Hi,
I'm testing Ceph with Vmware, using Ceph-iscsi gateway. I reading documentation*  and have doubts some points:

- If I understanded, in general terms, for each VMFS datastore in VMware will match the an RBD image. (consequently in an RBD image I will possible have many VMWare disks). Its correct?

- In documentation is this: "gwcli requires a pool with the name rbd, so it can store metadata like the iSCSI configuration". In part 4 of "Configuration", have: "Add a RBD image with the name disk_1 in the pool rbd". In this part, the use of "rbd" pool is a example and I could use any pool for storage of image, or the pool should be "rbd"?
Resuming: gwcli require "rbd" pool for metadata and I could use any pool for image, or i will use just "rbd pool" for storage image and metadata?

- How much memory ceph-iscsi use? Which  is a good number of RAM?

Regards
Gesiel
