With the trend to computers of higher and higher performance and at the same time an ever-tighter package density in server racks, demand is increasing for intelligent systems for the optimization of energy and space efficiency. High density solutions are what IT decision-makers are looking for. Faster and more powerful server systems are being housed in smaller and smaller spaces. Heatload spots of up to 21 kW have to handled, whatever the temperature of the ambient air. The market demands complete, space-saving solutions for reducing the heat level of server cabinets.

Demands relating to safety, the autarky of the entire system and power management are also rising steadily. The remote maintenance of a computer center or of individual server locations is the current requirement of the industry. Practically all the cabinet parameters from temperature, moisture, smoke and vibration to door contacts and access check and mains-phase monitoring should be recorded and documented in a single unit.

Side-by-Side Installation and Mounting:

There is consequently a strict climatic separation between rack and computer center. Through the additional separation of the cooling unit in its own integrated and enclosed unit, the rack climate is not affected when the cooling unit is opened while in operation. An optimal climate is continuously maintained for the servers. For protection from environmental influences, the SP54_Q Rack comes with the IP54 protective system as standard.

Protection from Environmental Influences:
Through the separation of server cabinet and cooling unit, two autarkic areas are established which can be managed in safety and service respects as desired by the customer without affecting the system in operation. Four-point interlocking is a standard feature of air-conditioned cabinets to assure the perfect sealing of the rack.

Closure Safety and Accessibility:
With UNIQLE, TechXact is systematically implementing the principle of a cooling system integrated in the server rack. The decision for integration is a logical step. Server space is not unlimited! And through the trend to higher and higher computer performance accompanied by a greater packaging density, server racks must assure a maximum of space efficiency. This enables a maximum computer density per m2 floor space to be achieved.

Element 2 - Up to 21 kW Useful Cooling Capacity on a Floor Space of 0.96 m2:

Redundancy / high fail-safe reserves through two fans In the event of sensor fracture or fan failure: automatic system adjustment to 100 % fan output and 100 % valve opening Integrated function control and monitoring self-contained and enclosed housing design Independent unit, separate from cabinet parts carrying water only in the floor area and in a separate housing 100 % circulating air– thermal independence in relation to ambient air access to all active components from the front, fans on the suction side, replacement through the front door Maintenance / replacement of heat-exchanger without dismantling other components Fan-performance adjustment by speed regulation and 3-way valve in water circuit Regulation of incoming-air temperature Energy requirement matched to performance Optimal air distribution commercially available connections at cooling unit counseling by specialist partners for planning and installation of cooling equipment.

Equipment Components:
High-performance heat-exchanger, featuring aluminum fins and copper piping, hydrophilic coating EC radial fans with integrated electronics 3-way valve with electronic actuator. Generously dimensioned condensate tray panel with insulation – appearance of condensation water at the housing excluded.

Element 3 - Power Management: Highly Available and Reliable:

The UNIQLE Power Management System is designed for 32 amps and distributes this safely and reliably over the corresponding cutout components to the individual consumers. The system can be extended by remote control network switches with Ethernet connections for IP networks. In this way, all components can be switched on or off individually or jointly via the network.

Redundant power supply for several servers possible with one unit only 1.5 U space requirement through compact design simple feed via cable of up to 5 x 4 mm2, max. 3 x 25 A Simple connection of servers via blocked low-power IEC connectors, earthed plug sockets or other international variants safeguarding of outputs with one B10A automatic cutout in each case.

	Power Connectivity
	Consumers switched on and off by remote Triggering via network
	Complete integration in network environment via web browser
	Switched individual low-power connector outlets: switch state is maintained during power failure
	LED status display
	LED link and traffic display freely configurable password protection

The Rack Management System as an intelligent network agent monitors all the environmental influences on server racks. All the environmental parameters recorded are logically linked in a freely programmable filter system. As a reaction to certain environmental states, alarm messages are automatically generated and/or switch operations triggered. The Rack Management System offers all sensors for the most diverse environmental influences and at the same time controls their internal power supply.

In conjunction with the cooling system, the Rack Management System automatically and continuously determines and regulates the cooling requirement for the defined spatial state. All temperatures and fault messages can be read off from a display integrated in the Rack Management System.

Element 5 Partnership Management:

UNIQLE makes expert knowledge available. TechXact analyzes designs and supplies the right demand-specific server rack configuration for the individual customer. TechXact brings highly specialized and qualified partners together to ensure that the rack designed meets the defined requirements of the customer to 100 %. The customer gets this highly qualified service from a single source. In the service and maintenance area, professionals are always available worldwide with their own service concept.

Through the bundling of expert knowledge in the fields of rack design and air-conditioning, TechXact creates a new and innovative dimension for the IT-infrastructure in your company. Not individual solutions from different suppliers, not a design that only probably works.
