Thanks, that's too far actually lol. And how things going with rbd mirroring?

The two data centers are actually cross US. One is in the west, and the other in the east.We try to sync rdb images using RDB mirroring.2016-10-20 9:54 GMT-07:00 German Anders <ganders@xxxxxxxxxxxx>:from curiosity I wanted to ask you what kind of network topology are you trying to use across the cluster? In this type of scenario you really need an ultra low latency network, how far from each other?Best,German

The experience of using one data center is good. We did some benchmarking on two data centers, and the performance is bad because of the synchronization feature in Ceph and large latency between data centers. So, are there setting ups like data center aware features in Ceph, so that we have good locality? Usually, we use rbd to create volume and snapshot. But we want the volume is high available with acceptable performance in case one data center is down. Our current setting ups does not consider data center difference. Any ideas?Thanks, Yan--Think big; Dream impossible; Make it happen.
