Product Description
The LSI Logic LSI00303 is a versatile SAS RAID controller card designed to offer reliable storage performance and data protection for a variety of server and workstation applications. It utilizes the 6Gb/s SAS interface, providing a good balance of speed and compatibility for connecting SAS and SATA drives. The controller connects to the system via a PCI Express 3.0 x4 slot, offering sufficient bandwidth for many storage configurations, particularly in systems where a full x8 or x16 slot might not be available or necessary. This controller typically supports a number of internal drives, often up to eight, making it suitable for smaller server configurations or workstations requiring RAID capabilities. It provides hardware RAID support for common levels such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 10 (striped mirrors for performance and redundancy), RAID 5 (striping with parity for balanced performance and redundancy), and RAID 6 (striping with dual parity for enhanced redundancy). The inclusion of onboard cache memory, often 512MB or 1GB of DDR3, is crucial for accelerating RAID operations and improving overall system responsiveness. The LSI00303 is a cost-effective solution for environments that need robust data protection and improved storage performance without the extreme bandwidth requirements of 12Gb/s SAS or higher drive counts. It is a popular choice for entry-level servers, workstations, and storage appliances where reliability and efficient data management are key requirements. Its compatibility with both SAS and SATA drives offers flexibility in drive selection.
