Abstract: A database-aware storage server provides instant creation of snapshots without the need to create an intermediate test master database. During the snapshot creation time, the source database stays read-write and completes ongoing reads and writes. The database-aware storage server allows creation of layers of writable snapshots in a hierarchy. All these multiple databases share common data blocks. Any new writes performed by the database post snapshot are stored in blocks of sparse files. This promotes space sharing and reduces the total amount of space used by all these related databases. The allocations for the source and all new snapshot databases share the same common pool of storage. The newly created snapshot databases can access the data store directly without going through an intermediate layer.

Abstract: Techniques are provided for using an intermediate cache between the shared cache of an application and the non-volatile storage of a storage system. The application may be any type of application that uses a storage system to persistently store data. The intermediate cache may be local to the machine upon which the application is executing, or may be implemented within the storage system. In one embodiment where the application is a database server, the database system includes both a DB server-side intermediate cache, and a storage-side intermediate cache. The caching policies used to populate the intermediate cache are intelligent, taking into account factors that may include which object an item belongs to, the item type of the item, a characteristic of the item, or the type of operation in which the item is involved.

Abstract: Techniques are provided for using an intermediate cache to provide some of the items involved in a scan operation, while other items involved in the scan operation are provided from primary storage. Techniques are also provided for determining whether to service an I/O request for an item with a copy of the item that resides in the intermediate cache based on factors such as a) an identity of the user for whom the I/O request was submitted, b) an identity of a service that submitted the I/O request, c) an indication of a consumer group to which the I/O request maps, or d) whether the intermediate cache is overloaded. Techniques are also provided for determining whether to store items in an intermediate cache in response to the items being retrieved, based on logical characteristics associated with the requests that retrieve the items.
