Fire suppressant
disclaimer
“Fire suppressant disclaimer” on page 21
“Floor load-bearing requirements” on page 21
“Transportation and delivery guidelines” on page 24

“Remote support” on page 26
Fire prevention equipment in the computer room should always be
installed as an added safety measure. A fire suppression system is the
responsibility of the customer. Care should be taken by the customer
when selecting appropriate fire suppression equipment and agents
for their data center. Your insurance underwriter, local fire marshal,
and local building inspector are all parties that should be consulted in
selecting a fire suppression system that provides the correct level of
coverage and protection. EMC designs and manufactures equipment
to internal and external standards that require certain environments
for reliable operation. EMC does not make compatibility claims of
any kind nor does EMC provide recommendations on fire
suppression systems. However, if a high pressure gas system is used,
EMC does recommend that storage equipment not be positioned
directly in the path of the gas discharge stream so as to minimize the
forces and vibration during the discharge.
Note: The previous information is provided on an “as is” basis and provides
no representations, warranties, guarantees or obligations on the part of EMC
Corp. This information does not modify the scope of any warranty set forth
in the terms and conditions of the basic purchasing agreement between the
customer and EMC Corp.
Floor load-bearing
requirements
It is recommended but not required that the Symmetrix DMX-3 950
configuration be installed on a raised floor. If the system is installed
in a raised or nonraised floor environment, customer must ensure
that the subfloor or site floor, respectively, is capable of supporting
the system weight specified in Table 10 on page 54.
Symmetrix DMX-3 950 systems presite considerations
21
Physical Planning
If the system is installed in a raised floor environment, customer must
ensure that the raised floor is capable of supporting the system
weight. EMC recommends the use of 24 X 24 inch heavy-duty,
concrete-filled steel floor tiles. If different size or type of tile is used,
customer must ensure that the tiles have a minimum load rating that
is sufficient for supporting the system weight. To ensure proper
physical support of the system, the following requirements, which
are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty,
concrete-filled steel floor tiles, must be complied with:
◆
Floor must be level.
◆
Floor tiles and stringers must be rated for a minimum static load
of 1,600 lbs (725.7 kg) based on two casters of 800 lbs (362.9 kg)
each per tile.
◆
Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg)
rolling load.
◆
Floor tiles and stringers must be rated for a minimum static
ultimate load of at least 3,000 lbs (1,360.8 kg) per tile.
◆
Floor tile deflection must be minimized with additional pedestal
mounts.
◆
Do not position the system bay or storage bays with more than
two casters on a single floor tile.
Note: Cutting tiles per specifications as shown in Figure 6 on page 64 will
ensure the proper caster placement.
22
◆
Use or create no more than one floor tile cutout that is no more
than 8 in. (20.3 cm) wide by 6 in. (15.3) deep in each 24 x 24 in. (61
x 61 cm) floor tile.
◆
Floor tile cutouts will weaken the tile. Therefore, at least one
additional pedestal mount adjacent to the cutout of a tile is
recommended. The number and placement of additional pedestal
mounts relative to a cutout should be in accordance with the tile
manufacturer’s recommendations.
◆
Care should be taken when positioning the bays to make sure that
a caster is not moved into a cutout.
◆
Ensure that the weight of any other objects in the data center does
not compromise the structural integrity of the raised floor or the
subfloor (nonraised floor) of the data center.
EMC Symmetrix DMX-3 950 Physical Planning Guide
Physical Planning
WARNING
Customer must be aware that the load-bearing capacity of the
data center floor is not readily ascertainable through a visual
inspection of the floor and that the only definitive way to ensure
that the floor is capable of supporting the load associated with
the Symmetrix DMX-3 950 storage system is to have a certified
architect or the data center design consultant inspect the
specifications of the floor to ensure that the floor is capable of
supporting the system weight specified in Table 10 on page 54.
Customer is ultimately responsible for ensuring that the floor of
the data center on which the Symmetrix DMX-3 950 system is to
be configured is capable of supporting the system weight,
whether the system is configured directly on the data center floor,
or the system is configured on a raised floor supported by the
data center floor.
Failure to comply with these floor-loading requirements could
result in severe damage to the Symmetrix DMX-3 950 system, the
raised floor, subfloor, site floor and the surrounding
infrastructure should the raised floor, subfloor and/or site floor
fail.
NOTWITHSTANDING ANYTHING TO THE CONTRARY IN
ANY AGREEMENT BETWEEN EMC AND CUSTOMER, EMC
FULLY DISCLAIMS ANY AND ALL LIABILITY FOR ANY
DAMAGE OR INJURY RESULTING FROM CUSTOMER’S
FAILURE TO ENSURE THAT THE RAISED FLOOR, SUBFLOOR
AND/OR SITE FLOOR ARE CAPABLE OF SUPPORTING THE
SYSTEM WEIGHT AS SPECIFIED ABOVE. CUSTOMER
ASSUMES ALL RISK AND LIABILITY ASSOCIATED WITH
SUCH FAILURE.
Symmetrix DMX-3 950 systems presite considerations

Physical Planning
Transportation and
delivery guidelines
Symmetrix DMX-3 950 systems delivered within the United States or
Canada travel by air-ride truck. Each Symmetrix DMX-3 950 system
is shrouded by custom-designed shipping material, crated, and
palletized.
Symmetrix DMX-3 950 systems delivered internationally normally
involve air freight. Unless otherwise instructed, the EMC Traffic
Department arranges for delivery directly to the customer’s
computer room. To ensure successful delivery of Symmetrix DMX-3
950 systems, EMC has formed partnerships with specially selected
moving companies. These companies have moving professionals
trained in the proper handling of large, sensitive systems. These
companies provide the appropriate personnel, floor layments, and
any ancillary moving equipment required to facilitate delivery.
Data center preparation for DMX-3 950 system delivery
The following are considerations that must be taken into account
prior to the delivery of the DMX-3 950 system at your site:
!
CAUTION
Inform EMC of any labor union-based restrictions or security clearance
requirements prior to delivery.
◆
Weight capacities of the loading dock.
◆
Weight capacities for tailgate.
◆
Length of covering required for floor protection.
◆
Weight capacities for service elevator if delivery is to another
floor.
◆
Equipment ramp needed if the receiving floor is not level with
computer room floor.
Note: All portions of the bay shall clear ramp and threshold slopes up to
1:10 (rise to run ratio), per Code of Federal Regulations – ADA Standards
for Accessible Design, 28 CFR Part 36.

Environmental
acclimation
The DMX-3 950 system requires a period of time to become
acclimated to a data center environment. Follow the acclimation
process to prepare the DMX-3 950 system for the data center that is
described in “Environmental acclimation” on page 57.
Note: Temperature and humidity values experienced by the system must be
such that condensation does not occur on any system part. Altitude and
atmospheric pressure specifications are referenced to a standard day at 58.7°F
(14.8°C). Maximum wet bulb temperature is 82°F (28°C).
Layout and space
recommendations
Layout and space considerations are found in Chapter 4, “System
Placement,”.
WARNING
Before the Symmetrix DMX-3 950 bays are rolled into position in the
computer room, note how close the wheels are to the edge of the
cutout. If the Symmetrix system needs to be relocated, contact the
EMC Customer Support Center. For access floor-tile load
requirements, refer to Table 10 on page 54.
!
CAUTION
When moving the storage bay down an incline, the rear of the
cabinet must go first.
When moving the storage bay up an incline, the rear of the bay
goes last.
Note: If a raised floor environment is used, 12 inches (30 cm) to 24 in. (60 cm)
raised floor clearance for power cables and host cabling is recommended.
System host cabling
requirements
The Presite Survey completed with the EMC Systems Engineer
reports the cable lengths (Fibre Channel or serial) required for each
host connection to the Symmetrix system. From a physical planning
perspective, review the routing path(s) from the host(s) to the
Symmetrix DMX-3 950 system. Resolve any physical access issues
before the installation day.
Note: If host cables are run from overhead, a top cable management bracket,
Model number DMX3-CBL BRKT, must be used.

Remote support
Remote support is an important and integral part of EMC’s customer
service and support strategy. Communication between the EMC
Customer Support Center and the Symmetrix DMX-3 950 system
occurs through the external serial modem connected to the
Symmetrix service processor.
Note: This feature requires customers to provide a dedicated direct dial-up
phone line for the modem (for remote support) within six feet (two meters) of
the system bay.

Additional installation considerations
The following options can be considered for current and future
upgrade planning. Contact your EMC Sales representative for more
information.
DMX-3 950 system
securing kit
Some customers require that their EMC equipment be installed to
withstand significant shock and vibration. Installation of EMC
Symmetrix DMX-3 950 systems securing kits in combination with
adequate substrate construction will mitigate collateral damage
during such events.
DMX-3 950 Silencer
The Symmetrix DMX-3 950 Silencer is a fan noise reduction option for
the Symmetrix DMX-3 950 system bay and storage bays. The
Symmetrix DMX-3 950 Silencer is designed with leading edge sound
reducing materials that attenuate high-frequency noise components
and reduce overall sound levels. It is designed not to affect airflow or
thermal performance.
Planning for
upgrades
When planning for upgrades, consider space, power, and
environmental concerns.

precautions
When connecting Fibre Channel channels to host channels, it is
important to familiarize yourself with the Symmetrix DMX-3 950
Fibre Channel hardware components and their channel designations.
Each Symmetrix Fibre Channel director occupies one slot on the
Symmetrix DMX-3 950 backplane. Each director interfaces to the host
channels through a FEBE board in the backplane card cage. The
Symmetrix Fibre Channel directors contain four advanced
microprocessors. Refer to Figure 5 on page 39 for the FEBE board port
designations and “FEBE board/ channel director configurations” on
page 40.

EMC Products are designed to be consistent with the requirements of
the American Society of Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE) Environmental Standard Handbook and the
most current revision of Thermal Guidelines for Data Processing
Environments, Second Edition, ASHRAE 2009b.
The Symmetrix DMX Series systems are best suited for Class 1
Datacom environments, which consist of tightly controlled
environmental parameters, including temperature, dew point,
relative humidity, and air quality. These facilities house mission
critical equipment and are typically fault tolerant, including the air
conditioners.
The data center should maintain a cleanliness level as identified in
ISO 14664-1, class 8 for particulate dust and pollution control. The air
entering the Data Center should be filtered with a MERV 11 filter or
better.
Environmental data
55
Physical and Environmental Specifications
The air within the Data Center should be continuously filtered with a
MERV 8 or better filtration system. In addition, efforts should be
maintained to prevent conductive particles, such as zinc whiskers,
from entering the facility.
The allowable relative humidity level is 20-80% non condensing,
however, the recommended operating environment range is 40-55%.
For Data Centers with gaseous contamination, such as high sulfur
content, lower temperatures and humidity are recommended to
minimize the risk of hardware corrosion and degradation. In general,
the humidity fluctuations within the Data Center should be
minimized. It is also recommended that the Data Center be positively
pressured and have air curtains on entry ways to prevent outside air
contaminants and humidity from entering the facility.
For facilities below 40% relative humidity (RH), it is recommended to
use grounding straps when contacting the equipment to avoid the
risk of Electrostatic discharge (ESD), which can harm electronic
equipment.
As part of an ongoing monitoring process for the corrosiveness of the
environment, it is recommended to place copper and silver coupons
(per ISA 71.04-1985, Section 6.1 Reactivity) in airstreams
representative of those in the data center. The monthly reactivity rate
of the coupons should be less than 300 Angstroms. When monitored
reactivity rate is exceeded, the coupon should be analyzed for
material species and a corrective mitigation process put in place.

The DMX-3 950 system requires a period of time to become
acclimated to a data center environment. Use the following process to
prepare the system for the data center:
1. Completely remove all packing material from the system.
Packaged accessory (that is, Open First) boxes may remain with
the system.
2. Dispose of the packing materials appropriately.
3. Move the system into its operating environment and allow the
system to stabilize in the new environment for up to 16 hours as
listed in Table 15 on page 58. If the operating system
environments temperature and humidity are unknown then
allow the system to stabilize in the new environment for 16
hours.
4. EMC recommends opening both the front and rear doors of the
system to facilitate environmental stabilization.
5. Do not apply AC power to the system for at least the number of
hours specified in Table 15 on page 58.

System Placement
This chapter covers the physical placement options that are available
for the DMX-3 950 system:
◆
Placement options .............................................................................. 62
System Placement
61
System Placement
Placement options
The Symmetrix DMX-3 950 configurations can be installed in several
different flooring environments. The system can be installed on a
solid floor or raised floor environment. Although it is not required,
the raised floor environment is the preferred installation
environment.
When planning the DMX-3 950 system placement, EMC recommends
positioning the system bay frame first so that the closed front door
aligns with the floor tile edge. The storage bay frame is then aligned
with the system bay frame and are bolted together later. When the
system bay and all the storage bay doors are closed, the system bay is
slightly recessed in relation to the storage bay because the depth of
the system bay door is less than the depth of the storage bay doors.
Floor load-bearing
requirements
It is recommended but not required that the Symmetrix DMX-3 950
configuration be installed on a raised floor.
If the system is installed in a raised or nonraised floor environment,
customer must ensure that the subfloor or site floor, respectively, is
capable of supporting the system weight specified in Table 10 on
page 54.
If the system is installed in a raised floor environment, customer must
ensure that the raised floor is capable of supporting the system
weight. EMC recommends the use of 24 X 24 in. heavy-duty,
concrete-filled steel floor tiles. If different size or type of tile is used,
customer must ensure that the tiles have a minimum load rating that
is sufficient for supporting the system weight. To ensure proper
physical support of the system, the following requirements, which
are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty,
concrete-filled steel floor tiles, must be complied with:
62
◆
Floor must be level.
◆
Floor tiles and stringers must be rated for a minimum static load
of 1,600 lbs (725.7 kg) based on two casters of 800 lbs (362.9 kg)
each per tile.
◆
Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg)
rolling load.
◆
Floor tiles and stringers must be rated for a minimum static
ultimate load of at least 3,000 lbs (1,360.8 kg) per tile.
◆
Floor tile deflection must be minimized with additional pedestal
mounts.
EMC Symmetrix DMX-3 950 Physical Planning Guide
System Placement
◆
Do not position the system bay or storage bays with more than
two casters on a single floor tile.
Note: Cutting tiles per specifications as shown in Figure 6 on page 64 will
ensure the proper caster placement.
◆
Use or create no more than one floor tile cutout that is no more
than 8 in. (20.3 cm) wide by 6 in. (15.3) deep in each 24 x 24 in. (61
x 61 cm) floor tile.
◆
Floor tile cutouts will weaken the tile. Therefore, at least one
additional pedestal mount adjacent to the cutout of a tile is
recommended. The number and placement of additional pedestal
mounts relative to a cutout should be in accordance with the tile
manufacturer’s recommendations.
◆
Care should be taken when positioning the bays to make sure that
a caster is not moved into a cutout.
◆
Ensure that the weight of any other objects in the data center does
not compromise the structural integrity of the raised floor and/or
the subfloor (nonraised floor) of the data center.
WARNING
Customer must be aware that the load-bearing capacity of the
data center floor is not readily ascertainable through a visual
inspection of the floor and that the only definitive way to ensure
that the floor is capable of supporting the load associated with
the Symmetrix DMX-3 950 storage system is to have a certified
architect or the data center design consultant inspect the
specifications of the floor to ensure that the floor is capable of
supporting the system weight specified in Table 10 on page 54.
Customer is ultimately responsible for ensuring that the floor of
the data center on which the Symmetrix DMX-3 950 system is to
be configured is capable of supporting the system weight,
whether the system is configured directly on the data center floor,
or the system is configured on a raised floor supported by the
data center floor.
Failure to comply with these floor-loading requirements could
result in severe damage to the Symmetrix DMX-3 950 system, the
raised floor, subfloor, site floor and the surrounding
infrastructure should the raised floor, subfloor and/or site floor
fail.

requirements
The Symmetrix DMX-3 950 system requires two dedicated and
isolated AC power feeds that plug directly into the PDPs of the bays.
Before delivery, the customer must supply and install the required
receptacles on two separate power distribution units (PDUs) for zone
A and zone B power for the Symmetrix DMX-3 950 system bay and
optional expansion storage bay. DMX-3 950 power redundancy can
only be assured at the customer PDU and after. Figure 10 on page 69
shows examples of labels attached to each power cable exiting the
Symmetrix DMX-3 950 system bay and optional expansion storage

CAUTION
The Symmetrix DMX-3 950 power supplies should not be
connected on the separate Main and Auxiliary circuit panels to
differential trip devices. These devices are typically called GFCI
(Ground Fault Circuit Interrupter), GFI (Ground Fault Interrupter),
ELCB (Earth Leakage Circuit Breaker), or Residual Current Circuit
Breakers.
The Symmetrix DMX-3 950 system is designated as fixed (stationary)
electrical equipment with high earth-leakage markings. The intention
is to connect the cabinets to the customer AC supply with the
recommended rated current breakers (refer to “Electrical
specifications and power requirements” on page 74 for
recommended circuit breaker ratings) and the attached cables. These
recommended breaker ratings are based on the maximum kW
loading of the cabinet and not on the KVA figures of a particular
configuration. The KVA values listed in this manual (refer to “Power
and cooling data” on page 59) are intended for air conditioning and
utility loading purposes only.
Because the Symmetrix DMX-3 950 system is a high earth-leakage
device, differential trip devices (typically 30 mA) are not
recommended due to random activations during utility feed
distortions and powerline transients interacting with the cabinet
noise filters.
These differential devices can be called GFCIs, GFIs, ELCB, or other
names, but typically have trip ratings of 5 mA to 500 mA and are
mostly intended for consumer goods rather than fixed devices.
If the Symmetrix cabinet is correctly grounded to the customer’s AC
power source, leakage current should not produce a voltage leading
to electrical shock. Serious insulation breakdowns should trip the
breakers feeding the cabinet or, preferably, should first clear fuses in
individual internal modules closest to the fault.
Symmetrix DMX-3 950 power overview
71
Power Requirements
Regulatory
compliance
The Symmetrix DMX-3 950 system meets regulatory requirements as
referenced by the following UL/IEC/EN 60950 3d Edition:
5.1.7 Equipment with touch (leakage) current exceeding 3.5mA
For Stationary Permanently Connected Equipment, or Stationary
Pluggable Equipment Type B, having a main protective earthing
terminal, if the Touch (Leakage) Current measurements exceed 3.5mA
r.m.s., following conditions apply:
• The r.m.s. Protective Conductor Current will not exceed
five percent of the input current per line under normal
operating conditions. If the load is unbalanced, the largest of
the three-line (phase) currents shall be used for this
calculation.
To measure the Protective Conductor Current, the procedure
for measuring Touch Current is used, but the measuring
instrument is replaced by an ammeter of negligible
impedance.
• The cross-sectional area of the Protective Bonding Conductor
will not be less than 1.0 mm squared in the path of high
Protective Conductor Current.
• A label with similar wording shall be affixed adjacent to the
equipment AC MAINS SUPPLY connection:
HIGH LEAKAGE CURRENT
Earth connection essential
before connecting supply.
The Symmetrix DMX-3 950 configurations are Stationary Pluggable
Type B systems, and have been extensively tested and certified to
meet the above standard, including the application of the warning
label, EMC P/N 046-000-309, in English and French. The label
location for the Symmetrix DMX-3 950 configuration is on the inside
of the front door.

EMC Symmetrix DMX-3 950 Physical Planning Guide
Power Requirements
Choosing a UPS
The Symmetrix DMX-3 950 is capable of supporting two consecutive
five minute power outages before its battery backup unit is depleted.
To extend this time period, purchase a UPS from a qualified vendor.
EMC neither offers nor recommends any specific UPS suppliers or
product type for its customers. However, EMC uses preferred
suppliers for UPS systems in their facilities. Therefore, if you, the
customer, are implementing a UPS, EMC recommends the following:
◆
When you are planning the UPS solution for the Symmetrix
system and the host system is presently (or will potentially be)
protected with a UPS, the battery backup time you propose for
the Symmetrix UPS solution should match that of the host
system.
◆
The Symmetrix system requires independent zone B and zone A
power feeds for each bay.
◆
The UPS should be equipped with an internal output isolation
transformer.
◆
The UPS should be installed as a separately derived AC source
using neutral and ground wiring to preserve the (2N) fault
tolerance specification of the Symmetrix power system.
◆
Depending on the power requirements for your Symmetrix
system operation, an isolation transformer/stabilizer installed in
front of the UPS could further buffer the AC utility environmental
factors from reaching the Symmetrix system. To determine if an
isolation transformer/stabilizer is needed, consult a licensed
electrician.
