It is consistent with the behaviour we're seeing:

server 1, 4 core opteron 1.8GHz, 6GiB RAM, doesn't support powersaving
server 2, 4 core opteron 2.8GHz, 8GiB RAM, powernow/ondemand freq governor

In theory server 2 should be much more powerful, as it has more RAM and more
powerful cpu's. But since /proc/cpuinfo shows it's clock freq as 1GHz because of
the powernow cpu throttling, server 1 gets all the sessions, and runs out of RAM
long before server 2 starts breaking sweat. As is mentioned on the sun-rays wiki
somewhere, available RAM should be a much more important factor than CPU. I
would much rather have somewhat slower cpu's and lots of free RAM than fast
cpu's twiddling thumbs while waiting for swap.


 It also considers number of sessions running/idle...
   That concerns me a bit especially since with recent processors,
 increasing speed no longer necessarily means increasing performance.  Can
 the LB algorithm be manually tweaked if necessary?

How about an external command (shell script?) that computes the desirability
of the server in question? (feature request)

Re: [SunRay-Users] Sunray connector and USB support for Win 2008

[William Yang]

I don't think the FabulaTech solution can work on a Sun Ray easily as it is
an ultra-thin client.  The thin clients it is designed to use with are not
as thin; they must run Windows, Linux, or Windows CE on the thin client
device, whereas the Sun Ray runs only a firmware.

Re: [SunRay-Users] Failover group load balancing on servers with lots of cores

[William Yang]

That's an interesting point, I didn't think that CPU throttling was relevant
here, but under Linux at least, that seems to be an issue because LB reads
from /proc/cpuinfo.

I agree that the LB algorithm would seem to need some improving, both the
default automatic algorithm (possibly consider factoring in processor
generation i.e. Pentium 4 vs. Core 2, total RAM, or even current load and
available RAM) and the ability to manually tweak.

[SunRay-Users] HTML5 Video/Audio

[Bryan Gawronski]

Hello,

 

I know that HTML5 is in draft form right now but it includes  new video
and audio tags which will allow for video to be played directly without
the need for a video/audio player (like Flash).  I bring this up only to
voice my support for continued improvement around video/audio on the
SunRay.

 

I know that Sun worked hard to improve Flash content in the latest
version but with so many people and companies turning their backs on
Flash (for example Apple) many web developers are looking for other ways
to stream video/audio.  It appears that most video will be in H.234 when
streamed through the new tags in HTML5.  YouTube is already testing with
the new HTML standard at www.youtube.com/html5.

 

I hope Oracle will continue to look to optimize video/audio solutions on
SunRay as new technology becomes available.

 

You can read more about HTML5 at: 

 

http://dev.w3.org/html5/spec/Overview.html

Thank you for your time.

Re: [SunRay-Users] Sunray connector and USB support for Win 2008

[David Bullock]

True - I wasn't suggesting that Fabula Tech's solution would work directly
on a Sun-Ray - only that it is a reasonable thing to have complete USB
redirection to a virtualised Windows host.

I understand (perhaps I am wrong?) that USB redirection between a Sun Ray
and its Solaris/Linux host is already supported by SRSS out of the box
(assuming a Solaris/Linux driver for the connected hardware exists) - but
that doesn't really help for the 'RDP leg' of the connection to the Windows
host.

Presumably, with the right business arrangements in place, Fabula Tech (or
some other vendor) would be able to leverage their Windows-side experience
with USB redirection in the SRSS/SRWC environment as well ... given that the
Sun Ray firmware already handles USB redirection between the DTU and the Sun
Ray Server.

I thought of one other possibility for Sun's USB redirection story - that is
their proprietary RDP protocol which interfaces to the VM at a machine level
(rather than at the 'Windows session' level).  Maybe that's their strategy?

regards,
David.

support for Windows Server 2008?

I also would like bit of a roadmap for Windows Vista+/7 USB redirection support
(and for completeness, Windows Server OS's too, but that's less pertinent to
me). It's one of the main factors limiting the applicability of Sun Ray
to many situations.

Maybe Sun chose XP because of some of these guesses:

* the largest installed base of VDI VM's are XP;
* Sun had access to existing technology for XP only;
* Microsoft have made it unreasonably difficult to supply USB redirection on
Vista+;
* Microsoft will probably solve USB redirection in RDP sometime anyhow

... I'm just speculating on all of these points, of course.

It would seem that UK-based Fabula Tech have USB redirection for just about
every thin-client out there *except* for Sun Ray [1], working for all versions
of Windows. I exchanged email with Fabula Tech at one stage, and they
were interested in Sun Ray, but seemed to be having trouble coming to grips
with how the SRSS/SRWC/Solaris thing worked together. I encouraged them
to join a Solaris developer program so they could cheaply access the raw
materials, but I guess they didn't successfully engage with Sun on it.
(It was nearly a year ago that this exchange took place). Given that
Fabula Tech have an alleged product that covers all the bases (I've not tested
it or explored its limitations), it seems technically feasible for Sun to develop
(or, now that they're owned by Oracle, acquire) a similar capability.

[SunRay-Users] utconfig libgdbm.so.3 error on RHEL5.3 and SRSS 4.2

[Aaron Wilson]

We originally attempted to install on RHEL5.4 but where told by Sun it
wasn't supported so we installed RHEL5.3 on our servers instead.
Coincidently Red Hat tell us they don't support libgdbm.so.3
They're Sun Fire x4140 servers
Anyways when we run utconfig we get an error. This occurs on RHEL5.3
and RHEL5.4 but in the case it's RHEL5.3 because it's supported

[r...@slosunray01 sbin]# ./utconfig

Re: [SunRay-Users] Sunray connector and USB support for Win 2008

[William BRYSON]

As far as I understand it, what actually happens is this:

 

· The Sun Ray DTU and its corresponding SRSS talk to each other using 
ALP.  

· The USB devices’ connectivity is handled between the 
Solaris/Redhat/Whatever server and the DTU by encapsulating the USB 
communication over ALP.

· The server then performs a local device mapping, using its own USB 
device drivers.

· SRWC/uttsc knows about these server-local devices, and presents the 
ones that were mapped (and that it recognises) via RDP to the windows host

 

At no point does raw USB data go anywhere near the Windows connector or uttsc – 
only devices the SRSS recognises, has drivers for, and that uttsc can present 
over RDP are presented.

 

Certainly it would be nice to be able to present a raw USB device through the 
Windows connector, however as far as I am aware, RDP itself doesn’t support 
this.  There’s likely very good reason for that (something as simple as briefly 
losing the RDP connection could badly corrupt a USB stick if it is being 
accessed via raw USB – it would be like pulling the device mid-write)

 

There is certainly the ability to write (or download/buy) your own customised 
(read: not-vanilla-RDP) remote desktop client that *does* support this, and to 
plug it in as a drop-in replacement for uttsc, but the host you are connecting 
to would have to have a corresponding server-side not-vanilla-RDP service.

 

Anyone that knows SRWC in more depth, please feel free to correct me!

 

Regards,

William Bryson

Yes, but I think it has to do with the firmware implementation of the USB that 
the redirector talks to not supporting all modes of USB operation.  I believe 
those types of devices are not supported with Solaris/Linux and Sun Ray either.

If it skipped Solarsi/Linux, then shouldn't all USB devices that Windows 
supports work from a DTU.  And that is not the case.  There is actually a list 
of supported devices.

Re: [SunRay-Users] utconfig libgdbm.so.3 error on RHEL5.3 and SRSS 4.2

[Aaron Wilson]

I found this old link from SRSS 3.1.1 and RHEL4
http://forums.sun.com/thread.jspa?threadID=5107591

I did the:
 ln -s /usr/lib/libgdbm.so.2 /usr/lib/libgdbm.so.3

I can run utconfig now without the error.
