Below are a few comparisons between Object Storage devices and media (namespaces) as compared to other Storage Manager media:
- An Object Storage media belongs to no policy class as the default. That is, multiple classes can have data on the same media (this matches sdisk).
- Multiple stores can be occurring to the same media simultaneously. The number of streams to a device is configurable (this matches sdisk).
- A copy number is assigned to each Object Storage media when it is
configured. When files are stored, only copies of the indicated number
go to a specific media.
- This copy number can be changed by an administrator when the media is blank.
- By definition, if files have multiple copies stored to Object Storage media, then an Object Storage media (namespace) per copy number must be configured.
- If there are multiple media configured for the same copy number, then at store time the media with the most available space is selected for use.
- If a set of media become full, new ones are configured and assigned whatever copy numbers are needed or desired. This is assuming there is another set of storage nodes with space available.
