Product Details

What is IBM Z?

The new IBM z15 delivers performance, flexibility, availability, protection, and agility to drive digital transformation. It has changed the footprint of IBM Z with a 19” frame, that scales from one to four frames depending on the configuration, enabling significant floor space reduction.

IBM z15 has the commercial data privacy and security enforcement solution, Data Privacy Passports, that provides off-platform access revocation. Choose who accesses data, and when and at what level to revoke their access. One hundred percent of data, at-rest and in-flight, is protected with no performance trade off or application changes. With Fibre Channel Endpoint Security working with the latest DS8900F, achieve total end-to-end protection and authentication.

IBM z15 provides flexibility, portability and choice for hybrid cloud deployment. Cloud-native development simplifies life for developers as they build new applications and modernize existing ones. IBM Z supports private and public cloud via Linux, Kubernetes and industry-standard tools. With the Red Hat OpenShift support, IBM z15 adds to the user's options for cloud integration.

Instant recovery reduces the impact of planned and unplanned downtime. All systems need downtime for maintenance, and security patching.
