Product Description
The LSI Logic LSI20320-R is a high-performance RAID controller that combines the speed of the Ultra320 SCSI interface with robust RAID functionality. This card is engineered for server environments and demanding workstations where data availability, performance, and redundancy are critical. The Ultra320 interface provides a theoretical maximum throughput of 320 MB/s, ensuring rapid data access for storage subsystems. As a RAID controller, the LSI20320-R supports various RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for performance and redundancy), and RAID 10 (striped mirrors for performance and redundancy). This flexibility allows administrators to configure storage arrays that best meet their specific needs for speed, data protection, or a balance of both. The card typically features onboard cache memory, which further accelerates I/O operations by buffering frequently accessed data. Its PCI-X interface ensures high bandwidth communication with the host system. The LSI20320-R is a powerful solution for building reliable, high-performance storage systems capable of handling intensive workloads.
