  • Supports enhanced SSDs (ESSDs).
  • Provides high network and storage I/O performance based on large computing capacity.
    Note For more information about the storage I/O performance of the new generation of enterprise-level instance families, see Storage I/O performance.
  • Provides an ultra high packet forwarding rate.
    Note The maximum network performance varies with instance families. For more concurrent connections, we recommend that you use g5ne. For more information, see the "g5ne, general purpose instance family with enhanced network performance" section in Instance families.
  • Offers a CPU-to-memory ratio of 1:4.
  • Equipped with 2.5 GHz Intel ® Xeon ® Platinum 8269 (Cascade) processors with a maximum turbo frequency of 3.2 GHz.
  • Allows you to enable or disable Hyper-Threading.
    Note By default, Hyper-Threading is enabled on ECS instances. For more information, see Customize CPU options.
  • Suitable for the following scenarios:
    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
    • Enterprise-level applications of various types and sizes
    • Websites and application servers
    • Game servers

Note
  • You can go to the ECS Instance Types Available for Each Region page to view the instance types available in each region.
  • For more information about these specifications, see Instance specifications.
  • The results for network capabilities are obtained from single item tests. For example, when network bandwidth is tested, no stress tests are performed on the packet forwarding rate or other metrics of the network.
