VMware Infrastructure enables improved availability in the datacenter through the following availability features:
VMotion – Live migration of online virtual machines from one physical server to another. Regular maintenance of physical servers no longer requires any scheduled downtime with VMware VMotion.
HA – Cost effective, low complexity, automated failover of virtual machines in case of physical hardware failure to other servers in a cluster.
Storage VMotion – Live migration of online virtual machines from one physical array to another. With this feature, scheduled downtime is no longer required to perform regular maintenance on your storage array or to migrate data from one array to another.
