20230236761 · 2023-07-27 ·

A read-disturb-based logical storage read temperature identification system includes a global read temperature identification subsystem coupled to at least one storage device. Each at least one storage device identifies read disturb information associated with rows provided by the at least one physical block in that storage device from at least one physical block in that storage device, and maps the read disturb information associated with the rows provided by the at least one physical block in that storage device to one or more logical storage elements included in a logical-to-physical storage element mapping for that storage device to generate a local logical storage element read temperature map. Each at least one storage device may then provide its local logical storage element read temperature map to the global read temperature identification subsystem.

Technology for moving data between virtual machines without copies

A processor comprises a core, a cache, and a ZCM manager in communication with the core and the cache. In response to an access request from a first software component, wherein the access request involves a memory address within a cache line, the ZCM manager is to (a) compare an OTAG associated with the memory address against a first ITAG for the first software component, (b) if the OTAG matches the first ITAG, complete the access request, and (c) if the OTAG does not match the first ITAG, abort the access request. Also, in response to a send request from the first software component, the ZCM manager is to change the OTAG associated with the memory address to match a second ITAG for a second software component. Other embodiments are described and claimed.

DYNAMICALLY ALLOCATABLE PHYSICALLY ADDRESSED METADATA STORAGE

In examples there is a computing device comprising a processor, the processor having a memory management unit. The computing device also has a memory that stores instructions that, when executed by the processor, cause the memory management unit to receive a memory access instruction comprising a virtual memory address; translate the virtual memory address to a physical memory address of the memory, and obtain permission information associated with the physical memory address. Responsive to the permission information indicating that metadata is permitted to be associated with the physical memory address, a check is made of a metadata summary table stored in the physical memory to check whether metadata is compatible with the physical memory address. Responsive to the check being unsuccessful, a trap is sent to system software of the computing device in order to trigger dynamic allocation of physical memory for storing metadata associated with the physical memory address.

20230023307 · 2023-01-26 ·

Linked clone read performance (e.g., retrieving data) is improved at least by minimizing the number of input/output (I/O) operations. For a child clone, a local logical extent and an inherited logical extent are generated. The local logical extent comprises a logical block address (LBA) for data in a data region of the child clone and a physical sector address (PSA) corresponding to the LBA for the data in the data region of the child clone. The inherited logical extent spans logical extents that are accessible to the child clone. The inherited logical extent comprises an LBA for data in a data region of an ancestor of the child clone and a corresponding identifier (ID) of the ancestor. Data for an LBA in a read request may be rapidly found in the child clone (local logical extent) or an ancestor (inherited logical extent).

In a server system, a host computing platform can have a processing unit separate from the host processor to detect and respond to failure of the host processor. The host computing platform includes a memory to store data for the host processor. The processing unit has an interface to the host processor and the memory and an interface to a network external to the host processor and has access to the memory. In response to detection of failure of the host processor, the processing unit migrates data from the memory to another memory or storage.
