NAS Isn’t Good at Highly Concurrent Access Locking Engines Not Designed For Massive Parallelism Locking Is Often File Level, Not Granular NAS is Point to Point Technology One Server One client If your server isn’t big enough – then your storage isn’t fast enough. Some NAS systems forward requests – but multi hop doesn’t scale well. NAS Protocols can’t support RDMA Access No Support For Native InfiniBand, the leading HPC protocol. Parallel File Systems Are Designed By HPC Engineers & For HPC Research
