options are to ignore sound, or to redirect sound to the I/Port. This last option
provides the highest quality experience but also requires additional bandwidth.
If the user has limited bandwidth and does not require sound, this option can be
turned off.
NOTE: RDP only supports audio out (i.e., from the blade to the I/Port) so speakers
connected to an I/Port can play sound generated by the PC blade. However,
audio in (i.e., from the I/Port to the blade) isn't supported by RDP so audio
devices such as microphones cannot transmit back to the PC blade.
•
Local Resources: Devices – RDP allows local disk drives, printers, and serial
ports to be redirected. Again, these require additional bandwidth. Large quantities
of writes and reads from local disks can adversely impact the performance of the
RDP session.
If the user does not require printers or serial ports, it is best to disable re-direction
to prevent any potential bandwidth loss caused by the blade OS carrying out any
sort of detection or other processes for these devices.
•
Experience – Selecting a connection speed causes specific items listed in the
connection speed pull-down menu to become checked or unchecked. Generally,
the desktop background, especially if it is an image, is a significant source of
performance slowdowns. The reason is that every time a window is moved within
an RDP session, new parts of the background get exposed and need to be
re-transmitted. This is generally a slow and time-consuming process. It is preferred,
almost under any bandwidth conditions, to not use a picture background.
