What is the transfer rate of USB devices attached to a Tera2 Zero Client?

Question

I have Wyse P25 and P45 zero client (base on tera2 chip) connected to a Vmware horizon 6 system and when I test Usb transfert rate from and external USB drive, I found out that the maximum transfert rate is about 3 MB/s (Windows and network indications).

I can't find any document that confirm that is the actual maximum speed to expect or if I have a configuration issue somewhere.

The only information I found is about tera1 chip (https://techsupport.teradici.com/ics/support/kbanswer.asp?deptID=15164&task=knowledge?ionID=262)

For comparaison, the same test, but using PcoiP software client instead of Zero client device, show a maximum transfert rate of 10MB/s

Any info ?

Hello Gregory Rouxel,

The maximum USB transfer rates that can be achieved with Tera2 zero clients is up to 3MB/s (Mega Bytes per second). This is on LAN with no latency and no bandwidth restrictions.

Virtual Desktop Host Tera2 Zero Client

Firmware USB Transfer Rate

VMware View 4.6 Agent or newer 4.0.3 or newer Up to 25 Mbps (Mbit/s) per device

Tera2 PCoIP Host Card 4.0.3 or newer Up to 25 Mbps per USB device

Thanks

Hello Gregory Rouxel,

We have internal KB#1253 about USB transfer rates on Tera2 devices. The one which you found (KB#262) for Tera1 devices is public.

Thanks
