Question
Answer
Is virtual media secure?
Yes. Virtual media sessions are secured using
256-bit AES, 128-bit AES or 128-bit RC4
encryption.
Does virtual media really support
audio?
Yes. Audio playback and recording to a server
connected to the Dominion KX III is supported.
You can listen to sounds and audio playing on a
remote server in the data center using the
speakers connected to your desktop PC or
laptop. You can also record on the remote
server using a microphone connected to your
PC or laptop. A digital CIM or D2CIM-DVUSB
dual virtual media CIM is required.
What is a USB profile?
Certain servers require a specifically configured
USB interface for USB-based services such as
virtual media. The USB profile tailors the KX
IIKX IIII’s USB interface to the server to
accommodate these server-specific
characteristics.
Why would I use a USB profile?
USB profiles are most often required at the
BIOS level where there may not be full support
for the USB specification when accessing virtual
media drives. However, profiles are sometimes
used at the OS level, for example, for mouse
synchronization for Mac and Linux servers.
How is a USB profile used?
Individual ports or groups of ports can be
configured by the administrator to use a specific
USB profile in the KX III’s port configuration
page. A USB profile can also be selected in the
KX III Client when required. See the user guide
for more information.
Do I always need to set a USB
profile when I use virtual media?
No. In many cases, the default USB profile is
sufficient when using virtual media at the OS
level or operating at the BIOS level without
accessing virtual media.
What profiles are available? Where
can I find more information?
Consult the user guide for the available profiles
and for more information.
