Understanding Data Center Power Technologies

by 42U

Interruptions to critical business processes, whether due to hardware faults, production breakdowns, communications failures or insufficient - or even non-existent - protection against voltage fluctuations, can have far reaching consequences. After all, system availability and the reliability of IT infrastructure platforms are decisive factors for the efficiency and productivity of company processes - and thus equally for business success.

Miniaturization and the ever greater performance of the hardware components place new demands on modern power management concepts. The answer to this dilemma: Power management with RimatriX5. The demands with regard to redundancy, scalability and maximum availability are bundled into a single system. Together, the solutions help to reduce operating costs and boost the availability of the overall system. It is even possible to retrofit new modules without interrupting operation.

Particularly effective: The "n+1" technology, which ensures optimum redundancy and enhances availability. Indeed, the Power Modular Concept (PMC), with its innovative distributed parallel architecture (DPA), stands for ultimate system availability.

The power management product range for power distribution in the data centre is based on the consistent implementation of plug-&-play expansion - with no need to interrupt current operations. Downtimes are avoided and future operating costs are lowered.

Power System Module (PSM)
Busbar

• Fully wired with shock hazard protection
• Two supply circuits for redundant configuration
• Loads up to 48 A or 96 A
• Active power system module
• Remote power supply administration via SNMP and HTTP
• Current measurement and display
• Slot switching and user administration

Power System Module (PSM)

Optimum cable management:  Space-saving integration into the rack also serves to cut installation costs

• Power Distribution Rack:
  Local distribution up to 250 A permits connection of eight PDM systems
• Expandability:
  Expandable without interrupting operation
  VDE-tested shock hazard protection
  Direct supply-side connection to the PSM busbar
• Flexibility:
  Cable-based connection to the PSM busbar for maximum planning flexibility
• Power Distribution Module:
  Local power distribution up to 40 kW in server and network enclosures
  4 fused three-phase outputs, 3 x 400/230 V, 16 A each
• Redundancy:
  Redundant infeed with option of mechanical locking

Thanks to the modular DPA system architecture, it is possible to expand capacities and stored energy times without interrupting operation.

Single-phase UPS, power range 1 - 6 kVA

• High-quality double-conversion technology with optimum sine-wave output voltage
• Battery expansion for extended stored energy time
  Intelligent battery management monitors battery readiness and guarantees system availability; furthermore protection against overcharging and exhaustive discharge.
• Scope of delivery offers software compatibility for all standard operating systems
• System load reduced by preventing continuous server polling after shutdown

• Performance/modularity/redundancy
  PMC is a new three-phase UPS concept offering modular "n+1" redundancy on the basis of double-conversion technology. The modular configuration permits capacity expansion through the integration of additional hot-swappable UPS modules.
• PMC modules
  PMC modules for the power classes 10, 20, 30 and 40 kVA are prepared for 482.6 mm (19˝) installation in TS 8 server racks.

• Maximum availability
  The "n+1" system architecture means that there are always at least two modules able to share the critical load. If any module should fail, the other modules automatically take over the whole connected load without interruption.

"n+1" System Architecture

DPA
The distributed parallel architecture comprises integrated control electronics for rectifier, booster, inverter and static bypass. The CPU, furthermore, possesses parallel intelligence for enhanced reliability.
