Processor considerations for z/VM mode LPs

Edit online

You can define a logical partition to use one or more zIIPs, IFLs, and ICFs with z/VM® 6.4 or higher with either of the following combinations:

  • One or more dedicated general-purpose CPs and one or more dedicated zIIPs/IFLs/ICFs.
  • One or more shared general-purpose CPs and one or more shared zIIPs/IFLs/ICFs.

The partition mode must be set to z/VM in order to allow zIIPs, IFLs, and ICFs to be included in the partition definition.

In a z/VM mode partition, z/VM will:

  • Operate z/TPF and z/OS® guests on CPs.
  • Operate Linux® on system guests on IFLs and optionally on CPs.
  • Offload z/OS guest system software process requirements, such as DB2® workloads, on zIIPs, and optionally on CPs.
  • Provide an economical Java execution environment for z/OS guests on zIIPs and optionally on CPs.
  • Operate coupling facility virtual machines in support of a Parallel Sysplex® test environment on ICFs and optionally on CPs.

For additional information about using these capabilities of z/VM, refer to z/VM Running Guest Operating Systems, SC24-6115.
