PowerCLI: Add & remove VMs from DRS Groups based on datastore location

Lately I have been working on a number of virtualization projects which make use of VMware vSphere Metro Storage Clusters (vMSC). With most of these types of implementations, virtual machines must be pinned to a preferred site to minimise impact to virtual machines in the event of a site failure. DRS groups are the most common way to achieve this, however I was wanting to find a way to automate the add/remove of virtual machines based on each VM’s datastore location.

To begin, I configured each of the datastores with a prefix of the site which was its preferred site, e.g. DC1-VMFS-01 or DC2-VMFS-01. I then placed VMs on a datastore which corresponded to their preferred site.

With the help of DRSRule I was then able to create two PowerCLI functions to automate the process to add the VMs to a corresponding DRS VM group based on their datastore location. The function can be used with a datastore name, prefix or suffix.

EMC VPLEX Virtual Edition – Part 1 – Prerequisites

In this series I will provide an insight into a recent deployment I performed of EMC VPLEX Virtual Edition 2.1 SP1 (VPLEX/VE).

For those who are not familiar with the product, VPLEX/VE is a virtual storage platform which provides storage capabilities for Active-Active datacentres for VMware vSphere stretched clusters. The vSphere stretched cluster is configured with compute, network and storage at two physical sites. EMC VPLEX/VE together with the vSphere stretched cluster resources provide the functional requirements to run virtual machines from either datacentre, as well as the ability to move VMs between sites using vMotion and Storage vMotion.
