Abstract: The embodiments herein generate parity check data which serves as parity-on-parity. Stated differently, the parity check data can be used to determine if parity data stored in a memory element has been corrupted. For example, after generating the parity data, a computing system may set the parity check data depending on whether there is an even or odd number of logical ones (or logical zeros) in the parity data. Thus, when the parity data is read out of the memory element, if the parity data does not include the same number of even or odd bits, the parity check data indicates to the computing system that the parity data is corrupted. In one embodiment, to reduce the likelihood that the parity check data becomes corrupted, the computing system stores this data in hardened latches which are less susceptible to soft errors than other types of memory elements.

Abstract: The present disclosure describes methods and apparatus for implementing a signature-based sleep recovery operation flow for booting a system-on-chip (SoC). When the SoC begins its normal boot flow, a controller retrieves a sleep recovery signature from a register and compares the retrieved sleep recovery signature to a default signature. If the sleep recovery signature matches the default signature, the SoC enters a ROM checksum fail debug flow and, upon satisfying the requirements of the ROM checksum fail debug flow, enters a sleep recovery boot flow, which restores the SoC to the operational state it was in prior to entering the sleep mode. If the sleep recovery signature does not match the default signature, the SoC continues with the normal boot flow or, by use of external pins, can be forced into a normal debug mode flow so that the boot code can be debugged.

In response to receiving a request to provision a virtual database corresponding to a point in time, a recovery milestone is identified and transaction logs applied to the recovery milestone to create a database snapshot corresponding to the requested point in time.

Abstract: Techniques are described for reducing I/O operations and storage capacity requirements for centralized backup storage systems. A central server optimizes the collection and centralization of backup data from a number of endpoint devices for backup purposes. The central server utilizes a single instance store and a persistent files cache to minimize the number of backup copies for each non-unique file, reduce storage usage, network traffic, memory footprint and CPU cycles required to identify and process non-unique data. For each file in the single instance store, the server tracks the source device of that file until a threshold number of devices have been reached. Once the file reaches the threshold number of sources, the file is marked as persistent and its hash value is placed in the persistent files cache. Thereafter, all pointer creation and reference counting for that file cease.

Abstract: A method and an information handling system (IHS) provide hierarchical failure recovery for firmware components of the information handling system. According to one aspect, a hierarchical recovery and learning module (HRLM) detects firmware component failure. The HRLM initiates a hierarchical failure recovery by executing recovery sequences from a set of hierarchically ordered recovery sequences. The HRLM determines whether the detected failure was corrected by executing the recovery sequence. If the HRLM further determines that the failure is not corrected by executing the set of hierarchically ordered recovery sequences, the HRLM dynamically generates a new recovery sequence(s) using commands selected from at least one of the previously executed recovery sequences and executes the new recovery sequence(s). If the failure is corrected by a new recovery sequence, the HRLM forwards the particular recovery sequence to a customer support site for use by other systems in addressing similar or identical failures.
