ECS Flavor Naming Rules

ECS flavors are named using the format "AB.C.D".

The format is defined as follows:

  • A specifies the ECS type. For example, s indicates a general ECS, c a computing ECS, and m a memory-optimized ECS.
  • B specifies the type ID. For example, the 1 in s1 indicates a general first-generation ECS, and the 2 in s2 indicates a general second-generation ECS.
  • C specifies the flavor size, such as medium, large, or xlarge.
  • D specifies the ratio of memory to vCPUs expressed in a digit. For example, value 4 indicates that the ratio of memory to vCPUs is 4.

Network Bandwidth

The intranet bandwidth and PPS of an ECS are determined based on ECS flavors.
  • Assured intranet bandwidth: indicates the assured ECS bandwidth.
  • Maximum intranet bandwidth: indicates the maximum ECS bandwidth.
  • Maximum intranet PPS: indicates the maximum ECS capabilities in transmitting and receiving packets.
