Installing Db2 Analytics Accelerator on Z

Db2 Analytics Accelerator on Z can be installed with a single processing node or with multiple processing nodes that share the accelerator workload.

About this task

A single-node installation is sufficient in many cases. It requires a single Secure Service Container (SSC) LPAR.

A multi-node installation requires five or six dedicated Secure Service Container (SSC) LPARs, which must be organized in an LPAR group (cluster). A multi-node installation is recommended if your IBM Z® has 30 Integrated Facilities for Linux® (IFLs) or more. Tests have shown that the distribution of large workloads to different LPARs leads to a better performance. It is also a good idea to start with a multi-node setup if you expect your workload to grow considerably.

Attention: A single-node installation cannot be converted to a multi-node installation later, or vice versa. This requires a new installation.
