摘要： Provided are a computer program product, system, and method to allocate blocks of memory in a memory device having a plurality of blocks. An unencrypted memory allocation function requests allocation of unencrypted blocks in the memory device. An encrypted memory allocation function requests allocation of encrypted blocks in the memory device. An unencrypted Input/Output (I/O) request performs an I/O operation against the unencrypted blocks in the memory device. An encrypted I/O request function performs an I/O operation against the encrypted blocks in the memory device. An operating system uses an encryption key associated with the encrypted blocks to encrypt or decrypt data in the encrypted blocks to perform the encrypted I/O operation in response to processing the encrypted I/O request functions, wherein the unencrypted and encrypted memory allocation functions and unencrypted and encrypted I/O request functions comprise different functions in a library of functions available to the application.

摘要： An apparatus, system, and method are disclosed for relocating logical array hot spots. An organization module organizes a plurality of logical arrays. Each logical array comprises a plurality of logical segments from a plurality of storage devices and configured to store data. An identification module identifies a hot spot on a first logical array if accesses to the first logical array exceed an access threshold. A migration module dynamically migrates a first logical segment from the first logical array to a second logical segment of a second logical array, wherein the migration is transparent to a host and data of the first logical segment is continuously available to the host.

摘要： An apparatus, system, and method are disclosed for relocating storage pool hot spots. An identification module identifies a hot spot on a first storage pool if accesses to the first storage pool exceed an access threshold. The first storage pool is part of a plurality of storage pools. Each storage pool comprises a plurality of logical segments from a plurality of storage devices. Each storage device is of a specified class. A migration module dynamically migrates data of a first logical segment to a second storage pool. The migration is transparent to a host and the data of the first logical segment is continuously available to the host.

摘要： An apparatus, system, and method are disclosed for migrating wear spots in solid-state drives. A count module counts lifetime write cycles for logical units of a plurality of solid-state memories. Each logical unit has a logical address. An identification module identifies a wear spot on a first logical unit of a first solid-state memory if a count for the first logical unit exceeds a cycle threshold. A migration module dynamically migrates data of the first logical unit to a second solid-state memory, wherein the data is continuously available at an original logical address.

摘要： A secondary storage controller receives metadata that uniquely identifies a source volume of a primary storage controller. Data stored in the source volume of the primary storage controller is synchronously copied to a target volume of the secondary storage controller. The secondary storage controller receives a command from a primary host to write selected data to the source volume. In response to receiving the command at the secondary storage controller, the selected data is written to the target volume of the secondary storage controller.
