The LSI SAS 9212-4i4e host bus adapter (HBA) provides the greatest available throughput to internal server and external storage arrays through high-speed 6Gb/s ports, supporting up to 256 SATA and SAS physical devices. It bolsters server storage RAID and non-RAID enclosures by pairing an x8 PCI Express 2.0 host interface with one external x4 SFF8088 Mini-SAS connector and four internal x1 SATA connectors.
This HBA utilizes the embedded CPU in the LSISAS2008 controller to perform integrated RAID 0, 1, 1E and 10 operations for reliable data protection with high-availability. The result is an ultra-thin, low-overhead device driver communicating over the x8 PCI Express 2.0 host interface. By reducing RAID code overhead, this HBA delivers high-speed READ/WRITE performance, making it well suited for medium to high-capacity internal storage applications.
