Sunlight Software Defined Networking (SDN), a component of NexVisor HCI, embeds fast network switch support in every hypervisor node, enabling fully virtualised network deployments. Sunlight SDN enables the creation of virtual private networks, and bridging and routing between them. In addition Sunlight SDN allows you extend your AWS elastic network to your edge and on-prem Sunliight clusters. Sunlight SDN allows you to take advantage of the full available bandwidth of multiple 10/100Gb NICs with NIC teaming for the highest workload performance.

Create virtual private networks

  • Create unlimited virtual private networks
  • Enable access to direct attached network segments directly from VMs
  • Enable multi-tenancy and separate security zones

True NIC teaming

  • Aggregates multiple NICs into a single virtual interface
  • Take advantage of full network bandwidth capability of the physical hardware
  • Virtual interface deals with physical NIC failure gracefully

Integrates with AWS elastic networking

  • Take advantage of AWS elastic network architecture
  • Map elastic IPs to Sunlight instances
  • Extend AWS elastic network interfaces securely to on-premise/edge clusters

Easy to implement and manage

Sunlight is easy to install - the complete Sunlight HCI stack can be installed on a bare-metal server in 10 minutes, or on-demand in AWS. AWS AMIs are binary compatible - so can be migrated instantaneously. Sunlight is easy to manage - it includes a full dashboard that allows you to manage all aspects of your Sunlight cluster, including fine-grained control of CPU, storage and network configuration and performance. The dashboard is installed as part of the HCI stack and is highly-available by design across the cluster.


Sunlight is designed with security at its core. All components of the Sunlight stack are hardened. Thanks to Sunlight’s fine grained CPU and memory allocation it is possible to physically guard against CPU memory exploits. Control of IO interfaces allows you to separate content and network traffic so there is no sharing of physical drives or network physical interfaces. Data can be encrypted at rest through hardware acceleration

Low Cost

Sunlight is priced on a per-node basis - no penalties for high core-density CPUs. Sunlight is available as a monthly or annual subscription (or hourly subscription in AWS).
