A Comparison of Alternative Continuous Display Techniques with Heterogeneous Multi-Zone Disks

A number of recent technological trends have made data intensive applications such as continuous media audio and video servers a reality. These servers are expected to play an important role in applications such as video-on-demand, digital library, news-on-demand, distance learning, etc. Continuous media applications are data intensive and might require storage subsystems that consist of hundreds of multi-zone disk drives. With the current technological trends, a homogeneous disk subsystem might evolve to consist of a heterogeneous collection of disk drives. Given such a storage subsystem, the system must continue to support a hiccup-free display of audio and video clips. This study describes extensions of four continuous display techniques for multizone disk drives to a heterogeneous platform. These techniques include IBM's Logical Track 21 , HP's Track Pairing 4 , and USC's FIXB 9 and dead-line driven techniques 10 . We quantify the performance tradeo associated w...
