How he’d describe his work to a 10-year-old: “I make it so you can save endless selfies.”
Flash to the future: While your smartphone and laptop have gotten substantially sleeker and slimmer with more compact electronics inside, data centre equipment evolves more slowly. Occasionally, however, big jumps happen. One began a couple years ago when Wayne and his team — which he says “dreams up what’s needed in the data centre of the future” — set out to “go figure out the best way to deploy flash in a server.” Flash is a kind of chip that stores data, replacing the last-century spinning hard disk drive. Flash is both faster and more reliable, and most important, it’s smaller. But the size and shape of most drives are based on those old spinning disks, which have been “around for 30 years,” Wayne says.
Hello, ruler! Er, EDSFF: The team aimed to create something more compact, more efficient and easier to service and replace. They narrowed dozens of ideas down to three and showed them to select customers for a vote. The winner? The aptly nicknamed “ruler.” The long version (now an industry specification called EDSFF, which includes two other form factors) is about 12 inches long, 1½ inches wide, and a measly one-third of an inch thick.
A seriously cool design: While it wasn’t easy, simply changing the size and shape of the drive had a surprising set of positive side effects. “We didn’t just improve density — we improved thermals,” Wayne notes. Thermals are a major factor in the operations and expense of a data centre (cooling alone can be the biggest cost). And though these drives will spend their lives hidden from view, the design has earned awards from the Industrial Designers Society of America and the Core77 Design Awards.
Reshaping the drive, and the data centre: Rule-based servers can be designed to let fresh air pass directly to the processors in the back of the machine, improving the cooling efficiency and opening the door to even higher-performing processors. “A new form factor itself isn’t all that exciting, typically,” Wayne says. “But because [the ruler] impacts everything about server design and helps increase performance and reach new levels of density, it’s a big deal. We’re redesigning the data centre with this — that’s the most fun part of it for me.”
Huge storage, tiny slot: The team wanted to achieve a petabyte of storage space — that’d be 4,000 256 GB smartphones — in a “1U” server slot that’s 1.75-inches high and 19-inches wide. Thanks to the ruler and new 3D NAND technology, 32 of Intel’s forthcoming 32-terabyte rulers will fit in that 1U space, and there’s your very slim, extremely efficient petabyte. Compared to a petabyte of hard drives, Wayne says, “we’ve delivered a 10x power reduction and a 20x space improvement. It’s pretty remarkable.”
