hfc6, compute optimized instance family with high clock speed

Features
  • Provides predictable and consistent high performance and reduces virtualization overheads with the use of the X-Dragon architecture.
  • I/O optimized.
  • Supports enhanced SSDs, standard SSDs, and ultra disks.
  • Provides strong 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.
  • Offers a CPU-to-memory ratio of 1:2.
  • Provides an ultra-high packet forwarding rate.
  • Equipped with 3.1 GHz Intel ® Xeon ® Platinum 8269 (Cascade Lake) processors with a maximum turbo frequency of 3.5 GHz.
    Note The CPU of this instance family provides a 3.1 GHz clock speed. The Intel System Studio (ISS) feature may cause a lower clock speed to be displayed. Alibaba Cloud is trying to fix the display problem. The problem does not affect the actual clock speed of your instances.
    You can run the following commands separately to use the turbostat tool to view actual CPU frequencies.
    yum install kernel-tools
    turbostat
  • 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.
