAID controllers.
•
The expansion enclosures contain environmental status modules (ESMs) 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 the 16-slot disk expansion units are
not
interchangeable with
those used in the SGI 14-slot disk expansion enclosures.
•
The ESMs in the enclosures can be swapped with those used in the InfiniteStorage 4000
units as they also support Fibre Channel (SCSI-protocol) drives.
Performance Features
The SGI InfiniteStorage 350 RAID storage system has the following basic features:
•
Support for cost effective (SATA) drive array technology.
•
Continuous availability, with constant monitoring and optional redundancy of all active
components.
•
Dynamic scalability, making it easy to grow RAID disk resources without disruption.
•
Superior connectivity, allowing simultaneous connections to multiple servers directly or by
way of storage area networks (SANs). Support for optical host connections.
•
Large storage capacity with support for up to 48 drives.
•
Storage management facilities for installation, configuration, expansion, and monitoring.
•
Redundant power supplies and hot-swappable components.
•
Upgradeable to meet a variety of RAID requirements.
•
Integrated RAID controllers.
•
Battery backup for cache data.
Note:
The InfiniteStorage 350 controller enclosure and it’s 16-slot disk expansion units use a
switched bunch of disks (SBOD) technology. This functions in a manner similar to an FC-AL
switch, allowing the controller to establish point-to-point connections between a disk and the
controller.
