ECS Specifications Used by MRS¶

MRS uses ECSs of the following types in different application scenarios.

Note

The ECS specifications available on MRS console vary by cluster version.

ECS Flavor Naming Rules¶

AB.C.D

Example: m3.8xlarge.8

In the preceding flavor:

A specifies the ECS type. For example, s indicates a general-purpose 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-purpose first-generation ECS, and the 2 in s2 indicates a general-purpose second-generation ECS.
C specifies a flavor size and can be any of the following options: medium, large, and 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.
