Embodiments relate to systems and methods for managing stalled storage devices of a storage system. In one embodiment, a method for managing access to storage devices includes determining that a first storage device, which stores a first resource, is stalled and transitioning the first storage device to a stalled state. The method also includes receiving an access request for at least a portion of the first resource while the first storage device is in the stalled state and attempting to provide access to a representation of the portion of the first resource from at least a second storage device that is not in a stalled state. In another embodiment, a method of managing access requests by a thread for a resource stored on a storage device includes initializing a thread access level for an access request by a thread for the resource. The method also includes determining whether the storage device, which has a device access level, is accessible based at least in part on the thread access level and the device access level and selecting a thread operation based at least in part on the determination of whether the storage device is accessible. The thread operation may be selected from attempting the thread access request if the device is accessible and determining whether to restart the thread access request if the device is not accessible.

A system and method are disclosed for eliminating many of the transactional performance limitations in current digital media server systems by augmenting those existing systems with an adaptable cache. In a preferred embodiment, the adaptable cache is a compact storage device that can persist data and deliver it at an accelerated rate, as well as act as an intelligent controller and director of that data. Incorporating such an adaptable cache between existing storage devices and an external network interface of a media server, or at the network interface itself, significantly overcomes the transactional limitations of the storage devices, increasing performance and throughput for the overall digital media system. The adaptable cache of the present system and method may preferably be integrated directly into the storage and delivery pipelines, utilizing the native communications busses and protocols of those subsystems.
