- 1. Buildings & General Specification by Charis Charalambous / Ucy Noc Team Data Centers
- 2. Data Center is the facility that was designed to host equipment that refers to telecommunication systems, computational systems and storage systems. All the active equipment installed in a data center is usually equipped with dual power supplies and Ethernet connections. Also dual internet service provider connections and dual power feeds, UPS and Generators apply to data centers to ensure redundancy and business continuity. Data Center Definition
- 3. • Data Center Design philosophy • Rack and Computational equipment loading • Numerous environmental sensors and monitoring services • Data Center Design Criteria • Architectural Design -> (space planning , floor, light, security etc),Redundant access to ,No exterior windows ( increase heat and security risk),Delivery of Large equipment,Provide authorized access & monitored • Structure Wiring-> Fiber / Copper/ twinxial Cables • Electrical-> UPS /Generator / Dual feeds on the Grid/ • Cooling / Mechanical-> HVAC systems / dual connections • DCIM System-> environmental Sensors , smart PDU’s , fire suppression Contents

- 6. Electrical Wiring Multiple Power Grid Connects ELECTRICAL Dual and redundant power feeds on the SPDU Generator capacity to include cooling UPS capacity to include cooling and lights Color coded PDU - identification on the PDU/ panel id/ breaker
- 7. Cooling / Mechanical Managing the airflow around the server cabinets is critical to prevent hardware from overheating - solutions to manage this is by using blanking panels foam tape, sealing grommets and high-flow air tiles. Sealing the openings in the raised floor and the bottom and top cover of racks with sealing grommets prevents cool supply air from escaping where is not needed. Determine cooling delivery methodology Room , rack , row Blank panels , sealing grommets Cold air containment Dual power and cooling paths Avoid blocking cooling ducts and return air paths Determine the CFM requirements per RLU / Rack Proper internal configuration of racks (airflow) Determine critical heat load
- 8. Fire Detection and Suppression Detection -> both heat and smoke detection Airflow patterns determines location of detection units Suppression ->Folllow NFPA 75 standard Use of chemical systems or clean agent (FM200, inergen etc) Install springer systems and connect with DCIM to interfere with the crack units in case of fire.
