Minimum System Requirements
Host PC
Refer to the
in the NComputing Knowledge Base for the
latest information on supported operating system versions (note that unless specifically listed in
the OS support matrix document, a new OS service pack may not be supported by then-current
vSpace software). For more information regarding Microsoft licensing, please see the Important
Notices section at the beginning of this document.
Almost any modern PC can be used to host NComputing vSpace software. The guidelines
below are a good rule of thumb for determining how many users you can provision on a host PC
and expect to have a native experience running general productivity software applications.

The table below describes the maximum bandwidth of the USB bus for modern PC
motherboards. Some PCs may contain multiple Enhanced Host Controller Interface (EHCI)
controllers that can double or triple the available bandwidth. These systems will have better
video performance when running more than four U170 devices on a host PC. To take
advantage of multiple controllers, connect any downstream hubs back to the host PC directly
rather than connecting all U170s downstream of one USB connection. Installing an additional
USB controller card in the host PC is also an option for large deployments.

These are general guidelines. Always test your applications first before deploying.
2
When installed on Windows XP, only five U170 devices can be supported. See
for specific use cases.
3
Deployments with more than four users require dual Enhanced USB controllers.
4
For 64-bit operating systems, 6+ GB of memory recommended.
Note: The U170 requires USB 2.0 controller(s) for operation. In addition, some
older PCs may have difficulty booting with U170 devices (or other high-speed
USB audio devices) attached. In these cases, you may need to boot the host
PC first, and then attach the USB cable. This problem can sometimes be
resolved by installing a separate USB 2.0 PCI card into the host PC.
