Site Safety Consideration

When making decisions con cerning si te safety, your first concer n should be
the safety of your personnel and then the safety of your equipment. Two
major safety considerations for any computer site are fire safety and
emergency po wer-of f. If you hav e any quest ions on si te safety, consult your
HP CE, your insurance carrier, and local building inspectors for safety
recommendations.

Fire Safety

When considering fire safety, consult your insurance carrier and fire
department for suggestions and recommendations. They can analyze your
existing fire control systems, and advise you of any changes that may be
needed. If you are building a new site, or modifying an old site, consult
your local building co des for fire pre vention and protectio n guideline s. You
can also consult your local HP CE and local fire inspectors for additional
information.

Equipment Servicing Hazards

You and your HP CEs and HP ASEs require safe access to the disk array.

Along with the specifications listed in “General Computer Room
Requirements” (page 19), ensure that electrical or data communication

HP SureStore E Disk Array XP512: Site Prep Guide

General Computer Room Requirements

The goal of a computer room is to maintain an ideal environment for your
computer equipment, including your HP SureStore E Disk Array XP512.
The following guidelines are recommended:

• Locate the computer ro om aw ay f rom ext er io r wal ls of th e bui ld ing to
avoid the heat gain fr om windows and exterior wall surfaces.

• When exterior wi ndows a re unavoidable, use windows that ar e double
or tripled glazed and shaded to prevent direct sunlight from entering
the computer room.

• Maintain the computer room at a positiv e pressure relative to the
surrounding spaces to reduce introduction of contaminants.

• Use a vapor barrier installed around the entire computer room
envelope to restrain moisture migration.

• Caulk and vapor-seal all pipes and cables that penetrate the envelope.

• Use a 10-inch to 12-inch raised floor system for the most favorable
room air distribution system.

Space planning

Preparing for Installation

A site prep begins with your existing floor plan. The location of the new
equipment should be selected and a new floor plan should be developed.

HP SureStore E Disk Array XP512: Site Prep Guide

Service and Cable Routing Space Requirements

This section contains information about space requirements for the HP
SureStore E Disk Array XP512. Thi s data should be used as a guideli ne f or
space planning development.

The service clearance is the additional flooring space required to access
your HP SureSto re E Dis k Ar ray XP512. This space should be reserved for
the disk array; never use this space for storage.

HP recommends that you prepare a revised floor plan showing the overall
location and a rr ange ment of your computer room, including t he addition of
your disk array. Enough room and lightin g should be pr ovided for people to
work effectively on a da ily basis and for periodic servicing of equipment.

Select a location that ca n accommoda te the a dditi on of more DKU cabinet s
as your requirements increase. Be sure to consider interconnecting cables
and power cord leng ths when planning your layout. Identif y t he location of
all power outlets on the floor plan. Plan to keep cables away from traffic
areas to help prevent accident s and equipment fai lures. Prior to ins tallat ion,
consult your site specialist responsible for your computer room.

Preparing for Installation

HP strongly discou rages th e use of c arpetin g, includi ng anti- static var ieties,
within 6.0 m (20 ft.) of the disk array. If this advice is not foll owed, you
should place stat ic dischar ge mats where per sonnel must walk across befor e
touching any part of the array. Failure to comply with this prec aution can
result in equipment damage through static discharge.

If you are planning to construc t a new computer room or modify an exi sting
site, first consult with your HP representatives and local contractors. It is
important to plan the site with future expansion in mind so that equipment
can be added without disturbing the computer-systems operation.

The computer room floor must be able to support the total weight of the
equipment as well as localized weight at each caster or foot of the
equipment cabinets. A common method of preparing an adequate floor for
a computer room is to co nstru ct a ra ised f loor ov er the buildi ng flo or. The
weight should be spread evenly and the fl ooring should provide an area

27

through which interconnecting cables can be run conveniently and
unobtrusively, and allows optimum distribution of conditioned air. Raised
floor access ramps must not exceed 10

° slope.

To estimate floor strength, the following items should be considered:

• The total weight of the equipment (the unpacked and packaged
weights are listed in this chapter)

• The total weight of furniture such as desks, chairs, and storage
cabinets

• Total approximate weight of computer room personnel

• Weight of moving equipment such as forklifts, dollies, and so on.

Any questions regarding the adequacy of airflow construction should be
referred to and evaluated by a qualified structural engineer.

Caution

In addition to determining the adequacy of the computer site floor, ensure
that all floors, stairs, and elevators which might be used when the disk
array is moved to its destination can support the weight and size of the
equipment. Failure to comply can result in damage to the equipment.

Maximum point floor loading is 500kg (1102.3 lbs). The minimum service
access is:

rear: 800m (31.5 in)

side: 0 mm

front: 800m (31.5 in)

Data Comm Requirements

Route data communications cables away from areas of high static electric
fields created by power transformers and heavy foot traffic. Use shielded
data comm cables that meet approved industrial standards to reduce the
effects of external fields.

Phone Home With Continuous Track

The HP SureStore E Disk Array XP512 Phone Home capabilities detect
and report problems even before they are noticed by operators and users.

Continuous Track, a program that resides in the DKC, will phone “home”
to HP Stres-Free Central control center and will provide:

• periodic “well” checkups

Every 24 hours, Continuous Track will call HP Stress-Free Central.
When a successful conn ection is ma de, a preconfigur ed set of fil es will
be transferred from the DKC to the HP Stress-Free Central control
center. Your HP CE will set the time of call and set up the files to be
transferred. This check-up ensures the health of your disk array, on a
day-to-day basis.

38

• incidental “sick” calls

When an error occurs, a service information message (SIM) is
generated. The SIM is stored in the DKC for use by your HP service
representa tive. The Con tinuous Track remote maintenance tool also
reports the SIMs to the HP Stress-Free Central control center. SIMs
are classified according to severity, and many SIMs do not require
immediate attention. These SIMs are often addressed during routine
maintenance, and are corrected before a failure occurs. Serious-level
and acute-level SIMs are reported to HP Stress-Free Central
immediately to ensure that the problem is addressed as soon as
possible.

To activate Phone Home, these requirements are necessary:

• dedicated analog phone line

• an HP CE to configure Continuous Track

HP SureStore E Disk Array XP512: Site Prep Guide

Local Area Network (LAN)

Remote Control XP and Your Private LAN

HP SureStore E Remote Control XP is a software application that permits
you to connect to, monitor, and manage up to 8 disk arrays. It
communicates directly with the DKC of each attached disk array. The
software runs on a PC called a remote console. The remote console is
attached over a special private LAN. The private LAN is dedicated to the
remote console, and is not used for any other purpose. There are two ways
to connect your HP SureStore E Disk Array XP512 to the private LAN:

• via the private LAN port in the DKC

If you are using HP Remote Control XP to manag e the local dis k array
only, then your CE will connect your remote console PC directly to
your HP SureStore E Disk Array XP512, using the internal LAN port
included in your DKC. Refer to your HP Remote Contr ol XP manual
for PC requirements.

Preparing for Installation

LAN Hardware needed: One twisted-pair LAN cable

HP SureStore E Disk Array XP512: Site Prep Guide

Electrical Requirements

Power requirements are one of the most important considerations prior to
installing your disk array. Each disk array has two separate connections to
AC power, so the rated AC current should be doubled. In case one input
fails, the second input MUST BE CAPABLE OF SUPPORTING THE
ENTIRE CURRENT DEMAND FOR BOTH SETS OF POWER
SUPPLIES.

Line Voltage

The line voltage (AC) at the wall power outlet is a function of the local
power utility and your building power distribution network. Voltages
outside the operating range of the disk array can cause intermittent system
errors or a complete system shutdown. If required, the HP CE along with
your electrician can determine the current line voltage and make
recommendations. Avoid the use of a line voltage conditioner.

Make sure that dis tribution u nit s upports the c orrect v oltage t o support your
entire system.

Branch Circuit Breakers

Three-Phase Branch Circuit Breakers

The power cord supplied with each DKU is sized for connection to a 30­amp circuit. This specification per phase is based on the input power
requirements of the first DKU in the subsystem since the first DKU
supplies power to the DKC.

Single-Phase Branch Circuit Breakers

With the single-phase power option, both the DKU and the DKC are
connected to the AC main. The power cord supplied with the DKU and
each DKU is sized for connection to a 20-amp circuit.

Preparing for Installation

41

Frequency

AC line frequency is normally determined by your local power providers.
In some cases, electrical power is supplied by motor-generators. Shifts in
AC line frequency can cause system errors. Your HP CE can monitor the
frequency of the input AC line power and make recommendations, if
necessary.

Safety and Dedicated Ground

The primary reason for grounding electrical systems is safety. The safety
ground is required by the National Elec tric Code (USA) and most other
local, regional, and national codes. In addition to safety ground, HP
requires that a dedica te d (eart h refer ence) gro und be in stall ed as a common
reference point for all system components. You should consult with your
HP CE and your electrician to ensure that your electrical system meets all
local and national safety codes.

HP SureStore E Disk Array XP512 Grounding Requirements

Your subsystem must meet all of the following conditions:

• An insulated grounding conductor that is identical in size and
insulation material and thickness to the ungrounded branch-circuit
supply conductors. It should be green, with or without yellow stripes,
and is to be installed as a part of the branch circuit that supplies the
unit or system.

• The grounding conductor mentioned above should be grounded to
earth at the service equipment or other acceptable building earth
ground such as the building frames (in case of a high rise steel-frame
structure).

44

HP SureStore E Disk Array XP512: Site Prep Guide

Receptacles

When receptacles are used to connect your disk array components to AC
power, they must include a dedicated ground connection that is insulated
from the receptacle . It is important that the recep tacle box be groun ded with
an additional ground connection that is nondedicated. The additional
ground can be hard conduit.

Each disk array has two separate connections to AC power, and the second
input must be capab le of supporting the entire current demand f or bot h s ets
of power supplies.

When installing the r ec ept acl es, make sure that each r ece pta cl e has it s own
neutral (if required) and ground. Using the same neutral/ground for more
than one circuit will cause voltage loss, heat problems, and can result in a
fire hazard. A shared neutral conductor that fails open-circuit will result in
possible over-voltage damage to equipment.

For 3-phase 60Hz operation, the outlet must be either:

• Connector Russell & Stoll 3934 or

• Receptacle Russell & Stoll 3754

The plug type provided with the power cord is a

• Russell & Stoll 3760

• Russell & Stoll 3760PDG

Power Line Transients

Heavy electrical loads from nearby machinery or equipment (elevators,
electric welders, etc.) can cause intermittent system errors, even if that
equipment is on a separate circuit breaker. When faced with these
conditions, you should provide a separate, completely independent power
panel with an isolated ground and circuit breaker coming directly from the
main building power source or secondary power source.

Preparing for Installation

45

If necessary, your HP CE can measure your power line noise level and
make appropriate recommendations concerning the use of line treatment
devices.

Maximum Peak Inrush and Crest Factor

The inrush current for the HP SureStore E Disk Array XP512 is:

3-Phase

60 amps fo r the first DK U
25 amps for 2nd DKU

Single-Phase

50 amps fo r the first DK U
40 amps for DKC

Crest Factor

The crest-factor for the HP SureStore E Disk Array XP512 is 1.68.

46

HP SureStore E Disk Array XP512: Site Prep Guide

Sources of Electrical Interference

Ensure that the disk array is protected from sources of electrical
interference:

wall outlets Convenience power outlets for building maintenance

equipment (vacuum cleaners, floor buffers, etc.) must
be wired from circuit breakers on a power panel
separate from the computer system panel. The ground
wires from these outlets must be connected to the
normal building di stributio n panel and n ot to the s ystem
ground.

If a separate power source and separate ground are not
provided, operation of janitorial equipment can induce
electric noise and cause abnormal operation of the
computer system. Your electrician can verify whether
or not maintenance outlets are on separate panels.

lightning In some geographical areas it may by advisable to

install lightning protection for both personnel and
computer systems.

Preparing for Installation

The principles of lightning protection and personnel
safety are outlined in detail in the lightning protection
code contained in the National Fire Protection
Association (NFPA) Handbook.

vibration Continuous vibration can cause a slow degradation of

mechanical parts and, when severe, can cause data
errors in disk drives. Mechanical connections such as
printed circuit assembly (PCA) conductors, cable
connectors, and pr ocesso r ba ckpla ne wiri ng can also b e
affected by vibrations.

electromagnetic int erference

The disk array is specifically designed to reduce its
susceptibility to radiated and conducte d interference.
Electromagnetic interference can cause a variety of
system problems. Your HP CE can advi se you about

47

many of the most common causes of electromagnetic
interference.

metal If metal is used in the construction of the raised floor,

ensure that there is a common ground connection
between the raised floor and main floor to avoid
possible build up of di fferen t voltage pot ential s. Failure
to comply can result in serious injury to personnel and
damage to equipment.

flammable materia ls

Fundamental safeguards for disk arrays should include
a site well away from any sources of potential damage.
The system should not be installed or operated in an
environment where there is a risk of fire or explosion
due to the presence of highly flammable gases, volatile
liquids, or combustible dust.

airborne contaminants

Airborne contaminants and particles of a certain size
and hardness can damage you r disk a rrays. Some of t he
most common contaminants are dust, smoke, ash,
eraser debris, food crumbs, and salty air.

48

Your HP CE can assist you in determining whether or
not you need be concerned about airborne
contaminants.

Uninterruptible Power Supply (UPS)

Most HP SureStore E Disk Array XP512 units are installed in data centers
where an uninterruptible power system (UPS) strategy is already in place.
However, if you are making your first large disk array purchase, you may
have a need for a separate UPS solution. HP references the Silcon DP300
series UPS solution. The Silcon DP300 is product from American Power
Conversion Corp (APC), manufacturers of uninterruptible power systems.

UPS Features

The APC UPS, Silcon DP300 series, provides the following feature set:

• Protection agains t short line transient s

• Continued availability during short duration power failures (A
minimum of 30 minutes for a fully-configured system)

• Stable AC output voltage

UPS Limitations

• LCD display unit with ability to display key AC input/output
parameters, alarm log, events log and programming functions

• Communications Interface option for communicating a remote UPS
shutdown through the serial port connection.

While the UPS will provide uninterru pted power to the XP array in the
event of a power failure, once the battery runtime is exceeded, it will shut
down, resulting in a loss of AC power to the array. The UPS does have the
ability to communicate an oncoming shutdown to the host via the Silcon
Triple Chas sis. The host can then p ass t his mes sag e in- band to the XP arra y
using the “xppf” program.

Environmental Requirements

The environmental specification for operating your disk array must be
satisfied prior to installation.

Air Conditioning Ducts

Use separate computer room air co nditioning duc t work. If i t is not se parate
from the rest of the building, it might be difficult to control cooling and air
pressure levels. Duct work seals are important for maintaining a balanced
air conditioning system and high static air pressure . Adequate cooling
capacity means little if the direction Humidity levels may increase if the
ducts are exposed to warm air.

Humidity

Maintain proper humidity levels. High humidity levels causes galvanic
actions to occur between some dissimilar metals. This eventually causes a
high resistance between connections, leading to equipment failure.

60

Caution

Low humidity contributes to undesirably high levels of electrostatic
charges . Th is i ncreases the electr ost atic disch arge (ESD) voltage potential .
ESD can cause component damage during servicing operations.

Static charges (voltage levels) occur when objects are separated or rubbed
together. The voltage level of a static charge is determined by the following
factors:

• types of materials

• relative humidity

• rate of change or separation

HP SureStore E Disk Array XP512: Site Prep Guide

Follow these precautions to minimize possible ESD-induced failures in
your computer room:

• Install conductive flooring (conductive adhesive must be used when
laying tile s).

• Use conductive wax if waxed floors are installed.

• Ensure that all equipment and flooring are properly grou nded and ar at
the same ground potential.

• Use conductive tables and chairs.

• Store spar e electric parts in antistatic containers.

• Maintain recommended hum idity level an airflow rates.

Low humidity levels are often the res ult of the facility heati ng system and
occur during the cold season. Most heating systems provide air with a low
humidity level, unless the system has a built-in humidifie r.

Dust and Pollution Control

For troublefree operation, disk drives require a dust-free environment, The
HP SureStore E Disk Array XP512 disk drive is protected from dust
particles by mechanical air filters designed to trap large dust particles.
Smaller particles can pass through some filters, and, over a period of time,
can cause problems in mechanical parts. Small dust particles ca n be
prevented from entering the computer room by maintaining its air
conditioning system at a high static air pressure level.

HP SureStore E Disk Array XP512 Temperature and Humidity
Specifications

When the disk array is operating, the recommended temperature range is
21°C to 24°C and recommended relative humidity range to be (at 22
between 50 to 55 percent. The following table lists the temperature,
humidity, and vibration specifications for the HP SureStore E Disk Array
XP512. The vibration and shock specifications apply to all three axes.
