Virtual Media
The appliance supports virtual media when connected to a VCo cable. You can use virtual
media support to connect USB media devices to the appliance and make those devices
available to any connected GCM2 or GCM4 appliance. Use virtual media to move data
between a target device and USB media devices that are connected to the appliance. You
can install, upgrade, or recover the operating system; update the BIoS code; or start the
target device from a USB drive through the virtual media capabilities of the appliance.
Key features and benefits
Virtual media can be connected directly to the appliance using one of four USB ports on
the appliance. In addition, virtual media can be connected to any remote workstation that
is running IBM Virtual Console Software (VCS) and is connected to the appliance using
an ethernet connection. To open a virtual media session with a target device, the target
device must first be connected to the appliance using a VCo cable.
Chaining Technology
IBM’s unique cable chaining solution enables users to manage a “daisy chain” of multiple
servers through a single connection to a console or KVM switch, replacing many long
cables with just a few short ones, simplifying rack management, helping lower cabling
cost and reducing setup, diagnostic, and maintenance times. The “daisy chain” connec-
tivity has the added advantage of thin, flexible industry-standard CAT5 cabling and
standard RJ-45 connectors removing the need for one-to-one, dedicated cable connec-
tions between KVM switch ports and managed devices. This cable chaining solution
allows up to 16 KCos or UCos to be chained together.
OSCAR® graphical user interface
The appliance uses the oSCAR interface, which has menus to configure the switching
system and select computers. You can list target devices by unique name, eID (electronic
ID), or port number. Use the oSCAR interface to protect the switching system with a
screen saver password. After a user-defined time, the screen saver mode engages and
access is prohibited until the correct password is entered to reactivate the switching
system.

Q. what is the ACI port used for?
A. The Analog Console Interface (ACI) port on each console switch is used to tier multiple switches together.
Detail: You can tier multiple console switches to enable one or two users to connect to up to 256 servers. In a tiered system, each ARI port on
the main console switch will connect to the Analog Console Interface (ACI) port on each tiered console switch. each tiered switch can then be
connected to up to 8 servers on the 1x8 console switch and up to 16 servers on the 2x16 console switch. The example in Figure 2.4 shows one
console switch tiered under the main switch, enabling the connection of up to 15 primary servers and 16 secondary servers. In this configuration, you
could tier 16 console switches under the main switch, enabling the connection of up to 256 servers. only one level of tiering is supported in this type
of configuration, which means that you cannot tier additional legacy switches or another console switch. In this configuration, the tiered local port
oSCAR interface is disabled when the main console switch is tiered below another console switch.
Q. what will I receive in the box with each Console Switch?
A. You will receive:
• Console switch

Q. what are the minimum hardware requirements for running VCS?
A. The software is supported on the following minimum computer hardware configurations:
• 500 Mhz Pentium III
• 256 MB RAM
• 10 or 100 BaseT NIC
• XGA video with graphics accelerator
• Desktop size must be a minimum of 800 x 600
• Color palette must be a minimum of 65,536 (16-bit) colors
Q. what are the different video session types that VCS supports?
A. when using the Video Viewer with GCM2 and GCM4 appliances, you have several options of session types. In addition to operating
a normal KVM session, administrators and users with certain access rights can also operate a session in an exclusive mode, share
the session with one or more users, observe a session in stealth mode, or scan multiple target devices. The current type of session is
indicated by an icon on the right side of the Video Viewer toolbar. Video session types are outlined below.
Normal KVM: You are conducting a normal KVM session that is not exclusive, but is not currently shared. An active session icon is visible.
Exclusive: You have exclusive control over the target device. During this KVM session the connection to the target device cannot be shared, but it
can be preempted or observed in stealth mode by an administrator.
Locked: Your administrator has configured the appliance to lock KVM and Virtual Media (VM) sessions together. You have a normal KVM session
and have opened a VM session. Your KVM session cannot be shared or preempted, and it is not subject to inactivity time-out. It can be terminated by
an administrator.
Digital share: active (primary)--you are the first user to connect to the target device, and you have allowed other users to share the KVM session.
Digital share: active (secondary)--you can view and interact with the target device while sharing the KVM session with a primary user and, possibly,
other secondary users.
Digital share: passive--you can view the video ouput of the target device, but you are not allowed to have keyboard and mouse control over the
target device.
Stealth: You can view the video output of the target device without the permission or knowledge of the primary user. You cannot have keyboard and
mouse control over the target device. This session type is available for administrators only.
Scanning: You can monitor up to 16 target devices in thumbnail view.
Virtual Media
Q. Are there any security issues when dealing with Virtual Media?
A. If someone starts a Virtual Media connection and then another person takes the KVM session (via preemption or a non-locked KVM
session being closed and then later opened by another user) while the first user’s Virtual Media session is active, they can access the
mapped VM device. (Note: This security issue exists whenever someone takes over a non-locked KVM session that has an active
(mapped) VM session).
Q. why can’t I use a VCo to access a computer’s BIoS?

A. The VCo is a composite USB 2.0 device. If the BIoS does not support (or supports in a limited fashion) USB 2.0 composite devices,
then the VCo can not work with it.
Q. why can’t I use a VCo to access a computer’s BIoS when I can hook up a keyboard, mouse, USB CDRom, and USB Mass Storage
Device to a USB hub attached to the same computer and they work?
A. The VCo is a composite USB 2.0 device. A USB hub acts as a compound device. The USB specification (and BIoS support) for
composite devices and compound devices are different, therefore it is possible for one to be supported, but not the other.
Q. why doesn’t my device show up in the Linux VM tool on the client computer?
A. The Linux VM tool reads the fstab and mtab to determine what to show. If your device is not listed in one of these two places, it
will not show up.
Q. why can I use the VCos capabilities once the oS has loaded, but not before?
A. Modern operating systems have USB drivers. when the BIoS detects an oS level driver loaded for the USB controller, it hands full
control of that controller to the oS.
Q. why can I only see the first partition on my USB hard drive when it is mapped via VM?
A. The USB specification has several different device types that a USB device can identify itself as. Based upon the device type the
USB device enumerates as, the oS will react differently to it. To allow enumeration at boot but still have the ability to connect and
disconnect Virtual Media as needed, a device type of Mass Storage Device must be used. windows only supports reading from the
first partition on a Mass Storage Device.
Q. why can’t I see a USB device attached to the appliance when I am using a remote connection (or corollary, why can’t I see my CD-
RoM drive from oSCAR)?
A. For conditions of security, VM only allows you to access devices that are in your physical control at the time the VM session is
began. Since there is no way to determine if the KVM appliance and client computer are in the same spot, the KVM appliance will
only allow people accessing VM via oSCAR to connect to a USB device attached to the KVM appliance and people accessing VM via
a remote connection to only access media on the client computer creating the VM session.
Q. The BIoS seems to see everything, but I can’t use the keyboard. why?
A. Since the VCo is a composite device, it can only negotiate one rate for all the pieces it enumerates as. This means that the
keyboard has to enumerate at high speed (480Mb/s). Some BIoSs can not handle a keyboard that negotiates at higher than low
speeds, so the keyboard section of the VCo will not work.
