Abstract
Techniques for improving access time in data storage systems are disclosed. These techniques can be used to prevent undesirable access delays that are often experienced in conventional storage systems. “Slow-access” can be defined as an access operation that does not successfully complete within a predetermined amount of time. The “slow-access” time can, for example, be defined based on a system requirement, specification, or a particular need of a specific application. As such, when detected “slow-access” indicates a potential performance problem that can manifest in undesirable effects. A data storage system is evaluated for potential performance problems by scanning it for “slow-access.” In addition, preventative measures are taken to prevent occurrence of a “slow-access” once it has been identified. These measures can prevent the undesirable effects experienced in conventional storage systems. This also means that specific system or application requirements can be certified and met.
