Industry-leading
MPEG2TSstream density
MPEG2TSstream density
With up to 8000 MPEG2 standard-definition (SD) streams in a two-rack-unit (2RU) form factor, the Cisco CDE 250
Dense TV Streamer offers industry-leading video streaming density (4000 SD streams per RU). This translates to
over 176,000 MPEG2 SD streams served with a single rack, optimizing space requirements and reducing total
ownership costs.

MPEG2T storage
The Cisco CDE 250 combined with VDS-TV CDA offers a high-end Content Library capable of reliably storing up to
12,000 hours of MPEG2 SD content in a two-rack-unit (2RU) form factor, allowing service providers to expand their
content library with a small number of library servers.

Flash memory SSD technology complements hard-disk-drive (HDD) options for certain Cisco CDE configurations.
The technology is used for video cache and transaction logging to lower operating costs and lay the foundation for
even better performance and scale.

VDS-TV resource pooling and load balancing allow Cisco CDEs to be networked into logical server arrays that can
provide effectively unlimited amounts of content storage (content library array), content cache (caching node array),
and streaming capacity (streamer array) throughout the network.

Additional streaming or storage capacity can be added to the array without outages or service interruption. The Cisco
VDS TV detects the addition or removal of Cisco CDEs from the logical array and optimally load balances the entire
resource pool.

Generation 3 Content Delivery Engines: Cisco CDE 250 Models
The latest generation of Cisco Content Delivery Engines, the Cisco CDE 250, employs leading-edge server
technology to deliver higher scalability, performance, and flexibility in a dense 2RU design. A multitier product
structure provides flexibility at the storage system level while simplifying the underlying server product across all
applications. Each Cisco CDE 250 storage bundle is optimized for the Cisco Content Delivery Applications (CDAs)
that are supported on it, as shown in Table 3. The 10-Gigabit Ethernet I/O uses Enhanced Small Form-Factor
Pluggable (SFP+) modules to support both fiber and copper media on a per-port basis.
