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)<br>
<br>
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.<br>
<br>
know of others using Intel I340-T2 with no issue :-)<br>
<br>
Thanks<br>

setups? Are you happy with them?</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>

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>
Marcus <br>
