The key to overcoming the limitation of any KVM switch
system is to take a different view of the components and how
they are inter-connected. This technology overview of
Three Tier Deployments detail the design techniques developed by Tron in
1998 to achieve a higher number of user workstations (access
points).
It also became the standard for increasing the number of servers
and workstations accessible on a common backbone.
KVM Switch (KVMS) marketing collateral claims to support more than eight
to ten thousand server devices on the same KVM Network
infrastructure. Using the topologies detailed in product manuals
requires a contention trade-off. Meaning a limited number of users
would have access to all servers on the KVM switch system.
Contention, also called Blocking is the result of closed
access designs (those demonstrated in KVM switch product manuals).
The three tier topology provides open access with support for more
than the maximum sixteen users (ie: 16x64 KVM switch matrix). An
Open Access design supports over 250 user workstations
with unblocked access to over 10,000 servers.
Above I reference complete access across an entire remote management
infrastructure. By segmenting peices of the infrastructures' backbone,
you can increase security and limit accessibility to servers by different
user groups or combine
Real-Time Analog (High Resolution) and KVMoIP
access concurrently.
The following pages include sample schematics that focus on unblocked
access with high user throughput. This HTML version is complimented by
a PDF version that include sample schematics to demonstrate how to
deploy a segmented Remote Management Infrastructure (RMI) .
