General purpose instance profiles - s390x Gen 2
The IBM Z or LinuxONE general purpose instance profiles (balanced, compute, and memory) are built atop the s390x processor architecture, with native integration into IBM Cloud® VPC. The profiles fit a wide variety of purposes for workloads that
require IBM Z resilience, performance and platform.
The general purpose profiles can also be paired with a corresponding dedicated host. This solution allows for single-tenant hypervisors running workloads from a single IBM Cloud account. For s390x, a dedicated host offering is a dedicated logical
partition running the IBM Cloud hypervisor.

Limits
An instance has a limit for the number of volumes and virtual network interfaces that can be attached. This limit is based on the size of the instance.
