Direct back-to-back means a dedicated pair of NICs and a single cable
between them - this optimizes latency which DRBD is sensitive to.
DRBD is known to work on lesser configurations too, with varying
performance impacts.
The IP network should not matter as far as I know.

Hello
Thank you for making this product available!
In your documentation you say:
"It is recommended that you run your DRBD replication over a
"dedicated connection", preferably a "direct, back-to-back, Gigabit
Ethernet connection."
Does this mean a second NIC (in each host) on the same subnet,
a second NIC (in each host) on a different, separate switch and subnet,
or a second NIC (in each host) and a configured cross-over cable??
I am configuring 2 servers on a small network. One as primary and the
second as a hot standby. I want to use DRBD to replicate the data
partition.
thanks in advance
Marcus
