Ncomputing Xd3 Access Device (2025)

  • Network: Use dedicated VLAN for thin clients, prioritize UDP traffic (port 3898 for vSpace).
  • Enable hardware acceleration in vSpace Policy:
    Multimedia Redirection → Force hardware decoding.
  • Disable desktop backgrounds and animations on the virtual desktop to reduce bandwidth.

    • Unlike a standard PC, the XD3 has no CPU, hard drive, or RAM. It functions strictly as an input/output terminal.

  • Needs: No local OS – it downloads a small operating system from the vSpace Server or uses embedded Linux.

    • Here is where the XD3 distinguishes itself. In standard VDI, when you scan a document at 600dpi, that raw data travels from the scanner → thin client → network → server → back to thin client. This consumes massive bandwidth and CPU cycles on the host. ncomputing xd3 access device

    The XD3 includes Local USB Processing. The device handles the low-level USB control transfers and bulk data processing on the device itself, compressing the data before sending it to the virtual desktop. For a finance department using USB smartcard readers or a medical office connecting ECG monitors, this means zero perceptible lag. Network : Use dedicated VLAN for thin clients,
