Site preparation

The delivery and installation site for the storage system must meet certain requirements to ensure successful and efficient installation of the storage system.

NoteThe following information is provided to assist in installation planning and is not intended to be complete. The installation and maintenance documents used by Hitachi Vantara personnel contain complete specifications. For further information about site preparation for storage system installation, contact customer support.

Site preparation checklist

Verify the availability of each item in the site preparation checklist.

The responsibilities for installation planning are shared by the customer and the Hitachi Vantara account team. The required installation planning tasks must be scheduled and completed to ensure successful and efficient installation of the storage system.

The following tasks might take several weeks to complete:

  • Acquiring required power outlets.
  • Adding or modifying air conditioning systems.
  • Making room alterations to accommodate the storage system.
  • Ordering third-party equipment, such as non-Hitachi racks, network switches, and host servers for the storage system.

Use the following checklist to prepare for installation of the storage system.

RequirementYes No
Is the data center free of any equipment servicing hazards, such as electrical or data cables that obstruct access?
Does the data center have a suppression system?
Does the floor plan meet the service clearance and cutout requirements?
Does the floor meet the load rating requirements?
Does the data center meet the environmental requirements including temperature, humidity, airflow, and acoustic?
Is all equipment not supplied by Hitachi (for example, connectors, receptacles, and network switches) on site and ready for use?
Are the input circuit breakers adequate for equipment loads?
Are uninterruptible power supplies (UPS) in place?
Have all sources of electrical interference been addressed?
Does the site enforce access controls (for example, will Hitachi representatives need an escort)?
Will the equipment fit through all doors and corridors and in elevators?

Site planning

All planning activities should be scheduled and completed before the equipment is delivered.

The planning process includes:

  • Planning hardware configuration, such as system component layout in the rack and drive allocation.
  • Planning for specific network topologies, cabling configurations, network switches, and cabling of connected host computers.
  • Ensuring all cables for specific controller and drive tray configurations are properly ordered.
  • Verifying all electrical service wiring is installed at the predetermined location.

Complete the suggested tasks before receiving and installing the storage system:

  • Prepare a preliminary layout of the installation.
  • Review the power and the heating, ventilation, and air-conditioning requirements before ordering any additional support equipment.
  • Make a final layout of the installation and review the layout with the Hitachi Vantara representative.
  • Verify the installation of electrical service wiring at the predetermined location is proper before installing the storage system.
  • Verify all additional equipment, such as switches and host computers, is installed and operational.

Installation site considerations

When planning and preparing for the installation of a storage system, consider the following:

  • The delivery area must provide enough space and floor strength to support the packaged equipment cartons for the storage system. Doorways and hallways must provide enough clearance to move the equipment safely from the delivery area to the destination.
  • The computer room must have sufficient space to accommodate the storage system and other necessary equipment and provide minimum clearance around the storage system for service access and to verify proper weight distribution on the computer room floor. It must also include correctly positioned floor cutouts for the storage system's power and data cables.
  • If the storage system arrives in hot or cold weather or you notice any condensation, do not unpack it until it has been allowed to reach room temperature or the condensation to clear (one to two hours). Immediately exposing the storage system to warm temperature can cause condensation to occur, which could damage the electronics. Maintain recommended humidity level and airflow rates.
  • Take the necessary precautions to prevent electrostatic discharge (ESD). Verify that all equipment and flooring are grounded. Store spare electric parts in antistatic bags until you are ready to install them. When handling the storage system, wear protective devices like wrist straps, sole grounders, and conductive shoes.
  • Proper environmental conditions for the storage system must be maintained. For optimal performance, storage systems require controlled environmental conditions that are often best facilitated through raised flooring and under-floor air conditioning. It is the responsibility of the customer to monitor this environment and ensure continued conformance with the recommended environmental specifications.
  • The computer room must have adequate power facilities for the storage system. Adequate power is necessary to ensure reliable functioning of electronic equipment and for the safety of the customer's installation. The customer is responsible for procuring, installing, and maintaining adequate power to the equipment.

Floor cutout and service clearance

Be sure your site has sufficient space to accommodate the storage system.

When preparing the space required for your storage system, be sure the site:

  • Is large enough to hold the new storage system and other equipment.
  • Provides minimum clearance around the storage system for service access and to verify proper weight distribution on the computer room floor.
  • Includes correctly positioned floor cutouts for the storage system's power and data cables.

To verify there is sufficient space for the storage system, document your site's floor plan, including the locations of:

  • Structural support columns and other immovable objects
  • Walls
  • All existing equipment, cabinets, racks, networking equipment, and other systems
  • Where the new storage system will be installed
  • Floor and electrical cutouts
  • Interconnecting cables and power cords, including lengths
  • Floor vents

The space requirements must take into consideration the total floor clearance required for the storage system. This includes:

  • The space required by the equipment
  • Service clearance - the floor space required to access the storage system.
  • Additional space required to distribute the equipment weight on your computer room's raised floor. The amount of additional space required depends on your floor load rating.
  • Additional space required to view the storage system LEDs on the front and rear panels.

If your computer room uses floor cutouts to route power and data cables, position the cutouts toward the center of the rack. If this is not possible, position the cutouts off-center from the rack as long as the cutout is within the allowable range and allows smooth routing and entrance of cables. Check the relationship between the position of the cutout and the cable openings on the rack.

Floor load rating

The floor space at the installation site must support the combined weight of all associated component and equipment. The maximum load rating is 709 kg.

Installing anti-tilt bracket for Universal V3 Rack

The anti-tilt bracket for the Hitachi Universal V3 Rack must be anchored to a rigid floor capable of holding a minimum of 79 kg (154 lbs).

Before you begin

To install the anti-tilt bracket, use the following tools and components.

  • T25 screwdriver
  • Customer-supplied M10 or 3/8-inch screw capable of holding a minumum 79 kg (154 lbs)

Procedure

  1. Adjust the four retractable feet so the rack is level with the floor.
