Benefits |
Advanced Data Guarding
(RAID ADG) |
Delivers fault protection for RAID volumes up to 2 TB
Keeps data available and server running while a failed drive is being replaced
Protects large logical volumes and high-capacity disk drives where rebuild time for a failed drive could be significant
Supports up to 56 disk drives in a single RAID volume
Withstands two simultaneous drive failures without downtime or data loss
|
Distributed Data Guarding
(RAID 5) |
Allocates parity data across multiple drives (up to 14) and allows simultaneous write operations |
Disk mirroring
(RAID 1, 1+0) |
Allocates half of the disk array to data and the other half to mirrored data, providing two copies of every file |
High-performance 64-bit
architecture with superscalar
RISC processor |
Provides improved performance over previous controllers
Delivers new hardware RAID engine and new performance memory architecture
Offers much lower TCO than any other server storage RAID products
|
| Recovery ROM |
Provides redundancy that protects against ROM failure |
| Ultra320 SCSI technology |
Delivers high performance and data bandwidth of up to 320 MB/s per channel |
| On-line spares |
If a drive failure occurs, recovery begins using up to four spare drives so data can be reconstructed automatically |
| Up to four SCSI channels |
Provides over 8.2 TB of storage from a single PCI slot
Supports up to 56 hard drives
|
Battery-backed, ECCprotected
cache memory |
Protects data up to three days in the event of power failure or server hardware failure
Includes redundant batteries for greater cache protection
|
New performance
memory architecture |
Offers tri-directional data flow for improved performance |
| 256 MB and 128 MB cache module with chip recovery |
Protects cache memory from a single chip failure and multi-bit errors from any single memory chip |
