VMware Thin Disks on EMC Virtual Provisioning


Even before I left VMware for EMC I was being asked to comment on “thin on thin”: the use of VMware thin VMDKs on virtually/thin provisioned storage.  As a VMware employee I recommended VMware’s thin provisioning but referred to storage vendors for their own best practices.

Now, as a member of the storage vendor community, I will answer for EMC. I will do so with detailed text from an outstanding TechBook I recently discovered on EMC’s Powerlink.

Its guidance is clear and simple.

I have taken a long hiatus from blogging of late and am jumping back into the fold with a simple but important addition to the blogosphere. A few weeks ago Chad Sakac announced a new video showing the awesome vCenter plugin, the Virtual Storage Integrator (VSI). In this case the VSI was being used to demonstrate the capabilities of EMC’s new VNX array.

The VNX is awesome. The VSI is awesome. And the video is a potent demonstration of the combination of these two EMC products. But I firmly believe that most people consume internet content in 1-5 minute chunks. Weighing in at a hefty 16:50, I find this video a little cumbersome.

To that end, I broke up the video into a series of smaller parts and am presenting them here for anyone interested in these products.
