Techniques for providing increased support for deduplication and compression of encrypted storage volumes. The techniques include receiving, at a storage virtual machine (VM), a data encryption key (DEK) associated with encrypted volume data, in which the DEK is wrapped in a key encryption key (KEK). The techniques include receiving, at the storage VM from a client virtual machine (VM), a write request specifying the encrypted volume data. The techniques include obtaining, by the storage VM, the KEK from a key management system (KMS) embedded on the storage VM. The techniques include unwrapping, by the storage VM, the DEK using the KEK, and decrypting, by an IO decryptor hosted by the storage VM, the encrypted volume data using the DEK. The techniques include performing, by the storage VM, data reduction operations on the decrypted volume data, and storing, by the storage VM, the data-reduced volume data on a storage array.

Systems and methods of supporting deduplication and compression of encrypted storage volumes

A virtual storage appliance having multiple storage processors is installed in a virtualized execution environment. Each one of the multiple virtual storage processors is a virtual machine that executes in the virtualized execution environment. At the time the virtual storage appliance is installed, properties of virtual resources provided by the virtualized execution environment to the virtual storage processors are obtained. The virtual resources provided by the virtualized execution environment to the virtual storage processors are consumed by the virtual storage processors while processing Input/Output (I/O) requests that are received by the virtual storage processors from at least one consumer application. The virtual storage processors are automatically configured in response to the properties of the virtual resources provided by the virtualized execution environment that are obtained at the time the virtual storage appliance is installed.

Automatic configuration of multiple virtual storage processors

A method, computer program product, and computing system for receiving content on a high-availability storage system. The content is compared to one or more entries in a static database associated with a cache memory system of the high-availability storage system. If the content does not match the one or more entries in the static database, the content is compared to one or more entries in a dynamic database associated with the cache memory system. If the content does not match the one or more entries in the dynamic database: the content is written to the cache memory system and a representation of the content is written to a temporal database associated with the cache memory system and maintained for a defined period of time.

Pattern detection system and method

Described are licensing techniques that may include: receiving a license specifying a maximum limit of a resource where the maximum limit denotes a maximum allowable consumption amount of the resource; providing the maximum limit to one or more software components; and enforcing, by the one or more software components, consumption of the maximum limit of the resource whereby an actual amount of the resource consumed is not allowed to exceed the maximum limit. The maximum limit may be a maximum storage capacity limit in connection with a virtualized storage system or appliance as well as a non-virtualized storage system or appliance. Software components may enforce the maximum limit, or a dependent limit derived therefrom, on the control path and data path. Limits specified in the license, or a dependent limit determined therefrom, may denote a maximum or minimum limit.
