To develop and agree the requirements of the hardware delivery validation, per the CNTT request, which may be included as part of the OVP Infrastructure testing requirements.


There are a number of open questions that should reach community agreement BEFORE trying to reach agreement on specific tooling (basically, lets agree the WHAT before the HOW).  The following questions have inputs have been pulled from email discussions intended to drive input input this working session for Prague.  

Overall Objective:

  1. Process, requirements (developed within CNTT RC), and tooling to enable automated checking of hardware and settings installed a lab that will be used for NFVI or VNF testing. 
  2. First "release" is focused on "read-only" vie of the hardware / settings.  Future releases might add "read/write" configuration.

What specifically needs to be "checked" in the validation, in terms of parameters and configuration?  (RAM, Disks and Disk Sizes, CPU info, Network Interfaces, Network Connectivity, etc.)

Test Type



Checked When (via)

BIOS Settings

Verifies all applicable BIOS settings per hardware model.

  • Boot mode
  • Boot Sequence Retry
  • AC Power Recovery
  • Power Setting (balanced / performance)
  • Virt. Technology
  • Hyper Threading
  • Trusted platform module

Firmware Settings

Verifies all applicable Firmware settings

  • BIOS
  • Storage Array Controller
  • NIC (Intel X710)
  • PXE Enabled Ports

Boot Order

Verifies applicable boot order settings

First boot, Second boot

Hardware Health

Queries Intelligent Platform Management Interface (IPMI) is for all hardware components and their health status

  • Raid
  • System Board
  • CPU temp
  • Power Supply

PCI Slot Status & MAC

Which cards are in which slot, which slot is assigned to which CPU, slot type

  • card(s) in slot/port/PCI partition
  • Slot speed / type
  • CPU / Slot assignment

NICValidates that all NICs are in the correct slots, with a healthy status (per IPMI), have correct MAC addresses, and are detecting a cable connection (or not). 
  • Correct LLDP neighbor
  • MAC Addresses(es)


Check for existence of logs

Physical event logged.  E.g. chassis open on power up

IPMI Users

Check for existence of user accounts

  • Check if IPMI is available on the network
  • Check existing accounts
  • Check for use of default credentials

Hardware Inventory

Inventory of h/w on platform..

CPU and count, NUMA topology, CPU Freq., RAM, speed, size, model, etc

Physical Disk Configuration

Verifies storage / disk config (type, size)

  • Physical disk type
  • card/port location
  • capacity

SRIOV Port Validation

Verifies global and NIC level enabled

Confirm setting is enabled (or none)

Hardware Check

Verifies basic OS config attributes (i.e. Linux running on the host and reporting these values)

  • RAM size
  • # of cores (/proc/cpu)

Out of scope for HDV (possibly for Functest):

  • MTU path verification

Note as per email discussion:-

“What needs to be validated",

We can share the details which p/m are validating as per  table above or any addition” 

the first goal is validation of the hardware against a bill of material or similar.  This would also check against minimums agreed / set by the CNTT, so the environment or lab can be vetted to meet the requirements for VNF certification, etc.

“How it is validated" 

We can present a small demo with our automated architecture approach”

What is the entry to the HDV (hardware delivery validation)? Is this information contained / pulled from the PDF type "file," if yes, does that "file" contain all required info? If not, then what?

  • Mike:  Entry will be remote access into the host.  IPMI interface / logs used for verification.  Tool/discussion will be needed for access and automation.
  • FQ: I would think the entry would be from PDF. 
  • Vaibhav:  For Validation, Remote access to host will definitely be needed, but results need to be compared with the expected outcome (PDF, or a yaml contains all p/ms.
  • dbalsige: The PDF/IDF information should be there before running validation. Validation would compare reality in Lab environment with PDF/IDF information. Therefore the PDF/IDF should contain all detailed information required for HDV.

When does the HDV occur, pre stack deployment, post stack deployment? How does this handle the cloud native environment (i.e. no open stack)?

  • Mike:  Pre-software stack deployment.  i.e. RI Design complete (PDF) > Rack, Stack/Cabling > Network Config > “HVD” > then, passed on to software deployment team.
  • FQ: Agree. HDV is before any software is deployed in the infrustructure.
  • Vaibhav : Agree, it would be Pre-stack deployment to verify HDV.
  • dbalsige: Agree. as early as possible. Some HDV tests (see above) will probably require booting an OS (e.g. introspection kernel + ramdisk) in my opinion. What about doing "in-between" stack validation, by either an CNTT-HDV-ramdisk before the final Operating System installation or even on the final Operating System? The PDF/IDF would also contain physical lab setup (different physical networks, underlay addressing, VLANs, NIC mappings, storage layout, etc...) but no stack specific (OpenStack or K8s) configuration. From that point on, the stack software (K8s or OpenStack) could be installed in an automated way. We would leave every option open and decouple the physical Lab properties from the stack software installation & configuration.

If the requirement is pre stack deployment, how is the validation done, i.e using the BMC interfaces?  (this will require significant hardware vendor input).

  • Mike:  Yes, this Baseboard Management Controller (BMC), or Integrated Lights Out (iLO) management / NIC port, dedicated to accessing the host for remote management.
  • [fq]we are using IPMI at first, and now also utilize redfish. It really requires significant hardware vendor input, and lots of adaptation effort
  • Vaibhav : Our automated validation is also designed based on redfish and in my view each H/w vendors support that as well.
  • dbalsige: In a perfect world the BMC approach could work. Completely depends on the H/W vendor, as mentioned above. Some HDV (e.g. basic network connectivity on all (bonded and DPDK) NICs is very hard to check from the BMC). In my opinion, booting an Operating system in some form is still the simplest approach to verify such H/W settings.

What are the required output / formats, etc.?

  • Mike: Varies by test type: Either Boolean, Text, Size, Version/Value, OK (health), Serial #s, etc


  • Part of CNTT certification is checking the hardware
  • What things are important to check?
  • When do these things get checked (pre/post stack)?
  • Potential futures:
    • Switches (check ports, vlan trunks, etc)
    • PDUs 
    • Intelligent racks
    • ...?
