Commvault supports direct connection to ECS using the Atmos, S3, Swift, or CAS REST APIs. Security for each of these APIs must first be configured for the appropriate ECS user before they can be used within Commvault. The implementation sections that follow review best practices for configuring a single storage library using each of the supported APIs to be shared with the MediaAgents, the CommCell policy configurations, and the necessary alerts for virtual deployments.
The ECS Object Services communicate on different ports depending on the protocol and data access API, as follows:
Data access method | HTTP | HTTPS |
S3 | 9020 | 9021 |
Atmos | 9022 | 9023 |
Swift | 9024 | 9025 |
ECS requires a storage pool, virtual data center, replication group, namespace, and an object user with an S3 and Swift password, an Atmos sub-tenant and CAS password, bucket, and pea file depending on the API being used.
Note: This document focuses on the two most popular protocols, namely S3 and CAS.
