Abstract: A remote copy relationship is maintained between a local computational device and a remote computational device for a first storage volume and a second storage volume. The local computational device transmits information to the remote computational device, wherein the information indicates that there are no deduplication matches between the first storage volume and the second storage volume in the local computational device, and wherein the remote computational device is configured to avoid scanning for deduplication matches between a remote copy of the first storage volume and a remote copy of the second storage volume based on the information that is transmitted.

Abstract: A method, system, computer program product and computer program for managing a storage system, comprising a primary system and a backup system, wherein the backup system is in a copy relationship with the primary system, comprising: in response to a write operation, the write operation comprising first data: calculating a cryptographic value for the first data; scanning a first directory to identify an entry corresponding to the cryptographic value to determine a first set of addresses associated with the write operation; transmitting the first set of addresses to the backup system; and updating the first directory with a first entry for the write operation, the first entry comprising a pointer to the first set of addresses; updating a second directory with a second entry for the write operation, the second entry comprising a pointer to a second set of addresses corresponding to the first set of addresses.

Abstract: Provided are a computer program product, system, and method for using energy considerations to determine preferred and non-preferred paths to redundant first and second storage systems having a volume. A determination is made whether a first value of an energy attribute for the first storage system satisfies an energy criteria and whether a second value of the energy attribute for the second storage system satisfies the energy criteria. First paths to the first storage system are indicated as preferred and second paths to the second storage system are indicated as non-preferred in response to determining that the first value satisfies the energy criteria and the second value does not satisfy the energy criteria. The first paths are indicated as non-preferred and the second paths are indicated as preferred in response to determining that the first value does not satisfy the energy criteria and the second value satisfies the energy criteria.

Abstract: A method for attesting use of an interactive component during a boot process, comprising the steps of: reading, in response to determining use of the interactive component, associated interactive input; determining whether the input should be trusted; and in response to determining that the input should be trusted, processing the input to create a trusted cryptographic value, further comprising: matching, in response to a subsequent interactive input being read, the subsequent interactive input with one or more of the trusted cryptographic values in order to determine whether the subsequent interactive input is trusted.
