<p>Using FUSE clients:</p>
<p>For every write, there are three writes on the network (one per
brick in your x3 config). So, outside of bandwidth requirements,
you have TCP connection limits which comes with filedescriptor
limits.</p>
<p>If all three bricks are on the same server, then you have a max
for that server divided by three. If each brick is on its own
server, then you don't have that 1/3rd problem.<br>
</p>
<p>The idea of GlusterFS is horizontal scaling, so you would add
more bricks on more hosts to scale when you reach that arbitrary
limit.</p>

<p>Using NFS:</p>
<p>You have the single connection from the client to the NFS server,
then the fan out to the bricks.<br>

<div>Hi,</div>
<div>I am running a GlusterFS cluster in Kubernetes.
This has a single 1x3 volume. But this volume is
mounted by around 30 other docker containers.
Basically each docker container represents a separate
"user" in our multi-tenant application. As a result
there is no</div>
<div>conflicting writes among the "user"s. Each user
writes to their own folder in the volume.</div>
<div><br>
</div>
<div>My question is how many clients can mount a
GlusterFS volume before it becomes a performance
issue? </div>
<div><br>
</div>
<div>Thanks,</div>
