Replica set instance types

This topic describes the available instance types of ApsaraDB for MongoDB replica set instances.

Note

  • The supported memory capacity includes the memory that is occupied by the management services in ApsaraDB for MongoDB, the database service, and the underlying operating system (such as the BIOS, the kernel of the operating system, and the hypervisor). Therefore, the available memory may be less than the memory capacity that is supported by the instance type.

  • Some instance types were upgraded on May 14, 2024. If the maximum number of connections to your instance is different from that described in this topic, you can restart the instance. For more information, see [Notice] Increase in the maximum connections to instances of specific specifications.

Instances that use cloud disks
Instances that use local disks

The following database engine versions are supported:

  • MongoDB 7.0

  • MongoDB 6.0

  • MongoDB 5.0

  • MongoDB 4.4

Note

For more information about the maximum IOPS and throughput of different disk types, see ESSDs and ESSD AutoPL disks.

Dedicated replica set instances that use cloud disks and adopt 64 CPU cores and 128 GB, 64 CPU cores and 256 GB, and 64 CPU cores and 512 GB specifications can be deployed only in Singapore Zone A, Zone B, and Zone C.

You can deploy general-purpose replica set instances that use cloud disks in the following regions and zones:

  • China (Hangzhou): Zone J.

  • China (Shanghai): Zone L and Zone N.

  • China (Beijing): Zone H and Zone K.

  • China (Shenzhen): Zone D.

  • China (Hong Kong): Zone B and Zone C.

  • Singapore: Zone A.

Note

  • If you select the multi-zone deployment mode when you create an instance, make sure that the selected instance type is supported in the specified zones.

  • Disk encryption is not supported by general-purpose replica set instances that use cloud disks.

The following database engine versions are supported:

  • MongoDB 4.2

  • MongoDB 4.0

  • MongoDB 3.4 (discontinued)
