Deployment Requirements

Evaluate whether your location is suitable for deploying an edge site based on the following tables.

If your location fails to meet the requirements, you can register an edge site and place an order on the console, and then contact the Huawei Cloud technical support for a solution.

Equipment Room

**Table 1** Equipment room environment
Category	Requirement
Temperature	The ambient temperature ranges from 5°C to 35°C when the altitude of the equipment room is from –60 m to 1800 m. The ambient temperature is reduced by 0.45°C per 100 meters when the altitude of the equipment room ranges from 1800 m to 3000 m.
Humidity	The ambient relative humidity range of 20 to 80 percent is optimal for server reliability and operator comfort, and no condensing is allowed.
Rack layout	Racks are at least 1 m away from walls or any obstacles.
Firefighting equipment	Gas fire extinguishers are provided in the equipment room where the racks are deployed.
Water resistance	Racks should not be installed near toilets, kitchens, or wet areas.
Soot	Racks should not be installed near smoke sources or powder layers.

**Table 2** Electric and electrical power
Category	Requirement
Power supply availability	≥ 99.982% (no more than 1.6 hours of downtime per year)
24/7 power supply	Edge sites should always be on if there is power supply in the equipment room. Do not power off edge sites daily or periodically.
Mains supply	Dual-channel mains power
Rack power supply	Power of each channel: ≥ 6 kW Current of each channel: ≥ 32 A Air circuit breakers connected to racks: 220 V power supply, 1 pole, ≥ 32 A current Power supply: 220 V AC, 230 V AC, or 240 V AC, 1 PH
Industrial connector	Each cable tray at the rear of racks must be equipped with industrial female connectors. It is recommended that the cable tray is installed at the top of racks. If the cable tray is installed on the bottom of racks, record the information for subsequent evaluation. Industrial connector specifications: IP44 connectors (2P+E) that comply with IEC60309 requirements must be used. Female connectors must be installed in the equipment room, and male connectors (with 3 x 6 mm² cables) must be installed on racks. Connectors can be used for devices with 32 A/220 V power supply.
UPS	2N redundancy is required for UPSs. UPSs can provide power supply for at least 15 minutes.
Ground cable of racks	There must be ground copper bars at the rear (top or bottom) of racks, and two screw holes must be reserved for each rack. Ground bars cannot exceed 30 m and must be securely connected to the ground grid in the equipment room. You can use galvanized flat steel with a cross-sectional area of 40 x 4 mm² or larger or a cable with a cross-sectional area of 95 mm² or larger. The flat steel or cable must be insulated, corrosion-proof, and free of any damaged points, and its exposed part must be protected against mechanical damage. The equipment room must use joint grounding. The working ground and the protection ground must share the same ground with the lightning-proof ground. The ground resistance must be less than 10 Ω or meet the requirements of local standards. Each rack has a proper ground point and equipotential grounding is used between racks.

Rack Space

**Table 3** Rack installation
Category	Requirement
Cabling	Overhead cabling is recommended. The distance between the cable tray or fiber trough and the top of racks should be less than or equal to 1 m. If the distance is greater than 1 m, record the detailed cabling length.
Floor load bearing	The bearing capacity of the floor is greater than 1,000 kg/m².
Power	The minimum power for a single rack is 6,000 W.
Installation position	The installation position must be able to accommodate a rack with the dimensions of 2000 mm x 600 mm x 1200 mm (H x W x D). The cold aisle must be 1.2 m or larger in width, and the hot aisle must be 0.6 m or larger in width.
Expandable space	Sufficient space should be reserved if capacity expansion is required later.
Cabling between the edge site and on-premises network devices	Check whether there is a cable trough on the top of racks and whether multi-mode optical fiber can be used for cabling between racks and on-premises network devices. Record the cabling length.

Rack Transportation

**Table 4** Rack unloading
Category	Requirement
Unloading area	The unloading area meets height and ramp requirements for an 8-ton freight carrier truck. The working space must be of sufficient width, depth, and height to allow unloading of racks. The depth must be greater than 6.5 m.
Unloading route	Any platforms, hallway, elevators, doorways, turns, and ramps from the delivery site to the final resting position must have sufficient clearance. The road surface for trucks passes must be level (roughness: ±3 cm). There are no thresholds or steps along the route from the unpacking room to the rack installation position. There is no height difference along the route. If the ground is not level, the incline must be less than 8 degrees.
Freight elevator	If racks are transported with packaging, the freight elevator door must be at least 2.4 m high and 1.5 m wide. If racks are transported without packaging, the freight elevator door must be at least 2 m high. The clearance between the car-platform sill and the hoistway edge of any landing sill must be less than 20 mm. The load-bearing capacity of the freight elevator must be greater than or equal to 2 tons. There must be at least two freight elevators in the equipment room.

On-Premises Network

Learning about the networking requirements can help you quickly understand the requirements for on-premises networks.

**Table 5** Requirements for on-premises networks
Category	Requirement
Brand and model of network switches	The brand and model of network switches connected to racks can be selected as needed.
Number of switches	One or two switches (If there is only one switch, evaluate the risk of high availability. If there are two racks, stack the switches.)
Optical modules on switches	Multi-mode or single-mode optical modules must be used. Electrical ports are not supported.
Rate and number of optical ports on switches	Optical port rate: 100 Gbit/s (recommended), 40 Gbit/s, 25 Gbit/s, or 10 Gbit/s Number of ports: 2, 4 (recommended), 8, or 14 (The number of ports varies according to the rate of the optical port.)
Public IP address	Four public IP addresses are required for connecting the edge site to the cloud (IP addresses (2), (3), and (4) described in Table 3) (2) indicates two public IP addresses and (4) indicates one public IP address you purchase from a carrier, and (3) indicates one IP address you purchase on the EIP console.
Public network egress	At least 200 Mbit/s is required (for management IP addresses and interconnection IP addresses). If you use other connections, ensure that they meet the requirements for network communications between edge sites and the cloud. To avoid network quality problems, do not share the existing public network egress with CloudPond. If these IP addresses need to be shared, ensure that there are no network conflicts.
Public IP address availability	Public IP addresses must be 24/7 available. The network interruption cannot exceed 24 hours.
Network latency	The network latency between the edge site and the cloud must be less than or equal to 150 ms.
