Chad – you know he’s isn’t a virtual geek – he’s a real geek – nothing virtual about that! As an EMC-er Chad has been excellent in releasing docs on EMC issues generally and stuff on the whole VCE thang.
First up is a blog post which is as fresh as a daisy – from yesterday. It’s about FAST from EMC (yes, now one every comes up with acryonms that are S.L.O.W do they). What is FAST – well, its Storage VMotion done within the array between tiers of storage to improve performance. Think of it as DRS for storage. To learn more visit:
Chad has some interesting clarification about vBlocks and some stuff on ionix as well
Finally, Chad has flagged up two very important bugs and their work arounds. The first is about a performance dip when using the built-in multipath policy of “Round Robin” in vSphere4
and the second is this one – which concerns what happens if you just de-present a LUN without first doing the correct steps in vSphere first. Personally, I wouldn’t call this a bug per se – just unexpected behaviour when an admin does something without engaging brain first – hopefully the best practise is something folks do as naturally!
