Some tests results: lustrefs over nfs on VM
Hi, in our environment we got pretty good io performance on VM, with following configuration: lustrebox: /lust mounted on "GATEWAY" over IB GATEWAY: export /lust as nfs4 on 10G interface VM(test.vm): import as NFS over 10G interface [root@test.vm <root@gans.vm> ~]# dd if=/dev/zero bs=128K count=100000 of=/test/tmp/test.tmp 100000+0 records in 100000+0 records out 13107200000 bytes (13 GB) copied, 20.8402 s, 629 MB/s looks promising for the future deployments. only one problem remains that on heavy io I get some wornings that the vm network is saturated, are there way to configure the bandwidth limits to 10G for the VM Interface?? thank you beforehand, Arman.

[root@test.vm <root@gans.vm> ~]# dd if=/dev/zero bs=128K count=100000
Without oflag=direct, you are hitting (somewhat) the cache.
of=/test/tmp/test.tmp 100000+0 records in 100000+0 records out 13107200000 <(310)%20720-0000> bytes (13 GB) copied, 20.8402 s, 629 MB/s looks promising for the future deployments.
Very - what's the backend storage?

Yes, but you really need a dedicated storage interface, no? Y.
thank you beforehand, Arman.
