The LSI LSI22320-R Ultra320 SCSI Dual Channel host adapter delivers the speed and bandwidth required by today's data intensive storage applications. With 640 MBps and capability of up to 100, 000 I/Os per second, this adapter is ideal for enterprise servers and high performance workstations working in environments where data intensive, high capacity and high availability applications are being used. It also features Integrated Mirroring for increased data protection. Today's most popular applications include data warehousing, video streaming, Internet, email, printing, financial management and other storage intensive applications.The LSI22320-R adapter features two independent Ultra320 SCSI channels allowing an aggregate SCSI speed of 640 MBps. It supports up to 30 external/internal devices for the greatest flexibility in a SCSI solution. With PCI-X throughput of up to 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 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 100, 000 I/Os per sec) while adding value and flexibility at the firmware level. This flexibility and rich feature set makes options like Integrated Mirroring, instantaneous physical mirroring of boot drive for volume and OS protection, available.
