To enable an Equinox client to use multimedia attachments, Presence Services requires an attachment store. Presence Services uses different attachment stores for the following deployment methods:
On-premise: Presence Services attachment store uses the on-cluster virtual hard disk space that is provided by the virtual host services through its datastores. You can also build the datastores from local hard disks or SAN disk arrays.
Cloud: Presence Services uses AWS S3 storage as the attachment store, along with a local caching store.
The maximum size of a multimedia attachment file is 32 MB. You can configure the default size settings for different attachment types such as video, audio, image, and text in the Presence Services service attributes. When you exceed the attachment store limit, Presence Services automatically starts removing the oldest attachment files from the store.
