Datasheet
Using its ability to auto-negotiate FC
connection speeds allows you to inte-
grate it into an existing 1 Gbps or
2 Gbps infrastructure.
The DS4700 Express storage system’s
four 4 Gbps drive connections are
designed to support up to 112 disk
drives with the attachment of six
DS4000 EXP810 disk enclosures. This
makes the DS4700 Express a good
choice for performance-oriented or
capacity-oriented storage requirements.
Models 70 and 72 are designed to sup-
port over 33.6TB of Fibre Channel
physical storage capacity.
The DS4700 Express expands the
DS4000’s history of flexibility with
another configuration option—cache
size. The DS4700 Express is available
in two models: Model 70 is designed to
support up to 2GB of physical cache
memory (1GB per controller) and the
Model 72 can support up to 4GB of
physical cache memory (2GB per
controller).
The DS4700 Express is integrated into
DS4000 Series environments, running
the same robust, yet intuitive, storage
management software as the other
DS4000 Series models. It is designed
to support high utilization of storage
capacity and control over your rapidly
growing storage environment.
Serving a wide range of storage
consolidation and clustering applications
The IBM System Storage DS4700
Express is designed to be an afford-
able, scalable storage server for stor-
age consolidation and clustering
applications. Its modular architecture,
which includes Dynamic Capacity
Addition and Dynamic Volume
Expansion, can support on demand
business environments by helping to
enable storage to grow as demands
increase. Autonomic features such as
online firmware upgrades and DS4000
Service Alert also are designed to help
enhance the system’s usability.
Helping to increase performance
The DS4700 Express is designed to
manage some of your most
compute-intensive workloads. Excelling
at IOPS and Mbps, the DS4700
Express works well for both
transaction-oriented and bandwidth-
intensive applications. Additionally, the
DS4700 Express is a good choice for
environments with intense replication
requirements, because its extra “horse-
power” is designed to efficiently handle
the additional performance demands of
FlashCopy, Volume Copy and
Enhanced Remote Mirroring.
The DS4700 Express Model 72 has
eight independent 4 Gbps Fibre
Channel host ports for direct attach-
ment to host (FC-AL) or for fabric
attachment to storage area networks
(FC-SW). As one of the industry’s first
enterprise-class storage systems using
4 Gbps Fibre Channel technology, the
DS4700 Express is designed to enable
you to prepare for the future while fully
utilizing your present infrastructure.
