Title
Stripe-cache: an efficient cache scheme for building multimedia oriented RAID system
Abstract
The design of the underlying storage subsystems for multimedia applications faces significant challenges for capability high I/O performance and availability requirements. A RAID system is defined as a storage system that distributes data redundantly across array of disks and can provide high throughput as well as higher availability. In this paper, we present a novel cache scheme (for short Stripe-cache) for building a multimedia oriented RAID system. This efficient stripe-cache has the following innovations: (1) Hierarchy architecture with different block structure according to the underlying data layout that exploits temporal locality and spatial locality (2) Timing-transfer and replacing scheme forwardly move data block in cache for special efficiency. We built up the multimedia oriented RAID system as a device driver module upon the X86-Linux platform with the stripe-cache. Evaluation results show that the system can offer much higher I/O performance in handling multimedia applications than lots of conventional storage systems.
