Abstract: Many error correction schemes fail to correct for double-bit errors and a module must be replaced when these double-bit errors occur repeatedly at the same address. This helps prevent data corruption. In an embodiment, the addresses for one of the memory devices exhibiting a single-bit error (but not the other also exhibiting a single bit error) is transformed before the internal memory arrays are accessed. This has the effect of moving one of the error prone memory cells to a different external (to the module) address such that there is only one error prone bit that is accessed by the previously double-bit error prone address. Thus, a double-bit error at the original address is remapped into two correctable single-bit errors that are at different addresses.

Abstract: Methods, systems, and apparatus, including computer-readable storage media for uncorrectable memory recovery. Different sources of uncorrectable memory error are handled to provide for recovery actions by a host kernel of a machine hosting one or more virtual machines. Rather than defaulting to kernel panic behavior, the host kernel can identify the source of uncorrectable error, and cause the host machine and/or the affected virtual machines to take recovery action that is less disruptive than abrupt shutdown from panic. For example, the host kernel can handle uncorrectable memory error caused by kernel accesses to guest memory of a host virtual machine, as well as uncorrectable memory error improperly raised as a result of known defects in host machine hardware. The host kernel can also be configured to detect sources of overflow in exceptions raised by a processor as a result of uncorrectable memory error.

Abstract: While booting a host computing device on a cloud computing system, system firmware (such as Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI)) sends a query to a management subsystem (such as a baseboard management controller (BMC)) for updated configuration data used during a boot of the host computing device. The management subsystem sends the updated configuration data to the system firmware, and boot instructions in the system firmware compare the updated configuration data with configuration data stored on the host computing device. If the respective configuration data match, the boot instructions continue with booting the host computing device. If the configuration data do not match, then the boot instructions update the stored configuration data with the updated configuration data and then proceed to boot the host computing device.

Abstract: A disaster-recovery system contains a networked array of synchronous-to-asynchronous converter (SATC) modules that connect source databases to target backup databases. During backup, the system replicates each source-database transaction through a chain of these SATCs to a corresponding target, storing a local copy of the transaction on each SATC along the way. Each transaction's path between its source-target pair is identified by a set of tracking entries, where each entry identifies one SATC in the path. Every backup transfer between two SATCs in a chain is performed synchronously, such that a successor SATC confirms a successful transfer to a predecessor SATC only after the successor can confirm a successful transfer to the next SATC in the chain. During a subsequent recovery operation, tracking entries are regenerated to locate locally stored transactions that had not time to be fully replicated before a catastrophic failure had occurred.
