Datasheet

The DS4200 controller is a great
fit for both transaction-oriented and
bandwidth-intensive applications and is
designed to easily satisfy some of the
most performance-hungry workloads.
The combination of the DS4200
Express Model 7V and the EXP420 can
provide you with an affordable, high-
capacity, high-performance, SATA disk
only storage solution. This DS4000
series model is designed to provide an
economical alternative storage solution
that supports data archiving, reference
data, and near-line storage applications.
The DS4200 has four independent
4 Gbps FC host ports for direct-
attachment to host (FC-AL) or fabric
attachment to storage area networks
(FC-SW). Based on 4 Gbps FC tech-
nologies, the DS4200 is designed to
enable customers to prepare for the
future while fully utilizing their present
infrastructure. It is designed with the
ability to auto-negotiate FC connection
speeds, allowing it to integrate into an
existing 1 Gbps or 2 Gbps infrastruc-
ture, helping enable these environments
to immediately benefit while helping to
protect investment as the SANs transi-
tion to 4 Gbps.
The DS4200 storage system’s four
4 Gbps drive connections support up
to 112 disk drives with the attachment
of six DS4000 EXP420 storage expan-
sion units, making it a great choice for
performance-oriented or capacity-
oriented storage requirements. The sys-
tem is designed to support over 56TB
of Serial ATA (SATA) physical storage
capacity and 2GB of physical cache
memory (1GB per controller).
The DS4200 fits seamlessly into the
DS4000 Series. It runs the same
robust, yet intuitive, storage manage-
ment software—designed to allow
maximum utilization of your storage
capacity and complete control over
your rapidly growing storage
environment.
Wide range of storage consolidation and
clustering applications
The IBM System Storage DS4200 is
designed to be an affordable, scalable
storage server for storage consolidation
and clustering applications. Its modular
architecture—which includes Dynamic
Capacity Addition and Dynamic Volume
Expansion—can support highly variable
on demand business environments by
helping to enable storage to grow as
Information Lifecycle Management (ILM)
Information is the lifeblood of an
on demand business. With the DS4200
offering 4 Gbps technology, the
DS4000 Series can allow flexible
access and a broad range of scale and
performance options, providing struc-
ture and context to your enterprise
information. As a result, you have the
freedom to build data management
strategies that align with your evolving
information demands. The IBM DS4200
is designed to accommodate the
changing value of data over time while
maintaining data availability.
IBM System Storage DS4000
The IBM System Storage DS4000
Series is well known for its exceptional
performance, robust functionality and
unparalleled ease of use. Building on
this successful heritage, the new
DS4200 adds next-generation 4 Gbps
Fibre Channel (FC) technologies while
retaining compatibility with 1 Gbps and
2 Gbps infrastructure. The DS4000
Series proven storage technology is
designed to allow you to create a sys-
tem to handle some of the most
compute-intensive workloads and
provide robust functionality while main-
taining availability.
