[one-users] IBM Blade configuration for openebula cloud

[Jaime Melis]

Hi Branko,

sorry for the delay. Take for instance the iSCSI drivers (similar with
LVM), what OpenNebula does there is connect to the iSCSI server and manage
(create, exporte, remove) the iSCSI targets, and discovers them from the
host nodes. You could take iSCSI drivers as a model and make them work with
FB very easily, you just need to implement some actions [1].

However I'd like to stress what Hans-Joachim said earlier in this thread.
You could set up an underlying shared storage configuration using FB and
use the "shared" drivers. That would be absolutely transparent to
OpenNebula. As long as a certain path, say /var/lib/one/datastores is
available in all hosts and RW shared, OpenNebula will work perfectly, and
no coding is needed.

Cheers,
Jaime
