Hi,
So I have gotten my new cluster up and running based on the nice Fujutsu TX1320M3 - and I have for now only 3 nodes running with 2 OSD's each.
This works nice and I get an average 1ms read/write latency according to the ceph dashboard statistics, which is good enough for me - so I am wondering what benefin besides more resilience I will get if I deploy yet another 2 nodes with 2 OSD's each.
The alternative is to put 2 more OSD's into each of the 3 nodes.
This should give me a little more bandwidth to write, same scalability - and not to mention - power consumtion savings from deploying yet another two nodes.
So - I guess its a no brainer?
For a homelab - 3 nodes is "safe" enough right?
I do have backup of the important stuff, ie. VM's running on ceph and the rest of the data can be recreated from configuration.
As you can see its not very busy my cluster
