This topic describes the specifications for ApsaraDB for MongoDB standalone instances.
Notes
The memory specified for an instance type is shared by MongoDB management services, database services, and the underlying operating system. This includes memory reserved for the BIOS, kernel, and hypervisor. Therefore, the available memory is less than the memory specified for the instance type.
For more information about the maximum input/output operations per second (IOPS) and throughput of different disk types, see Enterprise SSDs (ESSDs).
General-purpose instances with cloud disks do not support disk encryption.
To use standalone instances that run MongoDB 4.2 or later, submit a ticket.
A single collection file cannot exceed 16 TB. Otherwise, the instance becomes unavailable.
