4 Gbps Fibre Channel interface technology
The IBM System Storage DS4800 disk storage system supports a high-performance 4 Gbps Fibre Channel 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 Fibre Channel storage area network (SAN).
Designed to help lower your total cost of ownership
The IBM DS4800 4 Gbps SAN can impressively offer up to 1724 MBps throughput with up to 575,000 input/output per second (IOPS) from cache. This frees up ports in the SAN for each array, which can help lower your cost of ownership.
On the host side, if a server requires more than two 2 Gbps host bus adapters (HBAs) for availability, that number can be halved with 4 Gbps. Fewer HBAs help lower the number of switch ports used and can help reduce overall cost.
IBM DS4800 4 Gbps technology is backward compatible with 2 Gbps and 1 Gbps. You can add new technology incrementally rather than replacing your entire SAN with 4 Gbps technology. Note: 4 Gbps products will slow down to 2 Gbps or 1 Gbps if they are connected, but zoning can allow a rolling upgrade strategy with minimal disruption.
