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.
Have seen this myself on some HP kit (cant remember if it was broadcom
onboard or intel add-in pci-e cards that displayed the issues though)
I make almost exclusive use of Intel ET2 quad gigabit cards in my new
SAN (+iSCSI) + network stack and they have proven to be stable, fast and
solid.
know of others using Intel I340-T2 with no issue :-)
Thanks
With that being said, which NICs are you guys using in your setups?
Are you happy with them?

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
