IBM has announced the new z14 ZR1 / LinuxONE Rockhopper II on April 10, 2018. The key new feature for me of this box is the form factor. Instead of the decades old 24″ rack a standard 19″ rack is being used. So this box now fits into standard data centers. No special place needed. Besides being the “small” Z box, nothing changed from a hardware perspective. So most of the general topics from z14 do apply.
