Checking the Equipment Room

Checking the Equipment Room

The equipment room for accommodating the storage device must meet associated requirements to ensure the stable running of the storage device. Inspect the equipment room periodically to reduce the possibility of device failures.

Impact on the System

The storage device imposes demanding requirements on the equipment room environment. An unqualified environment impairs the proper running of the storage device.

Tools and Materials

Ensure that the tools and materials required for inspecting the equipment room are available. The required tools include a thermometer, hygrometer, and multimeter.

Reference Standard

Table 9-1 lists the items and standards for inspecting an equipment room.
Table 9-1  Equipment room check items and standards

Check Item

Standard

Temperature

Operating temperature

  • 5°C (41°F) to 40°C (104°F) when the altitude is between -60 m and 1800 m
  • The ambient temperature drops by 1ºC every time the altitude increases by 220 m. when the altitude is between 1800 m and 3000 m

Storage temperature

-40°C (-40°F) to +70°C (158°F)

Humidity

Operating humidity

10% R.H. to 90% R.H.

Storage humidity

5% R.H. to 95% R.H.

Altitude

Operating altitude of disks

  • HDDs: -304.8 m to +3048 m (-999.99 ft. to +9999.99 ft.)
  • SSDs: -305 m to +3048 m (-1000.64 ft. to +9999.99 ft.)

Non-operating altitude of disks

  • HDDs: -305 m to +12192 m (-1000.64 ft. to +39999.51 ft.)
  • SSDs: -305 m to +12192 m (-1000.64 ft. to +39999.51 ft.)

Particle contaminants

ISOa 14664-1 Class8

Corrosive airborne contaminants

  • Copper corrosion rate: less than 300 Åb/month per ANSIc/ISAd-71.04 severity level G1.
  • Silver corrosion rate: less than 200 Åb/month per ANSIc/ISAd-71.04 severity level G1.
  • You are advised to ask a professional organization to monitor the corrosive airborne contaminants in the equipment room.
  • The following is an example of initial evaluation for environmental corrosion risks.
    • Whether the equipment room is near any sulfurous gas emission sources, for example, porcelain factories, rubber plants, tire factories, chemical factories, sewage plants, power stations, paper mills, smelters, automobile factories, coal mines, electroplating factories, food factories, and tanneries? If yes, environmental corrosion risks may exist.
    • Whether the equipment room is near the sea, saline, sewer outlets, sewage treatment tanks, and industrial/heating boilers? If yes, environmental corrosion risks may exist.
    • Whether the equipment room was decorated in the latest six months? If yes, environmental corrosion risks may exist.
    • Whether batteries are stocked in the equipment room? Whether the storage battery leaks? If yes, environmental corrosion risks may exist.
    • Whether the equipment room is closed tightly? Whether the room windows and doors are always closed? If no, environmental corrosion risks may exist.

Procedure

  • Measure the ambient temperature using the thermometer.
  • Measure the ambient humidity using the hygrometer.
  • Measure the ambient altitude.
  • Monitor the particle contaminants in the equipment room by a professional environmental surveillance organization.
  • Verify the power parameters of the equipment room.

Exception Handling

  • If the measured temperature or humidity falls outside the normal range, tune the air conditioners in the equipment room until the temperature or humidity falls within the normal range.
  • If a power parameter fails to meet the standard, append dedicated power lines and a power transformer with sufficient capacity.
