“Back in 2009 Facebook seized the opportunity to create what it termed the ‘vanity free’ server with less features to save cost, but more importantly improve reliability and logistics by omitting the parts you don’t need to combine weight reduction with improved energy efficiencies.”

The Open Compute Project’s (OCP) CTO Bill Carter is reflecting on a series of events, triggered by Facebook’s exponential growth, which led to the social media giant designing the world’s most efficient data centre after a small team of engineers spent two years building one from the ground up: software, servers, racks, power supplies, and cooling.

“These servers were designed for large scale outs. 10 years ago, Google, Microsoft and Facebook were all scaling up and making a huge impact on the data centre footprint so it made sense for them to do this. Facebook realised early on the differentiation was in their application and social media app, not as a hardware supplier. What’s not talked about is that the innovation within these servers had become stagnant. Reference designs came from Intel and those designs were duplicated by all the ODMs. If you create an open source society, as happened with software, the belief is you can drive innovation. More people looking at a software problem creates derivative work off these hardware products and vice versa. It can spread like wildfire in the right circumstances. That’s what Facebook wanted to create and was part of the genesis for the Open Compute Project.”

The result now stands in Prineville, Oregon. It was 38% more energy efficient to build and 24% less expensive to run than the company’s previous facilities – and has proved the catalyst for even greater innovation. In 2011, Facebook shared its designs with the public and – along with Intel and Rackspace, Goldman Sachs and Andy Bechtolsheim – launched the Open Compute Project and incorporated the Open Compute Project Foundation. The five members hoped to create a movement in the hardware space that would bring about the same kind of creativity and collaboration we see in open source software.


After spending 33 years working for Intel as a systems architect, and as the company’s OCP liaison in the early days, Carter joined the foundation to get involved with its work on operational efficiency on the facilities side of the business. “We’ve tried to promote collaboration in the data centre construction industry with the focused intent of driving innovation and embracing areas of technology we think we can accelerate and improve upon,” he maintains. “Technologies that have traditionally been controlled and managed by a standards organisation, but they tend to move pretty slow with consensus building. We’ve been able to move faster by enhancing direct communication between the hyperscale end users that drive the business providing the financial means, and the innovation of technology providers.”

Carter recalls with the traditional model you had a OEM or ODM (such as Dell, IBM or HP) that gathered all of that technology together and turned it into a project. They had control over that conversion and what technology actually made it to the marketplace.

“Now we provide a means for these technology providers to collaborate more directly with end users,” he says, adding that the one area of innovation, constant since OCP’s inception, is around energy and efficiency where its keen to push the envelope with new initiatives.

“The traditional data centre brings in power routed out to the physical racks connected to the servers,” explains Carter. “Each of these servers has a redundant power supply so they usually have two power sources with two cords fed to those sometimes from two different utilities in the area to provide that resiliency. You can have up to 80 servers in a rack of equipment, so you have a lot of duplication, and the problem with that 1+1 resiliency model (where you have a hot spare for back up) is that at any given time, each supply is only going to run 50% of its output which is not very efficient. In the very first Facebook design, which they called the Open Rack, they took all of the power supplies out of the server and into a power shelf in the rack and powered that via a higher voltage input power – they did one conversion to 12v and then bussed that across. Architecturally, that conversion from 480v achieved in excess of 90% efficiency which alone saved energy and eliminated all of the power supply elements in the server, reducing cost while allowing further serviceability of the compute node/storage node, so when you refreshed your IT equipment you were disposing of less hardware and only recycling the server board inside.”

To meet the goals of open source, collaborations and partnerships are paramount. A key one for OCP is with the Telecom Infra Project (TIP) – an open source hardware consortium focused on optical broadband networks and open cellular networks. “Much like OCP it works collaboratively with telecoms operators around the world,” reveals Carter. “We have an active networking focus at OCP. Telecom operators are providing universal Customer Premise Equipment (CPE): network access devices that would sit in a small business providing it with a set of access services, a bit like a set top box in your home. Rather than having every carrier design a custom CPE device, the industry saw an opportunity to create a generic device with standardised software that sits on top of that device. We’ve partnered to co-develop this architecture for CPE and develop the hardware Universal Customer Premise (UCP) equipment. We’re working on specs for a small portfolio of products.”

Assessing trends in the data centre industry, Cartner notes, on the networking side, most solutions are built with commodity silicon, which is now being used in all devices, branded or white box solutions. As a result, the tech is available to the consumer regardless of purchase option, so there are no disadvantages by choice. “Companies such as Cumulus Networks and Barefoot have emerged to provide solutions,” he adds. “They are taking open source hardware and qualifying an open source Linux-based network OS on top of it and building the data plate, control and orchestration software on top of that. You really can get a turnkey solution as the barriers to adoption are dissolving. Case in point, Edgecore is a white box provider, and significant contributor to tech at OCP, that recently announced a 400gb switch – one of the first available in the market.”

One of the OCP’s biggest successes to date has been in the field of rack architecture. “We have an Open Rack standard with products built off of 19” EIA3 compatible tech and contributions from Microsoft with the Olympus rack design,” highlights Carter. “Both of these have multi-sourced supply chains behind them. We’re giving the industry efficient choices and are proud to have changed the landscape for networks. For the past eight years working with Facebook and the ODM community we have disaggregated the network switch. Nowadays you can buy any flavour you need – there are multiple options for network OS and all open sourced. That’s a game changer we’ve been part of in developing pathways for these companies to collaborate – we’re not a provider but a true enabler.”

Its success was recently measured when OCP engaged IHS Markit, a world leader in critical information, analytics and solutions, to help validate the adoption of OCP gear across the data centre industry. Since inception, OCP has worked to drive innovation in the data centre industry, bringing together nearly 200 member organisations and more than 4,000 engineers. The demands on the modern data centre continue to expand with the growth of IoT, security and edge computing, as well as increasing energy consumption requirements. This has seen revenue generated from OCP approved equipment in 2017 reached $1.2bn from non-board member companies. OCP board member companies (such as Facebook and Microsoft) have widely adopted OCP principles with great success, however until now it wasn’t clear how far beyond these market leaders that OCP had reached. Carter is impressed that the results of the IHS Markit study forecast OCP adoption among non-board member companies set to surpass $6bn by 2021. Primary drivers for this are power efficiency, cost reductions, standardisation and quick deployment capability across more than 100 OCP developed products.

Until now most of the revenue derived from OCP gear has come from North America, but going forward Carter sees most of its growth opportunity in Asia and Europe as awareness of its work is raised through events like this year’s OCP European summit in Amsterdam, due to take place October 1st and 2nd. Events like these offer a chance for OCP to grow and share ideas around transformation. “Our data centre facilities group aims to drive new standards for colo providers to enhance energy efficiency and draws on the expertise of our European members,” confirms Carter.

What are the OCP’s goals for 2018 and beyond? “We would like to encourage data centres to adopt preparation recommendations to allow them to use this more efficient equipment,” Carter asserts. “We’re also working on hardware management – we have a profile based on the Redfish specification and want to roll that out across our products so that, regardless of where it comes from, if a product meets the OCP spec it can be managed correctly, which will allow the software community to have a universal hardware target they can better design orchestration software for.”

Concluding with an eye on sustainability, Carter believes embedded software is key to producing a complete open source solution. “When equipment is recycled you have to have the ability to maintain it down the road. Often, the BIOS becomes obsolete so if there’s a way for that to be open sourced the community can maintain it and extend the useful life of hardware. What’s useful for a hyperscaler today may be useful to a local cloud provider in the future if we can provide the necessary tools.”

Tech companies profits reach more than US$50bn combined

3 min
Tech giants Apple, Microsoft, and Google's parent company Alphabet have seen a surge in revenue due to the pandemic but also easing of lockdowns

Three tech companies, Apple, Microsoft, and Google owner Alphabet, have reported combined profits of more than US$50 billion in the April-June quarter, showing the impact and importance they have had during the pandemic. 

Although these companies make their money in different ways, the results come amid an increase in consumer demand as the coronavirus pandemic continues to accelerate a trend toward working, shopping, socialising, and more online.

The three companies currently have a combined market value of $6.4 trillion, more than double their value by market capitalisation when the pandemic started 16 months ago. The strong quarterly results served as another reminder of why government regulators are growing increasingly concerned about whether they have become too powerful.




After continually growing revenue in several quarters, Google's parent company Alphabet announced that it made US$61.9 billion in Q2 2021. A jump of 62% from the same period last year, when the organisation's revenue dipped due to the onset of the pandemic. Last quarter, Alphabet posted $55.3 billion in revenue.

Powered by Google, Alphabet earned $18.53 billion, or $27.26 per share, during the quarter, a nearly threefold increase from last year’s earnings of $6.96 billion, or $10.13 per share. Google’s advertising revenue soared 69% to $50.44 billion thanks to what CEO Sundar Pichai called a “rising tide” of online activity among consumers and businesses.

Retail, along with travel and entertainment ads, were the biggest contributors to the revenue increase, the company said. Total revenue surged 62% from last year to $61.88 billion. Revenue after subtracting TAC, or traffic acquisition costs, was $50.95 billion.



Apple’s profit and revenue for the April-June period exceeded analyst estimates. The California company earned $21.7 billion, or $1.30 per share, nearly doubling profits earned during the same period last year. Revenue surged 36% to $81.4 billion.

“Our record June quarter operating performance included new revenue records in each of our geographic segments, double-digit growth in each of our product categories, and a new all-time high for our installed base of active devices,” said Luca Maestri, Apple’s CFO. “We generated $21 billion of operating cash flow, returned nearly $29 billion to our shareholders during the quarter, and continued to make significant investments across our business to support our long-term growth plans.”

Upcoming challenges that Apple may face include shortages of computer chips and whether it will force the company to delay its next iPhone this year, as it did last year. While Apple expects revenue to rise 10% in the current quarter, it said it may have more trouble getting parts for iPhones and iPad during the upcoming months.




Microsoft reported quarterly profits of $16.5 billion, up 47% from the same period last year. The net income of $2.17 per share beat Wall Street expectations. 

The software maker also topped forecasts by posting revenue of $46.2 billion in the quarter that ended on June 30, a 21% increase over the same time last year.

Microsoft profits have soared throughout the pandemic due to ongoing demand for its software and cloud computing services for remote work and study. Growth in sales of Microsoft's cloud services, which compete with Amazon and other companies, and its Office productivity tools for handling work documents and email both outpaced overall revenue growth. The company's historical pillar, personal computing, grew just 9% in the quarter.
