Abstract: A system and method for recognizing data access patterns in large data sets and for preloading a cache based on the recognized patterns is provided. In some embodiments, the method includes receiving a data transaction directed to an address space and recording the data transaction in a first set of counters and in a second set of counters. The first set of counters divides the address space into address ranges of a first size, whereas the second set of counters divides the address space into address ranges of a second size that is different from the first size. One of a storage device or a cache thereof is selected to service the data transaction based on the first set of counters, and data is preloaded into the cache based on the second set of counters.

Abstract: One or more techniques and/or systems are provided for performing host side deduplication. Host side deduplication may be performed upon writeable data within a write request received at a host computing device configured to access data stored by a storage server. The host side deduplication may be performed at the host computing device to determine whether the writeable data is already stored by the storage server based upon querying a host side cache comprising data stored by a storage server and/or a data structure comprising unique signatures of data stored by the storage server. If the writeable data is stored by the storage server, then a deduplication notification excluding the writeable data may be sent to the storage server, otherwise a write command comprising the writeable data may be sent. Accordingly, unnecessary network traffic of redundant data already stored by the storage server may be reduced.

Abstract: A hardware and/or software facility to enable emulated storage devices to share data stored on physical storage resources of a storage system. The facility may be implemented on a virtual tape library (VTL) system configured to back up data sets that have a high level of redundancy on multiple virtual tapes. The facility organizes all or a portion of the physical storage resources according to a common store data layout. By enabling emulated storage devices to share data stored on physical storage resources, the facility enables deduplication across the emulated storage devices irrespective of the emulated storage device to which the data is or was originally written, thereby eliminating duplicate data on the physical storage resources and improving the storage consumption of the emulated storage devices on the physical storage resources.

Abstract: A clustered storage environment can distribute responsibility for naming virtual disks to nodes of the clustered storage environment. The clustered storage environment maintains a list of names in a structure that is visible to cluster member nodes responsible for naming the virtual disks. As the cluster member nodes discover mass storage devices (e.g., storage arrays) in the clustered storage environment, the nodes determine identifiers of the mass storage devices. For each mass storage device, the nodes use the mass storage device identifier to establish a namespace for virtual disks of the corresponding mass storage device. The nodes can then provide consistent, exclusive names for the virtual disks throughout the cluster that are manageable names.

Abstract: Example embodiments provide various techniques for locating cryptographic keys stored in a cache. The cryptographic keys are temporarily stored in the cache until retrieved for use in a cryptographic operation. The cryptographic key may be located or found through reference to its cryptographic key identifier. In an example, a particular cryptographic key may be needed for a cryptographic operation. The cache is first searched to locate this cryptographic key. To locate the cryptographic key, the cryptographic key identifier that is associated with this cryptographic key is provided. In turn, the cryptographic key identifier may be used as an address into the cache. The address identifies a location of the cryptographic key within the cache. The cryptographic key may then be retrieved from the cache at the identified address and then used in the cryptographic operation.

Abstract: Described herein is a system and method for managing environment metadata of a server system during a backup session between the server system and a storage system. In some embodiments, during the backup session, the server system sends a sequence of blocks or files comprising backup data and environment metadata to the storage system. The backup data may comprise data on the server that is typically sent to the storage system during a backup session, such as client or application data. The environment metadata may include information describing the server system, such as information describing hardware or software components of the server system or server metrics of the server system. In these embodiments, operations for processing environment metadata may be included with the operations for processing backup data during the backup session.
