Abstract: Examples include techniques for determining a storage policy for storing data in a computing system having one or more storage nodes, each storage node including one or more storage devices. One technique includes getting rating information from a storage device of a storage node; assigning the storage device to a storage pool based at least in part on the rating information; and automatically determining a storage policy for the computing system based at least in part on the assigned storage pool and the rating information.

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.
