Abstract: A storage device for providing data storage services to a host includes persistent storage for storing a file and a controller. The controller obtains a write request from the host for the file, the write request comprises a command packet; perform processing of the command packet using a payload portion of the file; generate a response packet based on the processing of the command packet; and store the response packet in a response portion of the file in response to the write request.

Abstract: A storage device for providing data storage services to a source host and a destination host includes persistent storage and a controller. The controller obtains a handoff initiation request for a handoff of storage resources of the persistent storage allocated to the source host, the handoff initiation request specifies that the storage resource is to be handed off to the destination host; in response to obtaining the handoff initiation request: quiesces the storage resource; terminates use of the storage resource by the source host after quiescing the storage resource; after terminating the use of the storage resource by the source host, connects the destination host to the storage resource; and after connecting the destination host to the storage resource, enables use of the storage resource by the destination host.

Abstract: A method for managing persistent storage. The method includes selecting a page for a proactive read request, where the page is located in the persistent storage. The method further includes issuing the proactive read request to the page, receiving, in response to the proactive read request, a bit error value (BEV) for data stored on the page, obtaining a BEV threshold (T) for the page, wherein T is determined using a program/erase cycle value associated with the page and a retention time of the data stored on the page, making a first determination that the BEV is greater than T, based on the first determination: identifying an m-page, where the m-page is a set of pages and the page is in the set of pages, and setting the m-page as non-allocatable for future operations.

Abstract: A method for adaptively migrating data in solid state memory. The method includes making a first determination that a write limit of a first region of the solid state memory has been reached, and based on the first determination, allocating a second region of the solid state memory, writing a pre-migration marker to each memory location of the second region and receiving a first request to read a data fragment from a first logical address. The method further includes identifying a first memory location in the second region based on the first logical address, making a second determination that a first data fragment at the first memory location comprises a pre-migration marker, and based on the second determination, identifying a second memory location in the first region, based on the first logical address, and writing a second data fragment, retrieved from the second memory location, to the first memory location.

Abstract: In general, the technology relates to a method and system for writing data to persistent storage. More specifically, embodiments of the technology relate to writing data to vaulted memory segments in persistent storage using pre-defined multicast address groups. Further, embodiments of the technology take into account the current state of the persistent storage in order to select the vaulted memory segments in which to store the data.

Abstract: A method for data migration in solid state memory. The method includes making a first determination that a write limit of a first memory region of the solid state memory has been reached, and based on the first determination: allocating a second memory region in the solid state memory. The method further includes, based on making the first determination: migrating a first data fragment from a first memory location in the first memory region to a corresponding second memory location in the second memory region, updating a migration progress index to include the second memory location, directing future read and write requests that target memory locations included in the migration progress index to the second memory region, and directing future read and write requests that target memory locations not included in the migration progress index to the first memory region.

Abstract: In general, embodiments of the technology relate to writing data to and reading data from storage appliances. More specifically, embodiments of the technology describe a method and system whereby a global control mechanism may be established, with delegation of specific translation activities to particular storage media device.

Abstract: A method for managing a storage appliance. The method includes determining an input/output (I/O) workload characterization (IWC) for the storage appliance. The method further includes determining an optimized temperature for the storage modules in the storage appliance based on the IWC, determining that a current temperature of the storage modules is not the optimized temperature, and modifying operation of at least one active cooling component in the storage appliance to change the current temperature of the storage modules to the optimized temperature.

Abstract: A method for writing data to a storage pool. The method includes receiving a virtual identifier (ID) and an offset for an object, extracting a node identifier (ID) that identifies a first storage server in the storage pool from the virtual ID, obtaining an object layout (OL) for the object from the first storage server, hashing an object ID and an offset ID to obtain a hashed value, where the virtual ID comprises the object ID and where the offset ID is generated from the offset, identifying a second storage server in the storage pool using a global namespace layout (GL), the OL, and the hashed value, and issuing a write request to write data to the object in the second storage server, where the write request comprises the object ID and the offset.
