I normally assume that any performance gain from directlly attaching a LUN to a Virtual Machine then using it in the traditional way are so little to compensate the extra hassle to do that. I would avoid as much as I cacn use it, unless it is for some very special reason where you cannot do in

Direct luns are disks that are not managed by oVirt. Ovirt communicates directly with the lun itself, without any other layer in between (like lvm in image disks). The advantage of the direct lun is that it should have better performance since there's no overhead of another layer in the middle.

2017-06-08 Thread Stefano Bovina
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
