Designing Availability In

Designing an HA service requires
assessing priorities to determine
which services must be highly
available. The business side
may consider all applications
to be critical. By understanding
the business and the impact
caused by an outage, the IT shop
can guide the business on HA

In a recent survey of systems administrators, Storix found that by the year
2015, more than 75 percent of all
their servers will be virtualized. On the
surface, it appears traditional disaster-recovery products will no longer
be necessary due to the capability to
snapshot virtual machines. It may not
be that simple. ...

Systems administrators typically just

Because VM snapshot backups are

left to store and manage large disk

Establishing Priorities

Two major areas are critical to
designing an HA service for any
company. You need the right
technology and you need to be
able to manage that technology
and the HA service. Technology
systems must be structured so that
any component can be removed at
any time without service impact.
