HPA Requirements
----------------
1. SR-IOV Passthrought
Definitions of SRIOV_Port are necessary if VDU supports SR-IOV. Here is
an example.
.. code-block:: yaml
node_templates:
vdu_vNat:
SRIOV_Port:
attributes:
tosca_name: SRIOV_Port
properties:
virtual_network_interface_requirements:
- name: sriov
support_mandatory: false
description: sriov
requirement:
SRIOV: true
role: root
description: sriov port
layer_protocol: ipv4
requirements:
- virtual_binding:
capability: virtual_binding
node: vdu_vNat
relationship:
type: tosca.relationships.nfv.VirtualBindsTo
- virtual_link:
node: tosca.nodes.Root
type: tosca.nodes.nfv.VduCpd
substitution_mappings:
requirements:
sriov_plane:
- SRIOV_Port
- virtual_link
node_type: tosca.nodes.nfv.VNF.vOpenNAT
2. Hugepages
Definitions of mem_page_size as one property shall be added to
Properties and set the value to large if one VDU node supports
huagepages. Here is an example.
.. code-block:: yaml
node_templates:
vdu_vNat:
Hugepages:
attributes:
tosca_name: Huge_pages_demo
properties:
mem_page_size:large
3. NUMA (CPU/Mem)
Likewise, we shall add definitions of numa to
requested_additional_capabilities if we wand VUD nodes to support
NUMA. Here is an example.
.. code-block:: yaml
topology_template:
node_templates:
vdu_vNat:
capabilities:
virtual_compute:
properties:
virtual_memory:
numa_enabled: true
virtual_mem_size: 2 GB
requested_additional_capabilities:
numa:
support_mandatory: true
requested_additional_capability_name: numa
target_performance_parameters:
hw:numa_nodes: "2"
hw:numa_cpus.0: "0,1"
hw:numa_mem.0: "1024"
hw:numa_cpus.1: "2,3,4,5"
hw:numa_mem.1: "1024"
4. Hyper-Theading
Definitions of Hyper-Theading are necessary as one of
requested_additional_capabilities of one VUD node if that node
supports Hyper-Theading. Here is an example.
.. code-block:: yaml
topology_template:
node_templates:
vdu_vNat:
capabilities:
virtual_compute:
properties:
virtual_memory:
numa_enabled: true
virtual_mem_size: 2 GB
requested_additional_capabilities:
hyper_threading:
support_mandatory: true
requested_additional_capability_name: hyper_threading
target_performance_parameters:
hw:cpu_sockets : "2"
hw:cpu_threads : "2"
hw:cpu_cores : "2"
hw:cpu_threads_policy: "isolate"
5. OVS+DPDK
Definitions of ovs_dpdk are necessary as one of
requested_additional_capabilities of one VUD node if that node
supports dpdk. Here is an example.
.. code-block:: yaml
topology_template:
node_templates:
vdu_vNat:
capabilities:
virtual_compute:
properties:
virtual_memory:
numa_enabled: true
virtual_mem_size: 2 GB
requested_additional_capabilities:
ovs_dpdk:
support_mandatory: true
requested_additional_capability_name: ovs_dpdk
target_performance_parameters:
sw:ovs_dpdk: "true"
