Network switch best practice


Badge +5
I have 8 port 10BaseT 10g switch and I have four nodes with dual 10g and dual 1g. I also have a 1g switch with 50 ports. If I plug all 8 10g nic into the 10g switch I will not have an uplink port. However I still have thx 8 1g nic. So this leaves me with a couple options, and I was curios what best practice would be. A few options I have consider are:

  1. Only use one of the two 10g ports per node.
  2. Configure AHV to use 10g for I/O only and 1g for connecting to the outside world. *not sure if this even doable*

Mike,

The main purpose of having a second network adapter in the server is for redundancy and high availability. We recommend connecting the two 10g links coming from the server to two separate 10g switches for this reason as well.

Since you only have a single switch, I'd lean toward connecting just a single 10g uplink from each server to your existing switch. It's worth considering adding a second 10g switch as well for high availability.

It's not possible to separate the data and management of the CVM between the 10g and 1g at this time.

Jason,

Thanks for the reply and the info. This will help me finished the 1g to 10g conversion and I can add a 2nd 10g switch to future budget needs.
