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.
With that being said, which NICs are you guys using in your setups? Are you happy with them? -M On Mon, Nov 26, 2012 at 12:04 PM, Lionel Sausin <[email protected]> wrote: > 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. > Lionel Sausin > > Le 25/11/2012 20:46, marcus a écrit : > > 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.
