ExpressCluster X

High Availability Software

Benefits

Product Overview

This system uses multiple servers: active

servers and standby servers. When any

failure occurs an active server, the jobs on

that server are quickly inherited to a standby

server to ensure that jobs continue running

with minimum downtime.

The client can continue

to access jobs without

awareness of the switch.

Maintenance

Business continuity is crucial in today’s increasingly comput-

erized business world. ExpressCluster X minimizes the loss

of business opportunities during maintenance or disasters.

The Operational status of even large-scale systems made up

of multiple clusters can be checked at a glance. Jobs can

also be moved to any server by performing simple operations.
