Remote Console; Performance - Intel S2600WF Technical Product Specification

Intel® Server Board S2600WF Product Family Technical Product Specification
• The mounted device shows up in the BIOS boot order and it is possible to change the BIOS boot or-
der 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 appear as floppy disks over media redirection. This allows for the installation of device
drivers during OS installation.
If either a virtual IDE or virtual floppy device is remotely attached during system boot, both the virtual IDE
and virtual floppy are presented as bootable devices. It is not possible to present only a single-mounted
device type to the system BIOS.
8.3.2.1 Availability
The default inactivity timeout is 30 minutes and is not user-configurable. Media redirection sessions persist
across system reset but not across an AC power loss or BMC reset.
8.3.3

Remote Console

The remote console is the redirected screen, keyboard, and mouse of the remote host system. To use the
remote console window of the managed host system, the browser must include a Java* Runtime
Environment (JRE) plug-in. If the browser has no Java support, such as with a small handheld device, the
user can maintain the remote host system using the administration forms displayed by the browser.
The remote console window is a Java applet that establishes TCP connections to the BMC. The protocol that
is run over these connections is a unique KVM protocol and not HTTP or HTTPS. This protocol uses ports
#7578 for KVM, #5120 for CD-ROM media redirection, and #5123 for floppy and USB media redirection.
When encryption is enabled, the protocol uses ports #7582 for KVM, #5124 for CD-ROM media redirection,
and #5127 for floppy and USB media redirection. The local network environment must permit these
connections to be made; that is the firewall and, in case of a private internal network, the Network Address
Translation (NAT) settings have to be configured accordingly.
For additional information, reference the Intel® Remote Management Module 4 and Integrated BMC Web
Console User Guide.

Performance

The remote display accurately represents the local display. The feature adapts to changes in the video
resolution of the local display and continues to work smoothly when the system transitions from graphics to
text or vice-versa. The responsiveness may be slightly delayed depending on the bandwidth and latency of
the network.
Enabling KVM and/or media encryption does degrade performance. Enabling video compression provides
the fastest response while disabling compression provides better video quality. For the best possible KVM
performance, a 2 Mbps link or higher is recommended. The redirection of KVM over IP is performed in
parallel with the local KVM without affecting the local KVM operation.
