    摘要： Various implementations described herein relate to systems and methods for dynamically managing buffers of a storage device, including receiving, by a controller of the storage device from a host, information indicative of a frequency by which data stored in the storage device is accessed, and in response to receiving the information determining, by the controller, the order by which read buffers of the storage device are allocated for a next read command. The NAND read count of virtual Word-Lines (WLs) are also used to cache more frequently accessed WLs, thus proactively reducing read disturb and consequently increasing NAND reliability and NAND life.

    摘要： A computer-implemented method for accessing data stored in a virtual tape storage (VTS) system, according to one embodiment, include receiving a mount request to access at least one host data record in a VTS system, issuing a locate command to position the sequential access storage medium having the logical volume stored therein to about a position where the physical block having at least a portion of the requested at least one host data record therein is located; creating a partial virtual volume in a tape volume cache; and copying the physical block having the at least a portion of the requested at least one host data record therein from the sequential access storage medium to the partial virtual volume in the tape volume cache. An amount of data copied from the logical volume to the partial virtual volume is less than the amount of data in the logical volume.
