Solution Scope

Building an effective disaster tolerant solution can often be a very complex and time consuming task.

Furthermore most disaster tolerant solutions, implemented at customer sites, are often untested and may fail

to protect customers when failure occurs. Depending on the data center solution or application, the recovery

point objective and recovery time objective may differ from customer to customer. Any disaster tolerant

solution must be able to accommodate both planned and unplanned downtime.

Planned downtime

Planned downtime is a result of equipment of software maintenance that is disruptive to system operation

and usually cannot be avoided with a currently installed system design. In general, planned downtime is the

result of some logical, management-initiated event.

Unplanned downtime

Unplanned downtime results from a natural disaster, environmental anomaly or sudden hardware or

software failure and may impact an entire site. HP StorageWorks Continuous Access EVA and VMware

vCenter Site Recovery Manager offer an ideal solution, allowing you to move your data and secure your

mission critical applications to a safe offsite data center, away from harm.

This case study demonstrates a disaster-tolerant solution between two data centers in a campus or

metropolitan area. In this scenario, the data centers are merged through a shared dual redundant storage

area network (SAN) (see Figure 1). EVA 1 and EVA 2 are connected through the shared SAN and data

replicated synchronously with Continuous Access.
