With a 53% share of the virtualization market, VMware is hot. For IT managers looking to squeeze the most out of racks of servers, it’s the solution of choice.

VMware includes features to boost availability, but a complete high availability/disaster recovery solution requires more. That’s why Symantec offers two new versions of Veritas Cluster Server designed specifically for VMware environments. They address three key issues: unplanned downtime, deep monitoring, and disaster recovery.

Unplanned downtime

VMware VMotion technology makes it easy to move running virtual machines from one physical server to another. That’s helpful for planned downtime such as powering down a server to install a memory upgrade. But for unexpected events—an operating system crash, for example—VMotion can’t initiate an automatic failover, and won’t prevent unplanned downtime Give that problem to Veritas Cluster Server for VMware ESX. It monitors each physical server and can automatically fail over to another if needed, avoiding downtime.

Deep Monitoring

With dozens of applications running on the same physical machine, failures are more granular: A virtual machine can fail even if the physical server is still running. External events—network outages, storage bottlenecks—can also take down one or several applications. Veritas Cluster Server for VMware ESX monitors not just physical servers, but also virtual machines, applications, storage systems, and network components. It catches failures at any point—and takes corrective action to keep critical applications available.

Disaster Recovery

VMware HA, the company’s high availability solution, is a good first line of defense for virtualized environments. However, it can’t defend against a disaster that throws an entire data center offline. Veritas Cluster Server for VMware HA can. This global clustering solution can fail an entire VMware environment to a disaster recovery site.

Veritas Cluster Server for VMware HA provides an extra layer of resilience that can spell the difference between business continuity—and being out of business.
