Device Management FUD

CLAIM: There is absolutely no difference between updating our thin client software with our client management tools and updating Sun Ray firmware using Sun Ray Server Software.

Linux, Windows CE, and Windows XPE updates vary between 11 MB and 209 MB.  Sun Ray firmware is roughly 500KB - 600 KB depending on whether you use the VPN enabled firmware of not..  Some competitors tout free tools, yet require an enterprise license to manage more than 5 devices.  Not all competitive devices can take advantage of the latest software updates.  Most other solutions require separate servers to run the client management stack.  These separate servers not only require OS licensing, some require database access licenses.  Those are pretty big differences.

Note too that competitor's thin clients have the “capability” of installing “packaged applications” which permit the end user to run additional software components locally on the thin client. This in itself defeats the whole purpose of our competitors “thin clients” as under this banner, they still supply devices that require management on par with most fat clients sold today.

For a fun exercise, read all the release notes of the different operating systems offered by the competition so you can get an idea of the OS matrix that you will have to support and all the different caveats noted for this version and that client.
Comments:

You are so right. I keep hearing that with one competitor you can manage the devices via DHCP and ftp. When I mention that ftp is full of security holes, I get told that well, we'll use this or that secure ftp. If you don't need device management software, then why is that one of the most prominent products advertised on their website? There is a BIG difference between managing a few or even a few hundred devices and managing the thousands that we see in Sun Ray deployments.

Yes, and when I explain that you can should tfp over UDP vs ftp over TCP they claim that it's more reliable so we use ftp. I explained that if you checksum the file after downloading you don't need tcp and hence the download is faster and just as reliable. I got a blank stare ;-)

I actually had someone tell me it was more secure to use TCP instead of UDP. I honestly don't know how these people get the jobs they have.

The funny thing is one security department I talked to would rather us use anonymous ftp vs tftp to grab the firmware. I just had to shake my head.

Nothing I have seen comes close to the ease of use of the firmware upgrade on the SunRays. And with adding the DNS resolver so we no longer need DHCP makes this a perfect solution for home use now.

I've got transport mode IPsec working between Sun Ray
and server. If we really want to do secure firmware downloads, with just a little work we could do TFTP
over IPsec. Would that be good enough?

About the only real downsides to using TFTP are that
it's synchronous and uses small block sizes, and so
the download time is very sensitive to round trip
network latency. That's probably not a huge issue,
since it's an infrequent operation (and there are
TFTP extensions to increase the block size).
