Deploy Ceph on the secondary datacenter for DR
Hi everyone, Currently, our client application and Ceph cluster are running on the primary datacenter. We’re planning to deploy Ceph on the secondary datacenter for DR. The secondary datacenter is in the standby mode. If something went wrong with the primary datacenter, the secondary datacenter will take over. The possible way would work in this case is that adding hosts from the secondary datacenter into the existed Ceph cluster in the primary datacenter. By this way, it would add more latency for client requests since client from primary datacenter might connects to OSD hosts in the secondary datacenter) Are there any special configurations in Ceph that fulfill this requirement? [cid:image001.png@01D6380A.599C1D00] I truly appreciate any comments! Nghia.

What is the application? CephFS? RBD? RGW? The second datacenter indeed adds latency, so I would be very, very careful with that. Wido
I truly appreciate any comments!

Hi Wido, It is a Java application that uses librados to connect directly to the cluster. -- Nghia Viet Tran (Mr) mgm technology partners Vietnam Co.
