Deploying Sunlight on-premise

Sunlight can be deployed in your datacentre on-premise. In this section we present the minimum guidelines for deploying a Sunlight cluster and also provide links to some pre-certified platforms from well-known vendors.

The minimal recommended specs for a Sunlight cluster are as follows.

Component Minimum Recommended Units
CPU type Single or dual socket Intel Xeon or AMD Epyc
Number of CPU cores 8 cores or higher
System Memory 64GB or more
Boot device 128GB SSD
VM storage capacity tier 2 x 1TB NVMe or higher capacity
Network interfaces 2 x 10gbit Intel X550 or X540 family NICs


Sunlight strongly recommend utilising 10gbit switch infrastructure for network connectivity to the servers. Redundant switches should be provided if network path high availability is required.
Any 10 gbit switch such as Netgear Prosafe are suitable.

The Sunlight on-premise product runs optimally on Intel architecture servers (Intel Xeon or AMD EPYC processors) with a minimum of 64GB RAM, all flash NVMe storage and dual Intel 10GBit NICs (X550 and X540 family). Most existing or off-the-shelf servers can be configured this way (note the links in the section below on Add-on components). Sunlight performs best in such a configuration since the data and network paths are fully optimised to run virtual workloads with baremetal performance.

Following is a list of new servers from well-known vendors that meet the recommended configuration. For add-on components to existing any-brand servers see the component list at the end of the page.
