Re: [ceph-users] ceph on two data centers far away

May i ask how are your two data centers are connected together ? On Thursday, 20 October 2016, yan cui wrote: > 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

Re: [ceph-users] ceph on two data centers far away

for example, to have one cluster with four instances, two on each data center sharing the same storage cluster, so if data center #1 let's said goes down along with instances 1 & 2, you can still run the cluster with instances 3 & 4 on the data center #2 with the same storage cluster pool and no

Re: [ceph-users] ceph on two data centers far away

What is the use case that requires you to have it in two datacenters? In addition to RBD mirroring already mentioned by others, you can do RBD snapshots and ship those snapshots to a remote location (separate cluster or separate pool). Similar to RBD mirroring, in this situation your client writes

Thanks, that's too far actually lol. And how things going with rbd mirroring? *German* 2016-10-20 14:49 GMT-03:00 yan cui : > 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. > >

Re: [ceph-users] ceph on two data centers far away

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* 2016-10-18 16:22 GMT-03:00 Sean Redmond : > Maybe

Maybe this would be an option for you: http://docs.ceph.com/docs/jewel/rbd/rbd-mirroring/ On Tue, Oct 18, 2016 at 8:18 PM, yan cui wrote: > Hi Guys, > >Our company has a use case which needs the support of Ceph across two > data centers (one data center is far away

[ceph-users] ceph on two data centers far away

Hi Guys, Our company has a use case which needs the support of Ceph across two data centers (one data center is far away from the other). 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
