This article describe the components needed to build a production VOS Cloud system for 25 channels.

First lets start with the OpenStack Reference Architecture. For that you need:

  • Firewalls - redundant
  • Load balancers – redundant
  • Router with SDN capabilities
  • Networking Control Plane, StorageTraffic and OpenStack management segmented to provide QoS
  • Dedicated Servers for ControlPlane
  • Dedicated Servers for Computenodes
  • Dedicated Servers for CloudLinks
  • Cloud storage – SSD
  • Optional storage – applicationspecific

After you have the OpenStack deployment environment ready, and you downloaded the HEAT template from VOS HUB, you now need to create your VOS node size.

As a reminder, VOS Cloud require minimum of 3 nodes in order to build a cluster. 

To build a 25 OTT HD production system you will need the components listed below:
Important notes:
  • The node sizing include transcoding, packaging and origin functionality.
  • The system sizing does NOT include any nodes for redundancy
  • System does NOT include storage for Time-Shift application
  • The number of compute nodes are based on Harmonic HD Gold profiles (6 profiles, top profile is 1080p60) and can be used as a reference only. For more accurate information about a system you want to build, please contact us. 
1. VOS Cloud cluster - 5 physical hosts (compute nodes) each with:
  • Dual CPU machines
  • CPU version: E5-2697v4 
  • RAM: 256 GB
  • Storage: 300GB or more
  • Network card: 10Gbps or more
2. VOS Cloudlink application - 2 physical hosts (running on HW outside of the OpenStack environment, as on OVA container, connected to the Video Multicast network), each with:
  • CPU version: E5-2697v3 or above
  • RAM: 64 GB or more
  • Storage: 300GB or more
  • Network card: 1Gbps or more, 2 NICs
