Key Features and Benefits
Designed for maximum flexibility, Cisco CDEs can be grouped into arrays that operate as a single
logical system. Service providers can easily expand capacity by simply attaching additional CDEs
to the array, thereby achieving virtually unlimited video storage and streaming capacity. The Cisco
CDS employs a unique hierarchical storage design that allows service providers to maintain huge
content libraries, while actually simplifying content storage management. With a logically
distributed architecture that can separate ingest and storage from streaming, each function can be
scaled independently of the other by simply adding another Cisco CDE—which dynamically
increases the pooled ingest, storage, caching, and streaming resources available throughout the
network.
Cisco CDEs adapt automatically to unpredictable and rapidly changing traffic patterns. The
platform preserves video programming in a common, shared storage array that is instantly
accessible for streaming anywhere in the network. Cisco’s Intelligent Caching technology
automates the distribution of video content between Cisco CDEs by responding dynamically to
actual viewer demand and popularity trends. This adaptive content distribution model helps ensure
that the content that is most popular at any point in time at each network node is always available
in local storage—reducing the bandwidth burden on the network backbone by 95 percent or more.
This flexible architecture and the effectively unlimited scalability of content libraries make the Cisco
CDS the industry’s only solution for efficiently and cost-effectively delivering long-tail content,
network-based time-shifted programming, and user-generated content. This serves to maximize
the network’s scalability while at the same time minimizing capital expenditures (CapEx) and
operating expenses (OpEx).
Cisco CDEs are also designed for fault-tolerant operation. They can share state and work together
as a single logical pool of resources that can be dynamically re-allocated across the network’s
available hardware capacity in response to service requests. In the event of hardware failure (if a
disk crashes, an I/O card fails, or even if an entire vault server goes down), the Cisco CDS
immediately delegates the functions being performed by the failed device to other Cisco CDEs in
