OpenSolaris on System z - finally goes public
By jsavit on Oct 17, 2008
I've been involved in this too, but I've kept mum till now. I've been in conversation with SNA's David Boyes and Neale Ferguson since 2005 when they started on this, and have been testing since February of this year. I made a few introductions to Sun people, helped arrange the workstation SNA uses for the port, suggested some design choices (64-bit mode only, and leverage the VM hypervisor for ease of implementation).
Next week, I'll be presenting on this subject at the Metropolitan VM User Association (MVMUA), which I used to be President of when I was a customer. I have long roots in this community. I'll be presenting on Sun, Solaris, OpenSolaris and Sun virtualization in general (this group is primarily IBM customers) for background, and then discuss OpenSolaris on z. I'll describe testing and performance (oh yes indeed, I did some performance comparisons between z and other platforms. Heh, heh.) Should make for quite an interesting session.
If you want to run it, you'll need specific hardware: an IBM z9 or z10 mainframe running current z/VM. Sorry, but it won't run under the popular Hercules mainframe emulator. Not yet, at least. When that's available this project will be accessible to a far wider community than the people who happen to have a z.
For a little excitement, this topic has already come up on Slashdot, where you can already see the kind of back and forth Slashdot is known for!
