InfiniBand Host Bus: I am somewhat aware of what this is. What software
supports it? z/VM & Linux only? Or z/OS and z/VSE as well? What about in the
future? From later in the list, is this only for Coupling Facility links?
I'd suggest Redbook about InfiniBand in z10. SG24-7539-00.
In few words Infiniband is used for copupling links only, so only z/OS
(and CFCC) can exploit it. So, no VM, VSE, TPF, no Linux.
In fact there are two flavors of IB in z10: fiber optic - for coupling
links, and copper - STI replacement.
It is also possible to have PSIFB (IB coupling links) in z9, but:
1. Currently only Coupling Facility can use it in z9 CPC
2. To order that feature you have to own z10
3. The speed of PSIFB in z9 is half of z10.
