Bond on proxmox

[frankz]

Hello everyone, I would like to create a link aggregator to have 2 GBit of network. Do I need the switch to provide for lacp or can it be done regardless?

You can use modes 0,2 and in some cases 3,5,6 to try to achieve your goal. Whether you will, depends on many other environmental variables and finer details of your bond configuration.

Thank's

Also keep in mind that with most bond types you won't get 2 Gbit for a single connection. Its just 2 Gbit throughput, so you can use 2x 1Gbit connections in parallel.

However if you actually wanted to enable the link aggregator you need 802.3ad on the swtich, at least that's what server to increase bandwidth

Even with 802.3ad you are limited to two 1Gbit connections and not a single 2Gbit connection. If two hosts can communicate with 2Gbit depends on the software and also the hashing. With layer2+3 two hosts can only communicate using 1Gbit because its one connection per IP. With layer3+4 its one connection per IP+port. So two hosts could communicate with 2 Gbit in case the application is able split the communication in two streams and send the streams over different ports. Then its still 2x 1Gbit but atleast 2x 1Gbit between two hosts.

Ok, so I seem to understand that it is better to opt directly with 2.5b board and 2.5gb switch. Perhaps in the case of 1gb switches configuring the bond it would be appropriate to allocate it as a failover ...
