ONAP Lab Specification

The lab specification section provides information on hardware and network requirements

Hardware

A ONAP Open Labs are collections of dedicated hardware, generally partitioned into PODs with servers. PODs can be used for different testings like development, CI/CD, ONAP platform testing, E2E use case integration testing, Community demo, or interoperation testing with 3rd part productions. Each lab can have 1~4 PODs depending on test cases.

The lab specification section provides information for recommended hardware and network configuration.

Overview

A ONAP lab compliant test-bed provides:

  • One CentOS 7 jump server on which the installer runs
  • You may select a variety of deployment toolchains to deploy from the jump server.
  • Minimal 5 compute / controller nodes
  • More then one POD should be delivered depends on the usage scenarios.
  • A configured network topology allowing for LOM(Lights-out Management), Admin, Public, Private, and/or Storage Networks if needed.
  • Remote access through VPN

...

  • or other approach provided by individual labs
  • Security through a firewall

Hardware

Servers 

CPU:

    • Intel Xeon E5-2600v2 2658v3 Series or newer, with 12 cores and 24 hyper-threads

Firmware:

    • BIOS/EFI compatible for x86-family servers

Local Storage:

Below describes the minimum for the spec, which is designed to provide enough capacity for a reasonably functional environment.

...

 Additional and/or faster disks are nice

...

.

    • Disks: 2 1 x 1TB HDD + 1 x 100GB SSD (or greater capacity)
    • The first HDD should be used for OS & additional software/tool installation
    • The second HDD is configured for CEPH object storage
    • The SSD should be used as the CEPH journal
    • Virtual ISO boot capabilities or a separate Virtual ISO boot capabilities or a separate PXE boot server (DHCP/tftp or Cobbler)

Memory:

    • 188G 256128GB RAM Minimum

Power Supply

Single power supply is acceptable(redundant power not required/nice to have)

Networking

Network Hardware

...

  • TOR Switch
  • Router
  • others

Networking

    • 48 Port TOR Switch

    • NICs - Combination of 1GE and 10GE based on network topology options

...

    • Connectivity for each data/control network is through a separate NIC

...

    • port or a shared port. Separate port simplifies switch management however requires more NICs on the server and also more switch ports

    • BMC (Baseboard Management Controller) for lights-out

...

    • management network using IPMI (Intelligent Platform Management Interface)

Network Options

    • Option I: 4x1G Control, 2x10G Data, 48 Port Switch
      • 1 x 1G for

...

      • IPMI Management
      • 1 x 1G for Admin/PXE boot
      • 1 x 1G for control-plane connectivity
      • 1 x 1G for storage
      • 2 x 10G for data network (redundancy, NIC bonding

...

      • )
    • Option

...

    • III:

...

    • 2x1G Control,

...

    • Connectivity to networks is through VLANs on the Control NIC
    • Data NIC used for VNF traffic and storage traffic segmented through VLANs

...

    • 1x10G Data(redundancy nice to have), 1x10G Control or Storage(if needed, redundancy nice to have), 48 Port Switch
      • Data NIC used for VNF traffic

...

      • 1 x 1G for

...

      • IPMI mangement
      • 1 x 1G for Admin/PXE boot

...

      • 1 x 10G for control-plane connectivity/storage

...

      • (if needed,  control plane and storage segmented through VLANs)
      • 1 x 10G for data network

Documented configuration to include:

    • Subnet, VLANs

...

    • IPs
    • Types of NW -

...

    • LOM, public, private, admin, storage

...

    • Default gateways

Remote Management

Remote access is required for …

    • Developers to access deploy/test environments (credentials to be issued per POD / user)

...

    • at 100Mbps upload and download speed

OpenVPN is generally used for remote however community hosted labs may vary due to company security rules. For POD access rules / restrictions Please refer to individual lab documentation/wiki page as each company may have different access rules and acceptable usage policies.

Basic requirements:

    • SSH sessions to be established (initially on the jump server)
    • Packages to be installed on a system

...

    • by pulling from an external repo.

Firewall rules accommodate:

    • SSH sessions

...

LightsLights-out management network requirements:

    • Out-of-band management for power on/off/reset and bare-metal provisioning
    • Access to server is through a lights-out-management tool and/or a serial console
    • Refer to applicable light-out

...

    • management information from server manufacturer, such as ...
      • Intel lights-out RMM
      • HP lights-out ILO
      • CISCO lights-out UCS

POD


In the following table, we define 3 types of Pod based on the resource usage assumption and each POD recommended configuration is described in the following.  Please note in lab and real deployment scenarios, resource can be over subscribed depending on workload. Also we assume that ONAP platform will be deployed in a separate pod from VNFs.
