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.

• General computing (S2)

• General computing (S3)

• General computing-plus (C3)

• General computing-plus (C4)

• Disk-intensive (D2)

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.
