4 Gbps FC interface technology
The IBM System Storage DS4800 disk storage system supports a high-performance 4 Gbps FC interface. Increased host connectivity delivers the necessary bandwidth for high-throughput applications. Designed for data-intensive applications that demand increased connectivity, eight 4 Gbps host channels can help provide up to 1724 MBps of sustained bandwidth, allowing for high-throughput applications through eight channels directly attached to the host servers or connected to a FC storage area network (SAN).
Designed to help lower your total cost of ownership (TCO)
Take advantage of the performance offered by 4 Gbps technology with IBM System Storage DS4800. Two ways to measure performance of an SAN device are MBps and input/output per second (IOPS). The IBM DS4800 4 Gbps SAN can impressively offer up to 1724 MBps throughput with up to 575,000 IOPS from cache. A 2 Gbps storage array can require twice as many host ports as a 4 Gbps array to deliver the throughput of four 4 Gbps ports. This frees up ports in the SAN for each array.
On the host side, if a server requires more than the minimum of two 2 Gbps host bus adapters (HBAs) for availability to attain the required performance, that number can be halved with 4 Gbps. Fewer HBAs help lower the number of switch ports used and can help reduce overall cost.
