I'd just like to note that we've had some trouble with certain NICs in which the adapter resets itself. In this situation, funny things can happen with DRBD depending on how you are set up. A switch in the middle keeps the link active on both nodes and can be used to prevent such a situation.<div>

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

<br>
Thank you for making this product available!
<br>
<br>
In your documentation you say:
<br>
"It is recommended that you run your DRBD replication over a
"dedicated connection", preferably a "direct, back-to-back,
Gigabit Ethernet connection."
<br>
<br>
Does this mean a second NIC (in each host) on the same subnet,
<br>
a second NIC (in each host) on a different, separate switch and
subnet,
<br>
or a second NIC (in each host) and a configured cross-over
cable??
<br>
<br>
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.
<br>
<br>
thanks in advance
<br>
