Stream: zP&C
Time: 16:30 - 17:30
With its introduction of virtual cache at levels 2, 3, and 4, the z16 represents the most significant change to the z processor architecture since the z13. The magnitude of these changes has understandably generated a great deal of curiosity into how this virtual cache approach operates conceptually and how it is actually performing at customer sites. The two speakers in this session will tackle both of those topics: (a) John will highlight all the key z16 advances with particular focus on the new cache architecture, explaining the concepts so you can optimize your configuration. (b) Todd will present findings from numerous customer upgrades quantifying the extent to which z16s are delivering on their rated capacity.
