Test configurations

Edit online

A variety of distinct z/VM configurations were used for the tests. Each z/VM configuration is characterized by a unique combination of the amount of z/VM real memory, the amount of z/VM real processors, the type of paging device, and the z/VM release level.

In order to reduce textual replications within this document, configurations were assigned configuration IDs (CIDs), according to the following identification scheme:

<CID> = <ZVMmem>/<ZVMcpu>

where:

<ZVMmem>: is the amount of real memory configured for z/VM, in GiB
<ZVMcpu>: is the number of real processors configured for z/VM

For example, if z/VM was configured with 128 GiB of real memory and with 15 real CPUs, then the CID would be: 128/15.

Table 1 lists the CIDs for various z/VM CPU and z/VM memory configurations.
