Avocent DSR Series - KVM over IP

Avocent- Digital KVM Switch

The DSR builds on the success of the DS1800 in providing secure KVM connections to virtually any number of servers using the power of the Internet. The DSR was developed in response to today's new requirements for server access, anywhere, anytime.

How It Works

Because DSR leverages industry standard LAN equipment, complex wired configurations are no longer necessary. All of the analogue KVM signals are converted in real time to digital form and transported using standard Ethernet protocols. This data is then fed into compression engines, which compare the information already transmitted to the operator with the new information presented from the server. Once those changes are analysed, they are sent to a high-powered processor, which packs the information and transmits it via the Internet to the operator. This user can now view the computer video through a PC-based application program called DSView.

DSView - New DSView 3

DSView shows the user a list of computers that he has permission to connect to. Once the user has chosen one of the computers, a connection is established between DSView and the appropriate port on a DSR. Video data is then sent from the DSR to DSView. The remote computer screen image is then scaled to fit appropriately into the window on the PC desktop that is running DSView. This allows multiple computers to be viewed simultaneously, each displayed in its own window. These windows can be arranged on the desktop in any manner desired.

DSView® 3 software, with hub and spoke architecture, increases security with failover authentication. Users authenticate to a central management server (the hub) or one of 15 mirror servers (the spokes). SNMP and IPMI support are also provided.

DSI5100 IPMI Proxy Appliance

The Avocent® DSI5100 IPMI proxy appliance adds new capabilities to the proven DS Series data center solutions. Power management is a significant benefit to accessing Intelligent Platform Management Interface (IPMI) ? Avocent OSA technology embedded in servers for remote out-of-band access to sensors on target devices. IT administrators also can monitor and control system health including the temperature, fan, and voltage. With power and system health monitoring now internal on IPMI-enabled servers, you can know exactly which server needs attention. Because IPMI data is stored on a stand-alone processor independent of the OS, BIOS and CPU, you can use IPMI even when the operating system is unresponsive.


Customers can decide if they wish to connect the DSR to their existing LAN, or create a separate out-of-band LAN just for maintenance of their servers. Burst loads of approximately 20 to 30 Mbits per second are reached during full high-resolution screen refreshes.


Typical installations may expect ten to twenty operators to be simultaneously viewing and controlling servers on a single 100Mbit collision domain. In most cases, they will see near real-time performance on any connection.
