IBM System Storage DS4800

IBM DS4800 4Gbps technology is backward compatible with 2Gbps and 1Gbps. You can add new technology incrementally rather than replacing your entire SAN with 4Gbps technology. Note: 4Gbps products will slow down to 2Gbps or 1Gbps if they are connected, but zoning can allow a rolling upgrade strategy with minimal disruption.

On the host side, if a server requires more than two 2Gbps host bus adapters (HBAs) for availability, that number can be halved with 4Gbps. Fewer HBAs help lower the number of switch ports used and can help reduce overall cost.

The IBM DS4800 4Gbps SAN can impressively offer up to 1724MBps 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.

  4GBps FC interface technology
  
  The IBM System Storage DS4800 disk storage system supports a high-performance 4GBps FC interface. Increased host connectivity delivers the necessary bandwidth for high-throughput applications. Designed for data-intensive applications that demand increased connectivity, eight 4GBps 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 an FC storage area network (SAN).
