Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


Hi all, we have been testing drbd using connect/disconnect on wan links to
get daily/weekly type offsite replication. That seems to be working pretty
well and we are happy with that. I have received approval to get a 10mb pipe
between my office and our co-location facility to go with real time. Im
testing it with vmware6 where I can limit the bandwidth between devices, but
of course the latency is about 2ms not 40-50ms that would be over a 10mb
pipe. We only have about 1TB of storage and a couple hundred users with an
exchange server database.  Im thinking the 10mb pipe will be enough  but of
course I need a 3 yr contract to get one installed so would like to get some
opinions on how I could better test the scenario.
