|

|
# most users would be able to use the default without too much issue. Read the following notes
|
|
# carefully to determine if this setting should be enabled in your cluster.
|
|
# > NOTE: CPU tuning is only supported on Debian Bullseye (11) or newer
|
|
# > Defines CPU tuning/affinity options for various subsystems within PVC. 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.
