Benefit
|
|
Multiple On-board processors
133 MHz 5x86 microprocessor
Dual RAID coprocessors
|
Maximizes data throughput by separately executing RAID commands, parity operations and data caching
|
|
PCI-to-PCI Bridge architecture
Two independent, on-board PCI buses
|
Increases overall controller performance compared to single bus controllers by allowing multiple operations to be performed concurrently. One to optimize microprocessor activities and the other for data transfers
|
|
Single-ended
Differential
Fibre Channel
|
Choice of host interface technologies
|
|
Supports RAID levels 0, 1, 3, 4 and 5
up to 4 arrays per controller and up to 8 drives per array
|
Build arrays with RAID levels to meet specific performance and data protection needs
|
|
Hot-swap drive support
|
Replace failed drive without interrupting data access
|
|
On-line, hot-spare with auto-rebuild
Up to 2 dedicated hot-spare per array
|
Return to full fault-tolerance without human intervention
|
|
Dynamic sector repairing
|
Automatically and transparently maintains data integrity and access by assigning data on a bad block to a spare sector on the disk
|
|
Array verification
|
Maximizes data reliability by detecting and repairing bad data before it is read by the host server
|
|
5.25 inch Half Height Canister
|
