Avoiding a Disastrous Disaster Recovery with VMware vSAN
One of the most vital roles and characteristics of effective data storage is the role backups play if a higher education institution suffers a disaster. Universities have always embraced continuity of operations planning, and protecting data storage has always been a part of that. Any good COOP plan will have a storage component. Thankfully, VMware vSAN integrates disaster recovery into its main platform.
Managed as a core component of a vSphere environment, vSAN is built on an optimized input-output data path in the vSphere hypervisor for exceptional performance. This means that separate administration tools and connections are not required, thereby simplifying management, particularly in locations that have little or no local IT staff, such as a disaster recovery site.
Additionally, features like VMware vSphere Replication provide asynchronous virtual machine replication with recovery point objectives configured per each virtual machine. This enables precise control over which workloads are protected in time increments as short as five minutes. Replication also avoids the need to provide excess capacity at a disaster recovery site to accommodate an all-or-nothing replication approach. Simply set important data to be updated and waiting should disaster strike.
With solutions like vSAN, universities of all sizes can benefit from reliable COOP backup and planning no matter what happens to the production environment. This will help ensure that higher education institutions are back up and running quickly during any crisis.
