they still push z/OS (the descendent of OS/370) as a primary mainframe 
OS for large scale database and batch processing, and AIX on Power 
servers for big database servers and such.    Linux still has vertical 
scaling issues for larger workloads, and transaction processing doesn't 
scale well horizontally without massive complications.

System/38 long ago (late 1980s) gave way to AS/400 which is now IBM i 
(aka i5/OS), and runs on the same Power servers as AIX, either 
virtualized or whole-iron.   RS/6000 long ago was renamed pSeries or 
Power, and is hardware, which runs AIX, i, and Linux.

but, i don't believe CentOS runs on Z (descendent of System/370) or 
Power (also known as PowerPC) architectures, so this is all off topic.
