I don't agree with this point. 3.10 kernel version is enough, becault Redhat ceph enterprise product is running on Rhel 7 which is 3.10 kernel version too. though redhat 3.10 kernel version is different from upstream kernel 3.10 ; If you use Centos or Rhel Linux distribution as a ceph client , it is not a problem.

If you were using Ceph-fuse, librbd, etc then the version of the kernel on the client wouldn't matter.
