25 Critical Distribution System: TECHNICAL MEP BASIS PROGRAM-ELCTRICAL OF DESIGN PROGRAM-ELECTRICAL Electrical Mechanical Distribution system : Catcher System : The critical distribution system is divided into pods. Each pod has a dedicated primary system with a shared catcher redundant system. This redundant system provides concurrent maintainability, as well as an additional layer of redundancy for the data suites. The basis of design is based on a COLO type tenant. This design allows for a higher critical load with a small sacrifice to system redundancy. The critical load for each pod is 1.8MW. This includes a N setup for the UPS system. A 2N system can be achieved in the same floorplan with 0.9MW of critical load. Electrical distribution design can be altered based on tenant requirements, however the basis of design is to show the maximum power density with acceptable levels of redundancy. Power to each pod is provided by a dedicated 2500kVA transformer. Backup emergency power is provided by a dedicated 2500kW/3125kVA standby diesel generator. Both power feeds into the Main Switchboard (MSB). Transfer between utility to standby power is controlled via an automatic transfer operator. The MSB supplies power to (2) 900kW/1000kVA UPS s (each with 10 minutes of battery backup at full load), UPS bypass, mechanical equipment, and general power. Each UPS feeds a Maintenance Bypass Switchboard (UHD). 300kVA PDU s serving the data suite are then served from this switchboard. Each PDU is served by a static transfer switch that will transfer the load to the catcher system in the event of a power failure. The system supports (12) total PDU s, with (6) PDU s per UPS. Mechanical Chiller Plant is located at this roof level of the building. The chiller plant is a modular design, so that an additional chiller is added as each new pod is provided. This saves upfront capital associated with a large chiller plan system. Each pod feeds its own dedicated chiller. The chillers and associated mechanical support equipment are fed from the MSB board, providing automatic transfer between utility and generator in the event of a power failure. The chiller plant is designed as an N+2 System. The (2) redundant chillers will be fed from the catcher systems. The fire and jockey pumps are located in the basement. Separate dedicated 480V normal and emergency services via dedicated automatic transfer will be provided to fire pump. Each set of (4) pods is supported by a single catcher system. This is a 1-to-catch-4 design where the catcher system can take over the entire critical load for a data suite. The catcher system is designed to mimic the pod system. Each catcher system has it s own electrical distribution consisting of generator, utility, MSB, UPS, and UHD boards. The catcher system is designed for a first-come-first-serve basis with no established priorities. The catcher electrical distribution is located on the generator floor. Miscellaneous Power: UPS power will be provided to the main NetPOP rooms on the basement level. Emergency power will be provided to both Fire and Jockey pumps. New life safety emergency generator will support both fire and jockey pumps. UPS power will be provided to main control panel for security system equipment. Normal power will be provided to loading docks equipment on the first floor of the central utility plant. 25

26 TECHNICAL MEP BASIS PROGRAM-FIBER OF DESIGN PROGRAM-FIBER Fiber Program General: The building will outfitted with spaces and infrastructure to accommodate multiple service providers. Spaces for service providers, cabling and internal wiring closets will be in separately secured areas, allowing access to parties only as needed. All of the communications infrastructure will be redundant, consisting of two sets of conduits, NetPOP rooms, risers and IDF rooms. Redundant systems will have physical separation from each other as much as possible. This is in keeping with data center best practices and tenant expectations. Incoming services: A number of communications service providers have existing infrastructure within a short distance of the building, many on congress. The closer they are, the easier it is to attract them to the site so they can establish a presence in the building for tenants use. Service providers will be invited to establish competitive service on site. Two underground vaults with manholes in the street will be located outside the building, one on congress, and one on clark st. Each will intercept service providers conduits and cabling. From each vault, a bank of at least twelve 4 conduits will route into the Central Utility Plant (CUP) building. There will be two NetPOP rooms in the CUP building to receive the conduit banks from the underground vaults. Service providers will be provisioned conduit space as needed. They will also be assigned space in the NetPOPs to terminate their cables and locate rack-based equipment. Most if not all of the incoming cable will be fiber optic. Service providers use their on-site equipment to convert the fiber circuits into all manner of circuits and cables for use by tenants, including voice, data, TV, and specialty circuits. Internal Communications Infrastructure: From each NetPOP, an internal bank of conduits will route across the bridge to the main building communications risers. Building owned and maintained communications cables will route from the NetPOPs through these conduits and via the risers to each IDF in the building. There will be two IDFs per floor of the data center. The IDFs are where riser cables will terminate and be crossconnected to tenants. Each tenant will get their services by installing cables to the IDFs as they lease space in the building. They will each have the opportunity to connect to multiple service providers via the two IDF closets on each floor. The cabling infrastructure will consist mainly of fiber optic cables, utilizing the parallel optics and low-loss splices and connectors. There will be an emphasis to create high density fiber system in as small a space as possible while keeping it organized and manageable. 26

27 Security Overview: TECHNICAL MEP BASIS PROGRAM-SECURITY OF DESIGN PROGRAM-SECURITY Security Program Data Center: Data Center (Continued): An integrated security system will be provided to provide protection within the building. The system will include card reader access control, biometric readers, visitor management control, video surveillance monitoring, duress alarm monitoring, and two-way intercoms. All security system monitoring and control will be managed from the security control room. Security will be implemented using multiple nested security zones to provide defense in depth. Security zones will be based on building access, data center access and individual data suite access as well as separate access controls for back-of-house and facility infrastructure spaces. Security: The site is in a city environment so there is no setback from public spaces. This means security measures will begin at the building perimeter with multiple layered zones of security measures. This layered approach is important in order to segregate access to specific areas based on operational need. All access to the data centers will be controlled by a mantrap which provides a high level of security and access control. The mantrap consists of a set of two interlocking doors which are controlled such that at no time will both doors be unlocked or open in order to prevent multiple people from entering without proper security validation. The mantraps will incorporate biometric readers, intercoms, alarms and surveillance cameras. Security at the individual data center floors will typically include access control and video surveillance cameras. This is anticipated to be managed separately by the individual tenant using their own dedicated access control system and video surveillance system, but they could be optionally managed as a service by the facility management and monitored at the facility security control room. There are multiple options for access control (such as card reader, biometric readers, and use of PIN) depending on the requirements of the individual tenant. Access to back-of house spaces will be controlled. These spaces include electrical rooms (UPS, battery, switchgear, etc.), mechanical rooms, fire systems rooms, utility entrances, and IT rooms. Camera coverage at the data center will be provided for all building perimeter doors, data center entry points, parking areas, lobbies, common corridors and back-ofhouse areas. Security measures will begin at the building perimeter with physical construction to prevent access, access control measures to prevent unauthorized access, alarmed emergency egress doors and cameras at all building perimeter entry points. Security operations will take place at the security control center located on 1 st floor. All security system alarm monitoring and control will be managed by security personnel staffing this space. Security personnel will be able to receive security alarms, assess the alarms, monitor security conditions, and initiate appropriate response. This center will also include access enrollment and badging capabilities in order to validate authorization and to issue access credentials. Access to the data center will be managed via the security control center. This will include mantrap monitoring and control as well as visitor management capabilities. All unbadged visitors will be processed at the security control center to validate their authorization, to issue visitor credentials, and to log visitor information. The loading dock will be secured with a card reader at the personnel entrance, and the open/close state of each of the vehicle doors will be monitored from the security control center. Cameras will be used throughout the space (both interior and exterior) to monitor security events. All elevators and stairwells will be monitored and controlled to prevent unauthorized access to back-of-house areas. These spaces include electrical rooms (switchgear, generator room, etc.), mechanical rooms, fire systems rooms, utility entrances, and IT rooms. Camera coverage will be provided for all building perimeter entry points, parking areas, loading dock areas, lobbies, elevators, stairs, common corridors and back-of-house areas. 27
