Strange
Neither VMware's vSAN or EMC's ScaleIO are mentioned in this article. Does El Reg really have that big of a beef with Software Defined Storage or is it just bias against Virtzilla and EMC? vSAN is the fastest growing hyperconverged/SDS product out of all competitors yet doesn't even rate a mention in the article. I find that rather strange.
Transparency: I'm a Senior Systems Engineer in SDS for VMware.
