Why would you not want a SunRay?

The answer is: "if you want 3D graphics".
If like me you don't need this day to day, then SunRay is just a winner. Given this I am constantly suprised by how much like using a SunRay is like owning a Mac. Everyone who does not use one will tell you how there is no way they will work for them, and all those using them think they are great. True they are only as good as the server that drives them but given that âhalfâ the server that is driving ours has 4 cpus, each with 2 cores and loads, memory, Gigabit Ethernet and runs the latest build of S10 and the other âhalfâ is in f act 2/3rds that is very good indeed. Not many non SunRay users get that for a desktop.
Each time I remove the card from the SunRay and walk to another location, insert it, and my desktop is just there I see the benefit. Walking into the lab, going into an office for a con call, showing a colleague a problem, all are a winner. And Xinerama works flawlessly with the twin headed one, even wen you then move to a single headed SunRay in the lab.
Yet still people who don't use SunRay say they won't work for them. Odd. For driver development I use a lab system, which I access via ssh(1) or via the console server we have. For running a strange window system, I use, SunRay (remote login can be done), for crash dump analysis the SunRay server has lots of memory and is great, resource management keeps it going for other users.
Often it is because people use their desktop to reproduce problems, but SunRay does not prevent that behaviour though it can be painful when you reproduce the hard hang on your desktop, much better to use a lab system to reproduce the problem and SunRay to manage your display, allowing you to keep working, and then move to the lab to stare at the blinking (or not) lights when the time comes and still take your desktop with you.
O.k. Some engineers just have to have the root password to to âtheirâ system I achieve all that I need in that area by using a zone on the SunRay server which I use dtlogin to access remotely. I can do all the fiddling I feel I must, which is more than most people, in the safety of my zone while the rest of the group are either in their owns zones or in the global zone. Unbundled software can be installed, I can have DNS as my prime name service for hosts, IPv6 can be running and I can reboot just like when I had a workstation, but my âworkstationâ now has 4 cpus and 8 cores, loads of memory, Gigabit Ethernet and mirrored disks that I don't have to worry about.
True you can fake most of the SunRay functionality up using VNC and x11vnc, but when you do this you have to be sure to secure the keyboard of your desktop, and while good VNC and x11vnc are not a easy to use and do not perform as well. Indeed I do this with the SunRay to allow me to grab my session from home or from my laptop, but securing the keyboard with SunRay is as easy as removing your SunRay card, or if not using a card typing âutdetachâ.
Would I have âmyâ workstation back?
Only if it could be configured as a SunRay server.
What would I like to have next?
My zone to be configured as a SunRay server.
So the question remains: Why would you not want a SunRay?
