Pauli is on a distinguished road
Does anyone run a compute cluster with diskless compute nodes?

We are considering a proposal for a compute cluster which has diskless compute nodes. An external to the cluster high speed SAN would provide scratch space and possibly OS file storage. The SAN would be connected to the compute cluster using Infiniband.

The compute cluster will be used for both FEA and CFD analysis.

Would the performance of such a system match/exceed a similar set of hardware which uses traditional local scratch space?

What about having Raid 0 arrays in the compute nodes?
