Abstract: Technologies for hybrid sleep power management include a computing device with a processor supporting a low-power idle state. In a pre-boot firmware environment, the computing device reserves a memory block for firmware use and copies platform wake code to a secure memory location, such as system management RAM (SMRAM). At runtime, an operating system may execute with the processor in protected mode. In response to a request to enter a sleep or suspend state, the computing device generates a system management interrupt (SMI). In an SMI handler, the computing device copies the wake code from SMRAM to the reserved memory block. The computing device resumes from the SMI handler to the wake code with the processor in real mode. The wake code enters the low-power idle state and then jumps to a wake vector of the operating system after receiving a wake event. Other embodiments are described and claimed.

Abstract: Live imaging of a device can be performed. A client device can include at least two drives that are alternately employed to store the active OS partition. An imaging solution that executes on the active OS partition on a first drive can perform a live imaging process in which a second drive is fully imaged while the user continues to use the client device.

In this way, the only downtime that a user may experience due to the imaging process is during the reboot. In a similar manner, when a client device includes only a single available drive, the drive can be divided into two or more sets of one or more partitions that are alternately employed as the active OS partition(s).

An example includes determining whether a base address of a virtual address segment in a persistent memory has changed.

Then, a present location of a virtual address of an associated data structure of the primary data structure in the virtual address segment is determined. The offset value is used to relocate the virtual address of the associated data structure of the primary data structure from a current location to another location in the persistent memory.

Abstract: A technique for managing storage in a data storage system includes ingesting host data into a data log backed by pages in a cache. The host data are addressed to specified locations in a data object stored in persistent storage devices. When mapping pages in cache to respective target locations in the persistent storage devices, a flag is selectively asserted to indicate whether there is contiguous free space at the target locations. The cache responds to the flag by delaying flushing of flagged pages, which provides more time for the cache to aggregate pages that map to contiguous free space. Meanwhile, pages that are not flagged can be flushed more quickly, enabling the cache to operate efficiently even though flushing of some pages is delayed.

A new block header value is subsequently generated that includes the determined new block size and the determined remaining capacity of the page The original block header value is then replaced with the new block header value. Related apparatus, systems, techniques and articles are also described.

Abstract: A memory management service occupies a configurable portion of an overall memory system in a disaggregate compute environment. The service provides optimized data organization capabilities over the pool of real memory accessible to the system. The service enables various types of data stores to be implemented in hardware, including at a data structure level. Storage capacity conservation is enabled through the creation and management of high-performance, re-usable data structure implementations across the memory pool, and then using analytics (e.g., multi-tenant similarity and duplicate detection) to determine when data organizations should be used. The service also may re-align memory to different data structures that may be more efficient given data usage and distribution patterns. The service also advantageously manages automated backups efficiently.
