Table 1.1 List of Required Components
Component Name	Description
CSG Web GUI	GUI for setting and monitoring this product. Refer to "1.4.2 User Interface" for details.
Shared folders	NAS interfaces that are the gateways for cloud storage.
Cache	An area where data that has been written to a shared folder is stored temporarily before the data is transferred to a cloud storage. Cache is located on the local disk of the virtual machine. In addition to actual data, meta data (management data regarding deduplication and compression, and management data such as for cloud storage information of the data storage destination) is also stored. Actual data is written to cache after it is deduplicated and compressed. If there is room in the cache area, data that has been transferred to the cloud storage is kept in the cache in order to improve the response speed when data is read from shared folders.
Cloud provider	Refers to the cloud storage (such as Amazon S3) that is provided by cloud providers, and online storage environments for private clouds using OpenStack.
Bucket	Logical storage area that is created in a cloud storage.
Datastore	A cloud storage area where the data that is written to the shared folder is eventually stored. A datastore is created in a bucket in the cloud storage. In the same way as cache, actual data that has been deduplicated and compressed and meta data are stored in a datastore.
