    Abstract: A method includes allocating random write resources to a first portion of a zone having a range of LBAs and a cache storing data of the first portion of the zone. A write command is received including an LBA. The LBA is mapped to a PBA of the cache using a first L2P table. Each of one or more LBAs in the range of LBAs of the first portion of the zone is mapped to a corresponding PBA of the cache using entries of the first L2P table. A range of sequential LBAs of a second portion of the zone is mapped to a physical block of the zone. Each LBA of the range of sequential LBAs is accessed using an offset corresponding to a position of each LBA in the range of sequential LBAs of the second portion of the zone. The write command is executed at the PBA.

    Abstract: The present technology includes a storage device including a memory device including a first storage region and a second storage region and a memory controller configured to, in response to a write request in the first storage region from an external host, acquire data stored the first region based on a fail prediction information provided from the memory device and to perform a write operation corresponding to the write request, wherein the first storage region and the second storage region are allocated according to logical addresses of data to be stored in by requests of the external host.

    Abstract: Systems and methods are described for implementing a multi-tenant caching service. The multi-tenant caching service provides a scalable infrastructure with dedicated per-tenant cache widths for tenants of a hosted computing environment, and allows tenants to implement a caching layer between cloud-based services that would otherwise need to scale up in response to load. Tenants may also use the service as a public facing endpoint that caches content provided by backend servers. Content provided by the tenants may be distributed and cached across a cell-based architecture, each cell of which may include a set of storage volumes that are partitioned into caches for individual tenants and configured to store a portion of the content provided by that tenant. Eviction policies may be implemented based on tenant cache usage across multiple cells, and geolocation policies may be implemented to ensure that cached content remains within a particular geographic region.
