  • Page 25: General Computer Room Requirements

    Make sure your computer room adheres to all national and local building codes for a data center/computer room environment. HP recommends that you follow these general guidelines: • Locate the computer room away from exterior walls of the building to avoid the heat gain from windows and exterior wall surfaces.

  • Page 26: Preventing Electrostatic Discharge

    Fundamental safeguards for disk arrays should include a site well away from any sources of potential damage. If you have any questions on site safety, consult your HP representative, your insurance carrier, and local building inspectors for safety recommendations. Fire safety...

  • Page 28: Raised Floor Requirements

    Raised floor requirements 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.

  • Page 29: Floor Covering

    HP recommends the use of a tiled raised floor. CAUTION: HP strongly discourages the use of carpeting, including antistatic varieties, within 6.0 m (20 ft.) of the disk array. Over time, carpeting may shed dust that can cause problems with the disk array.

  • Page 34: Floor Clearance Calculation Table

    To determine clearance A and clearance B, divide the A+B value between A and B. They do not need to be equal. For example, if the A+B value from the table is 60 cm, then A can be 40 cm and B can be 20, or both A and B can be 30. However, if your configuration includes only a DKC, or a DKC and one DKU, then A must be at least 28 cm (11.1 in) to allow for opening the DKC front door.

  • Page 42: Environmental Requirements

    Environmental requirements The environmental specifications for operating your disk array must be satisfied before installation. Altitude The maximum altitude for disk array operation is 3,000 meters. For nonoperational or storage situations, the maximum altitude is 4,000 meters. Air conditioning 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.

  • Page 44: Humidity Specifications

    Humidity specifications 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. Low humidity contributes to undesirably high levels of electrostatic charges. This increases the electrostatic discharge (ESD) voltage potential.

    Prevent small dust particles from entering the computer room by maintaining its air conditioning system at a high static air pressure level. Your HP representative can help you determine if you need to be concerned about airborne contaminants. Metallic particulate contamination Metallic particulates can be especially harmful around electronic equipment.

  • Page 50: Data Comm Requirements

    A dedicated analog phone line Needed for the HP StorageWorks Continuous Track XP “phone home” feature, if you plan to use it. An HP representative will configure Continuous Track XP during installation. For more information on Continuous Track XP, see the HP StorageWorks XP12000 Disk Array Owner’s Guide.

  • Page 51: Electrical Requirements

    Shifts in AC line frequency can cause system errors. An HP representative can monitor the frequency of the input AC line power and make recommendations, if necessary. The disk array requires that the line frequency be within 0.5 Hz of the rated line frequency (50 Hz or 60 Hz).

  • Page 52: 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.

  • Page 53: Receptacles

    Specific power plugs and receptacles are required for the DKC and DKUs depending on the power option you specify when ordering the HP XP12000 disk array. 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.
  • Page 54 electrical requirements and practices. See Electrical specifications for specific plug and receptacle part numbers and ordering information. 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 and can create a fire hazard.

  • Page 55: Power Line Transients

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

  • Page 56: Uninterruptible Power Supply (Ups)

    CAUTION: This section discusses a product UPS. If you are planning or already have a site-wide UPS, HP recommends against using a product UPS powered by a site-wide UPS for the XP12000. Make sure your UPS satisfies the requirements in the following table. Table values are based on a worst-case voltage (rated voltage –10 percent) and a maximum configuration...

  • Page 57: Sources Of Electrical 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. An HP representative can advise you about the most common causes of electromagnetic interference. HP StorageWorks XP12000 Disk Array...

  • Page 58: Delivery Space Requirements

    Delivery space requirements The delivery area must provide enough space and floor strength to support the packaged equipment cartons for the disk array. Refer to the packaged dimensions in Dimensions and the packaged weights in Weights. CAUTION: Make sure that your doorways and hallways provide enough clearance to move the equipment safely from the delivery area to the computer room.

    4 Delivery and unpacking The disk array equipment is shipped directly from HP. If the disk array is part of a system order, HP coordinates shipment from all HP locations so that all of the equipment arrives at your site at approximately the same time.

  • Page 76: Checking For Shipping Shortage And Damage

    This packaging is used for most shipments within the USA that are direct from the factory to the customer. HP uses special carriers with a dedicated fleet of trucks and specially trained personnel.

  • Page 77: Required Tools

    As you unpack the cartons, match the delivered items to the packing list (invoice) for each carton. Contact your HP SR immediately if any items are missing or are not the ones you ordered. Move all equipment to the computer room before the installation date.
  • Page 78 CAUTION: Any movement of the equipment by forklift should be done prior to unpacking. The carton assembly provides the most secure support of the equipment during movement. Transporting the equipment by forklift after the packaging carton has been removed is not advisable.

  • Page 79: Removing Packaging Materials
