#56 – Defining Scale-out Storage

This week’s podcast is a conversation between Martin and Chris, talking about how we define scale-up and scale-out storage.  A recent discussion on Twitter about Pure1 and the idea of federated scale-out generated some interesting feedback, so we thought it might be good to get some definitions in place.

The opening discussion talks about how scale-up and scale-out should be defined and what definitions of scale-out exist.  Volume managers used to be the old-school way of implementing federation, as was storage virtualisation.  So perhaps federation is a genuine use case.

Martin and Chris move to talk about NAS and object, then reflect on how the cloud computing providers implement their storage platforms.  Surely these are scale-out?  The truth is, that level of detail is generally kept secret.  Finally, the conversation talks about one of the biggest storage headaches – rebalancing.
