Storage Plug-ins
The following options are available:
- S3 Storage Plugin
A storage solution based on the Amazon S3 cloud service. In this situation, Rosetta can be connected to the cloud and the Permanent repository is located on Amazon servers.
![rcStrgPlgnS3.png](https://knowledge.exlibrisgroup.com/@api/deki/files/158003/rcStrgPlgnS3.png?revision=1)
S3StoragePlugin
With this storage plug-in, the following parameters are used:
- Endpoint – the URL of the entry point of the AWS Web service
- Bucket name – This is the term used by Amazon for describing the location of the files in their cloud.
- Secret Access Key – The access key for the bucket.
- Access Key ID – The key ID.
- Maximum waiting time – The time Rosetta will wait for response from Amazon when retrieving files. When the time elapses, Rosetta displays a message to the user that the file is not accessible.
- NFS Pair Tree Storage Plug-in
An NFS plug-in in which the directory structure inside the file system is based on the files’ fixity value and not dates.
![rcStrgPlgnNFSPairTree.png](https://knowledge.exlibrisgroup.com/@api/deki/files/158004/rcStrgPlgnNFSPairTree.png?revision=1)
NFSPairTreeStoragePlug-in
In the pair tree storage, files are located in a folder that is created based on an MD5 hash of their PID. This increases the speed and efficiency when search algorithms are used to retrieve files.
- NFS Storage Plugin
The original out-of-the-box plug-in provided by Rosetta. Files are stored conventionally, based on their date of upload.

NFSStoragePlugin
Parameters for the NFS storage plug-in are described below.
Storage Parameters for NFS Storage
Field | Description |
---|---|
Storage Parameter Name | The name of the storage parameter. |
Root Directory |
The root directory of the storage. e:\storage1\data\2008\06\10. |
Directory Prefix |
The directory prefix that is part of the directory name. For example, if the directory prefix is file$, the system creates the following directories:
|
Files Per Directory | The maximum number of files that can be saved in the storage. When the maximum number of files that can be saved in the directory is reached, the system creates a new directory. |
Storage Max Size (MB) | The total amount of data that can be saved in the storage. |
Storage Block Size |
The storage block size is used for an exact calculation of the available disk space. It is strongly recommended that you leave this field at its default value.
|
Files Handling Method |
Select one method from the three available:
|
- Net App Storage Plugin
The NetApp plug-in is a storage solution by NetApp, Inc., that integrates with the Rosetta storage system.
![rcStrgPlgnNetApp.png](https://knowledge.exlibrisgroup.com/@api/deki/files/158006/rcStrgPlgnNetApp.png?revision=1)
NetApp Plug-in
The NetApp application manages the storage of files in a combination of tapes and disks. Rosetta interacts only with the management layer, which stores and retrieves files for Rosetta.
- Google Storage
The Google plug-in is a storage solution by Google, that integrates with the Rosetta storage system.
