its a “virtualized” guest so I/O performance will be less than native
zLinux performance. I haven’t seen any good data on the actual
differences in performance but that would be interesting.
Linux on Z typically runs under z/VM which virtualizes guests using an
extremely high-performing IBM Z hardware virtualization feature called
START INTERPRETIVE EXECUTION (or SIE). This hardware feature results
in extremely low (but of course not zero) performance degradation when
compared to native LPAR.
zCX virtualizes its embedded Linux for Z instance using SIE as well...
I'm curious about how I/O is virtualized? If I install ELK into a zCX
container will it use a zFS file system for the Elastic data base?
