Examples described herein relate to a Transport Layer Security (TLS) offload engine to: based on detection of encrypted data unassociated with a previously detected data header: search for one or more data headers; identify at least two candidate data headers for validation; and based on receipt of an indication that the at least two candidate data headers are valid, perform decryption of received data in one or more packets. In some examples, the TLS offload engine is to: based on receipt of an indication that one or more of the at least two candidate data headers is not a valid header, search for two or more other candidate data headers.

Offload of decryption operations

When rebuilding a RAID (Redundant Array of Independent Disks) array in which a drive has failed, if another RAID array contains a mirror copy of the of the rebuilding RAID array content, this mirroring RAID array can be used to more rapidly rebuild the RAID array with the failed drive. Data requests to the rebuilding RAID array can be redirected to the mirroring RAID array; data can be transferred from the mirroring RAID array; or a combination of these can be used to finish rebuilding more quickly. When transferring data to the rebuilding array from the mirroring array, the transfer can be performed as a direct memory access (DMA) process independently of the RAID module of either array.

RAID array rebuild assist from external array copy

Example storage systems and methods provide multichannel communication among subsystems, including a compute complex. A plurality of storage devices, a host, and a compute complex are interconnected over an interconnect fabric. The storage system is configured with a host-storage channel for communication between the host and the plurality of storage devices, host-compute channel for communication between the host and the compute complex, and a compute-storage channel for communication between the compute complex and the storage devices.
