I have some question, about future plans. I know ceph is LAN DFS, not a WAN in any kind, but ;)
1. Is there any plan about tier support. Example: I have ceph cluster with fast SAS drives, and a losts of RAM, and SSD acceleration, and 10GE network. I use only RBD, and RadosGW. Cluster have relative small capacity, but its fast. I have a second cluster with diffrent configuration, with a large number of big SATA drives, and smaller number of RAM, 1Gb ethernet. Same usage as above. All i need is to have phisical 2 clusters, but with some tier function, to move old objects from fast to slow cluster (for archive), and opposite. If ceph will be very stable this can be done inside one cluster it will be much simpler, but crush need to know what is faster, and what is slower. 2. Like above two clusters this time same configurations and size, but with async replication between. Replication can be done by the external replication darmon on top of rados, or other solution. Is there any plans with any of this ?? Or something like this ??
