A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

A

AI Inference Partition ... A separate supported operating-system partition used to execute an AI model while an IBM i partition may remain the production application and data source.
AI Workload Placement ... The decision about which system, operating environment, and partition executes an AI model or agent, separately from the IBM i application supplying its data.
AS/400 ... IBM's original 1988 midrange business computer platform; the term is still used informally to refer to IBM i systems and shops even though IBM has rebranded the hardware and OS multiple times since.

D

Db2 for i ... The relational database management system built into every IBM i operating system, tightly integrated with IBM i rather than a separately installed database product.

E

ENZ0 Expansion Drawer ... The PCIe4 expansion drawer IBM documents for supported Spyre Accelerator for Power configurations on Power 11 systems.

I

IBM i ... IBM's operating system for Power servers running traditional AS/400-lineage business applications, with Db2 for i built directly into the OS.

M

Matrix Math Acceleration (MMA) ... An on-chip acceleration feature in IBM Power10 and Power11 processors that speeds up the matrix math operations used in AI inferencing, without requiring a separate GPU.
