Checking the Operating Environment of the Storage Device
Check that the operating environment in which the storage device works meets associated requirements to ensure stable running of the device.
Check Method
This section describes how to check the equipment room environment. Checking the equipment room helps the maintenance personnel know the environment conditions and detect potential environment risks to prevent device faults due to environment issues.
Storage devices require a reliable operating environment. Usually, they are installed in a dedicated equipment room with a dedicated air-conditioning system and a redundant power system. Table 4-1 lists the environment check items. For the check criteria, see Check Criteria.
Item |
Check Method |
|---|---|
Temperature, humidity, and altitude |
Read the thermometer, and hygrometer, and barometer in the equipment room. |
Vibration and shock |
Hire a professional organization to measure the vibration and shock on the storage system when it is working or stored. |
Particle contaminants |
Hire a professional organization to monitor the particle contaminants in the equipment room. |
Corrosive gas contaminants |
Hire a professional organization to monitor the corrosive gas contaminants in the equipment room. |
Internal rack environment |
|
Troubleshooting
- 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 the power supply system fails to meet the standard, append dedicated power lines and a power transformer with sufficient capacity.
Check Criteria
This section describes the criteria for checking the storage system's operating environment.
Equipment Operating Environment
Environment requirements cover temperature, humidity, particle contaminants, corrosive airborne contaminants, heat dissipation, and noise.
For details, see section Environmental Requirements in the Product Description of the corresponding product model.
Checking Racks
Properly installed racks of the storage device help ensure the stable and long-term running of the storage device. Check rack conditions periodically to reduce device failure possibilities.
Impact on the System
The storage device imposes demanding requirements on rack conditions. An improperly installed rack impairs the proper running of the storage device.
Tools and Materials
Ensure that the tools and materials for checking rack conditions are available. The required tools include binding straps, an electroprobe, and a multimeter.
Reference Standard
Table 4-2 lists the items and standards for checking rack conditions.
Check Item |
Standard |
|---|---|
General layout of cables |
Power cables (with strong electrical current) and service cables (with weak electrical current) lay on different sides of a rack. |
Layout of power cables |
Power cables are laid out orderly and arranged in a similar manner to power cables on other racks. |
Layout of service cables |
Service cables are laid out orderly and arranged in a similar manner to service cables on other racks. |
Cable labeling |
Labels are clearly marked and securely attached. |
Empty slot |
Empty slots are covered with filler panels for proper heat dissipation and a neat appearance. |
Power cable plug |
One end of each power cable is fully plugged into an external power socket and the other end into a storage device socket. |
Signal cable plug |
Signal cables are fully plugged into appropriate device ports. |
Ground cable |
One end of each ground cable is secured by a ground clip and the other end is fastened to a rack ground terminal. |
Power cable |
Two groups of power cables are available for redundancy. |
Front-end port connection |
|
Management network port connection |
One end of each management network cable is fully plugged into a storage device management network port and the other end is connected to the network where the maintenance terminal resides. |
Procedure
- Verify that power cables (with strong electrical current) and service cables (with weak electrical current) lay on different sides of a rack.
- Verify that power cables and service cables are laid out orderly and arranged in a similar manner to cables on other racks.
- Verify that labels are clearly marked and securely attached.
- Verify that vacant slots are covered with filler panels.
- Verify that one end of each power cable is fully plugged into an external power socket and the other end into a storage device socket.
- Verify that signal cables are fully plugged into appropriate device ports.
- Verify that one end of each ground cable is secured by a ground clip and the other end is fastened to a rack ground terminal.
- Verify that two groups of power cables are available for redundancy.
- Verify that one end of each network cable or optical fiber is fully plugged into a storage device's front-end port and the other end into an application server port or a switch port.
- Verify that one end of each management network cable is fully plugged into a storage device management network port and the other end is connected to the network where the maintenance terminal resides.
Troubleshooting
If any check item fails to meet its standard, rectify the issue by referring to Table 4-2.
