XCP-ng high availability & xoSAN basic quesstions
-
What kind of HA feature do we have in XCP-ng?
IF you have VM HA, what is the level protection of this? is it only IF the VM level is in trouble right?
What if we have VM HA, but the service or app inside the VM is in trouble?All hypervisor product mostly provide HA at VM level right, not the service/processes/apps running inside the OS?
Where is XCP-ng road map?
is vSAN equivalent in principle to xoSAN?
I have read the doc here: https://xen-orchestra.com/docs/xosan.html
is that mean to make xoSAN that i have to build separate dedicated "xoSAN VM" for each host?What is the alternative option of storage to make xoSAN work? local storage of host only?
What about direct attached storage? exclude anything external storage except DAS?
What is supported networking protocol and/or storage protocol?
It just aggregating separate storage of each host in one consolidated virtual storage right? and thats why we are recommended to have at least 10Gb ethernet?Thank you,

Existing HA level is at VM level. It means, if the VM is down (or the host on the VM is running is down), it will be booted on a working host in that pool.
For hyperconvergence, it's far from being a miracle solution. It costs a lot of thinking, planning and maintenance (and careful usage of it).
Like HA in the end.
So before asking for advanced features, it's good to think about what you really need.
