Lohit, good morning. I work for Dell in the EMEA HPC team. You make some interesting observations. Please ping me offline regarding Isilon. Regarding NFS we have a brand new Ready Architecture which uses Poweredge servers and ME series storage (*) It gets some pretty decent performance and I would honestly say that these days NFS is a perfectly good fit for small clusters - the clusters which are used by departments or small/medium sized engineering companies.
If you want to try out your particular workloads we have labs available. You then go on to talk about petabytes of data - that is the field where you have to look at scale out filesystems. (*) I cannot find this on public webpages yet, sorry On Sat, 18 Sept 2021 at 18:21, Lohit Valleru via Beowulf < beowulf@beowulf.org> wrote: > Hello Everyone, > > I am trying to find answers to an age old question of NFS vs Parallel file > systems.
