This video demonstrates an upgrade of a VPLEX Metro Installation from GeoSynchrony 5.2 to 5.2 SP1. The VPLEX installation consists of one engine (two directors) and three backend storages (VMAX, VNX, CLARiiON) in each site.
VPLEX is used by a VMware vSphere 5.5 Metro Storage Cluster demo installation. The ESXi hosts (one in each site) are using Powerpath/VE to keep the IO local and still do load balancing.
