Load; Door Requirements; Minimum Distance Between Components And Nearby Surfaces; Cooling/Fan Requirements - Hitachi Universal Storage Platform VM Installation Planning Manual

Load

Static: Over 500 kg.
Dynamic: Over 900 kg.
• Approximate weight of components:
- Control frame (fully loaded): 238 lbs (108 kg)
- Additional SVP/battery backup chassis (fully loaded): 64 lbs (29
kg)
- Disk chassis (fully loaded): 313 lbs (142 kg)

Door Requirements

Front Door: Not used.
• Each component is covered by a bezel provided by Hitachi Data
Systems. The bezels attach to each component and allow appropriate
air flow intake required for cooling. The front of the rack must not block
air flow.
• You must provide blanking panels to cover all remaining open spaces
on the front side of the rack.
• If the rack must have a front door, the door must open more than 90
degrees to provide adequate access during the installation process and
must not interfere with any lift device that may be used during the
installation. In addition, this front door must have more than 50%
perforation to allow sufficient air flow input.
Rear Door: Required
• Must have more than 50% perforation to allow sufficient air flow
output.
• Must be able to open greater than 90 degrees to provide adequate
access.

Minimum distance between components and nearby surfaces

• Minimum distance required between back side of control frame and rear
door for cabling: 120 mm
• Minimum distance required between back side of disk chassis and rear
door for cabling: 120 mm
• Minimum distance between left side of disk chassis and side panel: 70
mm
• Minimum distance between right side of disk chassis and side panel: 70
mm

Cooling/Fan Requirements

System components include fans to provide the necessary cooling. Air flows
in through the front bezel to the rear of the component and exits via the
perforations in the rear door.
The rack does not need to be equipped with a fan.
