PRODUCT ANNOUNCEMENTS AND DEPLOYMENTS


Dell fi rst to validate higher IT hardware temperatures


Cooling products and their users get smarter


The past few months saw some quite major developments in the sphere of data center cooling. Game-changing technological developments and creative energy-efficiency designs have been announced.


Google publicly launched its huge seawater- cooled Finland data center, Dell became the first vendor to validate a line of IT gear to work within the newly expanded ASHRAE temperature and humidity envelopes, and Schneider Electric made a bold statement, saying it now has a cooling solution for every possible data center design out there.


A few more developments made a splash, but let’s start with Dell:


In reaction to the recent release by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) of its latest ambient temperature and humidity guidelines for data centers, Dell validated an entire line of IT equipment that can operate within the expanded temperature and humidity ranges.


ASHRAE updated the guidelines to enable data center operators to save energy and

expand the amount of geographical locations where air-side economizers can be used to supplement mechanical cooling.


Data centers that support this equipment will be able to turn up in-take air temperature and save energy previously used by air conditioning. In addition to reduction of energy consumption by the cooling plant, data centers that follow the new guidelines can, in some cases, run with chillers completely turned off. In some climates, facilities will be able to be designed without any chillers at all.


Dell’s Fresh Air cooling solutions portfolio includes servers, storage and network gear. These products fall under ASHRAE’s A3 and A4 equipment classes, which cover volume servers, storage, personal computers and workstations housed in a space with some control of environmental parameters.


Forrest Norrod, VP and general manager of server platforms at Dell, said Fresh Air prodcts will enable “aggressive” energy-consumption and operational-cost improvemnents even for data centers already using economization.


“The total Fresh Air solution,” he said, “with thermal, reliabilty and system engineering fully validated, is based on advanced


EMERSON’S CRAC CERTIFIED UNSHAKEABLE


Emerson got a seismic certification for the Liebert CW chilled-water-based CRAC. The solution now complies with the International


Building Code, California Building Code and California Office of Statewide Planning and Development standards (OSHPD), the company said. Fred Stack, VP of Liebert marketing at Emerson, said all configurations of the solution are covered by the certification.


This certification is especially targeted at the healthcare industry.


“This is especially good news for healthcare facilities in California, which are mandated to follow the seismic design requirements of the OSHPD,” Stack said.


Dell’s Poweredge R610, with Fresh Air validation engineering and design.”


The validation means Dell will guarantee these products will work normally if ambient temperatures go up to 113F on short- term excursions. The standard allowable temperature limit for most equipment now on the market is 95F.


The portfolio was designed for sustained operation at temperature ranges between -23F and 113F under allowable humidity between 5% and 90%, according to Dell. The servers, storage and network gear can run up to 900 hours a year at 104F and up to 90 hours at 113F. 
