BE2012 restore of VM (vmware) through 10gbps nic
Our site has a vsphere 5.1 infrastructure and backup VMs wit the SAN transport. Jobs are ok with good performances.
However, SAN transport isn't available for restores. So we use a 10gbps link : the BE 2012 sp2 server has a 10gbps nic, and the ESXi's in the vsphere cluster too.
When i try to restore VMs I get a maximum bandwidth of about 850mbps (just as if we had a 1gbps nic).
On the BE server and the ESXi the uplink is well seen as 10gbps full duplex.
If I try to copy a large file from my BE server to a windows VM I get a throughput of about 5gbps which is normal. So I think the network is not the problem.
Is there a limit in BE 2012 which prevents from using a 10gbps bandwidth ?
Have people here already used BE 2012 to backup and restore VMs with a 10gbps NIC and what were the results in terms of performance ?
Thanks a lot.
