    Abstract: Techniques are provided for performing automated operations to enable first-failure data capture functionality during initialization of multiple lockstep processors. Following a hardware reset of two lockstep processors, an indication is received of one or more crosscheck errors regarding the operation of the two lockstep processors. In response to the crosscheck errors, crosscheck first-failure data capture (FFDC) data is saved to one or more memory areas that are persistent across a hardware reset, and it is determined whether a predefined reset threshold has been satisfied. Responsive to determining that the predefined reset threshold has been satisfied, the crosscheck FFDC data from the one or more persistent memory areas is analyzed and one or more crosscheck initialization codes are responsively generated. An additional hardware reset is initiated.

    Abstract: Technologies for virtual multipath access include a computing device configured to sequester a recovery partition from a host partition while allowing the recovery partition to access one or more resources of the host partition such as host memory or data storage. A remote computing device determines whether the host partition is responsive. The recovery partition receives a request for host state data of the host partition from the remote computing device in response to a determination that the host partition is not responsive. The recovery partition retrieves the requested host state data using a host state index maintained by the host partition and transmits the requested host state data to the remote computing device. The host state index may identify the location of the requested host state data. The remote computing device may perform a recovery operation based on the received host state data. Other embodiments are described and claimed.

    Abstract: A memory system includes: a non-volatile memory device that includes a plurality of memory blocks each of which includes a plurality of pages; and a controller suitable for programming write data together with corresponding write order information in the plurality of the pages during a write operation, wherein when two or more open blocks are detected among the plurality of the memory blocks during a recovery operation, the controller generates an order table where physical page numbers of the pages of the open blocks are arrayed based on the write order information and determines at least one recovery target page among pages of the open blocks based on the order table.
