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?
yes
- 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"?
that's just an example, yes
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?
you can even store the metadata elsewhere in newer versions, see
options in the config file
- How much memory ceph-iscsi use? Which is a good
number of RAM?
since it can't cache anything: virtually nothing
