The Smart Array 5300 series of high performance Ultra3 array controllers provides improved flexibility and data protection thanks to an innovative modular design and new Advanced Data Guarding - RAID ADG technology. In addition it again raises the bar to higher performance levels with several enhancements that include a new memory architecture and new RAID engine.

Key Features:
Advanced Data Guarding (RAID ADG) offers breakthrough level of fault protection of RAID volumes up to 2TB and a total of 56 disk drive in a RAID volume. RAID ADG provides fault protection greater than RAID 1 or RAID 5 and only consume the capacity of 2 disk drives for distributed parity data. RAID ADG protects against any 2 disk drive failures. This higher level of protection is ideal to protect large logical volumes and with high capacity disk drives where a failed drive rebuild time may be significant.
