The IBM System Storage DS4200 Disk Storage System offers customers a SAN solution to take advantage of the performance offered by 4 Gbps technology. The IBM DS4200 4 Gbps SAN product is designed to offer up to 1550 MBps throughput with up to 121,500 IOPS (input/output per second). A 4 Gbps storage array requires as few as half the number of ports compared to a 2 Gbps storage array to deliver equal throughput. This frees up ports in the SAN for each array.
