[ovirt-users] oVirt storage best practise

Hi, does a storage best practise document for oVirt exist? Some examples: oVirt allows to extend an existing storage domain: Is it better to keep a 1:1 relation between LUN and oVirt storage domain? If not, is it better to avoid adding LUNs to an already existing storage domain? Following the previous questions: Is it better to have 1 Big oVirt storage domain or many small oVirt storage domains? There is a max num VM/disks for storage domain? In which case is it better to use "direct attached lun" with respect to an image on an oVirt storage domain? Example: Simple web server: ----> image Large database (simple example): - root,swap etc: 30GB ----> image? - data disk: 500GB -----> (direct or image?) Regards, Stefano
