The Cisco Media Delivery Engine (MDE) 1100 is part of the Cisco Enterprise Content Delivery System (ECDS), an overall media delivery system that helps organizations easily scale video and media delivery over their existing WAN infrastructure. The Cisco MDE 1100 is a dedicated appliance that can run all the ECDS applications, including the Service Engine, Service Router, and Content Delivery System Manager. The Cisco MDE 1100 is ideal for small-site deployments that require less than 500 simultaneous users and clients for media delivery. MDE appliances may be stacked together to provide greater scalability for larger sites. The Cisco MDE 1100 provides one TB of total storage, including up to 800 GB for prepositioning and dynamic caching of the content.
