# Bridge device entry
# This device is passed to PVC and is used when creating bridged networks. Normal managed networks are
# created on top of the "cluster" interface defined below, however bridged networks must be created
# directly on an underlying non-vLAN network device. This can be the same underlying device as the
# upstream/cluster/storage networks (especially if the upstream network device is not a vLAN itself),
# or a different device separate from the other 3 main networks.

# Memory tuning

# > This option is *only* applied at cluster bootstrap and cannot be changed later

#pvc_osd_memory_limit: 939524096
#
# Zookeeper heap memory limit, sets Xms and Xmx values to the Java process; default is 512M.
# > WARNING: Unless you have an extremely limited amount of RAM, changing this setting is NOT RECOMMENDED.
#            Lowering the heap limit may cause poor performance or crashes in Zookeeper during some tasks.
#pvc_zookeeper_heap_limit: 128M   # 1/4 of default

# CPU pinning configuration via cset
# > ADVANCED TUNING: For most users, this is unnecessary and PVC will run fine with the default scheduling.
# > These options can be set to maximize the CPU performance of the Ceph subsystem. Because Ceph OSD
#   performance is heavily limited more by CPU than anything else, for users with a lot of relatively slow CPU
#   cores, or for those looking to get maximum storage performance, tuning the pinning options here might
#   provide noticeable benefits.
# > This configuration makes use of the cset command and will dedicate a specific number of CPU cores to the
#   Ceph OSD processes on each node. This is accomplished by using cset's shield mechanism to create a cgroup
#   which will contain only Ceph OSD processes, while putting everything else onto the remaining CPUs.
# > Avoid using this tuning if you have less than 8 total CPU cores (excluding SMT threads). Otherwise, you
#   might not have enough CPU cores to properly run VMs, unless you are very careful with vCPU allocation.
# > Like the 'pvc_nodes' dictionary, these options are set per-host, even if all hosts are identical. This
#   is required to handle sitations where hosts might have different CPU topologies. Each host can have a
#   specific set of CPUs that are included in the shield.
# > Ensure that you know which CPU cores are "real" and which are SMT "threads". This can be obtained using
#   the 'virsh capabilities' command and noting the 'siblings' entries for each CPU.
# > Ensure you consider NUMA nodes when setting up this tuning. Generally speaking it is better to keep the
#   OSD processes onto one NUMA node for simplicity; more advanced tuning is outside of the scope of this
#   playbook.
# > You should set a number of cores in the shield (along with their respective SMT threads) equal to the
#   number of OSDs in the system. This can be adjusted later as needed. For instance, if you have 2 OSDs per
#   node, and each node has a 10-core SMT-capable CPU, you would want to assign cores 0 and 1 (the first two
#   real cores) and 10 and 11 (the SMT siblings of those cores in 'virsh capabilities') in the cset.
