NEC to promote its ExpressCluster X 3.0 Series

NEC Corporation is all set
to launch its global sales promotions for the “ExpressCluster X 3.0
Series” on October 1, 2010. 'ExpressCluster X' is the core of NEC's
ExpressCluster product line, which holds top share in the Asia
Pacific region's high availability software market. This software
enables the provision of highly reliable, low-cost systems by
observing system operations, detecting failures and automatically
transferring operations to a standby server that continues to carry
out application workload. This 'ExpressCluster X 3.0
Series' supports non-disruptive fail-over for virtual machines
through reinforced linking functions with virtualization software.
Moreover, the time required to initially synchronize data between the
active server and the standby server has been significantly reduced,
in addition to usability improvements in the graphical user interface
(GUI).

Some of the main features
of the software are as follows:

1) Supports non-disruptive
fail-over for virtualization systems:

Non-disruptive fail-over
for virtual machines is made possible through coordination with
virtualization software. Operations can quickly resume in the event
of a failure, thanks to the new ExpressCluster software, which
enables application workloads on virtual machines to restart activity
in the same position as just prior to a failure.

2) Accelerated data
synchronization:

Data synchronization has
been significantly accelerated between active servers and standby
servers during both a system's initial implementation and its
recovery from a failure. This new function, which synchronizes only
the actual data on a disk, can complete synchronization of a 1000 GB
disk in approximately 10 minutes from initial implementation.
Existing technologies require approximately 1,000 minutes to carry
out the same task.

3) Improved management
interface:

In terms of settings,
selections automatically appear on screen following the input of a
minimum amount of information by the user, which enable settings to
be easily selected during the system's initial implementation.
Furthermore, the management screen's graphic user interface (GUI)
has been improved for greater usability.
