New "Modular Storage solution" is based on 6GB/s RAID or HBA with 2400MB/s pipe from 1x4-lane (1-port) of Gen2 PCIe x8 slot and will support up to 24 drives. One port can extend to 240 drives or 10-M cable length if capacity is needed. Two port allows failover, data recovery, or even load balancing with MPIO modules. Modular Storage with external JBODs to Host machine is more flexible and expandable. Email us at "xxera@xxera.net" if you have any questions. Thanks.
