Hardware Reference Data
Introduction
BMC Discovery provides Hardware Reference Data (HRD) for hosts, host containers and hardware containers. Such Hardware Reference Data is information about the physical and thermal characteristics of the hardware.
Usage
You can use BMC Discovery hardware reference data to:
- Identify servers, host containers or hardware containers that can be expanded in situations where space is a constraining factor in the data center.
- Identify server, host container or hardware container refresh / rationalization candidates in situations where cooling is a constraining factor in the data center.
- Identify server, host container or hardware container refresh / rationalization candidates in situations where power is a constraining factor in the data center.
This Extended Data Pack includes hardware reference data providing Rack Size, Power Consumption, Heat Output and Maximum Memory capacity.

Information Fields for a Typical Host
| Attribute | Description | Formula | Examples |
|---|---|---|---|
Hardware Vendor | The name of the hardware vendor. | IBM | |
Hardware Model | The hardware model name. | Power System S822 | |
Known Hardware Model Names | Any other names by which this hardware is known. | 8284-22A, IBM,8284-22A | |
| Number of Processors | The number of physical processors in the hardware. | 1, 2, 64 | |
Processor Type | The processor type | IBM POWER8 | |
Maximum RAM | The maximum amount of RAM in Megabytes supported by this hardware. A value of 65536 equates to 64GB. A value of 1048576 equates to 1TB. | 65536, 1048576 | |
Rack Unit (RU) | A rack unit (RU) is a unit of measure defined as 1.75 inches (44.45 mm). It is most frequently used as a measurement of the overall height of rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. | RU = Height in inches / 1.75 | 2 |
Power Capacity (VA) | The input power capacity measured in Volt Amperes. | VA = W / PF or VA = BTU / 3.412 | 1880 |
| Power Factor [This attribute is NOT shown in the Discovery UI] | Power factor is a measure of how efficiently electrical power is used in an AC circuit. It indicates the ratio of real power (used to do work) to apparent power (the total power supplied). A power factor of 1 (or 100%) means all the power is used effectively, while a lower power factor indicates wasted or reactive power. | PF = W / VA | 0.96 |
Power Capacity (W) | The input power capacity measured in Watts. | W = VA * PF or W = BTU * 0.293 | 1810 |
BTU per hour | Thermal output measured in BTUs. | BTU = VA * 3.412 or BTU = W * 3.412 | 6176 |
Power Capacity VA per RU | The input power capacity measured in Volt Amperes, per Rack Unit. | VA_RU = VA / RU | 940 |
Power Capacity W per RU | The input power capacity measured in Watts, per Rack Unit. | W_RU = W / RU | 905 |
BTU per hour per RU | Thermal output measured in BTUs, per Rack Unit. | BTU_RU = BTU / RU | 3088 |
Hosts | A link to the host or a list of all hosts using this hardware. |
