Abstract: In one embodiment, an apparatus comprises a storage device to receive, from a computing host, a request to append data to a data log. The storage device is further to identify a memory location after a last segment of the data log, append the data to the data log by writing the data to the memory location after the last segment of the data log, and provide, to the computing host, a key comprising an identification of the memory location at which the data was appended to the data log.

Abstract: Technology for an apparatus is described. The apparatus can include a memory and a storage controller. The storage controller can be configured to receive a search command with one or more parameters that instructs the storage controller to search for a data pattern in data stored in the memory. The storage controller can be configured to search the data stored in the memory for the data pattern according to the one or more parameters included in the search command. The storage controller can be configured to locally search the data in the memory for the data pattern without transferring the data to a processor to perform the search.

Abstract: In one embodiment, the present invention includes a method for maintaining a sequence of writes into a disk cache, where the writes correspond to disk write requests stored in the disk cache, and ordering cache writes from the disk cache to a disk drive according to the sequence of writes. In this way, write ordering from an operating system to a disk subsystem is maintained. Other embodiments are described and claimed.

Abstract: Write operations store data in different physical memory locations. Each of the physical memory locations are associated with a logical address that is shared in common among the physical addresses. Sequence information stored in the physical memory location indicates which one of the write operations occurred last. The available erased memory location can be split into a list of erased memory locations available to be used and a list of erased memory locations not available to be used. Then, on a failure, only the list of erased memory locations available to be used needs to be analyzed to reconstruct the consumption states of memory locations.

Abstract: A volatile or nonvolatile cache memory can cache mass storage device read data and write data. The cache memory may become inaccessible, and I/O operations may go directly to the mass storage device, bypassing the cache memory. A log of write operations may be maintained to update the cache memory when it becomes available.

Abstract: A system and method to reduce the time for system initializations is disclosed. For at least one embodiment, data accessed during a system initialization is loaded into a non-volatile cache during shutdown or entry into a low-power mode. On a subsequent boot, or resumption after a low power mode, the data required for system initialization has already been pre-loaded into the cache, thereby eliminating the need to access a disk. Other embodiments are also described and claimed.

Abstract: In some embodiments, a method to keep volatile disk caches warm across reboots is presented. In this regard, a caching agent is introduced to, responsive to a system boot, load a cache data from a reserved portion of a mass storage device into a memory. Other embodiments are also disclosed and claimed.
