***NEC Delivers New Disaster Recovery Solution; Solution Provides
Customers with Rapidly Deployed, Cost-Effective Infrastructure
for Mission-Critical Resources

ClusterWorld Expo
Santa Clara, California
April 06, 2004

NEC Solutions (America), Inc., a premier provider of integrated
solutions for the Connected Enterprise in North America, today
introduced the NEC Disaster Recovery Fault Tolerant (FT)
Solution, a highly anticipated new enterprise-grade disaster
recovery solution that allows companies to recover from virtually
any infrastructure system failure while ensuring the ongoing
availability and integrity of mission-critical resources. NEC
unveiled its Disaster Recovery FT Solution today as part of its
participation in the ClusterWorld(TM) Conference and Expo in San
Jose, Calif.

Built with NEC's EXPRESSCLUSTER(R) software, Express5800/320Lb
server and S1300 storage platforms, the Disaster Recovery FT
Solution offers customers an easy-to-deploy, cost-effective
infrastructure solution that protects mission-critical data in
the event of the destruction of local computing resources, while
allowing surviving resources to continue working with access to
the latest data.

According to NEC, the primary objective of a disaster recovery
plan is to enable an organization to survive a computer room
disaster and to re-establish normal business operations in just a
few minutes. In order to survive, an organization must ensure
that critical operations can resume within a reasonable
timeframe. NEC's Disaster Recovery FT Solution is designed to
minimize the duration of a serious disruption to business
operations, facilitate effective coordination of recovery tasks,
and most important, reduce the complexity of the recovery effort.

NEC's Disaster Recovery FT Solution is a comprehensive solution
that leverages several leading technologies developed by NEC to
provide the following benefits:

-- Up to 99.999% Hardware Availability - Server and storage
technology minimizes chances of remote failover operations that
require service interruptions, failover and fail back operational
risks.

-- Automatic Failover via WAN - Seamless operations between fault
tolerant procedures in local failures and disaster recovery
procedures.

-- Disaster Recovery in Minutes - Node heartbeat monitoring
detects whether a cluster node is functional, and then enables to
failover within minutes.

-- Data Integrity - Application data mirroring technology
provides complete data integrity between production local
database and remote one.

-- One-Stop Support - NEC Solutions America provides total
solution support including hardware, software and services.

-- High Performance Storage - Fault tolerant S1300 storage from
NEC complements the fault tolerant servers with fully redundant
hardware providing nearly 4TB of fibre channel storage capacity.

-- Cost-Effective Configurations - Customers can choose from
"Active/Active" configurations where both servers host and backup
data or "Active/Passive" configuration where active applications
reside on one server and data is backed up to another server for
emergency use.

Scalable Software, Continuous Hardware

At the core of NEC's Disaster Recovery FT Solution is a scalable
and flexible clustering software solution that provides automatic
recovery. When a fault occurs at the server, the software
understands that the server is designed with fault tolerant
hardware. However, in the event of a data center-level disaster
that destroys the whole server, the EXPRESSCLUSTER software
automatically detects the loss of the server and instantly
instructs another server to take over the workload of the faulty
server, allowing the users to access all their applications and
data to continue to operate. Using virtual IP addresses and
virtual computer names enables a server to be reconnected without
renaming of the devices or the client application being aware
that the server was switched.

The power behind NEC's Disaster Recovery FT Solution is the
Express 5800/320Lb server which is designed to provide mission-
critical applications with continuous availability in an easy to
manage, affordable, compact, rack-mount (4U) or pedestal
platform. The Dual Modular Redundant (DMR) design of the
Express5800/320Lb allows easy replacement of major subsystems
without interruption of processing. The unique dual-modular
hardware architecture is comprised of redundant subsystems
executing all processing in lockstep to virtually eliminate any
single point of failure while safeguarding data integrity. These
CPU subsystems perform the same instructions at the same time,
with instantaneous failover to the redundant subsystem in the
event of hardware failure.

For example, if a disaster error occurs, the system isolates the
faulty subsystem and instantly fails over to the alternate
subsystem without memory data loss or application interruption.
Servicing the system is as simple as replacing the faulty module
while the server remains online. There is no interruption in
processing, no data loss and no performance impact.
