IBM z/VM 7.4 provides clients with a premier hypervisor for their existing workloads while also providing support for a modernization journey to hybrid cloud, hosting enterprise-class virtual servers to exploit the advantages of IBM Z and IBM LinuxONE in scalability, performance, high availability, and security.

IBM z/VM 7.4 provides:

• Timely, client-driven functions, previously delivered in the service stream of z/VM 7.3. New functions delivered with z/VM 7.3 positions z/VM 7.4 with improved:
  • Consumability. Through the performance data pump.
  • Performance. With reduced large guest logoff time.
  • Scalability. Supporting 2 TB guest virtual memory, 8-member single system image (SSI), and improved CPU handling.
  • Resilience and usability. Provided by numerous enhancements for z/VM system programmers.
  • Security. With guest secure IPL, a new compliance interface, and digital signature verification of service.
  For a detailed description of function delivered in the z/VM 7.3 service stream, see the z/VM Continuous Delivery News web page.
• A new strategy for applying z/VM service in a linear fashion is designed to be a simpler approach that reduces the complexity of servicing z/VM systems. In a linear service model, applying a PTF causes all previous service for the same component to be included, helping avoid rediscoveries of previously corrected problems.
• A new Architecture Level Set (ALS) that requires one of the following IBM Z and IBM LinuxONE servers or later:
  • IBM z15 Models T01 and T02
  • IBM LinuxONE III Models LT1 and LT2

Product information, including system requirements, tech notes, support, and more, will be available on or before general availability in IBM Documentation.
