64-bit PCI-X Ultra320 SCSI Dual-Channel Host Bus Adapter - LSI21320-RB / PCI-X, U320, 2Ch IR Supp
Dual-Channel with Flexible Connectivity
The LSI21320-R Ultra320 SCSI dual-channel host adapter is ideal for workstations and servers needing a high-performance boot volume and connectivity to legacy devices, tape backup, or external storage. The
LSI21320-R features two independent Ultra320 SCSI channels allowing a combined maximum throughput of 640MB/s. With support for up to 30 devices it offers incredible flexibility in system configuration. The LSI21320-R supports all previous generation SCSI devices and is backward compatible to 32-bit, 33MHz PCI. This makes the LSI21320-R a great option whether used to upgrade an existing system or optimize a new workstation or server.
Exceptional Signal Integrity
The LSI21320-R not only moves data blazingly fast, it also insures unmatched data reliability and signal quality. With LSI Logic TolerANT™ technology, the card improves data integrity in less than ideal
cabling environments. SureLINK domain validation verifies that all devices are able to communicate at the negotiated SCSI transfer rate and optimizes the connection between the card and each device on the
bus. The net result is exceptional data reliability optimized performance.
Powered by Fusion-MPT
Based on LSI Logic’s Fusion-MPT (Message Passing Technology) architecture, the LSI21320-R provides outstanding I/O performance while allowing extremely high host processor efficiency. Fusion-MPT permits
an exceptionally thin device driver that’s common to all Fusion-MPT devices used in a given OS.
OS Independent Hardware RAID (0,1)
LSI Logic Integrated RAID provides the reliability and performance benefits of disk mirroring (RAID 1) and striping (RAID 0).
Integrated Mirroring™ (IM) provides data protection for the system boot volume by simultaneously writing redundant data across two to six disks. This provides fault tolerance and safeguards critical information. Integrated striping yields enhanced performance by
aggregating the bandwidth of up to six disk drives. Integrated Striping provides a significant boost in applications where maximum performance is essential. LSI Logic Integrated RAID is OS-independent and does
not require the use of special device drivers.
Dependable Quality and Reliability
For more than 15 years, LSI Logic has provided high-performance SCSI HBA
solutions to leading server, disk array, and systems providers worldwide. Using only the highest quality components, LSI Logic
host adapters are assembled and tested in world-class facilities to assure superior product reliability and performance.
Because of stringent quality management programs, our host adapters carry a threeyear limited warranty.
Wide Range of OS & System Support
The LSI21320-R supports all key 32-bit and 64-bit versions of Microsoft Windows, Linux, Solaris and x86, IA64, SPARC, and AMD64 system architectures. With this broad base of OS and system support, the LSI21320-R is the ideal choice for attaching the most powerful hard disk drives and SCSI peripherals to your workstation or server.
