Overview
In Container Mode, each container vault can store over 1 million containers. When enabled, I/O occurs at the container level instead of the container vault level. ACLs are enforced at the container level. Metrics are tracked at the container, storage account, and container vault levels. Containers and storage accounts are not visible on the Manager. Accesser® Devices can be used to create, update, and delete containers.
Container Mode supports the following APIs:
- Manager REST API for administration and monitoring
- APIs for service providers
- Cloud Object Storage API for end users to manage data I/O, containers, and objects
