Hi Gary,
We don't use NFS for our TSM servers, but we have been struggling with NFS
over 10GbE in other areas. While not a universal solution, we've gotten
significant performance improvements by disabling the following NIC offload
options:
gro
lro
rxvlan
txvlan
rxhash
For instance, you can disa
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 you

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

Because the more I can keep on disk the less that goes to tape - another
constrained resource. We have 7-TSM servers sharing 9-3592 tape dr

SO sorry, my original TSM reference was a hair stale -- try this one:

I understand you have constraints, so I am not telling you to do something
you cannot do.
What I am saying is - yo
I understand and we have been using ext4 since it was available. All of my
stgpools are ext4. The DB filesystem is ext3 per the requirements in the
document you referenced for setting up TSM on Linux.
However, they are spread across 2-ext4 filesystems due to the 16TB limit
for ext4.
Are you say
