W
ith integrated KVM (keyboard, video, mouse)
technology, Dell Remote Console Switches enable
administrators to manage servers regardless of location.
Like the previous-generation Dell 2161DS switch, the
Dell 2161DS-2 allows for simultaneous access by two
remote users and one local user. The Dell 4161DS switch,
however, allows for simultaneous access by up to four
remote users, or three remote users and one local user
(see Figure 1).
The Dell 2161DS-2 and 4161DS switches both feature
Digital Share Mode, which allows multiple users to access
the same server simultaneously. In addition, the 2161DS-2
and 4161DS include performance enhancements over
previous-generation Dell Remote Console Switches. These
switches use an algorithm developed by Avocent called
Dambrackas Video Compression™ (DVC). Specifically
optimized for interactive user sessions of KVM over IP,
DVC provides extremely high compression rates for video
data. This technology enables a near–real-time experience
by improving color depth (15-bit rather than 7-bit) and
by minimizing mouse response latency.
Encryption and compression algorithms are also
embedded in the switch hardware. Video quality through
local and remote sessions can achieve resolutions of up to
1,024×768. A higher resolution of 1,280×1,024 can be
obtained with specialized adapters for local sessions. With
the Dell 2161DS-2 and 4161DS switches, interfacing with
remote systems can be just like using the keyboard, video,
and mouse that are directly attached to the computer.
