But today, does an IBM mainframe use a bus that is faster than
PCI-Express ?

In terms of disks, wouldn't mainframes and commodity servers use the
same type of disk array interfaces ?

Or is this a case of modern mainframes using the same types of
interfaces, but surporting multiple instances whereas comodity servers
only have one PCI-Express and one interface card to FC or whatever type
of interface to a disk array ?
