Yosemite is a multi-node server chassis open sourced in 2015. It contains four high-powered system-on-a-chip (SoC) processor cards. Each module holds one SoC targeting up to 65W TDP with:

  • Power-efficient Intel D-1500 processor
  • Up to 128GB of DDR4 memory per node
  • At least one local SSD interface

Dimensions are compatible with Open Rack, which can accommodate 12 nodes in 2 OpenU or up to 192 SoC server cards in a single rack.

Winterfell is a chassis that holds three x86 server nodes. It was first open sourced in 2013. Typically contains:

  • Dual socket Intel® C610 series (E5-2600 V3 and V4)
  • Up to 6 2.5″ local SSDs
  • Up to 512GB – 8GB/16GB/32GB DDR4 up to 2133MT/s in 16 DIMM Slots

Dimensions are compatible with Open Rack, which can accommodate 3 nodes in 2 OpenU or 60 nodes in a rack.





Windmill, open sourced in 2012, represents the V2 OCP server. Whilst this machine is optimised for Intel there was also a chassis called Watermark specifically for AMD chip sets.





Launched in 2011, the Freedom server represents the first OCP V1 server. There is no server case so all the components are exposed for easy service especially as no tools are needed for service. This also improves air flow.

  • 60mm fans
  • Tool-less
  • All front cable access
