The solution: IBM System Storage DS4700
Express
In a continuing effort to provide storage
solutions that are designed to provide
low total cost of ownership, high per-
formance, robust functionality, and
unparalleled ease of use, IBM offers the
IBM System Storage DS4700 Express.
As part of the DS4000 Series, the
DS4700 Express offers high-
performance 4 Gbps capable Fibre
Channel connections, up to 56TB of
physical storage capacity with
112 500GB SATA disk drives, and pow-
erful system management, data man-
agement and data protection features.
The DS4700 Express is designed to
expand from workgroup to
enterprise-wide capability with the
attachment of six DS4000 EXP810 disk
enclosures.
Helping to achieve a low Total Cost of
Ownership (TCO)
The IBM System Storage DS4700
Express Model supports a high-
performance 4 Gbps capable Fibre
Channel interface designed for data-
intensive applications that demand
increased connectivity. The DS4700
Express supports eight 4 Gbps capable
host channels that may be directly
attached to host servers or connected
to a Fibre Channel storage area net-
work (SAN). Four Gbps capable drives
and IT infrastructure are required to
achieve 4 Gbps capable throughput
speeds.
There are two ways to measure the
performance of a SAN device:
Megabytes per second (Mbps) and
input/output per second (IOPS). The
DS4700 Express 4 Gbps SAN solution
is designed to provide up to
1600 Mbps throughput (assuming a
4 Gbps capable system) with up to
125,000 IOPS. A 2 Gbps storage array
can require up to twice as many host
ports as a 4 Gbps array to deliver the
throughput of four 4 Gbps ports. The
DS4700 Express can help you free up
or eliminate the need for additional host
ports in the SAN for each array.
Not too big. Not too small.
