Hey, We are looking to replace our storage. Currently we use a 6 node Isilon cluster, but these may have to be re purposed. We use vSphere 5 for our less demanding servers and have around 70 machines...

I would suggest a NetApp solution, but I have no idea whether any would fit in your budget (not knowing british currency values). I am curious, though - why are you replacing the 6 node isilon solution...

View ArticleRe: Installing VSA on single node
So first off, you cannot install VSA on a single node and then add a second node. Similarly, you cannot grow a 2 node VSA to a 3 node VSA at this time. What you do however is what is termed a...
