August 03, 2010, 11:30 AM — Sure, consumer gadgets are getting most of the attention these days, but data centers are getting some love too. These new products and technologies promise to solve real data center problems or are already working to make enterprise operations run more smoothly. How many are on your wish list?
1. Fiber optics with a twist
The success of the HDMI cable in consumer electronics has proved that having a common cable that works with Blu-ray players, HDTV sets and just about any set-top box helps remove clutter and confusion. Intel has developed Light Peak following this same approach. It's fiber-optic cable that will first be used with laptop and desktop computers to reduce clutter and to speed transmission, but it could also make its way to the data center as a way to connect servers and switches.
The 3.2mm cable, which is about as thin as a USB cable, can be up to 100 feet long. Intel has designed a controller that will sit inside a computer, and cables are currently in production. Third parties, including Hewlett-Packard and Dell, will start making computers with Light Peak fiber-optic cables in them by 2011, according to Intel.
For data centers, Light Peak presents a few interesting possibilities. Fiber optics have been in the data center since the early 1990s, when IBM introduced its Escon (Enterprise Systems Connection) product line; it connects mainframes at 200Mbit/sec. Light Peak differs in that it runs at 10GB/sec., and Intel claims that the components will be less expensive and lighter-weight than existing fiber-optic products.
"Intel claims Light Peak will be less complex and easier to manage by eliminating unnecessary ports, and deliver the higher throughput required by high performance e-SATA and DisplayPort systems," says Charles King, an analyst at Pund-IT in Concord, Mass. "If the company delivers on these promises, Light Peak could simplify life for data center managers plagued by installing, managing and troubleshooting miles of unruly optical cables."
Success here will depend on "how willingly developers and vendors" embrace Light Peak and build products around it, King explains.
2. Submerged liquid cooling and horizontal racks
Liquid cooling for data centers is not a new concept, of course, but Green Revolution Cooling has added a new twist. For starters, the rack is turned on its side, which helps with cable management and makes it easier for administrators to access equipment, and the horizontal rack is surrounded by liquid. A new coolant, called GreenDEF, is made from mineral oil that is nontoxic, costs less than other liquid-cooling methods and is not electrically conductive like water, according to a GR Cooling spokesman.
"The liquid actually moves through the floor and circulates up through all of the computing nodes," says Tommy Minyard, director of advanced computing systems at the Texas Advanced Computing Center, part of the University of Texas at Austin. This means more-effective cooling because heat is moved away from the processors via cables on the sides and under the rack, he explains. Minyard is installing GR Cooling systems in his data center and expects a 30% to 40% savings compared to traditional air-cooled systems.

Green Revolution uses horizontal devices for racks, along with a new type of coolant, to reduce energy costs in a data center.
Minyard says liquid cooling has made a rebound lately, recalling the days when Cray offered submerged cooling systems, and he notes that even IBM is moving back into chilled-liquid-cooling some compute nodes.
Pund-IT's King says a major issue is that enterprises have fought the return of liquid cooling in the data center because of the high costs of implementing the technology and because it is unproven as a widespread option.
