High-Performance Computing ECSs

Overview

H1 (high-performance computing first-generation) ECSs provide a large number of CPU cores, large memory size, and high throughput. These ECSs are suitable for high-performance processor applications restricted by computing performance.

The processor and memory ratio of an HC2 (high-performance computing second-generation) ECS is 1:2 or 1:4. Each vCPU corresponds to the hyperthreading of an Intel Xeon processor core. HC2 ECSs are applicable to high-performance computing services. They provide a large number of parallel computing resources and high-performance infrastructure services to meet the requirements of high-performance computing and massive storage and ensure rendering efficiency. HC2 ECSs are frequently used in the following scenarios:

  • Computing and storage systems for genetic engineering, games, animations, biopharmaceuticals, and scientific computing
  • Public rendering platforms for renderfarms and animation and film bases; other rendering platforms for movies and videos
  • High-performance frontend clusters, web servers, high-performance science and engineering applications, advertisements, video coding, and distributed analysis
NOTE:

H1 ECSs have been discontinued. HC2 ECSs that feature higher performance are available for new orders and capacity expansion for H1 ECSs.

Notes on Using H1 ECSs

  • H1 ECSs do not support NIC hot swapping.
  • H1 ECSs support modifying specifications only if the source and target ECSs are of the same type.
  • H1 ECSs support the following OSs:
    • CentOS 6.8 64bit
    • CentOS 7.2 64bit
    • CentOS 7.3 64bit
    • Windows Server 2008
    • Windows Server 2012
    • Windows Server 2016
    • SUSE Enterprise Linux Server 11 SP3 64bit
    • SUSE Enterprise Linux Server 11 SP4 64bit
    • SUSE Enterprise Linux Server 12 SP1 64bit
    • SUSE Enterprise Linux Server 12 SP2 64bit
    • Red Hat Enterprise Linux 6.8 64bit
    • Red Hat Enterprise Linux 7.3 64bit
  • The primary and extended NICs of an H1 ECS have specified application scenarios. For details, see Table 3.
    Table 3 Application scenarios of the primary and extended NICs of an H1 ECS

    NIC Type

    Application Scenario

    Remarks

    Primary NIC

    Applies to vertical layer 3 communication.

    N/A

    Extended NIC

    Applies to horizontal layer 2 communication.

    To improve network performance, you can set the MTU of the extended NIC to 8888.
