20.6 Summary
In this chapter, we presented an efficient disk-array-based server design for the Super-Scalar
VoD system. We proposed a placement scheme to exploit disk zoning and the characteristics of
static and dynamic channels. Coupled with an integrated scheduler, we were able to increase
the server capacity by as much as 60% compared to the conventional GSS-based server design.
While the server design presented in this chapter is specifically targeted for use in a SS-VoD
system, the design principles are general and thus can be applied to other multicast video
streaming architectures with both periodic and aperiodic multicast streaming channels.
