- Andy Mayer
Description
The LogicalNodeDesc information element describes compute, memory and I/O requirements that are to be associated with the logical node of infrastructure. The logical node requirements are a sub-component of the VDU level requirements.

logicalNodeRequirements | M | 0..* | NameValuePair | The logical node-level compute, memory and I/O requirements. An array of key-value pairs that articulate the deployment requirements. This could include the number of CPU cores on this logical node, a memory configuration specific to a logical node (e.g. such as available in the Linux kernel via the libnuma library) or a requirement related to the association of an I/O device with the logical node.
