Hi,
I'm currently reading the documentation about stretched cluster,
I would like to known if it's needed or not with this kind of 3 dc
setup:
3km (0.2ms)
DC1--------------DC2
30km(3ms) | | 30km (2-3ms)
|--------DC3------
DC1 && DC2 are near each other, small latency. (0.2ms)
DC3 is at 30km with bigger latency. (2ms)
separated links between dc with different physical path
1 monitor on each dc
osd on DC1/DC2, with size=4
Cluster is full nvme or ssd, lowest latency is required for osd
replication.
Now, I really don't known if latency monitor at DC3 could have an
impact on osd read/write latency is this monitor elected ?
vs stretched cluster with osd only use local dc monitors ?
What is the advantage of stretch cluster here ? (with good redudant
links between sites)
