advantage separate cluster network on single interface
Hi I wonder if there is any (theoretical) advantage running a separate backend network next to the public network (through vlan separation) over a single interface I googled a lot and while some blogs advice to do so, they do not give any argument that supports this statement Any insights on this is much appreciated Thanks Marcel
hello as far as I know there is no perf advantage to do this. Personnaly I'm doing it in order to monitoring the two different bandwidth usage. oau Le mardi 16 juin 2020 à 16:42 +0200, Marcel Kuiper a écrit :

We have a dev cluster to test things on ceph, that only have one 1gig nic network. Although it can work we noticed major impact with latencies when the cluster is balancing or under heavy load. On Tue, Jun 16, 2020 at 07:54 Olivier AUDRY <olivier@nmlq.fr> wrote:

In my opinion, having the additional and error prone work of configuring additional networks, maintain and monitor them outweighs the small benefits. In the past, we saw lots of clusters that had reduced availability due to misconfigured or broken networks. This got so far that we included a network packet loss monitoring into our Ceph management solution to help customers track down their network issues. Therefore choosing a single network strongly increases your reliability and availability of your cluster. -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@croit.io Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Di., 16.
