7.1.3 Security
The KVM redirection feature supports multiple encryption algorithms, including RC4 and AES. The actual
algorithm that is used is negotiated with the client based on the client’s capabilities.
7.1.4 Availability
The remote KVM session is available even when the server is powered-off (in stand-by mode). No re-start of
the remote KVM session shall be required during a server reset or power on/off. A BMC reset (e.g. due to a
BMC Watchdog initiated reset or BMC reset after BMC FW update) will require the session to be re-
established.
KVM sessions persist across system reset, but not across an AC power loss.
7.1.5 Usage
As the server is powered up, the remote KVM session displays the complete BIOS boot process. The user is
able interact with BIOS setup, change and save settings as well as enter and interact with option ROM
configuration screens.
At least two concurrent remote KVM sessions are supported. It is possible for at least two different users to
connect to same server and start remote KVM sessions
7.1.6 Force-enter BIOS Setup
KVM redirection can present an option to force-enter BIOS Setup. This enables the system to enter F2 setup
while booting which is often missed by the time the remote console redirects the video.
7.2 Media Redirection
The embedded web server provides a Java applet to enable remote media redirection. This may be used in
conjunction with the remote KVM feature, or as a standalone applet.
The media redirection feature is intended to allow system administrators or users to mount a remote IDE or
USB CD-ROM, floppy drive, or a USB flash disk as a remote device to the server. Once mounted, the remote
device appears just like a local device to the server, allowing system administrators or users to install software
(including operating systems), copy files, update BIOS, and so on, or boot the server from this device.
The following capabilities are supported:
 The operation of remotely mounted devices is independent of the local devices on the server. Both
remote and local devices are useable in parallel.
 Either IDE (CD-ROM, floppy) or USB devices can be mounted as a remote device to the server.
 It is possible to boot all supported operating systems from the remotely mounted device and to boot from
disk IMAGE (*.IMG) and CD-ROM or DVD-ROM ISO files. See the Tested/supported Operating System
List for more information.
 Media redirection supports redirection for both a virtual CD device and a virtual Floppy/USB device
concurrently. The CD device may be either a local CD drive or else an ISO image file; the Floppy/USB
device may be either a local Floppy drive, a local USB device, or else a disk image file.
 The media redirection feature supports multiple encryption algorithms, including RC4 and AES. The
actual algorithm that is used is negotiated with the client based on the client’s capabilities.
 A remote media session is maintained even when the server is powered-off (in standby mode). No restart
of the remote media session is required during a server reset or power on/off. An BMC reset (e.g. due to
an BMC reset after BMC FW update) will require the session to be re-established
 The mounted device is visible to (and useable by) managed system’s OS and BIOS in both pre-boot and
post-boot states.
 The mounted device shows up in the BIOS boot order and it is possible to change the BIOS boot order to
boot from this remote device.
 It is possible to install an operating system on a bare metal server (no OS present) using the remotely
mounted device. This may also require the use of KVM-r to configure the OS during install.
USB storage devices will appear as floppy disks over media redirection. This allows for the installation of
device drivers during OS installation.
