This unique expansion system provides the fastest data transfers from multiple servers to storage available on the market today! With high speed PCI Express (PCIe) Gen 3 technology read transfers can reach 2700MB/s and writes 2200MB/s. This is almost twice what competitive products can boast. A PCIe x8 cable plugs into the rear of the server and then plugs into the PCIe cable connector on the rear of the chassis. Optionally, two SAS x4 cables plug into the SAS x4 connectors connect the host server to the two SAS connectors on the rear of the RAID array. Both can be input connections to two servers or one can be an input and the other an output to connect another RAID array, thereby doubling the storage capacity and increasing the performance.
