Moreover, the method further includes in response to determining that the cache is in a busy status, allocating to the cache at least one additional flash block from a second file system in the storage, the second file system being different from the first file system.

Configuring docks

In some examples, an electronic device is to receive a configuration setting that is configurable to a first setting to indicate a first mode of operation, and a second setting to indicate a second mode of operation, wherein a feature supported by the first mode of operation is disabled in the second mode of operation; and configure a dock to which the electronic device is connected to operate according to a mode indicated by the configuration setting.

SELECTING A DISCONNECT FROM DIFFERENT TYPES OF CHANNEL DISCONNECTS BY TRAINING A MACHINE LEARNING MODULE

Provided are techniques for selecting a disconnect by training a machine learning module. A machine learning module is provided that receives inputs and produces an output. The output produced from the machine learning module based on the inputs for the first I/O operation and an estimated amount of time to acquire resources for a first I/O operation is determined. An actual amount of time to acquire resources for the first I/O operation is determined. The machine learning module is retrained based on the inputs, the output, and the actual amount of time it took to acquire resources for the first I/O operation versus an estimated amount of time to acquire the resources for the first I/O operation. The retrained machine learning module is used to select one of disconnect from a channel, the logical disconnect from the channel, or the physical disconnect from the channel for a second I/O operation.

SYSTEMS AND METHODS FOR SAFELY DETECTING INDETERMINATE STATES OF RANGES IN A SELF-ENCRYPTING STORAGE RESOURCE

An information handling system may include a host system processor and a storage resource communicatively coupled to the host system processor. The storage resource may be configured to, responsive to receiving a command from the host system processor relating an address range of the storage resource, create an entry in a drive status table stored in a persistent storage area of the storage resource, the entry setting forth information indicative of the address and a completion status of the command and update a status of the address range in the drive status table as steps of the command are completed by the storage resource, such that, if a drive event occurs preventing full completion of the command, the host system processor may access the drive status table to determine a status of the command, and take a remedial action based on the status of the command.

Latency optimized I3C virtual GPIO with configurable operating mode and device skip

Systems, methods, and apparatus for communicating virtual GPIO information generated at multiple source devices and directed to multiple destination devices. A method performed at a device coupled to a serial bus includes generating first virtual GPIO state information representative of state of one or more physical GPIO output pins, asserting a request to transmit the first virtual GPIO state information by driving a data line of the serial bus from a first state to a second state after a start code has been transmitted on a serial bus and before a first clock pulse is transmitted on a clock line of the serial bus, transmitting the first virtual GPIO state information as a first set of bits in a data frame associated with the start code, and receiving second virtual GPIO state information in a second set of bits in the data frame.
