LinkedIn pushes ahead with Open19 in its data centers

In a blog post, LinkedIn's engineering team announced that it working to deploy its Open19 technology in its data centers.

The Open19 project, which LinkedIn launched in July 2016, aims to establish a new open standard for servers based on a common form factor. The Open19 platform is based on the standard 19-inch, four post rack used in data centers.

According to the blog post, since adopting Open 19, LinkedIn experienced a 7X improvement in rack integration and an ability to install 4X the number of servers per rack.

LinkedIn also announced that it has become a Platinum member of the Open Compute Project (OCP).

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:

LinkedIn Inaugurates Hyperscale Data Center in Oregon

LinkedIn opened a massively scalable, next-generation data center in Oregon.

The facility, which is hosted by Infomart, is now fully live and ramped. The location benefits from a direct access contract for 100% renewable energy, network diversity, expansion capabilities, and talent opportunities. LinkedIn expects to achieve a PUE (Power Usage Effectiveness) of 1.06 during full economization mode.

The network in the new data center uses LinkedIn's own programmable switch design (Pigeon) based on Broadcom's Tomahawk silicon and its own software stack.

LinkedIn Develops its Own Data Center Switch

LinkedIn's engineering team has developed its own data center switch to keep up with the rapidly growing traffic demands of its professional, social network.

The new switch, dubbed "Pigeon", is a 3.2 Tbps switching platform that can be used as a leaf or spine switch. It uses Broadcom's latest Tomahawk silicon (32X100G) and switch software developed in house.

In a blog post, Zaid Ali Kahn describes why the company decided to take on the difficult task of switching software code development rather than relying on an existing network equipment supplier. Key reason include ongoing bugs, unneeded features, lack of a Linux-based platform support tools such as Chef/Puppet/CFEngine, out-of-date monitoring capabilities, and the high-cost of scaling the software license.

The Pigeon switch will be deployed in LinkedIn's upcoming data center in Oregon.

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.
