[SOLVED] hyperconverged ceph cluster network question

[luphi]

all,

I have a dual port 10GB NIC for CEPH in each server of a three node cluster.

Option 1: using a LACP bond for private and public CEPH traffic and distribute the bonds across different switches
Option 2: separated private and public networks without redundancy

Which option would one prefer, and why?

Cheers,
luphi

The Ceph cluster network is optional to put the heartbeat and replication traffic between the OSDs on a different network. I would keep it simple but redundant. If you realize that your network is the bottleneck, you could either add more NICs to use as a separate Ceph cluster network or tear down the bond and go without redundancy.

Hello Aaron,

that were also my thoughts.
Thank you for confirmation.
