Solaris on the mainframe made big news this week, but we’ve got the straight story from David Boyes, president and chief technologist at Ashburn, Virginia-based engineering firm Sine Nomine.
Solaris on the mainframe is old news. Boyes’ team (which was responsible for bringing Linux to Big Iron) has been working on porting Solaris over for 18 months. Which means it’s that much closer to happening than you might expect — but Boyes won’t say when Solaris on System Z will become available beyond “soon”.
Porting Solaris over to run on z/VM became a possibility when Sun took Solaris open source in 2005. Up to that point, “Solaris was a black box,” Boyes said. Sun has been contributing technical knowledge and hardware, IBM just got on the bandwagon.
According to Boyes, the reasoning the behind moving the Solaris workload over to Big Iron is that Sun customers are sitting on a lot of small to medium-sized pizza box servers. It’s the same problem facing Wintel users — server sprawl.
“How do you address that workload in a way that can take the value of existing infrastructure and deals with the power and cooling issue?” Boyes said. The answer: Big Blue Solaris.
IBM is gung-ho on consolidating Unix workloads onto the mainframe. In a recent announcement, IBM said it would consolidate AIX Unix servers in its own data center, but in this case IBM is switching those AIX workloads over to Linux, not porting AIX to Big Iron.
But the news about IBM consolidating its own AIX machines and the possibility of Solaris on the mainframe got people thinking — Why not AIX on System Z?
Users on the IBM-Main site asked why doesn’t IBM create a special purpose engine, similar to the IFL, for AIX? Wouldn’t AIX running on a System z special purpose engine generate benefits similar to Linux on IFL?
Turns out those are entirely separate questions. Similar benefits? Maybe for end users — but what’s in it for IBM? Not much.
According to sources at Big Blue, IBM has no financial benefit to support an AIX specialty engine on the mainframe. It’d cost too much money to implement, virtualize and port AIX to System z; plus it would compete with AIX on System p, not to mention create another platform on which IBM and other middleware would have to be ported and certified.
Paul Murphy blogging over at Ziff seems to think that IBM will buy HP-UX. Maybe they’ll port that next. Two out of three ain’t bad.
