I've using xcp-ng with NFS Shared Storage for some months now and I am happy with it so far.
I've some ssds in a 3 server setup and I'd like to test xostor. Before I will setup xostor, there are some questions regarding it, as I am only familiar with virtuozzo/acronis-storage and ceph so far. Are there the same restrictions for using xostor, that exists in ceph e.g.?

• only enterprise ssds because of power loss protection
• do not use Raids ( especially Raid 0 ) if the controller is capable of using HBA Mode. I've an Dell H330 Controller and if Raid is no problem, I'd like to setup OS with Hardware Raid 1 and xostor on the rest of the ssds with raid0 arrays per each disk. If HBA mode is prefered, I need to stick with Software Raid 1, I think. Software Raid 1 is working fine, but I've had some problems in the past if the boot drive of the mirror died...
• I've installed xen-orchestra manually. Once xostor is installed, will the xostor button in xen orchestra will have a function or is it only available within the XOA appliance?

Thanks for your answers!
