PureSystems is an IBM product line of factory pre-configured components and servers also being referred to as an "Expert Integrated System".

PureSystems can host four different operating systems (AIX, IBM i, Linux, Windows) and five hypervisors (Hyper-V, KVM, PowerVM, VMware, Xen)[2] on two different instruction set architectures: Power ISA and x86.

PureSystems is marketed as a converged system, which packages multiple information technology components into a single product.

These "Patterns of Expertise" offer industry-specific (e.g. banking, insurance, automotive) defaults for the fully automatic and optimal orchestration of resources (e.g. workload balancing).

A flex-chassis can accommodate up to 14 horizontal compute and storage nodes in the front, and 4 vertically oriented switch modules in the rear.

PureData is focused at three main tasks within enterprise computing: business intelligence, near real-time data analysis and online transactional processing.

It is aimed at e-commerce (i.e. retail and credit card processing environments) which depends on rapid handling of transactions and interactions.

PureData System for Analytics builds on Netezza technology and it is aimed at business intelligence that entails huge queries with complex algorithms.

It provides a large library of database analytical functions for data warehouse applications, and can scale across the terabyte or petabytes running on the system.

Potential uses of PureData Systems for Operational Analytics are fraud detection or analysis of rapid fluctuations in supply-and-demand cycles.
