3 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.
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.
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.
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 both XP1024 and XP512 DKUs are used, the disk array can have one or two XP1024 DKUs (on one side of the DKC) and one to three XP512 DKUs (on the other side of the DKC) as shown in the figure below. XP1024 and XP512 DKUs cannot be mixed on the same side of the DKC.

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. Space planning 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.
The minimum service access is: • Rear: 800 mm (31.5 in) • Side:: 0 mm • Front: 800 mm (31.5 in) Floor loading In addition to the minimum clearance required for servicing, the computer room floor may need additional clearance and requires proper construction to support the total weight of the equipment as well as the 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 figure below shows the recommended service clearance and floor cutout recommendations for the XP1024 DKC. Measurements are in millimeters.

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.
HP StorageWorks XP Remote Web Console and Comand View AE HP StorageWorks Remote Web Console (RWC) is a web-based software application supplied with the XP1024 disk array that permits you to connect to, monitor, and manage the array. For managing multiple XP disk arrays, you can upgrade to the optional Command View XP Advanced Edition (CVXP AE) which also runs in a web browser.
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.
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. Branch circuit breakers See “AC power cabling requirements” on page 53 for the specific branch circuit requirements for your power situation.
The following tables reflect the line voltage for each power cable when the cabinets are cabled with functioning, redundant power cables. AC line voltage requirements for the HP Disk Array XP1024 DKC The table below lists the basic AC power requirements for a 40-amp, single-phase XP1024 DKC.

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.
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).
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.
The Russelstoll connectors are available through most industrial electrical distributors. HP has arranged for these connectors to also be available in stock from the distributors listed below. These distributors are able to ship worldwide and ship via customer preference.

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.
electromagnetic interference 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.
AC power cabling requirements Four types of AC power cabling, depending on your location, are specified under the following headings: • “Three-phase AC cabling for the USA (60 Hz)” on page 54 • “Three-phase AC cabling for Europe (50 Hz)” on page 58 • “Single-phase AC cabling for USA” on page 61 • “Single-phase cabling for Europe” on page 65 See the power cabling section that applies to your location and available power.
Three-phase AC cabling for the USA (60 Hz) Each three-phase HP Disk Array XP1024 DKU has two main disconnect devices (two main breakers for dual power lines) so that AC power to the unit can be supplied from separate power distribution panels with two power-supply cords. Warning Trained service personnel should be present whenever the disk array is being connected to a new power source for the first time. Incorrect power connections can cause equipment damage and possible injury or death to personnel.

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.
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.
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 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.

4 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.
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.
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.
