Re: max pool size (amount of data/number of OSDs)

 Hi,
Is there any information on this issue? Max number of OSDs per pool, or maxpool size (data) as opposed to cluster size? Thanks!

Subject: max pool size (amount of data/number of OSDs)


Hi,
There are various articles, case studies, etc about large ceph clusters, storing 10s of PiB,with CERN being the largest cluster as far as I know.
Is there a largest pool capacity limit?  In other words, while you may have a 30PiB cluster,is there a limit or recommendation as to max pool capacity. For example, in the 30PiB example,is there a limit or recommendation that says do not have a pool capacity of higher than 5iB, for 6pools in that cluster at a ttotal of 30PiB?

I know this would be contingent upon a variety of things, including, but not limited to network throughput, individual serversize (disk size and number, memory, compute). I am specifically talking about s3./rgw storage.

But is there a technical limit, or just a tested size, of a pool? Should I createdifferent pools when a given pool would otherwise reach a size capacity of Xor have N osds or PGs in it, when considering adding additional osds?
Thanks for any info
-Chris
