This is useful to # help limit the impact that noisy elements may have on other elements, e.g. busy VMs on # OSDs, or system processes on latency-sensitive VMs. # > To enable tuning, set enabled to yes. # > Within "nodes", two counts are specified: # * system_cpus: The number of CPUs to assign to the "system" slice, i.e. all non-VM, # non-OSD processes on the system. Should usually be at least 2, and be # higher on the coordinators of larger clusters (i.e. >5 nodes). # * osd_cpus: The number of CPUs to assign to the "osd" slice, i.e. all OSD processes. # Should be at least 1 per OSD, and ideally 2 per OSD for best performance. # A third count, for the VM CPUs, is autogenerated based on the total node CPU count and # the above two values (using all remaining CPUs). # > Tuning is done based on cores; for systems with SMT (>1 thread-per-core), all SMTs within # a given core are also assigned to the same CPU set. So for example, if the "system" group is # assigned 2 system_cpus, there are 16 cores, and there are 2 threads per core, the list will be: # 0,1,16,17 # leveraging the assumption that Linux puts all cores before all threads. # > This tuning section under "nodes" is global to the cluster; to override these values on # a per-node basis, use the corresponding "cpu_tuning" section of a given "pvc_nodes" entry # as shown below. # > If disabled after being enabled, the tuning configurations on each node will be removed # on the next run. A reboot of all nodes is required to fully disable the tuning. # > IMPORTANT NOTE: Enabling CPU tuning requires a decent number of CPU cores on the system. For very # low-spec systems (i.e. less than at least 12 cores per node), it is advisable to leave this tuning # off, as otherwise very few cores will actually be allocated to VMs. With a larger number (>16 or so), # this tuning is likely to greatly increase storage performance, though balance between the VM workload # and total number of cores must be carefully considered. cpu_tuning: enabled: no # Disable or enable CPU tuning; recommended to enable for optimal storage performance nodes: system_cpus: 2 # Set based on your actual system configuration (min 2, increase on coordinators if many nodes) osd_cpus: 2 # Set based on your actual number of OSDs (for optimal performance, 2 per OSD) # Configuration file networks # > Taken from base.yml's configuration; DO NOT MODIFY THIS SECTION. pvc_upstream_device: "{{ networks['upstream']['device'] }}" pvc_upstream_mtu: "{{ networks['upstream']['mtu'] }}" pvc_upstream_domain: "{{ networks['upstream']['domain'] }}" pvc_upstream_netmask: "{{ networks['upstream']['netmask'] }}" pvc_upstream_subnet: "{{ networks['upstream']['subnet'] }}" pvc_upstream_floatingip: "{{ networks['upstream']['floating_ip'] }}" pvc_upstream_gatewayip: "{{ networks['upstream']['gateway_ip'] }}" pvc_cluster_device: "{{ networks['cluster']['device'] }}" pvc_cluster_mtu: "{{ networks['cluster']['mtu'] }}" pvc_cluster_domain: "{{ networks['cluster']['domain'] }}" pvc_cluster_netmask: "{{ networks['cluster']['netmask'] }}" pvc_cluster_subnet: "{{ networks['cluster']['subnet'] }}" pvc_cluster_floatingip: "{{ networks['cluster']['floating_ip'] }}" pvc_storage_device: "{{ networks['storage']['device'] }}" pvc_storage_mtu: "{{ networks['storage']['mtu'] }}" pvc_storage_domain: "{{ networks['storage']['domain'] }}" pvc_storage_netmask: "{{ networks['storage']['netmask'] }}" pvc_storage_subnet: "{{ networks['storage']['subnet'] }}" pvc_storage_floatingip: "{{ networks['storage']['floating_ip'] }}"
