Ceph can serve an infinite number of volumes to clients, but that is not really your question.
ceph-volume Is used to prepared a disk to be consumed by Ceph for serving capacity to users. The prepared volume will be served by an OSD and join the RADOS cluster, adding its capacity to the cluster’s.
If your question is how many disks you can attach to a single cluster today, the sensible answer is “a few thousand”. You can push farther using a few tricks. Scale increases over time, but I would say 2,500-5,000 OSDs is a reasonable limit today.
