IBM System DS4200 Express
The IBM System Storage DS4200 disk storage system supports a high-performance 4 Gbps FC interface for increased host connectivity to deliver necessary bandwidth for high throughput applications. Designed for data-intensive applications that demand increased connectivity provided by four 4 Gbps host channels designed to provide up to 1550 MBps of sustained bandwidth for high throughput applications through the four channels directly attached to the host servers or connected to a Fibre Channel storage area network (SAN).
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 input/output per second (IOPS). 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.
On the host side, if a server requires more than two 2 Gbps host bus adapters (HBAs) to attain the required performance (a server should have at least two HBAs for availability), then that number can be halved with 4 Gbps. Fewer HBAs help lower the number of switch ports used.
