When did the zEC12 microprocessor come out?

The zEC12 microprocessor (zEnterprise EC12 or just z12) is a chip made by IBM for their zEnterprise EC12 and zEnterprise BC12 mainframe computers, announced on August 28, 2012.

Can a zEC12 be upgraded to a HA1?

Any zEC12 can be upgraded to another zEC12 hardware model. All upgrades to Models H20, H43, H66, and H89 are concurrent and all upgrades to HA1 are disruptive (that is, the system is unavailable during the upgrade). Any z196 or z10 EC model can be upgraded to any zEC12 model, which is also disruptive.

What kind of drivers are needed for a zEC12?

When a z196 is upgraded to a zEC12, the z196 driver level must be at least 93. If a zBX is involved, the driver 93 must be at Bundle 27 or higher. When upgrading a z196 that controls a zBX Model 002 to a zEC12, the zBX is upgraded to a Model 003.

How many instructions can a zEC12 chip decode?

The zEC12 chip can decode three instructions and execute seven operations in a single clock cycle. Attached to each core is a special co-processor accelerator unit; in the previous z CPU there were two shared by all four cores.
