![]() Leaf: Pigeon 1.0 hardware – 3.2T silicon non-blocking topology 1:1 over-subscription to spine.Top of Rack: Pigeon 1.0 hardware – 3.2T silicon 10/25/50/100G server attachment each cabinet: 96 dense compute units.The hardware platform is grounded in Open19, which improves our rack integration through snap-on power and data speeds that are up to 2-3x faster than our current generation of hardware. In our case, that location is the software stack that rides on top of a few standard Linux distributions: A portable control plane that can be run on hosts and routers, anywhere in the fabric, and provides us with the ability to separate hardware scaling from software features. Building a simple fabric, however, does not remove the complexity entirely it simply moves it to another location in the network. This single-SKU data center enables us to move away from the complexity of large chassis-based boxes to a simple singular module that is repeatable and can be increased in quantity as we scale out. We use one hardware design, a 3.2 Tbps pizza-box switch, as the building block for all different tiers of our leaf-and-spine topology that operate on top of one unified software stack. In our recent blog post about Project Altair, we explained our move to a single-SKU data center model, specifically based on the Falco open-switch platform. To accomplish these goals, we are disaggregating our network, separating the hardware and software in a way that allows us to modify and manage the network without intrusive downtime, and moving to a software-driven network architecture. Programmability brings benefits like being able to prioritize traffic distribution, load-balancing, or security posture when needed, on-demand with minimal effort, and also increases agility and responsiveness in delivery. This allows our network operations and site reliability teams to focus on running the network, rather than on managing tools and configurations, and thereby unlocks further innovation. Being able to modify the behavior of the data-center fabric in near real time, without touching device configurations, allows us to tune the operation of the fabric to best fit application and business requirements. To the three dimensions above, we recently added a new one: programmability. Apply RFC1925 Rule 12 to our network and protocols literally: "perfection has been reached not when there is nothing left to add, but when there is nothing left to take away.” Simplicity: Focus on finding the most minimalistic, simple, and modular approaches to infrastructure engineering.Independence: Refuse to develop a dependence on a single vendor or vendor-driven architecture (and hence avoid the inevitable forklift upgrades).Openness: Use community-based tools where possible.The three core principles that have guided our infrastructure design and our strategy are: Adding a new component, a new feature, or a new service without any traffic loss or architectural change is challenging. At LinkedIn, as we scaled our data center network, it became evident that we needed to provision and build networks not only as quickly as possible, but also with the most simple and minimalistic approaches possible - something that previously was not quite apparent to us. Operating a large-scale, rapidly growing network requires a philosophical change in how you plan, deploy, and operate your infrastructure. The build element is overseen by our highly skilled project managers as Prime Integrator, which includes construction management and external contracting teams.More on Infrastructure Live at Interop ITX We’ve commissioned over 50 million square feet of data center space around the world and can manage your entire process, from design through the build to commissioning of the new facility. This ultimately helps you determine availability, reliability, and topology needs, as well as overall data center costs. We provide everything from the conceptual physical data center design to schematic design, detailed design construction documents, and other tools. We’ve designed over 65 million square feet of floor space, and half of all LEED gold and platinum-certified data centers. We provide a detailed design that is customized to meet your specific technology and data center objectives and design each solution to be energy efficient. Trusted hands to create the blueprints for your data center based on your specific needs. Our turnkey services can be the prime integrator and manage the entire solution, or we can collaborate in partnership with a general contractor.
