Advanced high-performance interface technology
The IBM System Storage DS4200 disk storage system supports a high-performance 4 Gbps
Fibre Channel interface. Increased host connectivity delivers the necessary
bandwidth for high throughput applications. Data-intensive applications that
demand increased connectivity are supported by four 4 Gbps host channels that
can provide up to 1550 MBps of sustained bandwidth, allowing for high throughput
applications through the four channels directly attached to the host servers or
connected to a Fibre Channel storage area network (SAN).
A lower total cost of ownership
Take advantage of high-performance with the DS4200 disk storage system. The
IBM DS4200 can offer up to 1550 MBps throughput with up to 121,500 IOPS
(input/output per second) from cache. 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 the minimum of two 2 Gbps host
bus adapters (HBAs) for availability to attain the required performance, then
that number can be halved with 4 Gbps. Fewer HBAs help lower the number of
switch ports used.
