sorry for the late reply.
We use exactly that setup
10G - 10G - 1G (arbiter on a little desktop box)
All drives are SSDs
Because the arbiter only sees the metadata , 1GB is more than enough
On a VM host cluster the charts the peak activity for the arbiter rarely
exceeds a couple Mb/s during normal ops and even when healing after host
maintenance its less than 100Mb/s

<div>Hi Filipe,</div>

<div>I think it would probably be fine. The Red Hat Storage docs
list the important thing being <i>5ms latency</i>, not link

<div>I'm close to deploy my first GlusterFS replica 3

<div><br>
Below I will describe my hardware / plans:<br>
<br>
Node1: two bricks, 2 x raid0 arrays 40gbe network<br>
Node2: two bricks, 2 x raid0 arrays 40gbe network<br>
Node3: Arbiter 1gbe network<br>
<br>
Between Node1 and Node2, I have a 40gbe network.<br>
<br>
But the arbiter has 1 gbe network.<br>

The question is, can arbiter run in a slow network ? It
will affect the general performance of volume?</div>
