The LSI Logic LSI20320-R Ultra320 SCSI single-channel host adapter is the right choice for increasing storage performance within servers and high-performance workstations. With 320MB/s throughput and capability of up to 50,000 I/Os per second, this adapter is ideal for quickly moving large amounts of data. Designed to provide a dedicated connection to Ultra320 disk drives or storage enclosures, the LSI20320-R delivers sensational performance.
This card also provides for increased reliability and performance with on-board Integrated RAID [0 (striping), 1(mirroring), and 1E (enhanced mirroring)]. LSI Logic Integrated RAID is hardware-based and operating system independent resulting in exceptional performance without requiring special drivers.
