Features and Benefits
Avocent’s DSR
™
appliances combine analog and digital technology to provide
flexible, centralized control of data center servers. This solution provides
enterprise customers with a significant reduction of cable volume, secure
remote access and flexible server management from anywhere at anytime.
The DSR appliance consists of a rack mountable keyboard, video and mouse
(KVM) switch configurable for analog (local) or digital (remote) connectivity.
Each DSR model has Avocent Rack Interface (ARI) ports for connecting
servers and serial devices via DSRIQ modules. Video resolution of 1280 x 1024
is supported for remote users of the DSR system. Enhanced video quality of
up to 1600 x 1280 is available for the local user via the keyboard, video and
mouse ports.
The DSR works over standard LAN connections. Users can access servers (or
serial devices) across a 100BaseT Ethernet connection or directly through a
local port on the DSR for remote KVM access and administration, depending
on the model selected. The IP-based DSR appliance gives you flexible server
management control from anywhere in the world.
Reduce cable bulk
With server densities continually increasing, cable bulk remains one of the
major concerns of every network administrator. The DSR significantly reduces
KVM cable volume in the rack by utilizing the innovative DSRIQ module and
single CAT 5 cabling. This allows a higher server density while providing
greater airflow and cooling capacity.
The built-in memory of the DSRIQ simplifies configuration by assigning
and retaining unique server names or Electronic ID ( EID) numbers for
each attached server. This integrated intelligence enhances security and
prevents unauthorized access to a server through cable manipulation. The
DSRIQ module is powered directly from the server and provides Keep Alive
functionality whether or not the DSR appliance is powered up.
The DSRIQ-SRL (serial) module is a DCE device that provides the primary
interface between a serial device and a DSR appliance. It provides VT100
terminal emulation, break suppression and port history in a convenient
module. The DSRIQ-SRL is compatible with the ARI port of a DSR system.
These DSRIQ modules eliminate the need for extra rack space or additional
cables. The connection between the DSR system and DSRIQ modules is via
industry standard UTP cabling.
