AIX 7.1

Open, secure, scalable, reliable UNIX operating system for IBM Power Systems servers


Businesses today need to maximize the return on investment (ROI) in information technology. Their IT infrastructure should have the flexibility to quickly adjust to changing business computing requirements and scale to handle ever expanding workloads – without adding complexity. But just providing flexibility and performance isn’t enough; the IT infrastructure also needs to provide rock-solid security and near-continuous availability and while managing energy and cooling costs.

These are just some of the reasons why more and more businesses are choosing the AIX OS running on IBM systems designed with Power Architecture technology. With its proven scalability, advanced virtualization, security and reliability features, the AIX OS is an excellent choice for building an IT infrastructure. Plus, AIX is the only OS that leverages decades of IBM technology innovation designed to provide the highest level of performance and reliability of any UNIX OS.

AIX 7.1 is available in two different editions: The base AIX installation media is the same for both editions: The client specifies the edition to be installed during the installation process. A new command, ‘chedition’ can be used to identify which edition is in use, or can be used to change the edition dynamically without rebooting.

All editions of AIX 7.1 are available on all models in the IBM Power Systems hardware product line. Clients may mix the different editions on a single server.
