CloudBox is a fully managed cloud service provided by Alibaba Cloud. The hardware infrastructure of the cloud boxes that you purchase is deployed in your data center and delivered in racks. Before you deploy the purchased cloud boxes in your data center, Alibaba Cloud engineers make an appointment with you to perform an on-site engineering survey on your data center and accordingly determine whether the data center meets the deployment requirements. This topic describes the requirements that must be met to deploy cloud boxes in a data center.
Environment requirements
Item | Requirement |
Rack |
Important Alibaba Cloud provides maintenance services for servers and network devices in a rack. You cannot move or operate the devices in a cloud box unless you are authorized by Alibaba Cloud to do so. |
Temperature and humidity |
Important If the monitored temperature of the data center in which the cloud boxes are deployed exceeds 40°C for four consecutive hours and Alibaba Cloud cannot contact your data center contact, Alibaba Cloud has the right to temporarily disable your cloud boxes to prevent unexpected disasters that are caused by further temperature increases in the data center. |
Weight | The bearing capacity of the installation foundation in the specified geographical location must be greater than the maximum weight of the hardware infrastructure in the order that you place. |
Altitude | The altitude of your data center can be at most 1,500 m. |
Lightning protection | The lightning protection and grounding systems of your data center must follow the regulations in GB 50689-2011 Code for Design of Lightning Protection and Earthing Engineering for Telecommunication Bureaus (Stations). |
Seismic design | The seismic design category of the buildings of your data center must be located at least Category C. |
Electrostatic discharge | The absolute value of the electrostatic voltage to earth of the floor, workbench, communications equipment, and operators in your data center must be at least 200 V. The installation of the electrostatic discharge (ESD) floor must meet the technical requirements specified in SJ/T 10796-2001 General Specification for Raised Access Floors for Electrostatic Protection. The surface resistance and system resistance of the ESD floor must range from 1 × 10^5 Ω to 1 × 10^9 Ω. |
Electromagnet | The strength of the radio interference field in the data center and the auxiliary area cannot exceed 130 dB (µV/m) at frequencies from 80 MHz to 1,000 MHz and from 1,400 MHz to 2,000 MHz. The strength of the power-frequency magnetic field cannot exceed 30 A/m. |
Network requirements
Cloud boxes can be connected to the Alibaba Cloud public cloud over Express Connect circuits. Only dedicated Express Connect circuits are supported. For more information, see Connect to Alibaba Cloud through a dedicated Express Connect circuit.
The following section describes the deployment requirements that must be met if you use the connection over an Express Connect circuit.
Upstream switches
One or two upstream switches with physical interfaces at 10 Gbit/s must be provided in each cloud box. We recommend that you use two upstream switches in each cloud box.
The upstream switches must support Border Gateway Protocol (BGP), Layer 3 subinterfaces, and IEEE 802.1Q.
External Border Gateway Protocol (EBGP), virtual local area networks (VLANs), and subinterfaces must be supported for the connections between the upstream switches and cloud boxes. The virtual routing and forwarding (VRF) feature is optional for the connections.
The cloud connection channel and the Express Connect circuit must support physical interfaces at 10 Gbit/s. Each upstream switch must provide at least two physical interfaces for one rack or four physical interfaces for multiple racks to connect to the one or more cloud boxes. The number of
/30CIDR blocks required varies based on the number of physical interfaces.NoteThe cloud connection channel provides a network connection between the cloud boxes and the Alibaba Cloud public cloud. The channel carries the traffic for cloud box management and migration to Alibaba Cloud. The Express Connect circuit provides a network connection between the cloud boxes and your on-premises devices.
Configurations
The rack of each cloud box contains two top-of-rack (ToR) switches. The business traffic that passes through each ToR switch is routed to the upstream switches. Four connection links are provided for each data processing business. The following table describes the configuration requirements.

Network bandwidth
To ensure a better user experience, we recommend that you allocate a minimum network bandwidth of 50 Mbit/s for cloud boxes. This ensures that Elastic Compute Service (ECS) instances and cloud disks can be created when the cloud boxes are connected to the Alibaba Cloud public cloud. A bandwidth of more than 50 Mbit/s is required if the number of racks in your data center is large and the cloud boxes need to communicate with virtual private clouds (VPCs) in the Alibaba Cloud public cloud.
Power supply requirements
Each rack supports the 10 kW and 20 kW power supplies. The power supply configuration of a cloud box depends on the total power consumption of different types of compute stock keeping units (SKUs) that you purchase for the cloud box. For example, if the maximum power consumption of the purchased compute SKUs is at most 10 kW, you can use the 10 kW power supply. You can obtain information about the maximum power consumption of different types of compute SKUs in your order.
Power | Input voltage and frequency | Current | Number of primary and secondary power distribution units (configured at a ratio of 1:1) |
10 kW | Single-phase 220 V, 50 Hz or 60 Hz | 63 A | 1 + 1 |
20 kW | Single-phase 220 V, 50 Hz or 60 Hz | 63 A | 2 + 2 |
Delivery requirements
After you place an order online, Alibaba Cloud engineers make an appointment with you on specific dates to perform an on-site engineering survey on your data center and deliver the cloud boxes that you purchase. After the cloud boxes are delivered, you must verify and confirm the completion of the order at the earliest opportunity. After the completion of the order is confirmed, the billing cycle of the cloud boxes starts.
Phase | Requirement |
On-site engineering survey | You must appoint network engineers and electrical engineers to cooperate with Alibaba Cloud engineers to complete the engineering survey. A physical report on the results of the engineering survey is provided by Alibaba Cloud. You can renovate your data center based on the suggestions in the report as needed. |
