3 Using VRTX KVM and DVD
Introduction
The VRTX Chassis is a converged infrastructure solution that combines four separate compute nodes,
network infrastructure, and a shared storage subsystem. This paper will cover the usage of KVM and
DVD.
With KVM, the user can connect the monitor, keyboard, and mouse to the VRTX Chassis, assign it to
one of the servers, and then use them. DVD is an optional module in the VRTX chassis and it can be
assigned to one of the servers and used.
KVM Configuration and Selection
In PowerEdge M1000e, the KVM is a pluggable module. But in VRTX Chassis, the KVM is inbuilt in the
Chassis and a part of the chassis infrastructure. The KVM can either be unmapped (that is, not
assigned to any server), or assigned to one of the servers. It is also possible to enable or disable the
KVM availability for each of the server individually. If the KVM is disabled for a server, the KVM
cannot be assigned to that server. The KVM configuration or control can be done from LCD on the
VRTX Chassis, the CMC Web interface, or running RACADM commands at the command line interface
(CLI).
KVM Configuration from RACADM
The current KVM configuration can be viewed using the following command.
$ racadm getconfig -g cfgkvminfo
cfgKvmMapping=1
cfgKvmSlot1Enable=1
cfgKvmSlot2Enable=1
cfgKvmSlot3Enable=1
cfgKvmSlot4Enable=1
The KVM assignment can be changed by running the following command. The KVM mapping value has
to be 0 for Unmapping, and 1–4 for mapping to the corresponding server.
$ racadm config -g cfgkvminfo -o cfgKvmMapping 0
Object value modified successfully
$ racadm config -g cfgkvminfo -o cfgKvmMapping 3
Object value modified successfully
