Why IBM z14

Select the model ideal for your business or data center

The IBM® z14™ family of servers is now available in two form factors. Our dual frame model provides unprecedented performance while our new single frame model delivers z14 capabilities in a 19-inch industry standard frame with a lower entry cost. The new model's flexible, space efficient design offers 10 percent more capacity while occupying 40 percent less space than z13s – making it ideal for the cloud data center.

Encrypt all application data at rest and in flight

Simplify compliance and protect your critical data from internal and external threats – at low cost, with high performance, and without application changes or SLA impacts. IBM z14 is the only server which can deliver 100 percent encryption of application, cloud service and database data.

Deliver exceptional service – even during peak volumes

Take Black Fridays in stride. IBM z14 delivers more performance so you can deliver quality service – even at peak transaction rates. This server rapidly responds to changes in business demands by reallocating resources automatically based on priorities and by quickly and efficiently deploying new services.

Gain business continuity with a reliable platform

Ensure continuity of operations with availability built in to every element of the system. IBM z14 delivers 99.999 percent application availability and powerful disaster recovery capabilities. Some client installations have run for over a decade without a second of downtime!

Create value through secure application and data innovation

Discover and expose existing code for rapid and efficient new service creation. Optimize resource utilization and simplify management to drive efficiency. Enable flexible deployment of micro-services, increase services reuse, and deliver efficiency through new economic models. And technologies like IBM Secure Service Container help deploy applications in a tamper-proof environment – safe from internal and external threats.

Uncover crucial insights through machine learning

With z14 you can apply machine learning to the valuable data that resides on the mainframe without moving data. It allows you to take advantage of open source machine learning tools and methods. Gain real time insight while avoiding the time, cost, latency and risks of moving data around the enterprise.
