As a best practice, most companies conduct periodic disaster recovery tests to demonstrate compliance with corporate policy. Compliance tests can be both operationally expensive (tying up critical resource for the duration of the test) and cause business impact. Many companies simply cannot afford to have the IT operations unavailable for an extended DR test and therefore implement a cluster to simplify and shorten the test. Our G/S team has expertise in DA/HR and can help you develop a plan for test your system or can work closely with your team to do the test on a calendar schedule of your chose.
