      In this post, @lawrencesystems described having 6GB RAM and 16 CPUs assigned to the Xen Orchestra host.

      Right now my XO instance controls 1 host with 2CPU/2 GB RAM. As my cluster grows, how should I scale it?

        Hi,

        "It depends" is the answer here 🙂 Depends on:

        • the number of concurrent users on your XO instance
        • the size/frequency/number of backup jobs you have
        • the number of hosts and VMs managed by XO

        Frankly, for a small setup (less than 4/5 hosts) with one users and few backup jobs, the default 2vCPU/2GiB RAM is enough. Especially since we improved various process to happen in a dedicated worker 🙂
