I've searched quite a bit and can't seem to find any guidelines on the
following:

1) VMWare VSwitch configuration to maximize throughput for VM
backups/restores
2) Expected throughput using 10Gb adapters

We are in a situation at the moment where mass backups work quite well and
are very fast: as fast as the TSM server can handle.  However, individual
restores/backups are quite slow.  We've tested on a VMWare cluster with
1Gbps NICs attached to the management network and with 10Gbps attached to
the management network.  Both scenarios are quite a bit slower than I'd
expect.  Average backup/restore transfer rates are in the 25 MB/s range
using 1Gb NICs and around 55 MB/s using 10Gb NICs.

How do I improve the throughput on these single-VM backup and restore
sessions?

Thanks!
