Application hosting - SAP

IBM Applications on Demand for SAP solutions are hosted at our hardened, fault-tolerant data centers, which have been designed to accommodate a very wide variety of application platforms and networking equipment. Our current North American Applications on Demand data centers are located in Sterling, VA and Mesa, AZ.

These centers are built to universal business code standards and offer security-rich facilities from both a physical and logical standpoint. The Applications on Demand hosting facilities offer an environmentally controlled application hosting environment that is connected directly to Tier-1, Internet Service Provider (ISP) networks.

• Two diversely routed public utility circuits provide electrical power to the Applications on Demand facility.  Each circuit has its own dedicated switchgear and transformers located on the property.  The main switchboards within the facility control both of these circuit sets via a tie main, which allows switching from one circuit to the other.  The main switchboard provides continuous power throughout the facility by feeding redundant uninterruptible power supply (UPS) systems and other distribution panels.
  
  
• The UPS systems consist of redundant racks of batteries, redundant UPS cabinets, a UPS control cabinet, and a maintenance bypass cabinet.  The batteries provide continuous operation of the critical systems in case of a commercial power failure.  Parallel configuration allows maintenance without impairing the systems’ ability to sustain power should an outage occur.
  
  
• After 1.5 seconds without commercial power, automatic switches activate the diesel engines and generator sets.  Within 30 to 45 seconds, the generators can supply the necessary power to maintain the facility.  The diesel engines, generator sets, and fuel supply are situated to eliminate vibration and noise in the building.  These generators can run indefinitely and the facility has enough fuel stored for up to three weeks at all times.
  
  
• The Applications on Demand data center’s structural design provides environmental independence between the general office area and the specialized computer operations areas.
  
  
• Electrical power, telecommunications, and environmental conditioning are fully redundant.  Heat, smoke, and fire detection and suppression systems are located throughout the building.
  
  
• An advanced system monitors temperature, humidity, and other environmental conditions.  The system’s video monitors display all alarm conditions.
