What he said is true for z/OS systems. RHEL and SLES are pretty much the same on a z10 as an x86.
I have found a few things I could not do:
Support custom hardware (no slots on the z box)
What hardware?
Assuming we mean *servers*, not workstations - we can forget about
graphic cards, scanners, USB sticks, mouses, etc. When talking about
network & storage - well you can use only Ethernet (is it constraint
nowadays?) and vast majority of SCSI/FC devices.
Share memory between two or more Linux images (LPAR or z/VM)
I don't think it is possible between x86 boxes ;-)))
Promote binaries from z to x86.
The same apply when promoting from IA64 to x86, or sometimes from AMD to
Intel, or POWER to x64, or...
Indeed, the most compatible with x86 is ...another x86. But - is it good
criterion?
OK, x86 is the most popular platform for Linux, so maybe there are tools
available for this platform only. Many moons ago I was administering Win
NT 3.51 on Alpha AXP - availability of tools and toys on this platform
was real pain.
