The LSI Logic LSI20320 Ultra320 SCSI single channel host adapter is the right choice for increasing internal storage performance within ISP, rackmount servers, and high performance workstations. With 320 MBps and capability of up to 50, 000 I/Os per second, this adapter is ideal for transferring high speed and high capacity data. Designed for applications that don't require as many external connections, this cost effective solution gives you the performance you need, at a price that is right. Popular applications include print, email and web servers, and intranet and extranet hosting. With PCI-X throughput of 1056 MBps, this adapter also capitalizes on maximum system performance for those systems needing it; yet is backward compatible with existing PCI systems. It features LSI Logic SureLINK domain validation technology ensuring data integrity by intelligently testing the network before completing negotiation. It also utilizes Fusion-MPT architecture that allows for thinner drivers for better performance (up to 50, 000 I/Os per second) while adding value and flexibility at the firmware level.
