Think of vRDP like capturing the output of a video card of the console.
It's not built for multiple people on the same machine (though it does
a method that you can have multiple "video cards", but that's just
mirroring what's coming from the single console.
While we do have MS-RDP7 enhancements, due to the native of using the
native Microsoft experience features (unlike 2003 were we wrote
solutions that were limited to flash through IE and certain types of
content through WMP) the Sun Ray Server has to be more powerful. Which
is why I recommend trying your current setup but using a fast x86 server
at the Sun Ray server instead of the CMT servers, that can be very fasts
if applications are written to take advantage of the archtictures (i.e.
multithreaded aps operating in parallel)
However vRDP has other features that either MS-RDP doesn't have or
actually blocks from working. For instance, DRM protected content won't
play over MS-RDP, but with vRDP, the software doesn't have any idea that
you are coming in remotely so things like the netflix player would even
work.

Craig,
Does the fact that vRDP attaches at the Hypervisor level make it less useful
or even non-functional in a WTS scenario? Or does it perhaps mean that there
will be resource constraints since it's not multi-user?
It was my understanding that of the 2 performance tweaks [going to x86 and
VirtualBox], vRDP was supposed to provide the lion's share of the performance
boost. Has that been your experience?
For scenario 1, did SRS 5.1.2 markedly improve SRWC, which is where I would
imagine the action to be happening?
We are currently pursuing scenario #2 but I suppose, along the way, we can also
do #1.
Thanks as always for your detailed information.

vRDP attaches at the Hypervisor level, it's not multi user like WTS/RDS
The two things that I've suggested trying for your app are:
1) Use a modern x86 server (rather than CMT) and see how your app works
with SRS 5.1.2 and our MS-RDP7 enhancements. Currently the CMT server
in your mix is affecting how well our new RDP7 feature works since we
have to convert the Microsoft enhanced bitmap stream to M-JPEG at the
Sun Ray Sever layer.
2) Build a VirutalBox VM of Win7 (or 2008R2 if that's easier) and see
how your app works over vRDP. Little if any processing takes place on
the Sun Ray server.

Craig,
Does your statement imply that, since there is only one console display,
that only 1 user would be able to use that W2K8/R2 WTS? Or can I somehow still
manage to put many users on the WTS and they can all take advantage of the
accelerated video?
Thanks.

The catch is that for 2008R2 is access by a vRPD would be akin to you
being on the console. Technically 2008R2 is RDP 6.1 with enhancements
that are only available to RDP 7 capable clients.

If I understand it correctly, I can still use a W2K8/R2 VM as the guest within
VirtualBox and reap the benefit of video redirection. What tripped me up is
the following line in the documentation:
7.1.9 VRDP video redirection
[...stuff deleted]
On the client side, however, currently only the Windows 7 Remote Desktop
Connection client supports this feature.
Wouldn't it be more accurate to write "RDP 7" instead of "Windows 7"? Because
W2K8/R2 uses RDP 7 but is not Windows 7, technically.

Hi Ivar,
Not all the pieces are in place to make that suggestion work seamlessly
today, but I believe Oracle understands the benefit of such a solution
and the value of having it work seamlessly with it's desktop
virtualization offerings.
I have to say that it warms my heart to see members of the community
realizing the potential of VirtualBox brings to the VDI market. ;)
Over the past couple of years, the product teams for Oracle VDI and
VirtualBox have developed an amazing symbiotic relationship. Of course
this is just my opinion, but I seriously doubt our any of our prior VDI
efforts were really considered Sun acquired InnoTek. Nor do I think
anyone ever really envisioned that the Sun Ray product group would
become the primary consumer of VirtualBox technology. I know there are
plenty of stories of people who left Oracle because they didn't like the
decision made about the products they worked on, but I can't say I share
that sentiment. It's a pretty exciting time to be involved with both
Oracle VDI and Sun Ray.

Although I have not tested it. A theoretical solution would be possible

If you run a VirtualBox server with Windows XP/7 then you can enable 3D
hardware acceleration in de VM and VirtualBox additions software in
Windows.
If you connect from the Sun Ray server to the VirtualBox server with
VRDP then you can use de Rapid Changing Area (RCA) detection feature in
VRDP to get the 2D image compressed and sent to the Sun Ray.
I think this is the best route to go.
Kind regards,
Ivar

Hi there,
we are having a similar sort of problem, there is a product called
virtual gl which has the exact solution to this problem. however the
catch is that sun discontinued its support in 2009 (thereby the plugin
which integrates a virtual gl server to sunray is now in-existent on
the internet). I have tried contacting the developer incharge of it on
source forge but the guy didnt reply. I hope someone else has a better
or at least an acceptable solution to this problem.
Regards
