Abstract: In various embodiments, a storage device includes a magnetic media, a cache memory, and a drive controller. In embodiments, the drive controller is configured to establish a portion of the cache memory as an archival zone having a cache policy to maximize write hits. The drive controller is further configured to pre-erase the archival zone, direct writes from a host to the archival zone, and flush writes from the archival zone to the magnetic media. In embodiments, the drive controller is configured to establish a portion of the cache memory as a retrieval zone having a cache policy to maximize read hits. The drive controller is further configured to pre-fetch data from the magnetic media to the retrieval zone, transfer data from the retrieval zone to a host upon request by the host, and transfer read ahead data to the retrieval zone to replace data transferred to the host.

Abstract: In accordance with the present disclosure, a system and method for performing a system memory save in tiered or cached storage during transition to a decreased power state is disclosed. As disclosed herein, the system incorporating aspects of the present invention may include a solid-state drive, volatile memory, and at least one alternate storage media. Upon transition to a decreased power state, at least some of the data in the solid-state drive may be transferred to the at least one alternate storage media.

Abstract: Methods and systems for offloading data to a remote storage resource from a local storage resource on an information handling system may involve using a data location management agent and an offload mapping. The data location management agent may detect requests for access to files stored on a file system and may offload files to the remote storage resource to maintain a specified available capacity of the local storage resource, based on at least in part on the offload mapping. The data location management agent may classify certain files as pinned files that are excluded from offloading.

Abstract: A forced power down signal issues from an I/O device to an information handling system through an optical interconnect if the information handling system fails to power down in response to a normal power down message. A 100% duty cycle signal issues from an optical interface at the I/O device and is detected by an optical interface of the information handling system, which issues a command to force a power down of the information handling system in response to the forced power down signal.
