SRM Folder Mapping

introduction
In this article  we are going to discuss about SRM Folder mapping.  In  most vSphere environments:>  Virtual machines and data centers organized into folders in vCenter server.  In real production environment, There are thousands of virtual machines running in your production vCenter server.  Without SRM folder mapping, all your virtual machines wilRead More…

SRM Create Resource Mapping

introduction
In these articles, we are going to discuss about Site Recovery Manager inventory mappings. Basically inventory mappings involves in mapping the resources (clusters and resource pools), folders, and networks of the Protected Site to the Recovery Site. Why we need resources mapping
  Resource mapping  is required because we have  2 different vCenter servers installRead More…
