Cabinet component of a Data Center design
2
In support of the IT function we construct Data
Centers but often seem to lose site of whole
design in the specifications of individual items.
The Cabinet has been viewed both as a necessary
evil and the potential savior, in reality it is
simply a component of the total design.

• Cabinet (enclosure) Considerations
• Cabinets for the Data Center, not multi-purpose.
• Industry standard best practices for the data
  center EIA-310, TIA-942, etc.
• Provide options for the four major issues facing
  the IT professional today and in the future.
• Four Primary Issues in the Data Center Cabinets
• Ventilation
• Cabling
• Power
• Security

4
Two basic cabinet styles. The OEM /equivalent
cabinet, and newer best practice oriented
frame. Each Cabinet system typically supports the
four key areas of Cable Management, Ventilation,
Power and Security. The traditional OEM style
approach adds components external to the design
in a building block fashion. Typical cabinet
design. The best practice oriented approach
seeks to incorporate more cable and structural
features into the basic frame design following a
best practice approach.
5
The issues of ventilation, power, cable
management and access control are interconnected
with each supporting or impeding the other. Basic
OEM cabinets typically provide minimal
considerations to the four interconnected issues.
Advanced frames are designed to minimize the
impact and improve the interrelated performance.
Cable Management can block airflow
Support requires instant access but Management
wants control
Power can interfere with cable access and airflow
Poor design can limit both airflow and hot cold
aisle benefits
6
Cabinet Ventilation
Increased density in server cabinets has led to
increased heat. Maintaining the proper air volume
delivery required by the watts generated can be a
greater issue than cooling the exhaust air.

• Issues and Concerns for the Cabinet
  Component
• Best Practice Hot and Cold Aisle
• Cable routing to prevent bypass air
• Maintaining Hot-Cold air separation within the
  cabinet plates, seals
• Need for new door designs to increased air flow
• Provide an IEC 310-D Compliant Cabinet
• Provide an ASHRAE TC9.9 Compliant Cabinet

Cabinet Ventilation
Recommended Best Practice for Ventilation

• Server OEMs recommend
• 64 open area mesh front and rear doors
• Solid steel top, end panels
• Hot-Cold aisle configurations
• Blanking plates
• No Additional Fans
• The Uptime Institute recommends
• Hot-cold aisle configurations
• Blanking Plates
• Floor level grommets

8
Cabinet Ventilation
Recommended Best Practice for Ventilation

• ASHRAE TC9.9 Committee recommends
• Server inlet temperature recommended 68 to 72
  degrees
• _at_ 55 relative humidity
• Hot cold aisle configurations
• Cold aisle- One perforated floor tile in front
  of each cabinet
• Hot aisle Minimum of three feet
• Blanking plates

Maximize the separation between hot and cold air
9
CFM is more important than air temperature!!!

• cfm 3.16 x watt / ?T(ºF)
• ?T(ºF) 18ºF 10ºC
• All air cooled servers cool themselves
• Ability to remove heat is dependant on the
  volume of free air (cfm) available to each server.

10
Cabinet Ventilation Best practice
11
Cabinet Ventilation

• True 180 Degree Hinge Door Max Ventilation plus
  Max Access
• Maximum available mesh area
• Complete access to equipment
• Clear aisle

12
Cabinet Ventilation
Door Components Increased mesh sizes Door
configuration/frame Open area width vs. mesh
13
Cabinet Ventilation Alternative
Beyond the best practice Hot-Cold aisle cabinets
can be fitted with supplemental systems like the
Liebert XDV.
14
SMC Cabinets Cable Management
Increasing numbers of cable runs and new sizes
continue to affect cable access and air flow in
both Server and Telecom cabinets.

• Issues and Concerns for the Cabinet Component
• Switches moving into Server areas
• Multiple NIC (Network Interface Card) cards
• RILO (Remote Insight Lights-Out) cards
• KVM (Keyboard Video Mouse)
• Increased volume with CAT 6 (larger O.D.)
• Continued use and expansion of Fiber
• Impact on airflow
• Poor design and placement by OEM (Cable
  Management arms, Cisco R to L Venting)
• Accessibility for changes

Cabinet Cable Management
Vertical Patch Panel System to limit cable volume
behind the server
17
Cabinet Cable Management
Complies with Cisco Ventilation and Cable
requirements
18
Cabinet Power
The additional server density leads to increased
power loads per square foot in every cabinet
requiring more mounting points to serve an
increasing number of circuits.

• Issues and Concerns for the cabinet
  component
• Increased number of circuits per cabinet
• 208 single phase delivered to the cabinet
• 208 three phase delivered to the cabinet
• Increased Power redundancy to meet tier III and
  IV
• Manage power through information

19
Cabinet Power management
A 24 frame with extension allows four dual
circuits and cable management without blocking
air flow.
Dual circuit PDU

Cabinet Power Management
Integrated Power Distribution
IPD reduces the powers runs under the raised
floor moving the branch circuits above the raised
floor
21
Cabinet Managed Access
Continued up-time requirements and an increase in
shared resources has placed pressure on activity
policies inside the secure data center room and
is creating audit trail requirements.

• Managed Activity/Reporting (Security)
• CoLocation Inter-company resource sharing,
  reporting
• HIPPA- new levels of access control
• Sarbanes Oxley new levels of audits and
  reporting
• Inability to maintain policy
• Control access at door level
• Provide true default to close
• Ability to audit actions

22
Cabinet Managed Access
Managed access is not security but a system for
managing and reporting activity at the cabinet
level
23
Cabinet Managed Access

• The Cabinet should provide cabinet level security
  not handle level security.
• Design defaults to close, maintains a reportable
  continuity.
• Provides reporting to support continuity

24
Cabinet Managed Access
Compliments the best practice polices for access
and reporting in a secure area

• Date and Time of action
• The location of the asset and the name of the
  asset
• The action taken
• The company and individual taking the action
