The Open Compute Project (OCP) is a collaborative, open-source initiative founded by Facebook (now Meta) in 2011 to redesign hardware for data centers, enabling the sharing of efficient, scalable designs among a global community of technology companies, engineers, and researchers.[1]The project originated from Facebook's efforts in 2009 to create a more energy-efficient data center in Prineville, Oregon, which was completed in 2011 and was 38% more energy efficient while reducing operating costs by 24% compared to prior facilities.[1] This success prompted the open-sourcing of designs to accelerate industry-wide innovation, lower costs, and promote sustainability in computing infrastructure.[1] As a non-profit organization, OCP operates on core tenets including efficiency, impact, openness, scalability, and sustainability, requiring contributions to align with at least three of these principles.[2][3]OCP's structure fosters participation through working groups and subprojects focused on key areas such as servers (including general-purpose and GPU-accelerated systems), storage, networking equipment, rack and power systems, data center facilities, hardware management, and emerging domains like open accelerator infrastructure for AI, telecommunications, and edge computing.[1][4] The community shares intellectual property freely, encouraging hardware manufacturers to adapt and produce OCP-compliant products that prioritize modularity and resource efficiency.[1]Since its inception, OCP has grown into an influential force in the hyperscale computing ecosystem, with contributions from major players like Microsoft, Google, and Intel, driving the adoption of open standards that have reduced hardware complexity and environmental impact across global data centers.[1] By 2025, the project continues to evolve, supporting advanced applications in AI and sustainable IT while hosting annual global summits to advance collaborative innovation.[5]
History
Founding and Early Development
The Open Compute Project (OCP) was founded in 2011 by engineers at Facebook (now Meta) to address the challenges of scaling hardware for rapidly growing social media infrastructure, particularly in hyperscale data centers. The initiative stemmed from Facebook's internal efforts starting in 2009 to design an energy-efficient facility in Prineville, Oregon, which became the company's first dedicated data center. This project, completed by 2011 after two years of work by a small team of engineers, achieved significant improvements: a 38% reduction in energy use and 24% less expensive to operate compared to previous facilities, driven by custom optimizations in servers, racks, and cooling systems. The core motivation was to break free from proprietary hardware constraints that limited innovation and increased costs for large-scale deployments.[1][6]On April 7, 2011, Facebook publicly announced OCP at its headquarters in Palo Alto, California, releasing open-source designs for key data center components to foster industry-wide collaboration. These initial contributions included server motherboards optimized for both AMD and Intel CPUs, power supplies, rack architectures, and cooling solutions, all engineered for maximum efficiency without unnecessary branding or aesthetics—a philosophy known as "vanity-free" design. By sharing these specifications under an open license, Facebook aimed to reduce vendor lock-in, lower procurement costs, and accelerate hardware improvements through collective input, enabling any organization to build or adapt the designs. The effort was led by Jonathan Heiliger, Facebook's Vice President of Technical Operations at the time, who envisioned applying open-source software principles to hardware to drive broader ecosystem efficiency.[7][8][9]Early development emphasized partnerships to validate and manufacture the designs, with founding supporters including Intel, Rackspace, Goldman Sachs, and Arista Networks co-founder Andy Bechtolsheim, who helped establish OCP as a nonprofit organization shortly after launch. Quanta Computer, a key original design manufacturer, collaborated on production, while AMD provided processors for initial motherboard variants, ensuring compatibility and real-world testing. These alliances underscored OCP's community-driven approach, prioritizing shared intellectual property over competition. The project codified core principles—openness, efficiency, scalability, impact, and sustainability—to guide contributions, requiring all designs to align with at least three of these tenets for acceptance. This foundation laid the groundwork for ongoing collaboration, and later collaborated with the Linux Foundation on hardware-software co-design.[10][8][1]
Key Milestones and Evolution
Following its founding by Facebook in 2011 to open-source efficient data center hardware designs, the Open Compute Project (OCP) underwent significant organizational evolution in the ensuing years. In 2013, OCP formalized its status as an independent 501(c)(6) non-profit organization, enabling broader industry participation beyond the initial hyperscale contributors and fostering collaborative governance through a board of directors comprising founding members like Intel, Rackspace, and others.[10][11]A pivotal expansion occurred with the launch of new project categories to address diverse infrastructure needs. The Open Vault storage project was introduced in 2012, focusing on modular, high-density storage systems to optimize data management in large-scale environments. This was followed by the Networking Project in 2013, which aimed to disaggregate network hardware and promote open-source switch designs, marking OCP's entry into connectivity solutions and attracting contributions from telecom operators.[12][13]Entering the 2020s, OCP shifted emphasis toward sustainability and artificial intelligence (AI), aligning with global demands for energy-efficient and scalable computing. In 2022, OCP established Sustainability as a core tenet, including efforts on circular economy practices to repurpose hyperscale hardware and reduce e-waste emissions, while the 2021 OCP Future Technologies Initiative formalized efforts to integrate AI-specific hardware innovations, such as advanced accelerators and rack-scale designs. Complementing this, the OCP Experience Center was inaugurated in November 2021 as the first North American testing facility, providing a collaborative space for validating OCP-compliant prototypes and accelerating adoption of sustainable technologies. In 2025, OCP hosted its Global Summit emphasizing AI advancements and added AMD, Arm, and NVIDIA to its board.[10][14][15][16]Membership growth reflected OCP's expanding influence, evolving from a core group of hyperscalers to a diverse ecosystem encompassing cloud providers, semiconductor companies, and edge infrastructure firms. By late 2024, OCP had grown to over 400 member organizations, with more than 5,000 engineers contributing to projects that drive IT industry spending on OCP designs reaching $41 billion in 2024 (as of October 2024).[17]
Organization and Governance
Structure and Leadership
The Open Compute Project is governed by the Open Compute Project Foundation, a nonprofit entity that oversees community activities, intellectual property management, and strategic direction.[18] The Foundation maintains an independent structure while collaborating with organizations like the Linux Foundation to promote hardware-software integration in open infrastructure.[19] A Board of Directors, drawn from contributing member companies, holds ultimate authority for approving top-level projects and appointing key committee leaders.[18] As of February 2025, David Ramku serves as Board Chair, with the board expanded in October 2025 to include representatives from AMD, Arm, and NVIDIA for enhanced leadership in emerging technologies.[20][16]At the Foundation level, leadership includes the Chief Executive Officer, currently George Tchaparian as of 2025, who directs operations, innovation initiatives, and community engagement.[21] Supporting roles encompass the Chief Innovation Officer (Cliff Grossner), Chief Technology Officer (Zane Ball), and others focused on technical and administrative functions.[21] Within the technical domains—such as compute, storage, networking, and power—domain-specific committees are led by Project Leads elected by their respective communities, who coordinate sub-projects and ensure alignment with OCP principles.[18] The overarching SteeringCommittee, consisting of one representative per project plus three co-chairs appointed by the Foundation for two-year terms, evaluates strategic proposals, reviews contributions, and facilitates decision-making across all areas.[18]OCP's projects follow a tiered structure to standardize development and adoption of specifications. New ideas enter the Incubation phase, where communities build support, establish governance, create repositories (e.g., on GitHub), and demonstrate initial contributions from at least one corporate member while adhering to four of five core tenets: efficiency, impact, openness, scalability, and sustainability.[4][18] Successful incubation leads to the Accepted phase (also termed Impact), reserved for self-sustaining efforts with defined charters, regular community meetings, and production-ready outputs backed by contributions from at least two corporate members.[4][18] Throughout, the Community Review process—conducted by Project Leads and the Steering Committee—assesses specifications for technical merit, interoperability, and compliance before formal acceptance, typically within 12 months of incubation.[4][18]Contributions occur through an accessible, collaborative process designed to encourage broad participation. Proposers submit designs, specifications, or prototypes via the OCP Contribution Portal, first signing an Open Web Foundation Contributor License Agreement (OWF CLA) to grant necessary rights while retaining IP ownership.[22][23] Accepted materials are licensed openly: hardware designs typically under Creative Commons Attribution 4.0 (CC-BY 4.0), and software under OSI-approved licenses such as the BSD license, ensuring free reuse, modification, and distribution.[24][25] Community voting, facilitated by technical committees and the Steering Committee, determines acceptance based on alignment with OCP tenets and peer review feedback, promoting merit-based evolution of standards.[22][18]
Membership and Community Engagement
The Open Compute Project (OCP) offers multiple membership tiers to facilitate participation from individuals and organizations, with benefits scaling based on commitment level. Individual membership is free and open to anyone by signing a simple agreement, allowing participation in community discussions and access to resources without financial obligation.[26] Corporate tiers include the Startup program (on demand pricing for early-stage companies), Community (formerly known as Bronze starting January 2026, at $5,000 annually), Silver ($25,000), Gold ($40,000), and Platinum ($50,000). These tiers provide escalating perks, such as logo usage rights for branding, voting privileges in project decisions (0 votes for Community and Startup, 1 for Silver, 2 for Gold, and 3 for Platinum), eligibility for volunteer leadership roles (up to 25% representation at Platinum), and discounts on summit sponsorships (up to 15% at Platinum).[27][28]Community engagement extends beyond membership through diverse activities that foster collaboration and knowledge sharing. Regional chapters operate in areas like Asia-Pacific, China, Europe, Japan, Korea, and Taiwan, hosting local events to adapt OCP principles to regional needs and promote adoption. Hackathons, often held at summits, encourage innovative problem-solving; for example, the 2023 Global Summit Hackathon and Edge-Native AI Hackathon brought together developers from organizations like Linux Foundation Edge and ETSI to prototype edge computing solutions. The OCP Academy, launched in October 2025 on the Docebo platform, offers free online courses, webinars, and modules on topics like data center design and sustainability, aiming to educate thousands of engineers globally.[29][30][31][32]Key tools enable ongoing contributions and interaction within the OCP ecosystem. The project's GitHub organization hosts over 150 repositories where members submit specifications, designs, and code under open licenses, supporting collaborative development across workstreams. Forums and mailing lists, such as the OCP-All groups.io list, facilitate discussions on technical and strategic topics, with thousands of engineers actively participating. Annual Global Summits serve as flagship events for networking and announcements; the 2025 summit in San Jose, California (October 13-16), drew over 10,000 attendees and emphasized AI infrastructure innovations.[33]OCP's participant diversity reflects its broad appeal, encompassing hyperscalers like Meta and Microsoft, which drive large-scale deployments; original equipment manufacturers (OEMs) such as Dell and HPE, contributing to hardwarestandardization; and startups via the dedicated program, which provides mentorship and event access to accelerate innovation. This mix ensures a balanced ecosystem where over 400 member organizations and 5,000 engineers collaborate on efficient, sustainable data center technologies.[34][35][17]
Technical Specifications and Projects
Compute and Server Designs
The Open Compute Project (OCP) emphasizes modular and efficient hardware designs for compute and server systems, enabling hyperscale data centers to scale cost-effectively while minimizing environmental impact. These designs prioritize open specifications that allow for interchangeable components, reducing dependency on proprietaryhardware and facilitating rapid innovation across the ecosystem. Core to this approach is the development of standardized form factors and interfaces that support high-performance computing workloads, with a focus on CPU-based servers and accelerator integrations.Server Motherboard (SMB) specifications within OCP are defined under the Datacenter Modular Hardware System (DC-MHS), which provides a flexible framework for multi-node servers in modern data centers. These motherboards support 2U and 4U form factors, accommodating single or dual-socket configurations for Intel and AMD CPUs, such as AMD EPYC or Intel Xeon processors. For instance, the PEGATRON MBH00-1T1SP DC-MHS Server Motherboard follows OCP DC-MHS guidelines, enabling modular integration with 48V power systems and peripheral expansions like risers for enhanced I/O connectivity. This standardization allows for easier upgrades and maintenance in dense rack environments.[36][37][38]OCP promotes modular compute racks through initiatives like Open Vault and OpenRack versions, which facilitate easy hardware upgrades without full system overhauls. Open Vault, originally contributed by Facebook, is a 2U chassis design optimized for high-density configurations, supporting up to 30 drive bays while integrating with compute modules for scalable deployments. Complementary to this, OpenRack V2 and V3 specifications enable modular sleds and trays that house SMBs and other components, allowing operators to swap processors or memory independently to adapt to evolving workloads. These racks emphasize tool-less assembly and hot-swappable elements to minimize downtime in hyperscale operations.[39]The Accelerator Module (OAM) addresses the growing demands of AI and machine learning by providing a standardized mezzanineform factor for GPUs, TPUs, and other accelerators. Introduced in OAM 1.0 in 2018, it defines mechanical, electrical, and thermal interfaces for integration with universal baseboards, supporting PCIe and OAM-specific interconnects for heterogeneous computing. Subsequent updates, such as OAM 1.5, enhance support for AI workloads with improved liquid cooling options and higher bandwidth, enabling up to 400Gbps fabric connectivity for distributed training. This modularity allows seamless attachment to SMBs, accelerating inference and training tasks in OCP-compliant servers.[40]Overall, OCP compute and server designs aim to achieve significant efficiency gains, with early implementations delivering up to 38% better energy efficiency compared to proprietary alternatives through optimized power delivery and component sharing. This standardization supports hyperscale deployments by lowering total cost of ownership and enabling rapid prototyping across vendors. Brief integration with OCP power systems, such as 48V distribution, further enhances these benefits without altering core compute architectures.[7]
Storage and Data Management
The Open Compute Project (OCP) Storage Project develops open specifications for storage hardware and systems tailored to hyperscale data centers, emphasizing modularity, high density, and interoperability to reduce costs and improve scalability.[41] Key contributions include chassis designs that support mixed-drive environments and high-performance interfaces, enabling efficient data management without proprietary lock-in. These specifications address the growing demands for petabyte-scale storage by prioritizing serviceability and power efficiency in rack-scale deployments.[42]A cornerstone of OCP storage designs is the Open Vault, a 2U just a bunch of disks (JBOD) chassis that provides high-density storage with support for mixing hard disk drives (HDDs) and solid-state drives (SSDs).[43] The Open Vault accommodates up to 30 drives in a modular configuration, utilizing a flexible I/O topology that connects to any compatible host server via standard interfaces like SAS or PCIe.[44] This design facilitates easy expansion and compatibility across OCP ecosystems, with dual trays allowing independent access for maintenance.[43]For high-performance applications, OCP specifies NVMe-based storage modules, such as the Lightning platform, which extends the Open Vault concept to all-flash environments using PCIe Gen3 links.[45] Lightning supports up to 60 NVMe SSDs per tray, delivering low-latency access with P99 read latencies as low as 1,500 µs in cloud-optimized configurations, while maintaining power efficiency under 10W average per drive.[46] These modules adhere to the OCP NVMe Cloud SSD Specification, which mandates features like hot-swappable operation, queue depths of at least 1,024, and endurance ratings exceeding 7 years under continuous power, ensuring reliability for demanding workloads.[46]Data management in OCP storage nodes relies on open-source firmware solutions like OpenBMC, which provides unified baseboard management for telemetry, monitoring, and control.[45] In Lightning deployments, OpenBMC enables real-time telemetry via NVMe-MI interfaces, capturing SSD metrics such as temperature, error counts, and event logs, while supporting firmware updates over I2C and PCIe without system downtime.[45] This integration allows for automated fan control and health monitoring across storage arrays, reducing operational overhead in large-scale environments.[45]Efficiency in OCP storage designs is enhanced through features like hot-swappable drives at any mounting position and minimized cabling, which streamline servicing and lower latency by enabling direct host-to-drive connections.[44] For instance, the Open Vault's reduced internal wiring supports faster signal integrity over longer distances, contributing to overall system densities of 30 drives per 2U.[43] These optimizations, validated in hyperscale testing, prioritize total cost of ownership by balancing performance with simplified infrastructure.[47]
Networking and Optics
The Open Compute Project (OCP) Networking subproject develops open specifications for disaggregated data center networking hardware, emphasizing modularity, interoperability, and efficiency to support hyperscale environments.[48] This includes hardware designs for switches and optical interconnects that enable high-bandwidth, low-latency fabrics, particularly for Ethernet-based topologies. Optics efforts focus on standardized pluggable transceivers to reduce costs and improve scalability in dense wavelength-division multiplexing (DWDM) systems.[49]A foundational component of OCP networking is the Open Network Install Environment (ONIE), a lightweight operating system pre-installed as firmware on bare-metal network switches.[50] Developed initially by Cumulus Networks in 2012 and adopted by OCP in 2013, ONIE enables automated provisioning of any compatible network operating system (NOS), such as SONiC or Open Network Linux, without vendor lock-in.[50] It supports bare-metal hardware ecosystems by standardizing the installation process across diverse switch architectures, including x86, ARM, and PowerPC CPUs, thereby reducing SKU complexity for manufacturers and facilitating rapid deployment in large-scale data centers.[50] ONIE operates in a minimal mode for OS discovery and installation via protocols like DHCP and TFTP, ensuring secure boot options and compatibility with software-defined networking (SDN) stacks.[51]OCP switch designs, such as the Wedge and Minipack series contributed by Meta (formerly Facebook), provide open hardware platforms for high-radix Ethernet switching optimized for AI and cloud workloads. The Wedge family, starting with the original Wedge-100 in 2014, evolved to support 100G Ethernet with models like the Wedge 100C (32x100G ports using Broadcom Trident 3 ASIC) and Wedge 100S (32x100G ports).[52] Later iterations, including the Wedge 400 introduced in 2021, feature a 2RU form factor with 16x400G QSFP-DD uplinks and 32x200G QSFP56 downlinks, delivering 12.8 Tbps switching capacity via Broadcom Tomahawk 3 or Cisco Silicon One ASICs.[53] These designs emphasize modular daughter cards for flexibility, allowing backward compatibility with 100G optics while enabling upgrades to 400G for AI fabrics that require low-latency, non-blocking connectivity in top-of-rack (ToR) deployments.[54]The Minipack series extends this modularity for spine-level switching in dense fabrics, with the Minipack2 specification (shared in 2021) supporting 128x200G QSFP56 ports for 25.6 Tbps throughput using Broadcom Tomahawk 4 ASIC.[55] It offers backward compatibility to 128x100G QSFP28 and forward compatibility to 64x400G QSFP-DD, making it suitable for high-scale AI environments like Meta's F16 data center fabric.[55] These switches integrate with OCP's broader ecosystem, including ONIE for OS installation, to support Ethernet-based AI interconnects that handle massive parallel processing without proprietary constraints.[56]OCP's optics specifications standardize pluggable transceivers for efficient short-reach data center links, with contributions like the CWDM4-OCP (2017) defining 100G modules optimized for multimode fiber up to 2 km.[57] More recent specs include the 200G FR4 QSFP56 (2020) for single-mode fiber at 2 km and the 400G FR4 QSFP-DD (2021) supporting 500 m reaches with four 100G lambda channels.[58][49] These align with MSA standards but incorporate OCP tenets for power efficiency and interoperability. In collaboration with the Telecom Infra Project (TIP), OCP supports the Open Optical Packet Transport (OOPT) framework, which defines open interfaces for pluggable transceivers in disaggregated optical networks, enabling multi-vendor DWDM deployments for packet transport.[59] OOPT emphasizes modular optics like coherent pluggables to lower costs in edge and core transport scenarios.[60]In 2025, OCP launched the Ethernet for Scale-Up Networking (ESUN) initiative to address AI-specific challenges in single-rack or multi-rack scale-up topologies (as of October 2025). Announced on October 13, 2025, at the OCP Global Summit, ESUN—led by contributors including Meta, NVIDIA, and Microsoft—focuses on developing lossless L2/L3 Ethernet standards for high-bandwidth, low-jitter interconnects aligned with IEEE 802.3 and UEC guidelines.[61] It targets endpoint functionality for AI clusters, building on existing 100G/400G+ infrastructures to enable robust, interoperable fabrics for GPU-direct communications in scale-up AI workloads.[62]
Power, Cooling, and Rack Infrastructure
The Open Rack Version 3 (ORv3) represents a significant evolution in OCP's rack infrastructure, designed to accommodate higher densities and enhanced resilience in data centers. It features a wider frame, typically 600 mm (approximately 23.6 inches) externally, to support 21-inch IT equipment mounting alongside traditional 19-inch options, enabling denser server packing compared to standard EIA-310 racks by allowing more components per unit without compromising airflow or cabling. This design facilitates up to 30 kW power density per rack while integrating provisions for liquid cooling manifolds and busbars. Additionally, ORv3 incorporates seismic resilience through robust leveling feet capable of supporting a fully loaded rack (up to 1,500 kg) under seismic loads, including a required 10-degree tilt test for 1 minute to ensure stability in earthquake-prone regions. These specifications are outlined in the official OCP Open Rack Base Specification Version 3, promoting interoperability across vendors like Rittal and Eaton.[63][64]Power distribution within OCP infrastructure emphasizes disaggregated and efficient architectures, exemplified by the Mt. Diablo project, a 2024 collaboration between Meta, Google, and Microsoft to standardize high-density power delivery for AI workloads. Mt. Diablo introduces a modular power shelf in a dedicated "sidecar" rack adjacent to the IT rack, separating power conversion from compute to support densities exceeding 100 kW per rack while optimizing space and efficiency. The design delivers power via standardized 48V DC busbars to IT equipment, with onboard conversion to 12V or lower for components, reducing conversion losses and enabling scalability to 400V DC for future megawatt-scale racks. This disaggregated approach enhances maintainability by isolating power failures from compute nodes, as detailed in Microsoft's technical overview and OCP contributions.[65][66]OCP's cooling innovations prioritize liquid-based solutions to manage escalating thermal loads, with the Immersion Project standardizing two-phase immersion cooling where servers are submerged in dielectric fluids that boil at low temperatures to absorb heat efficiently, enabling waste heat reuse and interoperability across systems. Complementing this, direct-to-chip liquid cooling employs cold plates attached to high-heat components like CPUs and GPUs, circulating single- or two-phase refrigerants to transfer heat directly, often achieving a Power Usage Effectiveness (PUE) below 1.1 by minimizing air cooling overhead and fan power. These methods, developed through OCP's Cooling Environments initiative, support rack-level integration with ORv3 manifolds for coolant distribution, as specified in project guidelines and whitepapers.[67]Efficiency in OCP power systems is bolstered by redundant architectures, such as N+1 or 2N configurations in power shelves and battery backup units (BBUs), which incorporate dual feeds, hot-swappable modules, and uninterruptible power supplies to maintain operations during failures. These designs achieve five-nines (99.999%) availability, equating to less than 5.26 minutes of annual downtime, by isolating faults and enabling seamless failover, as demonstrated in Google's +/-400V DC implementations and OCP BBU specifications. Such redundancy integrates briefly with compute hardware for overall system reliability without introducing single points of failure.[66][68]
Emerging Technologies for AI and Sustainability
The Open Compute Project (OCP) has advanced its Open Chiplet Economy in 2025 through key contributions aimed at enabling modular, scalable silicon designs for AI and high-performance computing (HPC). This expansion promotes interoperability among chiplet vendors by standardizing interfaces and architectures, fostering a diverse ecosystem for AI accelerators. A pivotal development is the Foundation Chiplet System Architecture (FCSA), contributed by Arm, which provides a specification for system partitioning and chiplet connectivity to reduce fragmentation in heterogeneous integration.[69][70] Complementing FCSA, the Bunch of Wires 2.0 (BoW 2.0) specification enhances die-to-die interfaces for memory-intensive AI and HPC workloads, supporting high-bandwidth, low-latency connections with defined operating modes, signal ordering, and electrical requirements.[70][71] These efforts build on the OCP's upstream work in chiplet selection and integration, accelerating innovation in disaggregated compute systems.[72]For AI-specific hardware, OCP has developed modules that support composable silicon architectures, allowing flexible assembly of accelerators for diverse workloads. The Open Accelerator Module (OAM), part of the Open Accelerator Infrastructure (OAI) subproject, defines a standardized form factor and interconnect for compute accelerators, enabling up to 700W TDP in 48V configurations and compatibility with multiple ASICs.[73][74] OAM facilitates composable designs by integrating with universal baseboards and expansion modules, optimizing scalability for AIinference and training.[75] In parallel, OCP initiatives address AItraining fabrics through open Ethernet-based architectures, including polymorphic designs that scale out GPU connectivity for large clusters.[76] These fabrics incorporate non-scheduled and scheduled Ethernet protocols to manage workload diversity, enhancing efficiency in collective operations for AI-ML tasks.[77][78]OCP's sustainability projects emphasize guidelines for integrating renewable energy and achieving carbon-neutral data centers, aligning with broader industry goals for net-zero emissions. The OCPSustainability Project focuses on minimizing greenhouse gas impacts through metrics for energy use, water consumption, and material circularity, while the Data Center Facility (DCF) Sustainability subproject targets non-IT decarbonization via power distribution and facility designs.[79][80][81] In 2025, OCP released a taxonomy for carbon disclosure in collaboration with the Infrastructure Masons Climate Accord (as of October 2025), establishing a framework for reporting equipment impacts to support renewable sourcing and offset strategies.[82] These efforts integrate with OCP's testing and validation programs, including OCP Ready certifications for facilities, to verify sustainable practices in real-world deployments.[83][84]In 2025, OCP collaborations have targeted advanced cooling solutions for AI clusters to address escalating power densities. Partnerships, including those showcased at the OCP Global Summit (as of October 2025), advance liquid cooling standards like Advanced Cooling Environments (ACF) and direct-to-chip distributions, enabling support for high-density racks up to 1 MW.[78][66] These initiatives, involving contributors like Microsoft and Google, aim to reduce energy consumption in AI inference workloads through optimized thermal management and efficient coolant units, contributing to overall data center efficiency gains.[85][86]

Adopters report operational cost reductions, exemplified by Meta's 24% savings in data center running expenses due to optimized power usage and modular components.[87] These efficiencies also drive broader market impacts, with OCP server sales growing at a 35.7% compound annual growth rate (CAGR) and peripherals at 51% CAGR through 2028, enabling smaller operators to access hyperscale innovations without proprietary lock-in.[90]In edge computing and telecommunications, OCP designs facilitate deployments requiring compact, low-power infrastructure for distributed environments. The OCP Telecom & Edge project specifies solutions like cell site gateways and open radio units, adopted by telecom operators to support 5G edge processing and reduce latency in remote locations.[91] For instance, these standards enable efficient integration of compute resources at network edges, aligning with industry needs for scalable, energy-efficient hardware in telecom infrastructure.[92]
Recent Initiatives and Partnerships
In 2025, the Open Compute Project (OCP) Global Summit highlighted significant advancements in AI infrastructure, including the launch of the Ethernet for Scale-Up Networking (ESUN) project. ESUN aims to develop Ethernet-based technologies optimized for large-scale AI clusters, enabling efficient scale-up networking to support high-performance computing demands.[61] The summit also featured expansions to the Open Chiplet Economy, building on the 2024 Chiplet Marketplace launch by introducing new standards and tools for modular chip design, fostering silicon diversity in AI systems.[70]OCP forged key partnerships in 2025 to address AI-driven challenges across storage, cooling, and interoperability. In October, OCP collaborated with the Storage Networking Industry Association (SNIA) to standardize solutions for AI storage, memory, and networking, promoting open ecosystems to optimize hyperscale data center performance.[93] Similarly, a new alliance with the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) focused on advancing data center cooling technologies, aligning OCP designs with ASHRAE's environmental guidelines to improve energy efficiency.[94] Additionally, OCP partnered with the Open Interchange (OIX) to create a unified open standard harmonizing OIX-2 data center protocols with OCP's interoperability frameworks, enhancing network interconnection in multi-vendor environments.[95]Post-2020 initiatives have included educational efforts to build community expertise, such as the OCP Future Technologies Initiative launched in 2021, which integrates academic and research contributions into open source projects.[14] In parallel, the 2024 Mt. Diablo project, co-developed by Meta, Google, and Microsoft, introduced disaggregated power architectures for AI racks, supporting up to 1 MW per rack through 400V systems and solid-state transformers to enable scalable, efficient power delivery.[96]Looking ahead, OCP is developing AI cluster guidelines through projects like Open Cluster Designs for AI, which provide procurement-ready specifications for scale-up and scale-out configurations to accelerate multi-vendor deployments.[97] On sustainability, the OCP Sustainability Project advances supply chain transparency via a 2025 taxonomy for carbon disclosure, co-developed with iMasons, to standardize reporting and reduce audit redundancies for environmental impact assessments.[98]
Legal Matters
Litigation and Intellectual Property Disputes
One notable early legal challenge to the Open Compute Project (OCP) arose in 2012 when Yahoo accused Facebook of infringing 16 patents related to data center and server technologies, specifically claiming that designs shared through OCP violated Yahoo's intellectual property rights.[99] This assertion was part of a broader patent dispute initiated by Yahoo in March 2012, which encompassed advertising and privacy technologies but extended to OCP's open-sourced hardware specifications.[100] The parties settled the suits in July 2012 without monetary exchange, instead forming a cross-licensing agreement and advertising partnership to resolve all claims.[101]In 2015, British firm BladeRoom Group filed a lawsuit against Facebook in the U.S. District Court for the Northern District of California, alleging misappropriation of trade secrets in modular data center designs developed during failed partnership talks.[102] BladeRoom claimed Facebook improperly disclosed its proprietary cooling and construction methodologies through OCP publications, including a blog post and specifications, thereby undermining BladeRoom's commercial exclusivity and causing damages estimated at over $365 million.[103] The case advanced past Facebook's motion to dismiss in 2017, but settled confidentially in April 2018, with BladeRoom dropping claims against Facebook while proceeding against co-defendant Emerson Network Power.[104]To address such patent and trade secret risks inherent in open hardware collaboration, OCP established its Intellectual Property Rights Management Policy, which requires contributors to grant royalty-free, perpetual licenses under the Open Web Foundation Contributor License Agreement (CLA) for essential patents covering specifications.[105] This policy includes a 30-day opt-out period for excluding specific patent claims via detailed notices, ensuring mutual protection while promoting adoption; final specifications are licensed under the Open Web Foundation Agreement for non-exclusive, royalty-free use.[105] These mechanisms function defensively by networking IP commitments among participants, deterring litigation through reciprocal licensing and clarifying rights for implementations.These disputes underscored vulnerabilities in OCP's open-source model, where sharing innovations invites infringement claims, yet they reinforced the value of robust licensing frameworks in mitigating legal risks and fostering sustained hardware innovation within the community.[105]
