As part of last week’s Storage Field Day event, at the Solid State Storage Symposium I moderated a panel entitled “Solid State – Simply a big cache or a real storage tier?” The full brief was as follows:
Solid state disks blur the boundary between cache and storage, with a foot in both camps. Can solid state drives really be treated as a new tier of storage or simply as a way to add more performance enhancing cache to existing arrays? This panel will discuss whether data should permanently reside on solid state media or whether the optimum and most cost effective solution is to simply use SSD to hold the working set of data in the array.
I was lucky to have some great panelists and the discussion is both technical and philosophical in nature as to how SSDs should be used when building storage arrays.
The video is embedded below and well worth watching.
