Sunlight Photon is the fastest and lowest latency NVMe-over-Fabrics appliance on the market today. Photon integrates seamlessly with Sunlight NexVisor clusters for a disaggregated storage architecture. Each 1U Photon appliance contains up to 128TB of storage and can achieve an unprecedented 6m IOPS with under 50 microsecond latency. Appliances are stackable and scale linearly. Photon is fully integrated with the Sunlight Dashboard for easy manageability. Sunlight Photon is the simplest way to access millions of IOPS per fully virtualised guest VM in a disaggregated storage mode.

High performance, low latency

  • 50 microsecond access latency from a NexVisor VM
  • Stackable, with linear scale-out performance

Seamless integration and management

  • Fully integrated into Sunlight Dashboard
  • Control fabric-attached storage volumes alongside VMs from single UI
  • Bring your own NVMe drives - don’t pay inflated proprietary NVMe drive prices

Highly available

  • Configurable fault tolerance to multiple drive failures
  • Power and controller redundancy
  • Ultra-fast repair and resync

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).
