I'm not sure who "Randy" is, but this list has pretty long history of
full disclosure and not suffering any fools. It's interesting that the
three or so posts he has, has to do with N-Computing. If I'm out of
line here, I apologize.
With that in mind I (From Oracle) will give you what I know about
N-Computing as seen through my eyes and and the eye of our customers.
N-Computing offer 3 devices, the "L" (for LAN) the "U" for USB, and the
"X" for PCIx connections.
U and X have 10 meter distance distance limitation. Both require
physical machines to install either the PCIx or USB adaptor cards.
These offer the best USB and Multimedia experience across their product
line (and hey, you can buy them from the Sky Mall catalog).
The "L" claims to have virtually no limitations, how ever real world
usage shows that it consumes 15-20 Mbps on average and requires latency
under 50ms to operate. That rules out "WAN" for most deployments,
unless it's pristine and close.
N-Computing claims up 30 users per "machine" but every example they show
uses 10. Best performance practices I've seen from customers I've
talked to is around 10 as well.
With the L model and their VDI like architectures are done by installing
their vSpace software on VM's. Though it's more of a point and shoot
(i.e. the VM's are always running) vs true brokering and a VDI
lifecycle. This software can be also installed on WTS for multiuser.
All rules surrounding Microsoft Terminal Services Client access licenses
apply, though all their white papers show educational pricing for these.
Non-Edu folks should ask what their prices are.
It's not built to scale out (i.e. you're not going to get the 500 users
bare metal that we are getting on Nehalem boxes), but for smaller
installs it's not bad. There is no Hot Desking, nor the notion of
different personalities per token. Multimedia is indeed good if you are
within their distance and user recommendations. But our multimedia is
pretty darn good now too. Even over 20 hops and 130ms latency.
