Have anyone done any benchmarking as to what is the optimal choice for the OSS? We plan to deploy a small lustre setup with two OSSs with dual FC to two raids and infiniband to the clients. We plan to by HP Proliants for this task and have the choice between EM64T and Opterons, do the increased memory bandwidth of the Opterons have anything to say in this matter or will the higher clock frequency of the EM64Ts be beneficial? We plan to run the servers as combined MDS/OSS with failover. I see from the faq page that you have achieved 550MB/s on Opterons. Do anyone have numbers for EM64T?
