Abstract: A logical block address space of a storage compute device is reserved for use in executing commands from a host. First data is received at a first portion of the logical block address space, the first data causing a computation to be performed by the storage compute device. Second data is sent to the host via a second portion of the logical block address space, the second data describing a result of the computation.

Abstract: An apparatus comprises a laser diode configured to generate light during a write operation. A slider comprises a near-field transducer (NFT) and an optical waveguide. The slider is configured for heat-assisted magnetic recording and to communicate the light to the NFT via the waveguide. A writer heater of the slider is configured to receive power during the write operation. A thermal sensor is situated at or near an air bearing surface of the slider. The thermal sensor is configured to produce a sensor signal in response to sensing back-heating from the medium while the NFT generates heat during a write operation. Circuitry, coupled to the thermal sensor, is configured to compare the sensor signal to a threshold and generate an output signal indicative of degradation of NFT performance in response to the sensor signal exceeding the threshold.

Abstract: A key-value storage device and method of using the same. In some embodiments, keys are stored in a key store in a first non-volatile memory and corresponding values associated with the keys are stored in a value store of a second non-volatile memory. An input command is received from a host device, the input command having a key associated with a value. Different first and second hash values are generated by applying a hash function to the key. The input command is executed responsive to the first and second hash values.

Abstract: Commands associated with one or more logical block addresses are received via a host interface of a storage device. Based on a timing and sequence of the commands, an extent of a file that contains the logical block addresses is determined, the file being stored on the storage device. The logical block addresses are managed internally as a unitary data structure based on determining an association between the logical block addresses and the file.

A requirement of the data object is determined based on a computation to be performed on the data object. The requirement related to at least speed and capacity of media used to store the data object. A tier is selected from the storage compute device based on speed and capacity characteristics of the selected tier corresponding to the requirement of the data object. The data object is stored in the selected tier.
