Elastic Compute Service:Instance types with high clock speeds

Last Updated:Jun 20, 2024

This topic describes the features of instance families with high clock speeds and lists the instance types of each instance family.

hfc7, compute-optimized instance family with high clock speeds

Features:

  • This instance family offloads a large number of virtualization features to dedicated hardware with the use of the third-generation SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.

  • Compute:

    • Offers a CPU-to-memory ratio of 1:2.

    • Uses Intel® Xeon® Cooper Lake processors that deliver an all-core turbo frequency of 3.8 GHz and have a minimum clock speed of 3.3 GHz to provide consistent computing performance.

    • Allows you to enable or disable Hyper-Threading.

      Note

      By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.

  • Storage:

    • Is an instance family in which all instances are I/O optimized.

    • Supports only ESSDs and ESSD AutoPL disks.

    • Provides high storage I/O performance based on large computing capacity.

      Note

      For more information about the storage I/O performance of the next-generation enterprise-level instance families, see Storage I/O performance.

  • Network:

    • Supports IPv6.

    • Provides ultra-high packet forwarding rates.

    • Provides high network performance based on large computing capacity.

  • Supported scenarios:

    • Scenarios in which large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding

    • High-performance frontend server clusters

    • Frontend servers of massively multiplayer online (MMO) games

    • Data analytics, batch processing, and video encoding

    • High-performance scientific and engineering applications

hfc6, compute-optimized instance family with high clock speeds

Features:

  • This instance family offloads a large number of virtualization features to dedicated hardware with the use of SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.

  • Compute:

    • Offers a CPU-to-memory ratio of 1:2.

    • Uses 3.1 GHz Intel® Xeon® Platinum 8269CY (Cascade Lake) processors that deliver a turbo frequency of 3.5 GHz to provide consistent computing performance.

      Note

      The processors used by this instance family have a clock speed of 3.1 GHz. However, the Intel System Studio (ISS) feature may cause a lower clock speed to be displayed. Alibaba Cloud is working on this issue. This issue does not affect the actual clock speeds of your instances.

      You can separately run the following commands to use the turbostat tool to view the actual clock speeds:

      yum install kernel-tools
      turbostat
    • Allows you to enable or disable Hyper-Threading.

      Note

      By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.

  • Storage:

    • Is an instance family in which all instances are I/O optimized.

    • Supports Enterprise SSDs (ESSDs), ESSD AutoPL disks, standard SSDs, and ultra disks.

    • Provides high storage I/O performance based on large computing capacity.

      Note

      For more information about the storage I/O performance of the next-generation enterprise-level instance families, see Storage I/O performance.
