Product Description
The Lenovo 4XB0F28645 is a powerful 6Gb SAS Host Bus Adapter (HBA) based on the LSI9280-8e controller, specifically designed to enhance the storage capabilities of Lenovo ThinkServer systems. This high-profile card features eight external SAS ports, utilizing SFF-8088 connectors, which are standard for connecting to external disk arrays, JBOD enclosures, and other high-density storage solutions. Each of the eight ports operates at a data transfer rate of 6Gb/s, providing substantial bandwidth for demanding storage workloads. This HBA is equipped with hardware RAID capabilities, supporting a comprehensive range of RAID levels including RAID 0, 1, 5, 6, 10, 50, and 60. This allows for the creation of highly redundant and high-performance storage configurations directly on the adapter, offloading processing from the host CPU. It typically includes a significant amount of onboard cache memory (e.g., 512MB or 1GB) to further accelerate RAID operations and improve overall storage performance, making it suitable for mission-critical applications and large data sets. The high-profile form factor ensures compatibility with standard server chassis that have full-height expansion slots. The 4XB0F28645 is an ideal solution for businesses looking to expand their storage capacity with external arrays, offering a reliable, high-performance, and feature-rich option for data-intensive environments within the Lenovo ecosystem.
