Hi Gary What performance does Iperf3 get when you run it on your NFS server?
There is a lot that is going on that has very much to do with your disk configuration on both your TSM server and the NFS server. Have you looked at a tool like iometer to see what performance you can squeeze out of your storage subsystems? Have you seen this? http://www-01.ibm.com/support/docview.wss?uid=swg21470193 Best regards, Mike Ryder RMD IT Client Services On Tue, Feb 2, 2016 at 12:54 PM, Lee, Gary <g...@bsu.edu> wrote: > Tsm server 6.4.3, > RHEL 6.7 > 4 Dual-Core AMD Opteron(tm) Processor 8220 SE CPUs > 128 gB memory > > I recently installed an intel 10 gB Ethernet card. > Iperf3 test shown below gives around 7 gb throughput. > However, when running multiple migration and reclamation processes, and > watching network traffic through an independent tool, I cannot get over the > 900 mb/s threshold. > > The tsm storage pools are on a file system mounted as follows: > > Nxback-Pool02.servers.bsu.edu:/volumes/Pool02/TSMBackup/tsm02 > /tsminst1/storage nfs > rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys > 0 0 > > I am running out of options. > > I don't expect to see the full throughput, as disk speeds will have a good > deal of impact. > > Any ideas would be helpful. > >
