    Elastic Compute Service:Instance families with high clock speeds (hf series)

    Last Updated:Nov 21, 2024

    Instance families with high clock speeds (hf series) provide CPU-to-memory ratios of 1:2, 1:4, and 1:8 and are suitable for scenarios such as massively multiplayer online (MMO) games, high-performance scientific computing scenarios such as high-performance computing, and large and medium-sized database systems.

    Background information

    Before you read further in this topic, you must be familiar with the following information:

    • Classification and naming of instance types. Familiarize yourself with the instance family categories, naming conventions of instance types, and differences between instance families. For more information, see Classification and naming of instance types.

    • Instance type metrics. For information about the metrics of instance types, see Instance type metrics.

    • Instructions for selecting instance types based on your business scenarios. For more information, see Instance type selection.

    After you determine an instance type for your use case, you may need to learn about the following information:

    • Regions in which the instance type is available for purchase. Instance types that are available for purchase vary based on the region. You can go to the Instance Types Available for Each Region page to view the instance types available for purchase in each region.

    • Estimated instance costs. You can calculate the price of instances that uses different billing methods in the Price Calculator.

    • Instructions for purchasing an instance. You can go to the ECS instance buy page to place a purchase order for instances.

    You may be concerned about the following information:

    • Retired instance families. If you cannot find an instance type in this topic, the instance type may be in a retired instance family. For information about retired instance families, see Retired instance families.

    • Supported instance type changes. Before you change the instance type of an instance, check whether the instance type can be changed and identify compatible instance types. For more information, see Instance types and families that support instance type changes.

        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

      • Scenarios where large volumes of packets are received and transmitted, such as live commenting on videos and telecom data forwarding

      • Enterprise-level applications of various types and sizes

      • Websites and application servers

      • Game servers

      • Small and medium-sized database systems, caches, and search clusters

      • Data analytics and computing

      • Computing clusters and memory-intensive data processing

    • Compute:

      • Offers a CPU-to-memory ratio of 1:4.

      • 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 ESSDs, ESSD AutoPL disks, standard SSDs, and ultra disks.

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

        Note

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

    • Network:

      • Supports IPv4 and IPv6.

      • Provides ultra-high packet forwarding rates.

      • Provides high network performance based on large computing capacity.

    The hfg6 instance family includes the following instance types: ecs.hfg6.large, ecs.hfg6.xlarge, ecs.hfg6.2xlarge, ecs.hfg6.3xlarge, ecs.hfg6.4xlarge, ecs.hfg6.6xlarge, ecs.hfg6.8xlarge, ecs.hfg6.10xlarge, ecs.hfg6.16xlarge, and ecs.hfg6.20xlarge.
