Problems solved by technology

[0009] Ultimately, conventional reconfiguration procedures do not address the effects of changes in storage device characteristics over time caused by storage media degradation
Such a change will make the original feature selection in a specific use environment no longer valid

Abstract

The present invention discloses a reconfigurable storage device. Exemplary embodiments for reconfiguring a storage system comprise receiving user requirement information for a storage device and automatically generating feature settings for the storage device from the user requirement information and a device profile for the storage device; and using the feature settings to automatically reconfigure the storage device into one or more logical devices having independent behavioral characteristics. Further exemplary embodiments comprise receiving feedback from the storage device regarding runtime performance data of at least one of the storage device and the logical devices; and responsive to a determination that the runtime performance data do not satisfy the user requirement information, dynamically adjusting configuration of the one or more logical devices to meet the user requirement information.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2012-0005764 filed in the Korean Intellectual Property Office on Jan. 18, 2012, the entire contents of which are hereby incorporated by reference. Background technique [0003] Modern memory systems typically include multiple independent passive memory devices whose performance characteristics are usually fixed at the time of manufacture. A processor (such as a RAID controller) is required to execute software (firmware) to add intelligence to make a collection of non-intelligent storage devices work as a unit. Since a storage device such as a solid state disk (SSD) can also be controlled by software or firmware, attempts have been made to control the operating characteristics of the solid state disk according to usage environments. [0004] Traditional approaches for meeting user qualification testing require manufacturers to provide last-minute proces...
