  Description:

  In this radio show, Larry Karnis will be talking about how to deliver high service availability by eliminating or minimizing the causes of unplanned VM down time. Unplanned down time is caused by the failure of a server. By virtualizing workloads, we can minimize or eliminate unplanned VM down time by using VMware High Availability clusters to reassign VMs to new hosts and boot them up - automatically whenever a physical host fails. By employing VMware Fault Tolerence, we can eliminate unplanned down time completely. Fault Tolerence duplicates a running VM in real time. If the host running the Fault Tolerent VM fails, the duplicate FT VM is simply scheduled to run on a secondary ESX server. The cut over completes with no loss in service and no loss of I/Os or data.
