Disk Array Features
Supported RAID Levels:
• RAID 0 – striping for performance
• RAID 1 – disk mirroring
• RAID 0+1 – mirrored stripe set
• RAID 5 – striped data + parity
• JBOD – single drive
Hardware XOR accelerator
Offers sustained data transfers up to 266MB/sec
3
Supports up to four logical drives
Supports variable stripe block sizes
Supports standard Serial ATA drives
Identical hard drives are recommended
Supports Logical Block Addressing
Large LBA support for drives above 137GB
Drive fault detection
Drive roaming during power-off
Bad block handling
Synchronization can be scheduled via management software periodically for
RAID array data consistency
Supports hot-swap of failed drives
Supports hot-spares
4
Offers transparent data recovery and rebuilds drive in background
BIOS/Driver support for rounding actual drive capacities to nearest gigabyte
5
Data handling optimizations include tagged command queuing, elevator seek
and load balancing
Arrays are bootable with built-in BIOS
Supports the BIOS Boot Specification
Optimized caching algorithm for parity calculations (RAID 5)
Remote monitoring of all arrays from network stations
Local maintenance of arrays with drag-and-drop support
Monitors enclosure temperature, fan, and power (SuperSwap only)
3
Depends on hard drive speed.
4
Requires standby disk of equal or greater capacity.
5
Allows for replacing a failed drive with a drive of a slightly less capacity (within 999 MB
difference).
