Sun Ray, Green Screen and VNC

I have a client that is exploring thin client technologies. They want to update their desktop technology. But they do not have the resources to rewrite their existing client. An existing Green Screen client that runs perfectly in a terminal window. Except the terminal clients on RHEL block certain function keys. Certain keys are intercepted by the terminal application for menu operations and are not passed to the green screen client.

I had an light bulb idea. Why not use VNC to connect to the client to see how well that would work. It works like a charm. All the function keys get sent through. One exception was the F8 key. Luckily VNC will let you remap that key to some other combination.

So now we have a solution that protects the customers investment while letting them move to current display technology.

Atom powered Sun Ray Server

Some times you do crazy things in life. I had the opportunity to purchase a Intel Atom 330 powered nettop computer for $140.00. Since I already had a spare sata drive and dvd drive the cost was attractive. The box has 2 cores with hyper-threading enabled. It speeds along at 1.6 ghz. Yep it is a barn burner with all fours threads showing up as 4 "cpus".

So now the question was what can this baby do. I have a customer Sun Ray gig next week. So I decided to replicate the install process. Surely not the hardware. So the little atom is running RHEL 5.3, Sun Ray Server 4.1 and the Sun Ray Windows Connector. It is like the Prius of the Sun Ray servers out there. It is handling a couple of desktops. Only using 828 mb of the 2GB of maximum ram the box will take. Yet it is only using 65 watts of power.

To be sure, I will not be transcoding video with this baby. But for a lightweight environment with a handful of users the Atom is doing quite well. Granted the Atom is not going to handle a 700 user call center alone but it makes you think.
