System requirements¶ At least 1GB RAM is required to operate successfully. At least 2 logical CPU cores are recommended to reduce the 100% CPU saturation risk during the synchronization period PLM process must be able to connect to all replica set nodes that could become a new primary. In non-sharded replica set deployments, this means connecting to all the nodes that could become a new primary node. To become a primary, a node must meet the following criteria: have priority greater than 0 and must be able to vote (votes: 1) is not an arbiter (arbiterOnly: false) is not hidden (hidden: false) is not delayed Note that networking issues like connection to the remote backup storage can also affect PLM performance.
