DYNAMIC MEDIA CACHE FOR A DATA STORAGE DRIVE IN AN INFORMATION HANDLING SYSTEM

摘要

A drive controller associated with a data storage medium may receive a command from a host to write a set of data to a storage space of the data storage medium. The drive controller may determine that insufficient space is available in a cache space of the data storage medium to write the set of data to the cache space and may dynamically convert an available portion of the storage space into a dynamic cache space associated with the cache space. The dynamic cache space may remain visible to the host as the available portion of the storage space. The drive controller may then write the set of data to the cache space and report to the host that the set of data is written to the storage space of the data storage medium.

1. A method comprising:
receiving, by a drive controller, a command from a host to write a set of data to a storage space of a data storage medium associated with the drive controller; determining, by the drive controller, that insufficient space is available in a cache space of the data storage medium to write the set of data to the cache space; by the drive controller and based on determining that insufficient space is available in the cache space, dynamically converting an available portion of the storage space into a dynamic cache space associated with the cache space, wherein the dynamic cache space remains visible to the host as the available portion of the storage space; and writing, by the drive controller in response to dynamically converting the available portion into the dynamic cache space, the set of data to the cache space.
