Hiross XDFN Closed Loop Cooling for High Density …

1 Precision Cooling forBusiness-Critical ContinuityHiross xdfn Closed Loop Cooling for high Density RacksWhether you have to manage a 10 sqm ServerRoom or 1000 sqm Datacentre, we have thesolution for your needs, from Closed Loop RackCooling to Integrated continuity ExpertX-treme Solutions Adaptive Cooling and Power ArchitectureHiross xdfn Closed Loop Cooling for high Density RacksIt was 24 kW per is 24 kW per Heat Removal to the X-tremeWithout Water Inside the Datacentre! Hiross xdfn : Air Flow DistributionCool the Server not the spot due to insufficient can restore the correct TemperatureHot Spot ManagementNew Technology Servers increase dramatically increase computingcapacity which also means an increase of heat dissipation needs.

2 A rack equipped with Blade Servers can easily exceed 20 kW thuscreating hot spots not manageable with standard air conditioningsolutions (refer to picture A where red hot spots are shown).Thanks to our expertise in Precision Cooling and AC Power Systems,we have designed an indoor enclosure system for high Density ser-vers with built in power back up (refer to picture B where the hotspots have been treated and cooled).Up to 24 kW/rackIdeal for high Heat and integrated cost of xdfn cools the Servers not the room and guarantees a safe protection for customers servers offering a completesolution for redundancy, power protection, fire extinguishing,back-up ventilation and SNMP Loop rack Cooling .

3 AdaptiveX-treme Solutions are the answer to this xdfn is part of the Liebert AdaptiveCooling Architecture which can provide a roadmap to deal with increasing heat Density , and with maximum flexibility and scalability and the lowest cost of Alone Singular unit reliable & simpleModular Standard units withfixed sizes that worktogether Cost savings by retai-ning initial investment Added redundancyN+1 Redundancy & ModularityThe modular design allows redundancy, rapidreplacement of faulty units and +1 Redundancy each block of xdfn units (coolingmodule+racks) there will be one redundantcooling module connected in LANwiththe other Cooling modules, ready to be acti-vated in case of failure or maintenance ofone of the running Cooling and Power Architecture Back up VentilationHiross xdfn is also equipped with a back- upventilation system which ensures the circula-tion, inside the rack , of the air coming fromthe data centre room in case of coolingmodule or mains power failure.

4 Cost savingThe UPS will be required to give poweronly to the small back-up fans, and not to the rest of the air-conditioner system. SafetyBack up ventilation protects your businessfor enough time to allow the generator to start and restore the power supply, or for other causes of failure to be corrected. When power is restored, the back-up ventila-tion will be automatically switched off andthe Cooling module will run as in Flexibility with internal modularity A unit with single direction for growth Monitoring and ControlHiross xdfn features an innovative 32 bitMicroprocessor controloffering the capabili-ty of integration in an SNMP monitoringsystem, or simple browsing of the unitthrough the web.

5 Fire ExtinguishingTaking care of your business means provi-ding protection for all possible Hiross xdfn features a FireExtinguishing System based on Vesda laserfocus sensors continuously monitor the airinside both the rack and inside the CoolingModule. If smoke is detected an inert gas willbe introduced to mix with the air inside theModule to reduce the Oxygen xdfn is an integrated equipmentcabinet with built in Cooling , power distri-bution, rack for server location, monitoringand fire extinguishing system offering fullredundancy and back-up ventilation. Optimal building blocks that work together Ultimate reliability, flexibility and lowest Total Cost of Ownership Fewest points of failure Reconfigurable to adapt to new technologieswith the Capability to move to higher TiersElectrostatic discharge preventionHumidity is a key issue for Servers becauseboth high and low humidity may damagethe electronics.

6 The Cooling module isequipped with Humidity control in order toalways keep the adeguate humidity levelwithin the rack . ControlThe control contributes to efficiency improvements by enablingmore precise control of temperature and humidity and by allo-wing multiple xdfn units to communicate and work together as monitors all functions and generates reports or alarms as allows a service engineer, from a centralized location, to overseethe operation of Hiross Hiross unit has a Unit Diary that shares unit maintenancehistory with any authorized user or logged-in service contact,including records of what others have Web CardThe control through the OpenComms Web Card provides theHiross xdfn system with SNMP and web-based control can be set to be monitored and controllednot only from aNetwork Management Station, but also from any PC runningMicrosoft Internet Explorer.

7 The animated Power Flow allows the condition of the systemto quickly be Power Monitoring and ManagementPower distribution inside the rack is provide the capability to monitor and control each socket offering control of the total RMS Amp, RMS Volt and kW/hthrough SNMP, Telnet and WEB & ControlHiross xdfn with digital scrollThe Cooling module, self-contained in the xdfn product, is a modular direct expansion unit with remote air cooled condenser. The Cooling capacity is modulating thanks to the use of digital scrolltechnology. The refrigerant used is R407C. The Cooling module is availablein different configurations, including chilled water on modular design of Hiross xdfn Closed Loop rack Coolingallows for the racks and Cooling modules to be combined, in orderto provide Cooling to multiple 42U Racks and AccessoriesHiross xdfn features a 42U rack that can be configured accordingto users needs with the following accessories.
