How open compute cuts server costs in the enterprise

Even if your organization’s not big enough to build your own servers and switches, you can still reap the benefits of OCP designs, including reduced costs.

The open compute project (OCP) means you can get the designs that Microsoft, Facebook and (to a lesser extent) Google use for their data centers.  The goal is to get original design manufacturers (ODMs) to build them for you rather than buying standard servers and switches from original equipment manufacturers (OEMs).

Six years on, it’s still mainly the largest of companies with the largest of data centers that are buying OCP designs, Forrester principal analyst Richard Fichera tells “Some of the larger financial services and large manufacturers are actively implementing OCP designs or OCP-like designs.”

Even so, he says, the project has had a big impact on the hardware that enterprises and mid-size companies buy. “Buying OCP-compliant systems is really still a high-end phenomenon but there’s been a more subtle ripple effect over the last few years that’s reached a long way.”

“When OCP started, almost all the major server vendors had what they called value product lines; systems that were stripped down and a little less expensive, with specs that were a little lighter all the way round, from connectors to power supply efficiency,” Fichera says.” OCP really highlighted a lot of the ways they could take further cost out of their servers and, by this point, all the major vendors have servers that have been influenced by the OCP designs. You can see that by the way they design systems and the resulting pricing of the entry level of value systems.”

But you won’t see those cost-cutting measures reflected in the list prices, Fichera says. “They don’t necessarily advertise as ‘this is a dirt cheap alternative to run your software’ but it gives them a tremendous amount of wiggle room when it comes to discounting.”

Bringing prices down was always part of the OCP plan, says Open Compute Foundation CEO Corey Bell. “We believe that everything should be more open because it allows for greater collaboration and communications; it drives down costs and it drives up effectiveness and efficiency. Where we used to be in the industry, vendors got input from customers but customers didn’t have a seat at the table to design products. Collaborating and designing openly is better for everyone, and it drives down costs.”

Enterprise scale, enterprise support

“A lot of the OCP designs were too wild and crazy for enterprise data centers, but they have some very mainstream 2U two socket designs with very standard server specs now and that’s trickled out into the industry,” says Fichera.

That’s exactly what Bell wanted to see happen. “We’re trying to make it easy for everyone to consume OCP and we’re pushing to overcome more of the hurdles. As we’ve brought on more component suppliers and more service providers as well as full products, we’re getting closer. When a product is submitted to OCP, we think about who would this work for and how would they get it.”

What OCP has already done is make cheaper systems available to everyone, albeit indirectly. “The difference between enterprise-class servers and a high-volume cloud server could be as much as 20 percent,” Fichera says, but he adds that “there’s now little difference in price between a ‘value’ server from the traditional server suppliers and an OCP design.”

What keeps many enterprises buying those value servers rather than OCP designs often has nothing to do with the hardware design, Fichera says. “Medium-size companies are still very sensitive to service arrangements,” he says, giving the example of companies buying several hundred servers who had been approached by server ODM Quanta with a slightly lower price than the traditional vendors, and turned down the deal.

“The rationale behind the decision is that they weren’t ready, for that price difference, to take the risk of what it means to be supported by a company like Quanta,” Fichera says. They fully understood that with a couple of hundred servers that they wouldn’t be getting the focused attention of Dell or HP [that a larger customer would get], but they were nervous about relying on a company with no visible presence in end user support.”

That’s an area OCP is working on, Bell tells “At the end of the day, it’s not just about deployment; for mid-range and smaller businesses, distribution and support is key. That’s where some of the major vendors have done a great job.” He notes that Dell and HP are already part of the OCP ecosystem, and Lenovo joined in early 2016. “We’re increasing and managing the ecosystem to provide that. There are going to be multiple players that enterprise will be able to go to,” he promises.

Cloud power

Even larger-scale systems like HPE’s Cloudline — which uses an OCP design rather than the proprietary technology used in ProLiant servers, and is manufactured in partnership with Foxconn rather than by HPE — are coming down market, says Fichera. “Initially they were very cagey about selling only to really big users but I get the impression they’re coming down now. If you want a couple of thousand units instead of ten thousand, I think they'll talk to you now — and they have a lot of competition.”

While making data center power usage more efficient has been a big focus in OCP designs, that’s one area that isn’t directly relevant to enterprises (even though they typically pay more for power than cloud providers do). The biggest improvements require esoteric infrastructure like high-voltage DC power distribution that hyperscale cloud providers have adopted but few enterprises have in their data centers.

The good news is that both general customer demand and the lessons learned from OCP systems mean that server makers — and the power supply vendors they all use — have made their systems more energy efficient anyway. “Systems continue to exhibit big jumps in capacity in terms of performance per server; every generation of the base semiconductors has become more power efficient and both system vendors and CPU vendors have become more focused on power efficiency,” says Fichera.

In addition, many enterprises indirectly benefit from power efficiency improvements through cloud usage, Fichera points out. “Widely available cloud substitutes for a lot of workloads have reduced the number of people who wake up and have that ‘I have to build a new data center just to add more servers’ moment.”

Scaling up for private cloud

Even before OCP, the idea of buying barebones servers at scale appealed to some large businesses. Fichera knows of one large financial services company (he identified it only as one of the top 10 financial services organizations in the world) who approached an ODM in Taiwan. “They tucked one of their servers under their arm and said ‘Build me this but without this component, without that component, without this management agent; basically, build me a lower-cost version of this server.’ They bought probably 20,000 of them.”

Bell wants OCP to make that kind of custom manufacturing accessible to businesses of all sizes. “We want to make it easier to buy and use OCP, and to control your own destiny. With open collaboration, you can get exactly what you want, as opposed to being sold things you don’t need.”
