Notes on Using D1 ECSs

  • Do not support NIC hot swapping.
  • The primary and extension NICs of a D1 ECS are used in scenarios shown in Table 9.
    Table 9 Application scenarios of the NICs of a D1 ECS

    NIC Type

    Scenarios

    Remarks

    Primary NIC

    Vertical layer 3 communication

    -

    Extension NIC

    Horizontal layer 2 communication

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

  • D1 ECSs do not support specifications modification.
  • D1 ECSs do not support OS reinstallation or change.
  • D1 ECSs support the following OSs:
    • CentOS 7.2 64bit
    • CentOS 7.3 64bit
    • CentOS 6.8 64bit
    • 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
  • D1 ECSs can use both local disks and EVS disks to store data. Note the following when using these two types of disks to store data:
    • Only an EVS disk can be used as the system disk of a D1 ECS.
    • Both EVS disks and local disks can be used as data disks of a D1 ECS.
    • A D1 ECS can be attached with up to 60 disks (including local disks). For details about constraints, see Can I Attach Multiple Disks to an ECS?
      NOTE:

      The maximum number of disks attached to an existing D1 ECS remains unchanged.

  • The basic resources, including vCPUs, memory, and image of a stopped D1 ECS are still billed. To stop the ECS from being billed, delete it and its associated resources.

Notes on Using H1 ECSs

  • Do not support NIC hot swapping.
  • Support specifications modification only if the source and target ECSs are of the same type.
  • 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 extension NICs of an H1 ECS have specified application scenarios. For details, see Table 11.
    Table 11 Application scenarios of the NICs of an H1 ECS
