Instance Specifications (Kunpeng Compute)

Kunpeng-based FlexusX instances provide stable compute and high-performance networks based on Huawei-developed Kunpeng processors. They can meet enterprises' requirements for high cost-effectiveness, security, and reliability. The following table lists the features of FlexusX instances powered by Kunpeng compute.

Compute	Disk Type	Network
vCPU/Memory ratio: flexible custom ratios to meet your specific needs with low-cost resources vCPU/Memory range: 2 to 80 vCPUs and 1 to 320 GiB of memory Processor: Kunpeng 920 new model Basic frequency: 2.9 GHz	High I/O General Purpose SSD Ultra-high I/O Extreme SSD General Purpose SSD V2	Ultra-high PPS throughput An instance with higher specifications has better network performance. Maximum PPS: 10,000,000 Maximum network bandwidth: 60 Gbit/s

Kunpeng instance specifications are only available in certain regions. The vCPU and memory specifications of FlexusX instances vary slightly in different regions. For details, see the specifications displayed on the console.

FlexusX instances may use different CPU models. To prevent services from being affected by inconsistent processor names in the OS, the processors are named General Purpose Processor.

The instance specifications determine the network bandwidth and packets per second (PPS).

Assured Network Bandwidth: indicates the initial bandwidth configuration of a FlexusX instance. It indicates the maximum transmission bandwidth that can be reached under normal network conditions.
Max. Network Bandwidth: indicates the maximum transmission bandwidth that can be reached by a FlexusX instance when the host network bandwidth is idle. No SLA is committed.
- All the instance specifications are verified in the forwarding-only test environment. In actual service scenarios, the instance performance may vary due to factors such as the instance load type, packet length, persistent and non-persistent connections, image version, and networking model. You are advised to perform a stress test to learn about the instance performance first and select appropriate instance specifications.
- The maximum bandwidth is the total bandwidth allocated to a FlexusX instance. If an instance has multiple NICs, the sum of the maximum bandwidths allocated to all NICs cannot exceed the maximum bandwidth allocated to the FlexusX instance.
Max. Network PPS: The maximum number of packets that the FlexusX instance can transmit and receive per second. The unit is PPS, which means the number of packets sent and received per second.
- All the instance specifications are verified in the forwarding-only test environment. In actual service scenarios, the instance performance may vary due to factors such as the instance load type, packet length, persistent and non-persistent connections, image version, and networking model. You are advised to perform a stress test to learn about the instance performance first and select appropriate instance specifications.
- For details about how to test PPS, see How Can I Test the Network Performance?
Max. NIC Queues: allocates NIC interrupt requests to multiple vCPUs for higher PPS performance and bandwidth. For details about how to enable NIC multi-queue, see Enabling NIC Multi-Queue.
Max. NICs: the maximum number of NICs that can be attached to a FlexusX instance. An NIC is an elastic network interface. For details, see Elastic Network Interface.
Max. Supplementary NICs: the maximum number of supplementary NICs that can be attached to a FlexusX instance. A supplementary NIC is a supplement to NICs. If the number of NICs that can be attached to your instance cannot meet your requirements, you can use supplementary NICs. For details, see Supplementary Network Interface.
