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.
