ARM Linux thin client does Citrix, RDP, and VMWare

Jun 23, 2014 — by Eric Brown 4,841 views

Atrust unveiled a “t66” thin client that runs Linux on a quad-core Freescale i.MX6 SoC, and supports Citrix ICA/HDX, RDP, and VMWare Horizon View protocols.

As power consumption grows in priority, the thin client world is increasingly turning to ARM processors. Atrust Computer Corp. offers a number of ARM-based thin clients, and like its x86-based Intel Atom- and Via-based systems, they run a custom Atrust Linux OS. While the company’s previous ARM systems ran on single-core Cortex-A8-based Sitara system-on-chips from Texas Instruments, the Atrust t66 runs on a faster, quad-core, Cortex-A9-based Freescale i.MX6. No clock rate was supplied for the t66, but the i.MX6 typically runs at 1.2GHz, and offers 2D, 3D, and video coprocessors.

Atrust has yet to publish detailed specs on the t66, but it posted a few details. The fanless system appears similar to the earlier TI Sitara based t60 system (see below), measuring 135 x 93 x 29mm and weighing approximately 278 grams, says the company. The t66 is equipped with a DVI-I port, supporting up to 1920 x 1200 resolution, as well as four USB ports.

Presumably, the t66 also supplies a gigabit Ethernet port, some audio I/O, and Kensington lock slots like Atrust’s other thin clients. The device lies flat on the desktop and looks much like the t60 (below). Several mounting options are available, including monitor mounting.


The Atrust t66 is managed by an Atrust device management tool (ADM), and is optimized for Citrix ICA/HDX, Microsoft RDP with RemoteFX, and VMware Horizon View environments. Like other Atrust t-series thin clients, the t66 integrates Atrust Client Setup (ACS) software, providing a local client management console. There’s also an Atrust Device Manager (ADM) that lets IT staff set up a single profile and apply it to multiple thin clients, says Atrust. All data is said to be securely stored on servers.

Here’s a glimpse of the Atrust’s other Linux-ready thin clients, with links to product pages. We start with the ARM-based t6x Series, which similarly runs ICA/HDX, RDP, and VMWare:

  • t63 — The t63 is equipped with a 1GHz TI Sitara DM8168 SoC backed up with 1GB SDRAM and 512MB flash memory. Measuring 143 x 103 x 39.5mm and weighing 380 grams, the fanless device supports Power-over-Ethernet and provides both DVI-D and DVI-I ports for dual 1920 x 1080-pixel displays.
  • t62 — The t62 offers the same dimensions and weight as the t62 and similarly integrates a 1GHz TI SoC, although the type is unspecified. It otherwise appears to be identical except for the lack of PoE.
  • T60 — The t60 looks similar to the new t66, and is smaller than the t66 or t62. It measures 135 x 93 x 29mm and weighs 276 grams. Like the t62, it runs on an unspecified 1GHz TI SoC. Other specs are also similar, but it offers a single VGA port instead of dual DVI ports.
  • t50 — The t50 appears to be an older model, and supports only RDP with RemoteFX. The 120 x 80 x 26mm desktop/VESA mount device has a 1GHz TI SoC, 256MB each of RAM and flash, and VGA output. The t50 provides four USB ports, audio I/O, and Kensington, but the Ethernet is limited to 10/100Mbps.
  • mt100 — This mobile, laptop-style thin client features a 14-inch, 1366 x 768 screen, a 1GHz TI processor, 2GB of RAM, and 4GB flash. Additional I/O includes a gigabit Ethernet port, WiFi, three USB ports, a VGA port, and audio I/O. The mt100 supports Citrix ICA/HDX, Microsoft RDP, and VMWare View.

  • a100T — This all-in-one (AiO) thin client is equipped with a 1GHz DM8148 with 1GB RAM and 4GB flash. The built-in 21.5-inch display offers 1920 x 1080-pixel resolution. Other features include a gigabit Ethernet port, four USB ports, audio I/O, and support for the aforementioned Citrix, Microsoft, and VMWare environments.
  • t200 Series — This Intel Atom N270-based mini-tower offers 512MB each of RAM and flash, as well as gigabit Ethernet. You get both VGA and DVI-D ports, with up to HD resolution. Other I/O includes five USB ports, a serial port, audio ports, Kensington, and an optional smart card reader. There’s also a zero-client T200LZ model without flash memory, requiring remote OS loading and boot-up. A T200LQ model boosts RAM to 1GB, tosses in an S3 2300E GPU, and adds dual DVI-I ports, for four display ports overall. Protocol support for all three models includes Microsoft RDP, X-Access (XDMCP), SSH, Telnet, Citrix ICA, and VMWare PCoIP.

  • t210L — This mini-tower looks similar to the Atom-based T200 and has the same protocol support, but is equipped with a 1GHz Via Nano U3500 processor with 512MB each of RAM and flash. The extensive I/O includes four USB ports, four serial ports, an LTP port, audio I/O, Kensington, and an optional smart card reader. The t210L has PoE-ready gigabit Ethernet and a DVI-I port that supports up to 1920 x 1200 resolution.
  • t100 Series — The t100L is a desktop system with multiple mounting options, offering a 1GHz Via Eden chip, 512MB each of RAM and flash, and an RGB port. The fanless system has four USB 2.0 ports, audio I/O, Fast Ethernet, and support for Microsoft RDP, X-Access (XDMCP), SSH, Telnet, Citrix ICA, VMWare PCoIP protocols. There’s also an almost identical T100LZ zero-client model.
  • t160 — Physically similar to the t100, the t160L and zero-client T160LZ advance to a faster, 1GHz Via Nano U3500 processor. I/O and protocol support is similar, but the device advances to gigabit Ethernet and DVI-I.
