[ovirt-users] Re: Number of data bricks per oVirt HCI host

Imagine you got a host with 60 Spinning Disks -> I would recommend you to split it to 10/12 disk groups and these groups will represent several bricks (6/5). Keep in mind that when you start using many (some articles state hundreds , but no exact number was given) bricks , you should consider brick multiplexing (cluster.brick-multiplex). So, you can use as many bricks you want , but each brick requires cpu time (separate thread) , tcp port number and memory. In my setup I use multiple bricks in order to spread the load via LACP over several small (1GBE) NICs. The only "limitation" is to have your data on separate hosts , so when you create the volume it is extremely advisable that you follow this model: hostA:/path/to/brick hostB:/path/to/brick hostC:/path/to/brick hostA:/path/to/brick2 hostB:/path/to/brick2 hostC:/path/to/brick2 In JBOD mode, Red Hat support only 'replica 3' volumes - just to keep that in mind. From my perspective , JBOD is suitable for NVMEs/SSDs while spinning disks should be in a raid of some type (maybe RAID10 for perf).

I have some hosts that could provide up to 6 JBOD disks for oVirt data (not arbiter) bricks Would this be workable / advisable ? I'm under the impression there should not be more than 1 data brick per HCI host . Please correct me if I'm wrong.
