NOTICE
This is a contractual document. It contains important warnings and confers important legal rights and obligations. You are advised to read
it carefully.
It is the responsibility of the customer to assure that all installation preparations are complete and in compliance with Teradata Corporation
specifications and requirements and all applicable national, state, or local codes, regulations, and laws.
SITE PREPARATION
This document contains the information necessary for the preparation of a site conforming to Teradata Corporation specifications.
• It is very important that the site complies with the requirements specified in this document because, once the equipment has been
installed, deficiencies in site preparation or the problems caused by these deficiencies are much more difficult to detect and correct.
• Failure to comply with these requirements or take proper steps to protect equipment against risks identified in this document may
cause serious damage to the equipment and to the customer's business.
• In addition to the need to comply with the requirements specified, electrical wiring and mechanical systems must also comply with
all relevant codes, laws, and regulations.
• It is important that the site be prepared by a customer or his agent who is fully conversant with the special requirements of electronic
equipment.
• The responsibility for ensuring that the site is prepared in compliance with this document remains with the customer.
For information and guidance purposes only, a list is provided, in general terms, of these matters for which the customer is responsible.
This list is not intended to be comprehensive, and in no way modifies, alters, or limits the responsibility of the customer for all aspects of
adequate site preparation.
Teradata staff will be available to answer questions relating to the contents of this document, except where:
• The customer has been notified that a full or partial consultant service is available and/or that Teradata will be willing to undertake a
preliminary or final site survey, and
• The customer shall have entered into a formal contract with Teradata for provision of the same.
No comment, suggestion, or advice offered or not offered about preparation of the site, nor any inspection of the site whether before or after
preparation, is to be taken as approval of the location of the site and equipment, or of its preparation, and Teradata will not be liable in
respect of any comment, suggestion, or advice given by its staff, or in respect of any failure to give advice. Problems caused by a customer’s
failure to meet any of the site prep requirements may result in Teradata:
• Charging the customer for additional services,
• Reclassifying a reported problem priority, and/or
• Being relieved of the obligation to perform services.
Finally, only the customer can know the full extent of damage which may be caused to his business by reason of failure of equipment which
is to be installed. For this reason it is the customer's responsibility to ascertain the extent of any such possible damage to his existing or
planned business, and to effect full insurance in respect of it.
CUSTOMER RESPONSIBILITIES
The customer must do or provide the following:
• When required by Teradata, provide the Teradata customer service representative with appropriate drawings that indicate:
• Location of the equipment
• Site wiring (power and signal, paths and lengths)
• Location of other equipment capable of generating electrical noise, electromagnetic interference, heat, etc.
• Make building alterations necessary to meet wiring and other site requirements.
• Provide and install all communications cables, wall jacks, special connectors, and associated hardware.
• Make sure all applicable codes, regulations, and laws (including, but not limited to, electrical, building, safety, and health) are met.
• Provide and install auxiliary power or other equipment as required.
• Make sure the environmental requirements of the system/unit are met.
• Provide floor coverings and environmental systems that limit or control static electricity build-up and discharge.
AC POWER LINE TRANSIENT PROTECTION
In the process of power distribution, transient electrical energy (including, but not limited to, lightning strikes, intermittent short circuits,
and switching transients) can be introduced on to power lines. Such transient energy can be very damaging to electronic hardware and can
also cause data corruption.
Under these circumstances, Teradata Corporation recommends the use of AC power transient suppressors and data (communication) line
transient suppressors. Such protective devices are intended to guard against power and data line transients that can result in hardware
damage and various system or program errors.
Improvement of any deficiencies in power quality is a customer responsibility. Malfunction and/or component failure as a result of power
quality problems are/is not covered by Teradata Maintenance Agreement. Teradata Corporation accepts no liability for any such occurrence
nor for its consequences.
DATA LINE TRANSIENT PROTECTION
The nature of the transient phenomenon may extend to the data communication lines connected to this equipment. It is the responsibility of
the customer to install and connect a data line transient suppression system to correct or prevent any deficiencies. Malfunction and/or
component failure as a result of data quality problems are/is not covered by the Teradata Maintenance Agreement. Teradata Corporation
accepts no liability for any such occurrence or for its consequences.

Product Description
Cabinet Build Conventions
The placement of the hardware components in a cabinet follows these general cabinet build
conventions:
• 700 cabinets:
• Chassis are loaded, in sequence, from the bottom up.
• All chassis except the top Ethernet switches are loaded from the front of the cabinet,
and accessible from both front and rear of the cabinet. The top Ethernet switches are
loaded and accessible only from the rear of the cabinet.
• Each chassis has a standard position in the cabinet, and is numbered from the bottom up.
• Chassis that are managed over the server management network have assigned chassis
ID numbers. The chassis ID number identifies the chassis by position/type in the
management interface.
• Unmanaged chassis are numbered by position for cabling purposes only. The numbers
do not appear in the management interface as identification of the chassis.

Hardware Installation Guide.
Server Management Network Topology
The server management network enables overall system monitoring and control. It is a
redundant, Ethernet-based network that interconnects all cabinets and the Service
Workstation (SWS)virtual machine (VM).
The server management network consists of two physical networks on separate paths:
• Primary network — for direct management communications of all managed chassis in all
cabinets, through Server Management Web (SMWeb) Services.
• Secondary network — for backup communications of all chassis that support a second
Ethernet connection, through SMWeb Services.
Server Management Network Interface
Server management software runs on each CMIC in the system. One CMIC is designated as
the single operational view (SOV) CMIC. The SOV CMIC hosts the SMWeb Services home
page and provides applications and services for server management on a system.
Access to the SMWeb Services home page is through the customer LAN or the server
management LAN. The server management LAN is a connection between the SOV CMIC
and the Service Workstation (SWS). Teradata Services uses the SWS for service operations.
Note: The level of service depends on the service agreements between Teradata and the
customer.

Disk Storage Interconnect
Nodes and arrays are interconnected into a clique configuration for fault tolerance. If a node
in a clique fails, its tasks are automatically moved over to the other node in the clique. The
other node in the clique has direct access to all drives in the clique. The system continues
running minus the failed node.
Each SAS node has redundant connections to the disk array in its clique. All links are point
to point. The only supported clique configuration for this platform is 2 SAS nodes to 1 disk
array.

Minimum Height
Explanation
Raised floor
61.0 cm (24 in.)
Teradata strongly recommends that the Teradata system be installed on a
raised floor to ensure sufficient cooling air delivery to the entire system. A
conditioned or chilled air delivery system using raised floor as cold air
plenum provides an effective way to deliver cold air to all hardware cabinets
on the floor.
Ceiling
3 m (10 ft)
Recommended height prevents warm air that is exhausted at the rear of the
cabinets from being trapped in the area above the cabinets, and from being
recirculated back into the inlets of the hardware equipment.

Cabinet alignment
Teradata hardware cabinets are designed to take in conditioned supply air or chilled air in
the front, pass it over the internal heat dissipating components, and exhaust it from the rear.
All hardware cabinets must be installed front-to-front (rear-to-rear).
Cold aisle width
A minimum distance of 1.2 m (4 ft)—or two floor tiles—is required in the cold aisles, where
the fronts of two rows of cabinets face each other. Perforated floor panels or floor grills must
fill the cold aisles. To meet the cold air delivery requirements for a Teradata system, wider
aisle width in cold aisles may be necessary to accommodate more perforated floor panels or
floor grills. All of the following must be considered in determining how to meet the
environmental specifications, specifically the recommended temperature and relative
humidity ranges:
•
•
•
cold aisle width
number of perforated tiles in cold aisle
type of perforated floor panels (opening percentage)
Hardware Placement Guidelines for Non-Raised Floor
While Teradata strongly recommends a raised floor environment, non-raised floor
environments do exist, specifically those using the overhead cold air delivery method. In a
raised floor environment, cold air is delivered from bottom to top, and warm exhaust air
rises and tends to stay close to the ceiling. Overhead cold air delivery is more complex and
less efficient due to the potential of downward flowing cold air mixing with rising warm
exhaust air.
The following figure shows the recommended locations of cold air diffusers and return vents.
Placement of diffusers is not flexible, as it is with vented tiles. However, the physics remain
the same. The cooling capacity offered by A/C handlers must be sufficient to remove heat
generated by hardware equipment, with considerations given to heat removal inefficiency.
If installation of a Teradata system on a non-raised floor is required, the site team must
consult with Teradata Global Support Center (GSC) and Engineering. Engineering will
require a detailed site survey and analysis to determine the proper equipment layouts that
meet the stated environmental requirements for the system.

Cables
Cable Management
In-cabinet cable harnesses are used for server management, BYNET, and power. Harness
cables are cut to specific lengths and assembled to accommodate specific breakouts to each
of the chassis in the cabinet. This minimizes the potential for incorrect cabling and the need
for cable dressing.
Each cable in the harness assembly is labeled at both ends.

Delivery and Installation
• The size and weight of a system requires that professional movers and riggers deliver the
crated units.
• Make sure that the correct equipment and adequate help is available to move the system
to its on-site destination.
• Avoid exposing the cabinet to extreme temperature and/or humidity changes when
moving it from the uncrating area to its on-site destination.
• Systems are mounted on casters to facilitate moving. They have adjustable glides to
facilitate leveling in their final installed positions.
• The cabinet is weighted toward the front by the equipment. Roll it backwards, pushing
from the front of the cabinet, to avoid tipping.
• Maximum degree of tip allowed on the side of a single rack: 10° off of vertical.
• If the site requires use of an elevator to move the system into place, verify the load
capacity of the elevator.
• Ensure that the floors along the route to the final installation location can support the
weight of the cabinets, and do not impede their movement. If necessary, have the
customer lay down steel plates to facilitate rolling the cabinets across vented tiles,
carpeting, and similar obstacles.
• If there are any steeply-angled ramps along the installation route, advise the movers.
They may need pulleys.
• Floor vents are not designed to handle the weight of a cabinet. Make sure that the cabinet
can be negotiated around them or have the customer lay down steel plates along the
route.
• Verify that the floor at the site can support the concentrated wheel loading. Be especially
careful with perforated floor tiles in sites with raised floors.

APPENDIX B
Site Power Distribution Planning
AC Input Power Distribution
Dual AC Concept
The system is referred to as a dual AC system because the power subsystem in each cabinet
can accommodate power from two separate power sources.
Each processing/storage cabinet has two AC boxes (one blue AC box and one orange AC
box), providing dedicated inlets for the two power sources. By default, current is shared
between the two AC boxes. If one power source is lost, the current on the AC box connected
to the remaining power source will increase to take over power for the lost source; however,
the system will experience some operational degradation.
Note that power connections to some Ethernet switches are not redundant. A system that
loses operation on some of its power cords will lose operation on Ethernet switches that are
connected to a single power supply. For information about which AC boxes provide power
to which Ethernet switches, see the Cabling and Chassis Ports appendix in the Hardware
Installation Guide for your system.
Site Wiring Options for Dual AC
Dual AC can be implemented at a customer site in one of the following ways:
• Two separate utility power sources
• Two separate circuit breaker panels
• Two site UPSs
Site wiring decisions should be made with an understanding of how the customer will
benefit from the dual AC feature.
Note: A site UPS is not required.
Separate Power Sources
Some customers have two separate sources of AC power. For example, a customer’s site may
receive power from two different power substations. In this case, blue AC boxes can be
connected to one source, and orange AC boxes can be connected to the other source. If the
source supplying one AC box type fails, the current on the other AC box type will increase,
allowing the system to continue operating.
700 Platform Product and Site Preparation Guide
53
Appendix B Site Power Distribution Planning
AC Input Power Distribution
Separate Circuit Breaker Panels
Some customers are concerned about the loss of power to the system during electrical
maintenance work on the site. In this case, the system can be wired so blue AC boxes can be
connected to one circuit breaker panel, and orange AC boxes can be connected to another
circuit breaker panel. If the circuit breaker panel supplying one AC box type is accidentally
shut off, the current on the other AC box type will increase, allowing the system to continue
operating.
Two Site UPSs
Some customers may have two site UPSs. If so, the site can be considered as having two
separate power sources.
System Load Configurations
WARNING: All systems must be wired so that AC lines feeding blue AC boxes and AC lines feeding
orange AC boxes are sized to support the entire system load.
Teradata 700 power subsystems use load sharing by default. Sites can expect an approximate
increase of 100% in load on the active line when the other source of power fails. That is, a
source has 50% of the load to start with, and when AC is lost from the other source, the
remaining 50% of the load transfers to the active source.
Site Wiring for System Integrity
For maximum system integrity, observe the following:
• Rate each AC feed for the rated nameplate current.
• All system components should be on dedicated branch circuits from a distribution panel
that does not supply any switched inductive loads (motors, air conditioners, etc.).
• Nothing else should be connected to the branch circuits except other computer
equipment.
• The socket-outlet shall be installed near the equipment and shall be accessible.

The purpose of site environmental control and preparation (that is, for equipment
placement, floor layout, airflow delivery requirement, and so on) is to meet the
specifications as described in Environmental Requirements. Different data centers may have
different arrangements but still meet the same environmental specifications. However, some
arrangements are more efficient than others in terms of air conditioning (A/C) capacity
usage, A/C operating cost, floor space usage, robustness of hardware equipment during
environmental changes, and so on.
Note: The design of the computer room air conditioning units or other environmental
control systems must ensure that the cooling air at the inlets of individual chassis enclosures
within each hardware cabinet meets the environmental requirements outlined in
Environmental Requirements.

About Cooling Capacity Planning
Cooling capacity planning is imperative to ensure Teradata systems perform at the expected
reliability and availability levels.
Cooling capacity planning starts with Teradata providing heat load estimates of hardware
equipment and ends with the customer supplying sufficient cooling capacity to Teradata
equipment. Customers must provide sufficient cooling to Teradata systems to ensure
Teradata equipment operates within recommended environmental specifications at all
times. See Environmental Requirements.
Use the System Power and Floor Space Estimator to estimate the heat load of a particular
Teradata system. Always use the latest version, as the tool is constantly evolving.
The System Power and Floor Space Estimator is at:
http://gss.td.teradata.com/td_performance/
WhitePapersConfigGuidlines.cfm#ChoosingWhitePaper
The heat load estimates from the Estimator tool must be used, understood, and
communicated with a clear understanding of the following:
Disclaimer
The calculated power consumption levels are estimates only. They typically represent the
worst sustained power consumption levels. The unsustained power consumption levels can
be higher during system power up. The actual power consumption will differ depending on
operating temperatures, applications, etc.
The calculated floor space is also an estimate only. Aisle widths may differ from one data
center to another.
About Cold and Hot Aisles in Floor Layout
The system hardware employs front-to-rear air cooling technology. Cooling air enters the
cabinets through the openings near the bottom of the front doors, and heated air is
exhausted from the rear of the cabinets.
Cold aisles are the aisle spaces between two rows of cabinets that face each other, front to
front. A cabinet row with the front facing open space is also called a cold aisle.
Hot aisles are the aisle spaces between two rows of cabinets that are aligned rear to rear. A
cabinet row with the rear facing open space is also considered a hot aisle.
The cold aisle must remain cold. Do not attempt to cool down hot aisles. They are intended
to be hot, and are not an indication of environment problems. As long as the cold aisles
remain cold, according to environmental requirements, the state of the hot aisles is
irrelevant.

About Aisle Pitch and Tile Cutouts
Following are examples of the recommended locations and shapes of tile cutouts. These
examples facilitate two vented floor tiles (61 cm [24 in.] x 61 cm [24 in.] each) in cold aisles,

Brush seals are strongly recommended for tile cutouts. Tile cutouts need to be cut to the size
and shape that will accommodate the brush seals. The following is a recommended tile
cutout size without consideration of the brush seal:
any inter-cabinet cables
12.7 cm (5 in.) wide
7.6 cm (3 in.) deep
Note: Unblocked tile cutouts will result in chilled air leakage. This may lead to reduced
chilled air supply to hardware equipment through vented tiles, reduced computer room
cooling efficiency, increased use of air conditioning equipment, and increased air
conditioning operating cost.

How to Measure Environmental Elements
Environmental Measurement Instruments
Following are recommendations for handheld digital meters that can measure temperature,
relative humidity, and airflow velocity:
• A Kestrel 4000 or similar flow meter (with memory function to log data points for
predetermined time intervals)
• An Omega HHF81 or similar thermometer
About Measuring Temperature and Humidity
Air temperature and humidity level at the inlet of each chassis inside a cabinet are a true
indication of environmental conditions. It may be difficult to take these measurements at
each chassis, since it requires attachments of multiple probes inside the cabinet with the
door closed.
As an alternative, the temperature and humidity levels at the chassis inlets can be derived by
measurements taken outside the cabinet door, as illustrated in this section.
You can measure temperature and humidity with or without instrument readers.
700 Platform Product and Site Preparation Guide
65
Appendix C Site Environmental Planning
How to Measure Environmental Elements
Without instrument readers
Place temperature and humidity probes approximately 0.64 cm (0.25 in.) in front of
the opening near the bottom of the cabinet's front door.
With instrument readers
If using one of the instrument readers recommended under Environmental
Measurement Instruments, orient the air flow impellers parallel to the door inlet
vents, so that air going into the door opening will pass through the impellers and
sensors.

Cabinet_0041
Humidity measurements taken outside and inside the cabinet door are generally the same.
However, air temperature measurements taken outside and inside the door can differ. To
estimate the maximum air temperature at the chassis inlets inside the cabinet door, the
general rule is to take two readings outside the front door, calculate an average temperature,
then add 5° C (9° F).
Note: Do not take temperature measurements at the rear of the cabinet, facing the hot aisle.
About Measuring Airflow
Air flow meters measure air velocity, in meters per second (m/s) or feet per minute (ft/min).
The measurements for air velocity must then be converted to air flow rate, in cubic meters
per second (m3/s) or cubic feet per minute (ft3/min).
Two methods for measuring air velocity and calculating airflow rate are:
• Using an Alnor meter
• Using an airflow meter and handmade air capture hood
66
700 Platform Product and Site Preparation Guide
Appendix C Site Environmental Planning
How to Measure Environmental Elements
The Alnor flow rate meter is a specialized instrument that can be used to measure air flow
rate. It has an air capture hood, and is instrumented to measure air flow rate in m 3/s or ft3/
min. Once calibrated, it is very accurate. However, the Alnor meter has a list price of more
than $1,200.
A cost-effective method to get reasonably accurate air flow rate measurements is to use a
digital air flow meter and a handmade cardboard air capture hood. The accuracy of the
measurements using the handmade air capture hood depends on the dimensions of the air
hood, specifically the height, the placement of the air flow meter, and the air flow rates.
Typically, measurements obtained using this method, with the height of the hood no less
than 46 cm or 18 in, are accurate within 5-10% of those taken by a calibrated Alnor meter. A
correction factor (CF) representing this discrepancy can be derived for a specific handmade
air capture hood using an Alnor meter as calibration tool.
For detailed information on the recommended flow meter, the dimensions and fabrication
of the hood, and the correction factor, contact your local Teradata Regional Technical
Specialist (RTS), the Teradata Global Support Center (GSC), or Teradata Engineering.
Measuring Air Flow Rate Using an Air Flow Meter and Handmade Air Capture
Hood
This procedure for measuring air flow is specific to a raised floor environment. The air
capture hood can be used to measure flow rate of an overhead air diffuser in an overhead air
delivery environment, as long as the larger open end of the hood can cover the opening of
the diffuser.

2 Place the hood with the large open end over a vented floor tile.
700 Platform Product and Site Preparation Guide
67
Appendix C Site Environmental Planning
Evaluating Environmental Elements Before and After an Installation
Minimize air flow leakage by sealing seams on the hood, and by pressing the hood firmly
against the floor.
3 Hold the air flow meter at the small open end of the hood, in the center, to get a reading
of the air velocity.
4 Convert the air velocity reading to the air flow rate.
The measurement in cubic feet per minute is:
flow rate (ft3/min) = flow velocity (ft/min) x area (1 sq. ft on small open end of hood)
If you need to calculate air flow rate in cubic meters per second (m 3/s), the conversion
factor is 4.719 x 104.
For example, to obtain air flow rate in m3/sec when measured air flow rate is X ft3/min
(CFM), multiply X ft3/min by 4.719 x 104: X x 4.719 x 104.
Evaluating Environmental Elements Before and
After an Installation
Teradata strongly recommends that airflow measurements be performed before and after
equipment installation. As soon as the site for the system installation is confirmed and
accessible, perform the initial airflow evaluation. After the equipment installation is
completed, repeat the airflow evaluation to verify preinstallation measurements.
Additionally, perform temperature and humidity measurements for each cabinet after the
equipment is in production.
Evaluating Air Flow
1 Lay down the vented and cutout tiles according to the floor layout.
See the top box in the figure.
68
700 Platform Product and Site Preparation Guide
Appendix C Site Environmental Planning
Evaluating Environmental Elements Before and After an Installation
2 Request that all dedicated computer room air conditioning (CRAC) units be turned on.
This ensures that airflow characteristics above and below the raised floor are consistent
before and after installation.
3 Measure and record the flow rate of chilled air delivery through every vented tile.
See How to Measure Environmental Elements.
4 Measure and record the flow rates of chilled air leakage through the tile cutouts that do
not have brush seals.
This allows you to understand the extent of the air leakage.
5 Compare the flow rate through vented tiles to the chilled air requirement guidelines.
If the airflow measurements do not meet the environmental requirements, it may be
necessary to rearrange the floor layout.
6 After the equipment installation is completed, as shown in the lower box in the figure,
repeat the air flow measurements to verify pre-installation measurements.
Evaluating Temperature and Humidity
Once the system is in production, take temperature and humidity measurements for each
cabinet, as outlined in About Measuring Temperature and Humidity, to ensure that
environment requirements are met.
Even if all preinstallation requirements are met, it is still possible that hot spots exist in a
data center. Since rearrangement of the cabinets at this point is probably not feasible, it is

to ISO 14644-1 Class 8, which may be achieved simply by specifying the following means of
filtration:
• The room air may be continuously filtered with MERV 8 filters, as recommended by
ASHRAE Standard 127 (ASHRAE 2007).
• Air entering a data center may be filtered with MERV 11 or MERV 13 filters as
recommended by ASHRAE (2009b).
For gaseous contamination, ASHRAE recommends that data center operators maintain an
environment with corrosion rates within the following guideline per ISA-71.04 (ISA 1985):
• Copper reactivity rate of less than 300 Å/month
Further, due to limitations from copper reactivity, ASHRAE recommends the addition of the
following guideline in addition to the above copper reactivity rate:
• Silver reactivity rate of less than 200 Å/month
