NEC S-Series Storage meets the most
advanced requirements for data storage
from small to large enterprises.
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 requirement, 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

High-end model
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.

Excellent Management and Operational Functions
■ 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.
■ 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.

■ 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.

■ 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
