Sunlight Software-defined Storage (SDS), a component of Sunlight HyperConverged Edge (HCE), aggregates local storage drives across a cluster (ideally NVMe) into a virtual storage pool which can be provisioned as vDisks – each with their own redundancy policies, and fast repair and resynch times for content repair. Sunlight SDS is designed for easy scaling and low latency – supplying over 1M IOPS per VM.

Easy to implement and manage

Sunlight is easy to install - the complete Sunlight HCE 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 HCE stack and is highly-available by design across the cluster.

Easy to implement and manage


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).
