Error description
The 4 TB real memory support allows the definition and use of real memory up to the 4 TB line for first-level z/VM systems, doubling the previously supported 2TB limit for z/VM 7.2. VM66173 also allows overcommitment of total virtual memory across all guests beyond the 4 TB line, depending on workload characteristics. The additional real memory support along with support for 80 processors allows additional workloads to be consolidated on one z/VM LPAR running on IBM Z and LinuxONE servers.

Problem summary
**************************************************************** * USERS AFFECTED: All users of z/VM that wish to run in a * * partition with greater than 2TB and up to * * 4TB of real memory. * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** With the PTF for APAR VM66173, z/VM 7.2 provides 4 TB real memory support, an enhancement to the CP DEFINE STORAGE command, and various other command updates. The 4 TB real memory support allows the definition and use of real memory up to the 4 TB line for first-level z/VM systems. Overcommitment of total virtual memory across all guests beyond the 4 TB level is supported. The per-guest limit of 1 TB of virtual memory remains unchanged. With automatic standby memory for guests, a system administrator can code a more generic DEFINE STORAGE command that does not need to be updated every time the guest's directory entry storage size changes. See https://www.vm.ibm.com/perf/reports/zvm/html/ for details of the performance scaling with the increase in supported real memory.
