A method of operating a storage device may include determining a fault condition of the storage device, selecting a fault resilient mode based on the fault condition of the storage device, and operating the storage device in the selected fault resilient mode. The selected fault resilient mode may include one of a power cycle mode, a reformat mode, a reduced capacity read-only mode, a reduced capacity mode, a reduced performance mode, a read-only mode, a partial read-only mode, a temporary read-only mode, a temporary partial read-only mode, or a vulnerable mode. The storage device may be configured to perform a namespace capacity management command received from the host. The namespace capacity management command may include a resize subcommand and/or a zero-size namespace subcommand. The storage device may report the selected fault resilient mode to a host.

An integrated circuit. The circuit includes a communication module including shared ports, and an error management module for managing at least one case of an error. The circuit is configured to communicate on multiple internal communication channels via the ports. The error management module includes at least one hardware path for selectively switching off the individual communication channels in the case of an error.

A system and method for managing a reduction in capacity of a memory sub-system. An example method involving a memory sub-system: configuring the memory device with a zoned namespace comprising a plurality of zones; notifying a host system of a failure associated with a zone of the plurality of zones, wherein the failure affects stored data; receiving from the host system an indication to continue at a capacity that is reduced; recovering the stored data of the zone affected by the failure; and updating the set of memory devices to change the capacity to a reduced capacity.

Systems and techniques for transparent dynamic reassembly of computing resource compositions are described herein. An indication may be obtained of an error state of a component of a computing system. An offload command may be transmitted to component management software of the computing system. An indication may be received that workloads to be executed using the component have been suspended. An administrative mode command may be transmitted to the component. The administrative mode command may place the component in partial shutdown to prevent the component from receiving non-administrative workloads. Data of the component may be synchronized with a backup component. Workloads from the component may be transferred to the backup component. An offload release command may be transmitted to the software of the computing system.

A method includes reserving memory capacity in a first memory device as patch memory region for backing faulted memory, receiving a memory error indication indicating an uncorrectable error in a faulted segment in a second memory device and, in response to the memory error indication, associating in a remapping table the faulted segment with a patch segment in the patch memory region. The faulted segment is smaller than a memory page size of the second memory device. The method also includes, in response to receiving a memory access request directed to the faulted memory segment, servicing the memory access request from the patch segment by querying the remapping table to determine a patch segment address corresponding to a requested memory address, where the patch segment address identifies the location of the patch segment, and based on the patch segment address, performing the requested memory access at the patch segment.

A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a fault state from which partial recovery is possible by operating the storage device in a first read-only mode; and operating the storage device in the first read-only mode, the operating in the first read-only mode including: determining that the age of a first data item stored in a page of the storage device has exceeded a threshold age, and copying the first data item into a rescue space in the storage device.

A storage system, and a method for operating a storage system. In some embodiments, the system includes a first storage device and a second storage device, and the method includes: determining that the first storage device is in a read-only state and that the second storage device is in a read-write state; performing a write operation, of a first stripe, to the storage system; performing a first read operation, of a second stripe, from the storage system; and performing a second read operation, of the first stripe, from the storage system, wherein: the performing of the write operation includes: writing a portion of the first stripe to the second storage device, and making an entry in a mapping table for the first stripe.

A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a first fault state from which recovery is possible by power cycling the storage device or by formatting the storage media; determining, by the storage device, that the storage device is in a second fault state from which partial recovery is possible by operating the storage device with reduced performance, with reduced capacity, or in a read-only mode; and operating the storage device with reduced performance, with reduced capacity, or in the read-only mode.

Disclosed is a method, apparatus, and system for dynamically changing a backup policy, the operations comprising: automatically detecting a change in a backup source system; automatically activating a new backup policy, wherein the new backup policy is determined based on the change in the backup source system and an old backup policy; and performing a backup session based on the new backup policy.
