Site planning timetable

The following guidelines can be used to monitor the progress of your preinstallation preparation. The time between placing an order to actual arrival can vary, and we recommend conferring with your HP representative to determine the best estimated delivery dates for preparation of your site.

The following are items that may require several weeks of lead time to complete:

• Acquiring required power connectors

• Arranging for an electrician

• Adding or modifying air conditioning

• Building alterations

• Placing an order for data comm equipment

Due to potential delays, we recommend that the suppliers of the listed services be contacted as soon as you have placed your order:

• Schedule the site planning visit with your HP CE to discuss questions concerning site planning.

• Select an appropriate location for the disk array and create a plan outlining the physical arrangement of the equipment, including related furniture.

Preparing for installation

This chapter provides information for planning and preparing your site before and during installation of your HP Disk Array XP1024.

Before installing your HP Disk Array XP1024, your site data center computer room must meet the requirements described in this chapter.

19

Safety requirements

The following sections contain information to help you properly prepare your facility for the arrival of your disk array.

Site safety consideration

When making decisions concerning site safety, your first concern 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 power-off. If you have any questions on site 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 codes for fire prevention and protection guidelines. You can also consult your local HP CE and local fire inspectors for additional information.

Equipment servicing hazards

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

Along with the specifications listed in “General computer room requirements” (page 21) , ensure that electrical or data communication

cables do not create a safety hazard.

20

HP StorageWorks Disk Array XP1024: Site Preparation Guide

General computer room requirements

The goal of a computer room is to maintain an ideal environment for your computer equipment, including your HP Disk Array XP1024. The following guidelines are recommended:

• Locate the computer room away from exterior walls of the building to avoid the heat gain from windows and exterior wall surfaces.

• When locating near exterior windows is unavoidable, use windows that are double or tripled glazed and shaded to prevent direct sunlight from entering the computer room.

• Maintain the computer room at a positive 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 if the under floor area is being used as an as part of the air circulation system.

Space planning

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.

You can use this section to satisfy the disk array physical requirements, ensuring that your site is ready when the disk array arrives. Your floor plan should include the location of:

• Walls

• Cable paths, including lengths

• All equipment in your computer room, including furniture, cabinets, racks, data comm equipment, and systems

• Electrical outlets

• Immovable objects

• Floor vents

Preparing for installation

The HP Disk Array XP1024

Your HP Disk Array XP1024 is a high-performance disk array system. It is used to store large quantities of data in an efficient and secure manner. The components of the HP Disk Array XP1024 are contained in one of two types of cabinets.

Each HP Disk Array XP1024 has one disk controller cabinet (DKC), which contains the controller electronics for the disk array, and one to five disk-cabinet units (DKUs), which contain the hard disk drives.

When only XP1024 DKUs are used, the disk array can have one to four

XP1024 DKUs. The figure below shows a Disk Array XP1024 with four

XP1024 DKUs.When both XP1024 and XP512 DKUs are used, the DKU types cannot be mixed on the same side of the DKC.

HP StorageWorks Disk Array XP1024: Site Preparation Guide

Service and cable routing space requirements

This section contains information about space requirements for the HP Disk

Array XP1024. This data should be used as a guideline for space planning development.

The service clearance is the additional flooring space required to access your HP Disk Array XP1024. 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 arrangement of your computer room, including the addition of your disk array. Enough room and lighting should be provided for people to work effectively on a daily basis and for periodic servicing of equipment.

Select a location that can accommodate the addition of more DKU cabinets as your requirements increase. Be sure to consider interconnecting cables and power cord lengths when planning your layout. Identify the location of all power outlets on the floor plan. Plan to keep cables away from traffic areas to help prevent accidents and equipment failures. Prior to installation, consult your site specialist responsible for your computer room.

HP strongly discourages the use of carpeting, including anti-static varieties, within 6.0 m (20 ft.) of the disk array. If this advice is not followed, you should place static discharge mats where personnel must walk across before touching any part of the array. Failure to comply with this precaution can result in equipment damage through static discharge.

If you are planning to construct a new computer room or modify an existing 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 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 construct a raised floor over the building floor. The weight should be spread evenly and the flooring should provide an area

Preparing for installation

29

30 through which interconnecting cables can be run conveniently and unobtrusively. It should allow for optimum distribution of conditioned air.

Raised floor access ramps must not exceed a 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.

The minimum service access is:

• Rear: 800 mm (31.5 in)

• Side:: 0 mm

• Front: 800 mm (31.5 in)

Maximum point floor loading is 500 kg (1102.3 lb).

The floor cutout should be planned in the center of the DKC. In case that the floor cutout is planned

may be off-center.

In this case,check the relation between the positions of the cutout and the opening on the bottom of

the frame.

If the floor cutout width is planned more than 520 mm,be careful about the restriction of the movable

direction because there is a possibility that the caster wheels fall down into the cutout.

Actual clearances for installation should be decided after consulting with construction specialist responsible for installation building, as they could vary depending on the size/layout of the system and building conditions.

When various configurations of subsystems are arranged in a row, clearance values based on the largest subsystem should be used.

From the viewpoint of maintenance operations, it is suggested that clearance (c) be made as large possible.

Data comm requirements

Route data comm 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 Disk Array XP1024 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, phones “home” to the HP

Storage Technology Center (STC) and provides:

Periodic “well” checkups

Every 24 hours, Continuous Track calls the HP Storage Technology

Center. When a successful connection is made, status and/or configuration information is transferred from the DKC to the HP

Storage Technology Center. Your HP CE sets the time of the call. This checkup records the health of your disk array on a daily basis.

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 representative. The Continuous Track remote maintenance tool also reports the SIMs to the STC. 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 the

STC 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 StorageWorks Command View XP and your public Intranet

HP StorageWorks Command View XP is a web-based software application that permits you to connect to, monitor, and manage disk arrays. You can remotely manage your HP Disk Array XP1024.

Local Area Network (LAN)

To connect to your Intranet (public LAN), your CE directly connects your

HP Disk Array XP1024 to an available Ethernet port on your public LAN.

To ensure network security, consult with your HP CE and your network administrator before selecting the location of your LAN drop.

Network Hardware Needed:

• One twisted pair (Cat 5) cable

• Ane available LAN drop on your Intranet

Outside phone line

Recommendation

Install a public voice phone line near your disk array. This phone line is used by you and your HP CE for voice communication in and outside of your facility.

37

Electrical requirements

Power requirements are one of the most important considerations prior to installing your disk array. For disk array cabinets with two connections to

AC power, if one input fails, the second input must be capable of supporting the entire current demand nominally shared by the two power connections. For disk array cabinets with four connections to AC power, the two connections to AC Box 1 or the two power connections to AC Box

2 must be capable of supporting the entire current demand nominally shared by the four power connections. The figure below shows two examples of the disk array’s fault-tolerant operation.

The Disk Array can tolerate the loss of connections to AC Box 1 or AC Box 2, but no other combinations are allowed.

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

38

HP StorageWorks Disk Array XP1024: Site Preparation Guide

Branch Circuit Breakers

See “Branch Circuit Requirements”

(page 39)

for the specific branch circuit requirements for your power situation.

Three-phase branch circuit breakers

The power cords supplied with each HP Disk Array XP1024 DKU configured for three-phase power are sized for connection to a 30 or

60-amp circuit. There are no external power cords for the DKC when the

HP Disk Array XP1024 is configured for 60-amp, three-phase power.

Single-phase branch circuit breakers

The power cords supplied with each HP Disk Array XP1024 DKU configured for single-phase power are sized for connection to a 30 or

50-amp circuit. The power cords supplied with each HP Disk Array

XP1024 DKC configured for single-phase power are sized for connection to a 30 or 40-amp circuit.

30-amp, single-phase power is available by special order only.

Frequency

your electrician can determine the current line voltage and make recommendations. Avoid the use of a line voltage conditioner.

Make sure that a power distribution unit (if used) supports the correct voltage to support your entire system.

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. The HP Disk Array XP1024 requires that the line frequency be within 0.5 Hz of the rated line frequency (50 Hz or 60 Hz).

Safety and dedicated ground

The primary reason for grounding electrical systems is safety. The safety ground is required by the National Electric Code (USA) and most other local, regional, and national codes. In addition to safety ground, HP requires that a dedicated (earth reference) ground be installed 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.

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. This means the ground conductor must be run in the same conduit, armored cable, or other cable bundle as the phase wires.

• Grounding as prescribed by your local country codes.

• 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 the case of a high rise steel frame structure).

• IT configured grounding systems are not certified for use with the

XP1024 as these grounding systems may not have solidly conductor-connected grounded power systems and/or they may have resistive impedance inserted in ground and/or neutral lines. The

XP1024 requires a solidly conductor-connected ground and may require a separate neutral in the case of WYE or STAR connections.

48

HP StorageWorks Disk Array XP1024: Site Preparation 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 receptacle box be grounded with an additional ground connection that is separate from the dedicated ground.

The additional ground can be hard conduit.

Each disk array cabinet has two or four separate connections to AC power

(except the 60-amp, three-phase DKC, which has no external power connection). For disk array cabinets with two connections to AC power, each input must be capable of supporting the entire current demand for the cabinet. For disk array cabinets with four connections to AC power, the two inputs to AC Box 1 or the two inputs to AC Box 2 must be capable of supporting the entire current demand for the cabinet. The figure below shows two examples of the disk array’s fault-tolerant operation.

50

Specific power plugs and receptacles are required for the XP1024 DKC and

DKUs, depending on the power option you specify when ordering the HP

Disk Array XP1024. The power cords on 60 Hz cabinets are shipped with plugs attached and connected. The power cords on 50 Hz cabinets are shipped without plugs. Customers are responsible for having the correct plugs and receptacles installed by an electrician in compliance with local electrical requirements and practices.

Caution

When installing the receptacles, the electrician must ensure that each receptacle has its own neutral (if required) and ground. Using the same neutral/ground for more than one circuit causes voltage loss and heat problems. It can create a fire hazard. A shared neutral conductor that fails open-circuit can cause overvoltage damage to equipment.

Power line transients

Heavy electrical loads from nearby machinery or equipment (elevators, electric welders, etc.) can cause intermittent system problems with sophisticated electronic equipment, 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.

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

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 distribution panel and not to the system ground.

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

lightning vibration

In some geographical areas it may by advisable to install lightning protection for both personnel and computer systems.

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.

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 processor backplane wiring can also be affected by vibrations.

Preparing for installation

54 electromagnetic interference metal flammable materials airborne contaminants

The disk array is specifically designed to reduce its susceptibility to radiated and conducted interference.

Electromagnetic interference can cause a variety of system problems. Your HP CE can advise you about many of the most common causes of electromagnetic interference.

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 different voltage potentials.

Failure to comply can result in serious injury to personnel and damage to equipment.

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 and particles of a certain size and hardness can damage your disk arrays. Some of the most common contaminants are dust, smoke, ash, eraser debris, food crumbs, and salty air.

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

Uninterruptible Power Supply (UPS)

Caution

This uninterruptible power system (UPS) reference is for a product UPS situation. If you are planning or already have a site wide UPS,

Hewlett-Packard recommends against a product UPS powered by a site-wide UPS for the XP1024

Most HP Disk Array XP1024 units are installed in data centers where a

UPS strategy is already in place. However, if you are making your first large disk array purchase, you may need a separate UPS solution. HP references the Silcon DP300 series UPS solution, a product of American

Power Conversion Corp (APC), manufacturers of uninterruptible power systems.

UPS features

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

• Protection against short line transients

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

• Stable AC output voltage

• 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

UPS limitations

While the UPS provides uninterrupted power to the XP array in the event of a power failure, once the battery runtime is exceeded, it shuts 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

Chassis. The host can then pass this message in-band to the XP array using the “xppf” program.

HP StorageWorks Disk Array XP1024: Site Preparation Guide

Environmental requirements

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

If you intend to use HP Disk Array XP512 DKUs with your HP XP1024

Disk Array, see the HP StorageWorks Disk Array XP512 Site Preparation

Guide for environmental requirements for these DKUs.

Air conditioning ducts

Use separate computer room air conditioning duct work. If it is not separate 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 increase when the ducts are exposed to warm air.

Humidity

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

Caution

Low humidity contributes to undesirably high levels of electrostatic charges. This increases the electrostatic discharge (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

Preparing for installation

69

70

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

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

• Use conductive wax if waxed floors are installed.

• Ensure that all equipment and flooring are properly grounded and are at the same ground potential.

• Use conductive tables and chairs.

• Store spare electric parts in antistatic containers.

• Maintain recommended humidity level an airflow rates.

Low humidity levels are often the result of the facility heating system and occur during the cold season. Most heating systems provide air with a low humidity level, unless the system has a built-in humidifier.

Dust and pollution control

For trouble free operation, disk drives require a dust-free environment. The

HP Disk Array XP1024 disk drives are 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 can be prevented from entering the computer room by maintaining its air conditioning system at a high static air pressure level.

Metallic particulate contamination

Metallic particulates can be especially harmful around electronic equipment. This type of contamination may enter the data center environment from a variety of source, including but not limited to raised floor tiles, worn air conditioning part, heating ducts, rotor brushes in vacuum cleaners, or print component wear. Because metallic particulates conduct electricity, they have an increased potential for creating short circuits in electronic equipment.This problem is aggravated by the increasingly dense circuitry of electronic equipment.

Over time, very fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin surfaces. If these whiskers are disturbed, they may break

HP StorageWorks Disk Array XP1024: Site Preparation Guide

off and become airborne, possibly causing failures or operational interruptions. For over 50 years, the electronics industry has been aware of the relatively rare but possible threat posed by metallic particulate contamination. During recent years, a growing concern has developed in computer rooms where these conductive contaminants are formed on the bottom of some raised floor tiles.

Although this problem is relatively rare, it may be an issue within your computer room. Since metallic contamination can cause permanent or intermittent failures on your electronic equipment, Hewlett-Packard strongly recommends that your site be evaluated for metallic particulate contamination before the installation of electronic equipment.

Receiving your HP Disk Array XP1024

Your HP Disk Array XP1024 is shipped directly from HP. If your disk array is part of a system order, HP coordinates the shipment of equipment from all locations so that it arrives at your site at approximately the same time.

In some cases, factors beyond the control of HP can cause delivery delays.

If you have not received your equipment within a two week period, notify your HP sales representative. The HP sales representative traces your order and expedites delivery.

Caution

Be sure to allow for size and weight in regards to placing the disk array at

its installation site. Refer to “Dimensions” (page 24) for specific size and

weight values.

Checking for shipping shortage and damage

As your disk array arrives, check the carrier’s bill of lading carefully to ensure that all items shipped by HP are delivered. Notify the carrier immediately if there are any discrepancies or items missing.

Inspect all of the shipping containers for signs of damage before actually unpacking the equipment. Some typical signs of shipping damage are dents, scratches, cuts, or water marks. If any damage is found, note on the bill of lading that there is apparent damage subject to inspection. Arrange for the carrier’s representative and a representative from Hewlett-Packard to be present when the item in question is unpacked.

Regardless of the circumstances, the HP CE takes immediate action to replace any damaged components without waiting for the settlement of claims.

Unpacking the cartons

The equipment cartons can be unpacked at your convenience; it is your responsibility to have the equipment unpacked and moved to its proper installation location prior to the day of installation.

The DKC and DKU frames are very heavy. In a maximum configuration, the DKU weighs more than 1600 lb. It is recommended that three (3) people unpack and move this equipment to avoid injury.

Retain the packing list (invoice) for each carton that is to be unpacked and ensure that each item on the list can be accounted for. Contact your HP sales representative immediately if there are any missing items, or if the items are not the same as you ordered.

Leave the sealed cartons or packages of CDs, cables, and any other installation hardware intact for the HP CE. Your HP CE and HP ASE install and configure your disk array.

Glossary

ACP

AL

AL-PA allocation array group

Glossary

Array control processor. The ACP handles the passing of data between the cache and the physical drives held in the DKUs. ACPs work in pairs, providing a total of eight SCSI buses. Each SCSI bus associated with one

ACP is paired with a SCSI bus on the other ACP pair element. In the event of an ACP failure, the redundant ACP takes control. Both ACPs work together sharing the load.

Arbitrated loop.

Arbitrated loop physical address.

The ratio of allocated storage capacity versus total capacity as a percentage.

“Allocated storage” refers to those LDEVs that have paths assigned to them. The allocated storage capacity is the sum of the storage of these

LDEVs. Total capacity refers to the sum of the capacity of all LDEVs on the disk array.

A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 2d+2d array groups are made up of 4 HDDs. A RAID1 4d+4d group is two 4 HDD array groups concatenated together. RAID5 array groups are made up of 4 or 8 HDDs, depending on whether they are RAID5 3d+1p or RAID5 7d+1p, respectively. All RAID6 array groups are made up of 8 HDDs.

Cache.

Very high speed memory that is used to speed I/O transaction time. All reads and writes to the XP array family are sent to the cache. The data is buffered there until the transfer to/from physical disks (with slower data throughput) is complete.

The benefit of cache memory is that it speeds I/O throughput to the application. The larger the cache size, the greater amount of data buffering can occur and the greater throughput to the applications.

XP arrays support a range of cache memory. In the event of power loss, battery power allows the contents of the cache boards to survive for up to

48 hours.

A RAID Level is one of the ways that disk drives are grouped together in a

RAID to improve performance, data availability/reliability or both. RAID levels are defined from RAID0 to RAID6. HP StorageWorks Disk Arrays in the XP product family support RAID1, RAID5 and RAID6. Not all of these RAID levels are supported by all XP family members. Consult the owner's guide or your HP representative for the details of which RAID levels are supported by your specific XP disk array.
