> Can someone either let me know what the max NFS thread count is for Isilon either per node or cluster or let me know where I can find this information? I have a customer running into perf issues with an NS due to the 256 thread-count limit and want to know if Isilon would fix this.  From the  White Paper    NEXT-GENERATION GENOME SEQUENCING USING EMC ISILON SCALE-OUT NAS: SIZING AND PERFORMANCE GUIDELINES   July 2013       On page 18:  NFS number of threads: This is the number of NFS server daemon threads that are started when the system boots. The OneFS NFS server usually has 16 threads as its default setting; this value can be changed via the Command Line Interface (CLI):  isi_sysctl_cluster sysctl vfs.nfsrv.rpc.[minthreads,maxthreads]  Increasing the number of NFS daemon threads improves response minimally; the maximum number of NFS threads needs to be limited to 64.   (quote end)   I think that's 64 per node (isi_sysctl_cluster just spreads the setting to all nodes.) And wether 64 Isilon threads do better or worse than 256 "brand X" threads is up to the implementations; you might need to do tests.  -- Peter
Hello,  Can someone either let me know what the max NFS thread count is for Isilon either per node or cluster or let me know where I can find this information? I have a customer running into perf issues with an NS due to the 256 thread-count limit and want to know if Isilon would fix this.  Also what is the smallest file size that can be striped? I know Isilon writes in 8K blocks but what is the file size below which writes are mirrored for protection instead of striped?
