Video – #vSphere High Availability Enhancements: APD and PDL

With the growth in size and complexity of environments, the ability to prevent and recover from storage issues is more important than ever. HA now includes Virtual Machine Component Protection (VMCP), which provides enhanced protection from All Paths Down (APD) and Permanent Device Loss (PDL) conditions for block (FC, iSCSI, FCoE) and file storage (NFS).

Prior to vSphere 6.0, vSphere HA could not detect APD conditions and had limited ability to detect and remediate PDL conditions. When those conditions occurred, applications were impacted or unavailable longer and administrators had to help resolve the issue.

vSphere VMCP detects APD and PDL conditions on connected storage, generates vCenter alarms, and automatically restarts impacted virtual machines on fully functional hosts. By doing this, it greatly improves the availability of virtual machines and applications without requiring
more effort from administrators.
