Abstract: A solid state drive (SSD) includes a nonvolatile memory array and a cache memory. The nonvolatile memory array has an encrypted integrated memory buffer (IMB) space. The cache memory has a decrypted copy of the IMB and an encrypted backup copy of the IMB. In power loss recovery (PLR) after a power loss imminent (PLI) event, the SSD can determine whether to recover the unencrypted copy of the IMB or the backup encrypted copy. The backup encrypted copy can reduce the risk of loss of data in the IMB in the event that multiple PLI events occur and a corrupted copy of the IMB is used to overwrite the IMB in the nonvolatile memory during a previous PLR.

Abstract: Technologies for storage discovery and reallocation include a compute device. The compute device is to receive, from a data storage sled, storage device data from a storage device located on the data storage sled. The storage device data includes storage device self-test data that defines a result of a self-test performed by the storage device. The compute device is also to determine, in response to the storage device self-test data, whether the storage device fails to satisfy a performance threshold. Further, the compute device is to generate, in response to a determination that the storage device fails to satisfy the performance threshold, an adjustment message for the storage device. The adjustment message instructs the storage device to adjust a performance parameter of the storage device. The compute device is also to send the adjustment message to the storage device.
