Storage Virtualization and WAN optimization help organizations achieve more stringent Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) without higher speed inter-site lines.
Although the consolidation from discrete physical servers to virtual servers has made it possible for many organizations to configure an affordable remote Disaster Recovery (DR) site, the inter-site traffic to keep the DR location current soon grows to be a problem. The volume of updates from newly created virtual machines at the primary site can rapidly climb to the point where they exceed the line’s capacity to transmit them. The overload causes the DR site to fall behind more and more, exposing companies to unacceptable data loss in the event of a disaster.
Some customers’ first thoughts were to upgrade to higher speed lines. However, after seeing how much more that would cost in infrastructure and recurring leased line rentals, there is often the need to investigate other less pricey alternatives to attain a satisfactory Recovery Point Objective (RPO).
In this case study, the IT consultants at W@terstons pondered the scenario and proposed to address these requirements through a clever combination of storage virtualization and WAN optimization.
