Abstract: The present disclosure relates to systems, methods, and computer readable media for identifying and responding to a panic condition on a storage system on a computing node. For example, systems disclosed herein may include establishing recovery instructions between a host system and a storage system in responding to a future instance of a panic condition. The storage system may provide an indication of a self-detected panic condition in a variety of ways. In response to identifying the panic condition, the host system may perform one or more recovery actions in accordance with recovery instructions accessible to the host system. This may include performing resets of specific components and reinitializing communication between the host system and storage system in less invasive ways than slower and more expensive conventional approaches for responding to panic conditions on computing nodes.

Abstract: Data from a host system is received at a memory device, where the memory device includes a primary region to initially store the data received from the host system and one or more secondary regions to store data transferred from the primary region. A write operation is performed on one or more write units of the primary region with the data received from the host system, where a write unit of the primary region has lower density blocks than a write unit of the secondary region. Whether a subset of write units of the primary region corresponding to a pre-determined number of write units is written with at least a portion of the data received from the host system is determined. In response to determining that the subset of write units of the primary region is written, another write operation is performed on at least one write units of the secondary region with respective data of the subset of write units of the primary region.

Abstract: A processing device receives a command from to execute a read operation. The processing device determines a memory component of media where the read operation will be executed using an address included with the read operation. The processing device determines that there is a read lock on the memory component. The processing device determines that a count of read operations dependent on the read lock has reached a read threshold. Based on this determination, the processing device adds the read operation to a read lock queue. The processing device executes a write operation prior to the read operation as a consequence of adding the read operation to the read lock queue.

Abstract: A data storage device is disclosed comprising a non-volatile memory comprising a plurality of sectors. A partition map is evaluated that identifies a partition accessed through a plurality of logical block addresses (LBAs), where each LBA maps to a fraction of a sector. A partition offset is determined for the partition relative to a boundary of one of the sectors. N write commands are received each having a write offset relative to a corresponding sector. When the write offset for X of the N write commands matches the partition offset, at least part of the partition is moved to align at least part of the partition to a boundary of one of the sectors.

A plurality of write commands received from a host are stored in the command queue, and write data for the write commands is stored in the VSM. A flush time needed to flush the write data from the VSM to the disk is computed, and the write data is flushed from the VSM to a non-volatile memory (NVM) in response to the flush time.
