The following is a summary of the z/VM 7.4 announcement. For more information, please reference the full z/VM 7.4 announcement.


IBM z/VM 7.4 delivers capabilities to help improve the service experience

Overview

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.

Virtualization is fundamental to delivering infrastructure as a service (IaaS). IBM continues to invest in z/VM technology to provide leading-edge virtualization capabilities, helping to meet the needs of IT organizations by delivering a foundation for user satisfaction with various types of workloads, including:

  • Cloud-native workloads based on the Red Hat OpenShift Container Platform and IBM Cloud Paks or other container technologies.
  • Non-containerized workloads deployed using cloud and traditional operations models, available from IBM programs, such as IBM WebSphere, open source such as MongoDB, or independent software vendors (ISVs).

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.
