Node Specifications

This section describes the node flavors supported by CCE and typical node features.

Node flavors vary depending on regions, and some flavors may be unavailable due to insufficient resources. To obtain available node flavors, log in to the CCE console and switch to the page for creating nodes.

In CCE Turbo clusters, pods need to occupy network interfaces or supplementary network interfaces of nodes. The number of pods you can create on a node depends on how many network interfaces that node has. You need to evaluate the number of network interfaces that can be attached to each node. For details, see Maximum Number of Pods That Can Be Created on a Node.

Node Type

Description

Flavors

ECS (VM)

ECS running on a KVM or QingTian hypervisor. Multiple flavors are offered to meet your compute and storage needs for various applications.

x86:

Arm (Kunpeng):

Heterogeneous:

ECS (PM)

ECS running on a QingTian-backed bare-metal hypervisor. PM resources and VM resources of such an ECS are in the same resource pool and can be dynamically scheduled.

General Computing-plus ECSs

BMS

BMS offering high-performance computing at low latency for containers.

Instance Family

General Computing-plus ECSs

General computing-plus ECSs use dedicated vCPUs and next-generation network acceleration engines to provide powerful compute and network performance.

General Computing-Basic ECSs

General computing-basic ECSs are suitable for scenarios that require moderate CPU performance generally but burstable high performance occasionally while keeping costs low. The performance of such ECSs is constrained by the baseline performance and CPU credits. There are no additional charges for using CPU credits. For details, see CPU Credits.

GPU-accelerated ECSs

GPU-accelerated ECSs provide outstanding floating-point computing capabilities. They are suitable for applications that require real-time, highly concurrent massive computing.

GPU-accelerated ECSs are classified as G series and P series ECSs.

  • G series: Graphics-accelerated ECSs, which are suitable for 3D animation rendering and CAD
  • P series: Computing-accelerated or inference-accelerated ECSs, which are suitable for deep learning, scientific computing, and CAE
