Space-saving server cluster cabinets go on show

Knurr will be a conference sponsor and seminar presenter at the forthcoming Data Centre Dynamics Conference and Expo in London, UK, on 27th and 28th October 2005.

See the very latest space-saving server cluster cabinet solutions, (up to 22kW) from Knurr, a conference sponsor and seminar presenter at the forthcoming Data Centre Dynamics Conference and Expo in London, UK, on 27th and 28th October 2005.

Knurr is a multi-national manufacturer of enclosure cabinets and associated technologies.

Having introduced its CoolTherm, air-to-water cooled server cabinets in 2003, the company helped create the world's first, commercially operating, totally water-cooled PC cluster, as part of the massive grid computing (LCG) project - the world's largest international scientific grid.

Knurr's continued development and refinement of its air-to-water server cabinet cooling systems, has culminated in a series of scalable thermal management solutions.

At present, up to 22kW of heat can be managed in a single, self-contained 19in CoolTherm cabinet.

The 22kW CoolTherm is believed to have the highest performance on the market, particularly as it requires no additional addon enclosure space.

The closed-loop, self-contained design, eliminates the need to evacuate hot air into the computer room ambient air, which dramatically reduces the load on computer room air conditioning (CRAC) systems, or may remove the need for CRAC operation, with attendant cost savings.

Dr Peter Koch of Knurr is giving a seminar presentation and will talk about the significant total cost of ownership) cost-saving benefits of Knurr technology, at the Data Centre Dynamics event, on day 1, 27th October, Hall 1, 1425 GMT.

A new and innovative Knurr solution to upgrading existing, 19in standard air-cooled cabinets is the CoolAdd system, claimed to be a major breakthrough in 19in cabinet thermal management.

Based on the proven technology of CoolTherm cabinets, CoolAdd provides "retro-universal" 8kW cooling capacity for any 19in IEC standard cabinet, simply by replacing a cabinets existing rear door and connecting a chilled water supply.

Available as standard for cabinets from 45U high upwards, with widths from 600mm wide or higher, CoolAdd, readily achieves a highly cost-effective, entry-level 'closed-loop' controlled cooling solution, ideally suited to modern 'server cluster' cooling requirements.

The 8kW cooling capacity of CoolAdd, effectively doubles the typical, nominal 4kW cooling capacity of CRAC reliant conventional high-density cabinet layouts, enabling the doubling of servers per cabinet and the potential to halve floor space for the same total server capacity.

CoolTrans is another Knurr development which will be shown at the London event.

It is an optional, PLC-based unit, specifically designed to operate with Knurr CoolTherm and CoolAdd, water-cooled cabinets, to control, manage and monitor the water supply and maintain cabinet thermal control.

Housed in a low-height, stand-alone 19in style cabinet, it removes the responsibility from end-users to provide control of a cabinet's required water inlet conditions and simultaneously will manage a group of CoolTherm, or CoolAdd, cabinets individual thermal requirements.

Monitor and control of data between CoolTrans and each CoolTherm cabinet can be fed into a Knurr rack management system via a LAN for complete monitoring of the system and its security.

This also includes the use of remote interface via FTP.
