Dynamic communications paths for sensors in an autonomous vehicle, comprising: detecting a fault associated with a first sensor of a plurality of sensors associated with a same sensing space of the autonomous vehicle; severing, in response to detecting the fault, a first communications path in a switched fabric between a processing unit and the first sensor; and establishing, via the switched fabric, in response to detecting the fault, a second communications path between the processing unit and a second sensor of the plurality of sensors.

Switch topology-aware path selection in an information processing system is provided. For example, an apparatus comprises a host device comprising a processor coupled to a memory. The host device is configured to communicate with a storage system over a network with a plurality of switches. The host device is further configured to obtain topology information associated with the plurality of switches in the network, and select a path from the host device to the storage system through one or more of the plurality of switches based at least in part on the obtained topology information.

Embodiments of the present disclosure relate to a memory system, a memory controller, and a method of operating the memory system. According to the embodiments of the present disclosure, when result data obtained by derandomizing data included in a flag area is different from reference data after a random data unit is derandomized based on a seed, it is possible to detect an error occurring in the seed in a process of derandomizing the data and to prevent malfunction of firmware in advance by searching for a target seed and derandomizing the random data unit based on the target seed.

One or more techniques and/or systems are provided for cluster configuration information replication, managing cluster-wide service agents, and/or for cluster-wide outage detection. In an example of cluster configuration information replication, a replication workflow corresponding to a storage operation implemented for a storage object (e.g., renaming of a volume) of a first cluster may be transferred to a second storage cluster for selectively implementation. In an example of managing cluster-wide service agents, cluster-wide service agents are deployed to nodes of a cluster storage environment, where a master agent actively processes cluster service calls and standby agents passively wait for reassignment as a failover master in the event the master agent fails. In an example of cluster-wide outage detection, a cluster-wide outage may be determined for a cluster storage environment based upon a number of inaccessible nodes satisfying a cluster outage detection metric.

A redundant sensor fabric in an autonomous vehicle may include receiving, by a processing unit, sensor data from a first sensor of a plurality of sensors associated with a same sensing space of the autonomous vehicle; detecting a fault associated with the first sensor; establishing, via a switched fabric, a communications path between the processing unit and a second sensor of the plurality of sensors; and receiving, by the processing unit, sensor data from the second sensor instead of the first sensor.

A server computer can have multiple potential configurations depending on a state of an input signal. In a first potential configuration, a single-platform model is used with multiple processors booted using a single BIOS. The multiple processors can have a bus there between allowing processor-to-processor communication. In a second potential configuration, a multi-platform model is used with multiple processors booted using separate BIOS. In this configuration, the bus between the processors is disabled so that the platforms operate autonomously. The hardware can be extended to support additional processors, such as 4, 8, etc. A failover mode also allows the hardware to detect a hardware error (e.g., bus error) and dynamically reconfigure the processors to use an alternative bus. With the failover, the addressing of the processors can be modified to reconfigure the server computer to compensate for the hardware error.

System and method for managing distributed storage objects for host unavailability in a distributed storage system uses at least one of a crash indicator in a specific on-disk block and a paused object indicator for a distributed storage object to determine whether to perform data recovery for the distributed storage object. When the crash indicator is set or the paused object indicator implies that the distributed storage object is a paused object, the distributed storage object is left as a paused object without perform the data recovery for the distributed storage object. When the crash indicator is unset and the paused object indicator implies that the distributed storage object is not a paused object, the data recovery for the distributed storage object is performed.

A computer-implemented method for memory macro disablement in a cache memory includes identifying a defective portion of a memory macro of a cache memory bank. The method includes iteratively testing each line of the memory macro, the testing including attempting at least one write operation at each line of the memory macro. The method further includes determining that an error occurred during the testing. The method further includes, in response to determining the memory macro as being defective, disabling write operations for a portion of the cache memory bank that includes the memory macro by generating a logical mask that includes at least bits comprising a compartment bit, and read address bits.

According to some embodiments, a backup storage system receives a request from a client to access a data segment. The system looks up an in-memory index for a first entry based on a fingerprint of the data segment, such that the in-memory index includes a number of entries, each entry mapping a fingerprint to a storage location of a solid state device (SSD) storing a corresponding data segment. In the event a first entry is found, the system retrieves the data segment from the SSD device based on the first entry. In the event of a read failure while accessing the SSD device, the system determines failed data blocks of the SSD device associated with the failure event and invalidates the failed data blocks of the SSD device such that subsequent access to the failed data blocks are denied without having to access a corresponding SSD device.

Provided are a storage system and a storage control method wherein, when communication is disabled (communication via a data communication path is disabled) in spite of replacement of a second CTL among a first CTL and the second CTL that are redundant storage controllers and that are coupled via the data communication path, the first CTL executes a write process of writing dirty data and data management information to one or more storage devices while maintaining acceptance of I/O requests from a host. The replaced second CTL reads the data management information from the one or more storage devices. The first CTL stops accepting I/O requests from the host. The replaced second CTL starts accepting I/O requests from the host.
