Abstract: A storage controller for cache management that includes a cache memory and a cache management module. The cache management module to, on receipt of region specification requests from hosts, extract from the region specification requests cache rules for management of regions of data storage of a storage array, and on receipt of data operation requests from hosts, process the data operation requests based on the extracted cache rules.

Abstract: Example implementations relate to partitioning memory modules into volatile and non-volatile portions. For example, a system includes a memory controller to partition a memory module into a non-volatile portion and a volatile portion and to identify persistent data to be backed up during a power loss condition. The memory controller is further to transfer the persistent data from the volatile portion of the memory module to the non-volatile portion of the memory module, in response to the power loss condition.

Abstract: To migrate data from a first storage system to a second storage system, the second storage system detects a migration of a persistent storage media from the first storage system to the second storage system. In response to detecting the migration of the persistent storage media, write information from a write cache in the first storage system is copied to a write cache in the second storage system, where the write caches in the first and second storage systems were not maintained synchronously before the write information from the write cache in the first storage system is copied to the write cache in the second storage system.

Abstract: In a system, temperature measurements are logged. From the logged measurements, duration of operation of the system in each of a plurality of temperature bands is determined.

Abstract: Data read from a volume is decrypted using a first key. The decrypted data is encrypted using a second key. The encrypted data is written back to the volume. An access request to a location of the volume is received from a host. Data is encrypted to or decrypted from the location using the first or second key, in response to the access request. The first key is used for the access request if the location has not been decrypted using the first key and encrypted using the second key. The second key is used for the access request if the location has been decrypted using the first key and encrypted using the second key.

Abstract: Techniques that relate to wear-leveling cores of a multi-core processor are described in various implementations. The techniques may include determining, for a plurality of cores of a multi-core processor, usage information that is indicative of past wear on the plurality of cores. The techniques may also include selectively activating a subset of the plurality of cores based on the usage information such that cores that exhibit less wear relative to other cores are preferentially selected for activation.

Abstract: Data read from a volume is decrypted using a first key. The decrypted data is encrypted using a second key. The encrypted data is written back to the volume. An access request to a location of the volume is received from a host. Data is encrypted to or decrypted from the location using the first or second key, in response to the access request. The first key is used for the access request if the location has not been decrypted using the first key and encrypted using the second key. The second key is used for the access request if the location has been decrypted using the first key and encrypted using the second key.

Abstract: An authenticatable device includes a substrate and a computing device with encryption capability affixed to the substrate. The computing device is to receive a challenge value and a first value from a host device, generate a second value based on at least the first value, and generate a response value based on the challenge value and the second value.

Abstract: Embodiments include methods, apparatus, and systems for storage device data encryption. One method includes encrypting data on a storage device with a key and then transmitting the key to a cryptographic module that encrypts the key to form a Binary Large Object (BLOB). The BLOB is transmitted to an array controller that is coupled to the storage device which stores the BLOB.

Abstract: A method for loading a cache is disclosed. Data in a computer file is stored on a storage device. The computer file is associated with a computer program. The first step is to determine which logical memory blocks on the storage device correspond to the computer files (402). The next step is to take the data stored in the logical memory blocks and load it into a cache (404). The data is loaded into the cache before data from the file is requested by the computer programs.
