Hi, I''ve been experimenting with Lustre and have got some decent results from it compared to NFS. So a question to all the storage experts out there is, what would you recommend for this installation. We have a 21 node cluster, one head node and 20 cluster members. At the moment data being processed on the cluster is copied locally to each individual cluster member. This is fine, but the data is getting larger all the time and at some point this will no longer be feasible. In an ideal scenario I would like to have a shared storage configuration where all 20 members can access the data at the same time. In a Lustre setup, how would you approach this. To give you an idea of transfer rates etc. Writing and reading a 1gb file 1Gb write locally - 5 seconds 196 Mb/s transfer rate 1Gb read locally - 3 seconds 340 Mb/s transfer rate For 10 members of the cluster using the same OST at the same time ( but different files ) 1Gb write - 2mins 30secs 7.1 Mb/s transfer rate 1Gb read - 3mins 8secs 5.7 Mb/s transfer rate Don''t get me wrong this is nearly double the performance on NFS For 10 members using the same NFS share ( again different files ) 1Gb write - 3mins 56secs 4.5 Mb/s transfer rate 1Gb read - 8mins 24secs 2.1 Mb/s transfer rate Thanks Iain _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ SCRI, Invergowrie, Dundee, DD2 5DA.
