The MegaRAID SCSI 320-2X offers system builders a robust and powerful RAID solution designed around a high-speed PCI-X host interface for maximum data throughput and fault tolerant data protection. The highly flexible design features two internal and two external Ultra320 SCSI connectors for maximum storage connectivity. Its a half-length form factor offers space-saving configurability for today's rack-mount and appliance chassis architectures.

By leveraging a powerful yet reliable RAID engine with advanced features, including: 64-bit addressing support, flexible memory and caching policies, easy-to-use management utilities, and quick installation and setup capabilities, the MegaRAID SCSI 320-2X is quickly becoming the preferred Ultra320 RAID solution of OEMs, system integrators and value added resellers (VARs) worldwide.
