Reliability & Quality of Service Kasenna Cluster Manager New Movies … distributed across servers “Focused” usage pattern !! Server Cluster “Spread” usage pattern 1. Multiple servers clustered together to act as server system 2. Storage configuration includes content group + cache group 3. Content is distributed across servers 4. Playouts are spread across servers 5. If usage on track to exceed capacity of a server, content is automatically replicated to another server. 6. Cache is reclaimed once usage drops. 7. Load will be balanced across the server using standard protocols. = Popular Movie Title Cache !! … leads to demand spread. Benefits • Maximizes storage resources by using dynamic replication on an as-needed-basis • Built-in failure intelligence continues operations if a server node fails with • Automatic load management & replication guarantees quality of service – no need for the operator to intervene. • Easy to add more content & storage Copyright © 2006 Kasenna, Inc.
