HCP supports access to namespaces through a variety of industry-standard protocols. For actions such as adding objects to a namespace, viewing and retrieving objects, changing object metadata, and deleting objects, HCP supports:
- For HCP namespaces only:
- A RESTful HTTP API (simply referred to as HTTP in the HCP documentation).
- Hitachi API for Amazon S3, which is a RESTful, HTTP-based API that’s compatible with Amazon® S3. With this S3 compatible API, namespaces are called buckets.
- For the default namespace only, a non-RESTful implementation of HTTP.
- For all namespaces:
- WebDAV
- CIFS
- NFS
HCP allows special-purpose access to namespaces through two additional protocols: SMTP (for storing email) and, for the default namespace only, NDMP (for backing up and restoring data).
