Emergence of new technology often brings with it new solutions that take advantage of the capabilities in interesting ways to solve problems for businesses. I’ve recently been speaking with ClearSky and Xtium about an emerging model for storage they are bringing to the market.
With Virtual Volumes as a fundamental building block of their solution, it is my pleasure to provide a guest-authored post from two leaders of these companies, Laz Vekiarides and Tim Vogel. Here they will expand on how their offering helps companies achieve all the benefits of per-VM control and management while preserving performance and availability coupled with the resilience, scale and economics of cloud storage.

It’s been several years since the first virtual volumes (VVol) demonstrations at VMworld 2012, and it’s extremely exciting to see the technology go live this year. To us in the storage industry, VVol represented the most elegant solution to one of the biggest administrative problems that exist in virtual infrastructure: the mapping between virtual machines and their underlying storage. Up until now, storage management in virtual infrastructure has been very LUN-centric – particularly for things like snapshots, clones, and data protection. To an administrator who is supporting workloads and VM’s, this adds another layer of unwanted complexity. Rather than being able to focus on the needs of the individual workloads, they have to worry about the characteristics of this shared storage resource. Is it overloaded? Is a single “bad” VM making life worse for everything else? Is there enough free space? How to split things up if another LUN is added? In my previous life, I would spend untold hours and resources helping customers deal with these intractable issues. In fact, some of the biggest barriers to building a true self-service private cloud experience have centered around these storage problems.
