This question might be targeted more toward James, but what do people
think about Linux on the Mainframe for deploying Linux? I'm looking
at using zSeries machines to run various databases under Linux, since
mainframes are often acclaimed for their i/o abilities.
Assuming money is no problem, what would be the reasoning behind
going for a normal Linux server setup with fail over compared to
using an underlying operating system such as zOS? What about a Linux
server set up running UML or Xen versus zOS?
Factors that I can think of off hand is that adding more Linux
servers is easier, and software compiled for i386/x86-64 would be far
more common, but for the software I plan to run, a zOS port would
certainly be available. Other things would be the physical labor
involved: that is something that will always be limited. There are
probably more people in the industry that know how to manage Linux
servers than Linux on zOS. zOS is also a "blackbox", so an admin
would have to rely on the vendor instead of training to fix a problem
in some cases.
Any one else have thoughts?
