NEC S-Series Storage
S4900 / S2900 / S2500 / S1500

The growing volume of data has a tremendous impact
on all facets of a business from the enterprise to the
workgroup. That is why it is essential to have storage
products that increase data efficiency, provide full
availability and allow the business to realize an
extremely low cost of ownership. To meet this require-
ment, NEC provides a full range of storage products
— from the NEC Storage S4900, which is a high end
storage system with advanced crossbar technology to
an entry-level model that is very cost-effective. These
products provide for high-performance and function
including 4Gbps FC host interface and low cost
backup/archive with mixture of high-perfor-mance FC
and low cost SATA disk drives*1. These functions are
maintained by a very functional series of NEC storage
management and control software. NEC S-Series
Storage opens the path to a new IT environment.

■ Ultra high-performance
with ultra high availability
Using ultra high speed cross bar technology connecting cache
function and node function the NEC S Series storage provides
for end-to-end performance and availability. The S4900 has a
bandwidth of 192GB/s which allows for high-speed access to
data even with many servers attached. Redundancy provides for
full data availability even in the event of a component failure.
■ Cache redundancy
prevents response degradation
The cache for the S4900 has two sets of mirrored cache. The
redundancy permits cache writes even in the event of a cache
failure. This provides for safe and high-speed response.
vin the case of S4900
■ Equipped with 4Gbps FC host interface
Maximum bandwidth of 400MB/s with 4Gbps FC host interface
allows high speed response even with many servers connected.
■ RAID 6 substantially increases availability
As the capacity of disk drives increase, it takes substantially
longer to re-build data in the event of a disk drive failure. Using
RAID 6, which utilizes dual parity, this is minimized and can
also accommodate two drive failures without any loss of data
availability.
■ Virtual capacity management
The Dynamic Pool function allows LUN capacity to be expanded
or reduced in a RAID 6 environment without disruption to the
application. *1: Expansion by 6 or 10 HDDs for S4900

■ Phoenix technology to prevent
business operations being interrupted
This technology first isolates the disk drive where a response
delay has occurred, and automatically checks this isolated
disk drive. If no problem is found, the isolated disk is restored
to the original RAID configuration, minimizing the chance of
switching to the hot spare disk. This technology also minimizes
the delay in accessing from a server, because a disk drive where
a response delay occurs is isolated temporarily, and other disk
data in the RAID is used to continue processing.
■ Replication functions
NEC S Series storage can satisfy a variety of needs including
high-speed disk backup as well as low-cost backup with its full
suite of replication functions.
■ Low-cost backup/archive by
mixture of FC/SATA disk drives
S2900/S2500/S1500 supports large capacity, low cost SATA
disk drives as well as FC disk drives. FC disk drives for core
business operations which require non-stop operation and high
performance, and SATA disk drives for backup which requires
large capacity and low cost. Both kinds of disk drives can be
installed in a single disk array unit.
■ Security access control
Access to individual logical disks can be controlled. Write
access can be restricted from any server providing for complete
security and integrity of data.

STORAGE SOFTWARE
As IT systems store more and more data every year, it is
becoming more important to operate and manage data
efficiently. Storage Management Software provides a group of
integrated operation management products to perform total
management of storage systems. It provides more efficient
storage operation management by supporting management
tasks including fault and performance monitoring and making
backups in a unified way, decreasing the TCO (Total Cost of
Ownership).
Storage Management
Device Management
The NEC Storage Manager keeps track of the status,
configuration, and conditions of the disk arrays. These functions
are tightly integrated with operation management software,
making total system management possible.
Performance Management
Storage Management Software provides management
information about the performance and capacity of disk arrays,
making efficient storage management possible.

Building an IT system where a diverse range of business
activities are carried out requires the efficient use of data and a
system with high availability. Storage Control Software provides
the basic system functions to ensure that the system is highly
available and operable, with a data protection function with no
influence on online operations, a disaster recovery function,
autonomous resource management, and the efficient use of
resources.
Replication
Storage Control Software provides functions for protecting data
and improving the operability of data without affecting online
operations by duplicating volumes in the storage system.
Storage Control
Disaster Recovery
Storage Control Software provides the function to implement
disaster recovery by providing the basic functions for disaster
control solutions.
Resource Control
Storage Control Software provides functions which
autonomously adjust resources, by eliminating bottlenecks and
setting access controls, so that resources can be used safely
and efficiently.
High Availability
Storage Control Software has a path switching function to
provide for high availability.
