I don't have ISCSI setup done yet, i will give them a try if this would increase the performance.
Normally my goal was to have around 10-15 machines to run on this kind of Setup (NFS/2x1Gbit) - is this possible per design from a storage perspective??
I created the both NFS pools with each 4GB of cache-space, is this ok? (hole partition size is 900GB each).
