The purpose of this operation was to encapsulate existing datastores into VPLEX to take benefit of the synchronous and high availability features of VPLEX Metro between 2 sites.
Unfortunately I got into trouble with an issue that I really didn’t expect and anticipate. This is why I thought important to give you my experience on this and hopefully help anyone planning to do the same. But before going any further, let me give you some info regarding the customer environement and VPLEX.
VPLEX is a virtual storage system that stands between your storage arrays and your hosts. It virtualizes all arrays connected to it and then presents as one storage system your volumes to hosts.
So basically, you attach any compatible storage to VPLEX and then the magic goes, all your hosts will see just one array with the volumes you’d like to present. I won’t go into details on how to configure VPLEX as this is out of scope in this article.
One of the strength of VPLEX is that it’s a great storage system and perhaps the best allowing to have a real active-active infrastructure and migrate VMs easyly between multiple sites. But is good also for migration of multiple storage arrays.Continue reading
