Hi, when I ndmpcopy from say, volA to volB on the same head does ndmpcopy use the loopback to do this ?
If so, at what speed can the loopback run at ? I can not seem to go faster then about 20 GB/hr (about 50 Mbits/sec).
I do have GigE NICs in the filer for regular nfs connections to clients.
Remember that when you are ndmpcopying on the same head that the one head has to do both the dump and the restore, so it takes more CPU. Perhaps you are CPU limited. Verify with sysstat.
