Abstract: Deletion of data stored via a geographically diverse storage is disclosed. In response to determining that a first chunk and a second chunk of a first zone are to be deleted, a portion of the first and second chunks can be received at a second zone comprising a third and fourth chunk. The third chunk can comprise data represented by the first chunk and the fourth chunk can comprise data represented by the second chunk. The portion of the first and second chunks, and the third and the fourth chunks can be employed in generating a fifth chunk that comprises data from the third and fourth chunks other than data represented in the first and second chunks. In an aspect the portion of the first and second chunks can be received via a sixth chunk generated at the first zone.

Abstract: A computer of a data processing system includes a software encryption engine and path circuitry that initially provides one or more paths for conveying data of storage I/O requests to and from a storage device, the paths including an encrypting path having a hardware encrypting component. According to a failover technique, in a first operating state, (a) the data of the storage I/O requests is conveyed via the encrypting path with encryption and decryption of the data being performed by the hardware encrypting component, and (b) monitoring is performed for occurrence of an event indicating that the hardware encrypting component has become unavailable for encrypting and decrypting the data of the storage I/O requests.
