Checking the Installation Environment
Before installing the storage system, check the installation environment carefully. This helps ensure a successful installation and smooth running of devices.
Environmental Requirements
For correct and smooth installation of storage devices, ensure that the installation environment meets the requirements in Table 7-3.
In addition, make sure that the following special requirements are met:
- Ensure that doors, passageways, and elevators are of adequate dimensions to allow passage of the bays.
- Before installation, check whether to submit the qualification certificate of the installation company to the property management entity in charge of the installation site.
- Confirm the delivery time and installation time in advance, for example, from 8:00 a.m. to 6:00 p.m.
- Take particular care to avoid bumping into doors, walls, or shelves during transportation, relocation, or installation of storage devices.
- Do not touch the components or uncoated metal surface of any unit with dirty gloves.
For details about environment parameters such as the temperature, humidity, heat dissipation, vibration and shock, air quality, and system noise, see "Environmental Requirements" in the Product Description specific to your product model.
Fire Fighting Requirements
To secure an equipment room, ensure that the equipment room has a powerful fire fighting system.
A fire fighting system should be prepared by the customer. The customer must consult the insurance underwriter, local fire marshal, and building inspectors to select a fire fighting system of correct level of coverage and protection.
Because a fire fighting system must comply with local laws and regulations that vary with countries and regions, Huawei does not participate in the design and deployment of the customer's fire fighting system. Therefore, Huawei shares no responsibility for device damage and personal injuries caused by a fire fighting system failure.
Floor Load Capacity
The OceanStor storage system can be installed on both raised floors and non-raised floors. Before installing the OceanStor storage system, you must consult the specified agency to check that the OceanStor storage system and associated equipment do not place excessive weight on these floors or incur a structure risk for the building.
System Weight
Before installing the OceanStor storage system, consult the specified agency to ensure that the floor of an equipment room can support the storage system. To query the weights of fully loaded system bays, use Specifications Query (https://support-it.huawei.com/spec/#/home).
Load Capacity of a Raised Floor
For the OceanStor storage system, raised floors are preferable to non-raised floors.
To secure the load capacity of a raised floor, use the concrete-filled steely over-loading floor whose dimensions are 600 mm (W) x 600 mm (L) as the raised floor. If using another type of floor as the raised floor, ensure that the minimum rated load of the floor is not smaller than the device weight.
Customers must ensure that the floors in an equipment room provide sufficient strength to support the OceanStor storage system and associated equipment. Huawei shares no responsibility for personal injuries and device damage resulted from inadequate load capacity of these floors.
When deploying a bay on a raised floor, note the following:
- Horizontally align the floor.
- Ensure that the floor tiles and their vertical beams are able to bear the concentrated load of equipment room maintenance personnel and a bay's four wheels.
- Ensure that the minimum bearing strength of a floor tile is able to bear the concentrated load of equipment room maintenance personnel and a bay.
- Because floor tile cuts decrease the load capacity, place bases next to these cuts correctly after consulting the floor tile manufacturer.
- You can install iron or wooden plates on the ESD floor to reinforce it. The plates for protecting the floor are provided by carriers.
Power Requirements
Before installing the OceanStor storage system, ensure that the power supply system of an equipment room can support the storage system correctly working at maximum power consumption.
For the electronic specifications and power consumption of a single bay, see the "Electronic Specifications" in the Specifications Query (https://support-it.huawei.com/spec/#/home).
Power Supply Components of System Bays and Disk Bays
The OceanStor storage system supports AC power. All bays must use the same power supply standard.
AC and High Voltage DC Scenario
Each bay of the OceanStor storage system is equipped with two power distribution units (PDUs) on the two sides of the bay's rear end. This enables the OceanStor storage system to have dual power inputs. Table 3-16 lists the number of PDUs configured for different power supply modes.
Power Supply Mode |
Number of PDUs (System Bay) |
Number of PDUs (Disk Bay) |
|---|---|---|
Single-phase, 220 V, 32 A |
4 |
2 |
Three-phase, 380 V, 32 A |

High voltage DC, 240 V, 32 A |

Figure 3-40, Figure 3-41, and Figure 3-42 show appearances of different PDUs.
Power Supplies of Bays
Before installing the OceanStor storage system, survey the power supply system of an equipment room and determine a power supply solution for the bays. These operations ensure that the OceanStor storage system runs correctly after it is installed.
To ensure data security, each controller enclosure of the storage system is equipped with four backup battery units (BBUs). This allows data to be written to coffer disks if the storage system is unexpectedly powered off. In addition, the specifications of these power supplies must conform to the availability requirements specified in tier 2 or higher tier of the TIA942 (Standards of telecommunication infrastructure in data centers).
The AC power supplies of an equipment room must be deployed before the device installation. You can deploy the power supplies according to the availability requirements specified in tier 2 or higher tier of the TIA942. If possible, use one independent uninterruptible power supply (UPS) system and two independent power distribution frames (PDFs) to input power of each bay.
When the OceanStor storage system is being installed, Huawei technical support engineers and customers' electrical engineers must verify the redundancy of power supplies together.
Power Connectors
The OceanStor storage system supports AC power. Choose proper power connectors based on the site requirements.
AC and High Voltage DC Scenario
For areas where the European power supply standard is used, bays of the OceanStor storage system are equipped with AC power connectors that comply with IEC 60309. Figure 3-43 and Figure 3-44 show power connectors.
Power Supply Configuration
When connecting AC power supplies to the OceanStor storage system, note the following:
- Huawei technical support engineers discuss with customers about how to verify redundancy in bays' AC power supplies. If no redundant power supply exists, data may be unavailable or lost.
- Before connecting power supplies to the OceanStor storage system, customers must configure power supplies for the data center.
- The equipment room is equipped with a standby generator.
- In AC scenarios, each power distribution unit (PDU) in the bay is connected to an independent external power supply. In a scenario where four PDUs exist, four power supplies are required.
- At least one of the two power input lines is connected to an uninterruptible power supply (UPS).
- The power cables and connectors connected to the bays must be installed and deployed by professional personnel to ensure that the power system passes the tests and conforms to local electrical safety specifications.
- Customers' electrical engineers or facility representatives must verify that the voltages of the bays meet the voltage requirements of the OceanStor storage system.
Remote Support
Huawei customer service center can connect to the OceanStor storage system using the Internet or modem to remotely maintain the storage system.
After Huawei customer service center is remotely connected to the OceanStor storage system, it can inspect, operate, and maintain the storage system.
- Remote inspection
Huawei customer service center remotely connects to the OceanStor storage system or a maintenance terminal through the Internet and uses SmartKit (formerly named Toolkit, which is used as an example in this document) to perform a health check, ensuring the normal running of the storage system. To implement remote inspection, ensure that the management network of the equipment room can communicate with the Internet.
- Remote operation and maintenance
Huawei customer service center can remotely access the OceanStor storage system in public switched telephone network (PSTN) dialup mode to troubleshoot system faults. To implement remote operation and maintenance, ensure that the equipment room is accessible to the PSTN and equipped with a modem.
