66、N OF EPI.Page 14 of 43 9.General requirements This section describes the general requirements for Modular Data Center solutions(MDC).As per the definition in this standard,an MDC solution refers to a pre-manufactured solution based on indoor applications of hot-or cold-aisle containment structures.T

67、he system is designed to offer a single,universal air containment and structural support solution by configuring two cabinet rows to face each other,arranged in either a front-to-front or back-to-back orientation.An MDC can also be constructed as a single row of cabinets with a hot aisle or cold ais

68、le containment.The MDC is(often)placed within a computer room environment or any other building enclosure.This standard does not apply to containerized,prefab room-in-room or standalone(single cabinet)based Micro Data Center solutions.An MDC solution shall contain the following elements:Containment

69、structure with cabinets,ceiling and entry doors Cabinets to house ICT equipment Electrical sub system including,where required,UPS system Intelligent or standard rack PDUs Grounding system Electrical and telecommunication subsystem pathways Mechanical sub systems,where required,including cooling equ

70、ipment Interior lighting Fire detection and alarm system Monitoring system Optionally the MDC can contain the following:Flooring STS switches for single line corded equipment(optional)Access control system e.g.biometric access control VSS-Video Surveillance System Fire suppression system Pressure re

71、lief damper(optional;only required when internal fire suppression system is installed)Very Early Smoke Detection System(HSSD,VESDA etc.)The MDC shall meet all local code requirements related to construction,materials,fire safety,disability acts and other regulations.yu_ EPI-MDCS-MODULAR DATA CENTER

72、STANDARD:2023 COPYRIGHT EPI NO DUPLICATION IN PART OR WHOLE WITHOUT PERMISSION OF EPI.Page 15 of 43 10.MDC Ratings This Modular Data Center Standard aligns closely with industry benchmarks such as ANSI/TIA-942,EN 50600,and ISO 22237 in their classification framework for data centers.In defining this

73、 standard,the term Rated has been chosen as the classification indicator for various resilience planning levels which is equal to other classifications such as Availability Class.Due to the limited scope of an MDC,the rating system applies exclusively to the electrical and mechanical subsystems.It s

74、hould be understood that the MDCs rating will not result in the total data center environment to meet the rating requirements of other standards such as those mentioned earlier e.g.a Rated-4 MDC module connected to two electrical feeds originating from a single electrical distribution board inherent

75、ly faces risks due to the dependency on a singular supplying electrical distribution board being now a single point of failure.Consequently,it falls upon the end-user of the MDC system to ensure that all external elements of the MDC comply with the chosen standard.The following outlines the high-lev

76、el requirements for each rating level.Please note that apart from the electrical and mechanical requirements,all other elements such as security,fire safety etc.apply to all ratings.10.1 Rated-1:Basic A Rated-1 MDC is a basic MDC with no redundancy.A Rated-1 MDC is susceptible to disruptions from bo

77、th planned and unplanned activities.The MDC electrical and mechanical equipment meets the N-Capacity requirement with no equipment redundancy.There is no redundancy on the supply and return paths for both electrical and mechanical paths.10.2 Rated-2:Equipment Redundancy A Rated-2 MDC shall have redu

78、ndant electrical and mechanical equipment based on the N+1 capacity concept.A Rated-2 is less susceptible to disruptions from both planned and unplanned activities compared to a Rated-1 MDC.Although having redundant electrical and mechanical equipment,there is no redundancy requirement on the supply

79、 and return paths for both electrical and mechanical.Electrical and mechanical equipment maintenance will not compromise the MDC below N-Capacity.Maintenance on(critical)electrical and mechanical paths might require a shutdown of the MDC.yu_ EPI-MDCS-MODULAR DATA CENTER STANDARD:2023 COPYRIGHT EPI N

80、O DUPLICATION IN PART OR WHOLE WITHOUT PERMISSION OF EPI.Page 16 of 43 To comply with other standard rating requirements a Rated-2 MDC shall use a structured cabling system for telecommunication between the cabinet enclosures.Point-to-point cabling is only allowed between adjacent cabinets.10.3 Rate

81、d-3:Concurrent Maintainable(CM)A Rated-3 MDC is a concurrent maintainable MDC.Concurrent Maintainability means that planned maintenance on the electrical and mechanical subsystem of the MDC will not compromise the MDC below N-Capacity.However,resiliency is most likely reduced or no longer available

82、during the planned maintenance which is acceptable.The MDC shall have redundant electrical and mechanical equipment.A Rated-3 MDC has multiple supply and return paths for both electrical and mechanical of which,in principle,only one is active and the other path is on standby able to be activated whe

83、n maintenance is required on the active path.Preference is for both paths to be activated.Electrical and mechanical equipment maintenance or electrical and mechanical path maintenance will not compromise the MDC below N-Capacity.To comply with other standard rating requirements a Rated-3 MDC shall u

84、se a structured cabling system for telecommunication between the cabinet enclosures.Point-to-point cabling is only allowed between adjacent cabinets.Furthermore,the structured telecommunication cabling system should follow non-crossing routes,ensuring two distinct paths to each ICT cabinet.10.4 Rate

85、d-4:Fault Tolerant(FT)A Rated-4 MDC is a fault tolerant MDC.Fault tolerance means that the MDC can withstand a single fault at any given time on either electrical or mechanical equipment or a fault on either an electrical or mechanical path.Fault tolerance automatically means that the MDC is also co

86、ncurrent maintainable.Faults or planned maintenance on the electrical and mechanical subsystems of the MDC will not compromise the MDC below its N-Capacity.However,resiliency may be reduced or temporarily unavailable during such events.To comply with other standard rating requirements a Rated-4 MDC

87、shall use a structured cabling system for telecommunication between the cabinet enclosures.Point-to-point cabling is only allowed between adjacent cabinets.Furthermore,the structured telecommunication cabling system should follow non-crossing routes,ensuring two distinct paths to each ICT cabinet.yu

88、_ EPI-MDCS-MODULAR DATA CENTER STANDARD:2023 COPYRIGHT EPI NO DUPLICATION IN PART OR WHOLE WITHOUT PERMISSION OF EPI.Page 17 of 43 11.Structural Subsystem The cabinets are to be rear justified and aligned flush with the hot aisle when a Hot Aisle Containment systems(HAC)configuration is used.For Col

89、d Aisle Containment systems(CAC)the cabinets are to be front justified and aligned flush with the cold aisle.To achieve full containment and prevent bypass airflow,implementation of a roof/ceiling along with entry doors or an aisle end wall is required.The spacing in front of the cabinet within the

90、containment area shall be a minimum of 1.2 meter/3.9 feet to provide appropriate workspace.The MDC shall be prefabricated for rapid deployment.The system shall be designed to minimize space while shipping/transporting and should require minimum labor during the assembly and installation on site.The

91、systems shall come with clear,and up-to-date,assembly and installation instructions to include drawings and/or pictures where necessary.Where required,the MDC should have the capability to be fitted with anchoring points.11.1 Materials and finishing The construction materials utilized for the MDC mu

92、st consist of high-quality,non-corrosive material.The materials shall be painted,or powder coated.The MDC shall be constructed using materials and designs that mitigate unauthorized access to the greatest extent feasible,acknowledging the inherent limitations in preventing all physical intrusion att

93、empts,such as those involving forceful methods like prying with tools or impact from heavy objects.11.2 Structural Strength The vendor shall indicate the maximum permissible total static equipment load within each cabinet.Where required,the system shall meet the seismic ratings requirements of the e

94、nvironment in which it is placed.Where seismic mitigation measures are in place e.g.building and or containment system dampers,these should be taken into consideration to potentially lower the seismic rating of the MDC.yu_ EPI-MDCS-MODULAR DATA CENTER STANDARD:2023 COPYRIGHT EPI NO DUPLICATION IN PA

95、RT OR WHOLE WITHOUT PERMISSION OF EPI.Page 18 of 43 11.3 Cabinets Cabinets designated for ICT equipment shall have a minimum of 42U of usable space.However,when STS Static Transfer Switches,patch panels and/or network switches are utilized to accommodate single-corded ICT equipment,a reduced usable

96、space is deemed acceptable.The width shall be able to accommodate standard rack mountable equipment.The depth of the cabinet shall be compatible with the ICT equipment(to be)installed.All cabinets within the MDC,including both ICT and non-ICT cabinets,must have identical heights.While not preferred,

97、the width of the cabinets may vary if the lengths of both opposite rows are equal.The cabinets should offer the option to be ganged or bolted together both at the top and/or bottom.For CAC systems,cabinets should have back doors.Front doors are preferred but not mandatory unless dictated by security

98、 policies or cooling solutions requiring front doors.For HAC systems,cabinets should have front doors.Back doors are preferred but not mandatory unless dictated by security policies.Where doors are used for the cabinets,they shall have a door perforation of at least 75 percent without compromising t

99、he doors stiffness and strength.This facilitates adequate airflow through the cabinet doors,enabling efficient cooling for the ICT equipment housed within.The openings shall not compromise security.Where required,entry doors on the external side of the containment should be equipped with a lock.The

100、lock can be a mechanical lock.However,electronic locks with monitored alarm contacts are preferred.11.4 Flooring Where the flooring is provided as part of the MDC solution,it shall be static conductive or static dissipative to prevent the potential accumulation of static electricity.The flooring sha

101、ll be smooth,levelled,and anti-slip.The flooring shall be chemically resistant to the chemicals used for cleaning and maintenance.There shall be appropriate sealing between the flooring and the containment structure to prevent air leakage beyond the level specified in this standard.If drains are ins

102、talled,they should incorporate backflow or check valves to prevent air leakage and potential water return.The organization responsible for deploying the MDC must ensure that the floor where the MDC will be placed has adequate load-bearing capacity.This includes accommodating the MDC structure itself

103、 along with all cabinet loading,such as ICT equipment,UPS and batteries.yu_ EPI-MDCS-MODULAR DATA CENTER STANDARD:2023 COPYRIGHT EPI NO DUPLICATION IN PART OR WHOLE WITHOUT PERMISSION OF EPI.Page 19 of 43 11.5 Ceiling The ceiling panels shall be appropriately fire rated(e.g.Class-A fire-rated,UL-94

104、V0,EN ISO 11925-2 or similar)material and comply with all applicable local fire codes.The ceiling panels shall have a light pass rate of more than 95%.Effective sealing between the ceiling and the containment structure is necessary to prevent air leakage beyond the specified level outlined in this s

105、tandard.In cases where an external fire suppression system is employed to address potential fires within the containment system,the panels must possess the capability to automatically open upon the activation of the fire alarm.The mechanism for initiating the panel opening can be either mechanical(e

106、.g.Shape Memory Alloy(SMA)actuator)or electronic(e.g.electromagnetic spring lock actuator).When ceiling panels are activated,i.e.opened,they shall not impede the ability to open cabinet doors and entry doors of the MDC.Preferably,the ceiling panels are resettable.Panels that shrink or have thermal l

107、inks requiring replacement are not desirable.HAC-based MDC solutions can be based on a hot air containment or hot air exhaust principle.In a HAC-based MDC which uses a hot air exhaust principle,having multiple chimneys to exhaust hot air from the contained area is preferable.These chimneys should be

108、 capable of directing hot air from the ICT equipment outside the HAC,either directly into a plenum above or into the ambient environment,or into a heat-capturing system that repurposes the rejected heat.Alternatively,a centralized chimney system can be installed by adding vertical walls above the ca

109、binets between the top of the cabinets and the return air plenum and aisle entry doors.In CAC systems,individual hot air exhausts for each cabinet can be utilized.This approach facilitates direct hot air exhaust into the return plenum,also contributing to lower noise levels outside the MDC structure

110、,as most of the noise remains contained within the solid hot air exhaust structure.Example:Example:Example:Hot Air Containment Centralized Exhaust Individual Exhaust yu_ EPI-MDCS-MODULAR DATA CENTER STANDARD:2023 COPYRIGHT EPI NO DUPLICATION IN PART OR WHOLE WITHOUT PERMISSION OF EPI.Page 20 of 43 1

111、1.6 Entry doors of the MDC Entry doors of the MDC can be either swinging/hinged or sliding doors in either a single or double door configuration.Entry doors shall automatically close by using a mechanical or electronic door closing system.Preferably,doors have a“door open”alarm signaling when a door

112、 or doors are opened too long potentially causing integrity issues of the containment solution.Doors shall have handles,both inside and outside of the containment to allow manual operations when necessary.Door handles can be either recessed/flush door handles or surface mounted.Entry doors shall be

113、adequately sealed to avoid air leakage.Entry doors shall feature clear,see-through tempered safety glass or alternative material that meets all other fire safety requirements,unless security policies dictate otherwise.The doors must be capable of withstanding an air pressure pulse equal to or greate

114、r than that generated by the release of a gaseous-based fire suppression system.Standard door operation shall not obstruct access or servicing of any cabinet or cabinet-based equipment.11.7 Cable and pipe entry points The MDC structure must incorporate appropriately sized entry points designed to ac
