The 12 Gbps Adaptec SmartHBA 2100-16i Host Bus Adapter has 16 internal SAS/SATA ports in a x8 PCIe Gen 3 low-profile, MD2 form factor and uniquely combines the capabilities of a full-featured host bus adapter (HBA) with those of a basic RAID adapter using hardware RAID. Built on the Microchip SmartIOC 2100 SAS/SATA protocol controller, HBA 2100 adapters can aggregate the performance of devices to the limits of the PCIe Gen 3 host bus at 6.6 Gbps, and achieve up to 1.7M IOPS without additional overhead or latency. The HBA 2100 adapters also have 40 percent power savings compared to previous generations, and significant power advantages versus competing solutions.
