I am considering deploying a SAN but I have found contradictory information.
The thing is that I would like my cluster nodes to be able to read the same data from a unique source (I have a configuration file hierarchy where cluster nodes come to fetch the data they need for their computation). I thought a SAN would do the trick (a NAS may be a bottleneck). SAN over ICSI with a dedicated network for data sharing. (I was thinking about Dell EqualLogic Product).
However, it seems that the SAN could not be shared unless I deploy a clustered file system (like GFS). Am I correct? And is this coherent with the kind of usage I want ?
I was incapable of understanding whether FluidFs was a clustered file system. They kind of mix SAN and NAS in a way I do not really understand.
