Abstract: Systems and methods are provided for providing a consistent experience for users of cloud-based block storage volumes. While cloud storage aims to remove hardware considerations for an end user's experience, block storage performance can nevertheless vary according to the underlying hardware used to support a volume or the specific network location of that hardware. Embodiments of the present disclosure address that inconsistent performance by associating a volume with a performance profile that sets a target latency for the volume. A storage client can then monitor observed latency for the volume and inject synthetic latency into input/output operations for the volume as calculated via a proportional-integral-derivative algorithm, such that the observed latency matches the target within the performance profile. This enables the cloud provider to vary physical hardware or network configurations without effect on block storage performance from the point of view of an end user.

Abstract: A magazine-based data storage library in connection with a disk drive-based archive storage system is described that essentially generates parity data for tape formatted data streams (stored to tape cartridges) that do not align by way of data blocks or file marks. Data streams intended for tape storage sent to tape cartridges are also sent to a disk drive storage system via an encoder where parity of the data streams can be generated. More specifically, the encoder digitally formats tape blocks and tape marks (as well as other tape formatted structure) in a digital stream of data that can be added to other encoded digital streams of data to generate parity. To reconstruct a specific tape cartridge from a tape set, the encoded data from each of the tapes in the tape set are subtracted from the parity data and the remaining encoded data is decoded and sent to a designated tape cartridge.

Abstract: This disclosure provides a memory controller for asymmetric non-volatile memory, such as flash memory, and related host and memory system architectures. The memory controller is configured to automatically generate and transmit redundancy information to a destination, e.g., a host or another memory drive, to provide for cross-drive redundancy. This redundancy information can be error (EC) information, which is linearly combined with similar information from other drives to create “superparity.” If EC information is lost for one drive, it can be rebuilt by retrieving the superparity, retrieving or newly generating EC information for uncompromised drives, and linearly combining these values. In one embodiment, multiple error correction schemes are use, including a first intra-drive scheme to permit recovery of up to x structure-based failures, and the just-described redundancy scheme, to provide enhanced security for greater than x structure-based failures.

Abstract: SCSI commands that are not supported by a client terminal can be enabled. In scenarios where the client terminal's operating system may not support the same SCSI commands as the server's operating system, a redirected mass storage device that does support the same SCSI commands as the server's operating system can still be initialized on the server as supporting these SCSI commands. Then, to allow the SCSI commands that are not supported by the client terminal's operating system to be provided to the mass storage device, a client-side proxy can employ a SCSI Pass Through Interface to send the unsupported commands rather than providing them to the client-side disk driver. The proxy may still provide supported SCSI commands to the client-side disk driver for typical handling.
