Multiple Cache Pool with Single Storage Pool

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm new with CEPH cache tiering. Is it possible to have multiple cache pool with single storage pool backend? For example I have some compute nodes with its own local SSDs. I want each compute node has its own cache by using its own local SSDs. The target is to minimize load to storage pool backend.

If yes, what will be used for RBD client pool name, cache pool name or storage pool name? How to make sure that RBD client will only use cache pool constructed with its own local SSDs, not other nodes local SSDs?

Frankly, I'm looking for RBD client cache on SSDs, but it seem has not available yet.

Best regards,
