Compute Unit of Measure

|---|---|---|

Windows Linux Unix |
Physical Servers | Include standalone physical servers and hypervisors (that are hosting VMs). Count each server as 1. Do not count virtual machines hosted on hypervisors. Include Disaster Recovery volumes. |

Windows Linux Unix |
Logical Servers |
An operating system image, partition or virtual server hosted on a physical server. OS Instances may be implemented using partitioning firmware (as provided on large Unix servers from Sun and IBM), or through third party utilities such as VMware or Microsoft. The term “VM” (Virtual Machine) has become common parlance for an “OS Instance” except that a physical machine with no VMs still counts as one OS Instance. Do not count firmware, stub operating systems, the ESX host or virtualizing software as a separate OS Instance. Include Disaster Recovery volumes E.g., a hypervisor with 50 virtual machines would be counted as 50 OS Instances. Do not count the physical host hypervisor as a separate OS instance. |
| Mainframe | Total Configured MIPs | MIPS is defined as: Millions of Instructions per Second. Include total installed MIPs, not just average used MIPS. Include Disaster Recovery volumes. |
