- Ultra3 (Ultra 160/m) SCSI (160MBps per RAID channel) PCI RAID controller card for Compaq ProLiant servers with 256MB cache memory and RAID 0
- 5 and Advanced Data Guarding support
Designed and tested with industry-standard ProLiant Servers for greater reliability, this controller is ideal for the distributed workgroup server or centralized departmental server, and like other Smart Array controllers, the SA-5304 offers complete data compatibility with previous generations’ Smart Array controllers for easy data migration and upgradability.
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.
(Note: RAID ADG is a standard feature of SA-5304 and available as an option to other models. RAID ADG requires a minimum of 64-MB battery-backed cache.)
Modular, easy-to-upgrade design lets you optimize performance and increase capacity, as needed, from two to four channels and with 32-, 64-, 128-MB or 256-MB battery-backed cache.
High-performance, Fifth generation architecture offers the new hardware RAID engine, and a new performance memory architecture for increased performance over previous controllers.
Recovery ROM protects against a ROM failure or corruption.
Ultra3 SCSI technology delivers high performance and data bandwidth up to 160MBps bandwidth per channel.
Up to 4 channels provides one of the highest storage capacity per PCI slot in the industry.
Mix-and-match LVD SCSI compatibility protects your investments and lets you deploy drives as needed.
Battery-backed Cache protects cached data in the event of a power outage, server failure or controller failure, and redundant, replaceable batteries take that protection even further. Maximum cache configuration is 256-MB of battery-backed cache.
64-bit, 66-MHz PCI interface boosts bandwidth up to a 533MBps total transfer rate.
64-bit memory addressing supports servers with greater than 4GB of memory.
Online Management Features: Online Capacity Expansion, Online RAID Level Migration, Online Stripe Size Migration, Multiple Online Spares (Global), User Selectable Read/Write cache, User Selectable Expand and Rebuild Priority SAN Access, an integrated SCSI controller and Fibre Channel SAN adapter offers centralized, consolidated backup solutions and incremental SAN based primary storage for groups of 5-10 servers driving Direct Attach Storage (SCSI) with Smart Array 5302 Controllers.
