ApsaraDB for MongoDB:Sharded cluster instance types

Last Updated:Jun 06, 2024

This topic describes the instance types of ApsaraDB for MongoDB sharded cluster 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.

Instances that use cloud disks

The following database engine versions are supported:

  • MongoDB 7.0

  • MongoDB 6.0

  • MongoDB 5.0

  • MongoDB 4.4

  • MongoDB 4.2

Note
  • For more information about how to select a storage capacity based on the IOPS, see Maximum IOPS for standard SSDs and ESSDs.

  • Shard nodes of the dedicated instance category that use cloud disks and adopt the following specifications can be deployed only in Singapore Zone A, Zone B, and Zone C: 64 CPU cores and 128 GB of memory, 64 CPU cores and 256 GB of memory, and 64 CPU cores and 512 GB of memory.

  • The storage capacity of a shard node is the storage capacity of each node. For example, if the storage capacity of a shard node is 20 GB, each primary or secondary node has a storage capacity of 20 GB.
