High-performance storage systems and networks have spawned a number of new applications in recent years. Among these is the storage and retrieval of digital video. Digital video puts several new demands on the storage system and network, including:

• Larger storage capacity requirements (a 1.5Mbps MPEG-1 encoded video requires approximately 500MB for a 60-minute clip)
• Larger network bandwidth requirements (a VHS-quality video clip requires 1.5Mbps to 8Mbps)
• Guaranteed access to storage and network resources over a long period of time
• Low latency for interactive requests
• Tighter service timing, to provide a near-constant-bitrate stream

• Embedded execution in a NASD drive
• Low startup latency, especially when serving short clips
• Compatibility with the Informedia project's database and search software
