LinkedIn's Open19 Project Aims for New Rack/Server Spec

LinkedIn is launching a new Open19 project that aims to establish a new open standard for servers based on a common form factor.

LinkedIn believes a new spec could lead to lower cost per rack, lower cost per server, and optimized power utilization in its hyperscale, cloud data centers. The project is open and industry participation is welcomed.

The Open19 platform is based on standard building blocks with the following specifications:

  • Standard 19-inch 4 post rack;
  • Brick cage;
  • Brick (B), Double Brick (DB), Double High Brick (DHB);
  • Power shelf—12 volt distribution, OTS power modules;
  • Optional Battery Backup Unit (BBU);
  • Optional Networking switch (ToR);
  • Snap-on power cables/PCB—200-250 watts per brick;
  • Snap-on data cables—up to 100G per brick;
  • Provides linear growth on power and bandwidth based on brick size.
