Industry-leading stream
density
density
With up to 2,500 MPEG2 SD streams in a 2 rack unit form factor, the CDE220 Dense TV Streamer offers industry-
leading video streaming density (1250 SD streams/RU). This translates to over 56,000 MPEG2 SD streams served
with a single rack, optimizing space requirements and reducing total ownership costs.

The CDE420 high-end vault is capable of reliably storing up to 12,000 hours of SD MPEG2 content, providing service
providers the ability to expand their content library with a small number of library servers.

Flash SSD technology
Flash SSD technology complements hard disk drive options for certain CDE configurations. The technology is used for
video cache and transaction logging to lower operational costs and lay the foundation for even higher performance and
scale.

Solid state boot device
8 GB compact flash guarantees reliable boot-up operations with ample capacity to spare.
Dual port management

Nonstop service availability Unique failover and resiliency features help ensure that hardware failures don't bring down the network and cause
service outages.
Resource pooling and load balancing enable Cisco CDEs to be networked into logic server arrays that can provide
virtually unlimited amounts of content storage (vault array), content cache (caching node array) and streaming capacity
(streamer array) throughout the network.

(streamer array) throughout the network.
Additional streams or storage capacity can be added to the array without outages or service interruption. The Cisco
CDS detects when new CDEs are added or removed from the logic array and optimally load-balances the entire
resource pool.

Logic server arrays
Independent scaling of content library size and stream count allows flexibility in capital expenditures.
Multifunction capabilities
Cisco CDE models are built on a few select base systems with minor differences among the available configurations,
simplifying personnel training and equipment sparing strategies.

Cisco Content Delivery Engine Models
The latest generation of Cisco Content Delivery Engines offers higher scalability and performance in a dense design.
There are four products in this new generation: CDE110, CDE205, CDE220, and CDE420. Each CDE is optimized
for the Cisco Content Delivery applications that are supported on it, as shown in Table 1. Table 3 shows a high-level
summary of all Cisco CDEs.
