Bandwidth requirement of the Teradici HW Zeros

I was planning a View infrastructure based on HW Teradici clients, over WAN.

I found this document about the HW Tera clients, which is for PCoIP host cards and zeros, but it applies for zeros and View 4.6 too. The facts:

• The minimum bandwidth for a Teradici based Zero (see previous post and list of devices) is about 1 Mbps. This is the "bandwidth floor" in the firmware settings. Using a Cisco 6500 we limited the effective bandwidth in Layer 2 for the device (Samsung NC190 and NC240, tested separately). We found out, that the client becomes "sluggish" at about 512 Kbps, and the whole session is unusable/unstable below 256 Kbps. This is not a limitation of PCoIP, because it is known to work at about 150 Kbps. It's probably a limitation of the TERA1x00 chip.
• The maximum bandwidth usage as stated in the document above, is 220 Mbps. I can hardly believe that the device can use this much, but who knows. Watching HD video/audio on a dual 24" screen setup, while scanning and copying files over USB probably peaks way above 100 Mbps. The 220 Mpbs theoretical maximum is probably counted with 4 24" monitors daisy chained over 1 Tera chip, with HD audio and video streams and heavy USB usage.
• The average usage that we observed while clicking MS word and such on the 24" (resolution counts bandwidth of course) was about 6-7 Mbps with a minimum usage just above 1 Mbps and maximum peaks at about 13.

Conclusion? The HW Tera devices are not fitted for low bandwidth situations, while they are probably the best technology if You happen to have enough bandwidth/device.

I will try out PCoIP software clients (Windows & HP's Linux one :)) in the near future with the same bandwidths.
