System Inventory

Knowing exactly what hardware is inside your server is crucial for everything from asset management to troubleshooting. The system inventory provides a detailed list of all detected components, their part numbers, and their basic status. It's like having a complete build sheet available at any time.

This chapter shows you how to navigate the inventory to verify your server's configuration.

Best Practice: Inventory vs. Monitoring

While the Hardware status pages (Chapter 4) are for live monitoring of performance metrics like temperature and fan speed, the System Inventory is for verifying the static details of the hardware itself—what it is, who made it, and what its model number is.

To begin, navigate to System Inventory in the sidebar menu. The information is organized into several tabs.

Reviewing system, processor, and baseboard details

The first few tabs give you a high-level overview of the core system components.

• System: Displays basic identifiers like the server's Manufacturer, Model, Serial Number, and currently installed BIOS Version.

• Processor: Shows detailed information for each installed CPU, including its Model, Max Speed, Total Cores, and health State.

• BaseBoard: Provides details about the mainboard, including its Model, Asset Tag, and a list of onboard network interfaces with their MAC Addresses.

Checking memory controller and DIMM information

The Memory Controller tab is essential for verifying your server's RAM configuration and diagnosing memory-related issues. It lists every DIMM slot and the module installed in it.

Look for key details like:

• Capacity MiB: The size of the memory module.

• Speed: The operating speed of the DIMM.

• Manufacturer and Part Number: Useful for ordering exact replacements.

• Health and State: Indicates if the DIMM is enabled and healthy. A "Not Present" or "Faulty" status points to an empty slot or a failed module.

ServiceLabel	The physical label on the motherboard for the DIMM slot (e.g., CPU0_DIMM_A1).

Verifying power supply unit (PSU) details

The Power tab lists each installed Power Supply Unit (PSU). This is the best place to verify PSU models and check for redundancy issues.

[Image, EXISTING, Source: 11.5: Screenshot of the System Inventory > Power tab.]

For each PSU, you can verify:

• Model and Manufacturer.

• Power Capacity Watts: The maximum output of the PSU (e.g., 1600W).

• Power Supply Type: Whether it's an AC or DC unit.

• Health: A Failed status here indicates a PSU needs to be replaced.

Field Reference (Power Control Info)

Field	Description
Name	The identifier of the power supply unit.
Manufacturer	The company that manufactured the PSU.
Model	The model number of the PSU.
EfficiencyPercent	The energy efficiency rating of the PSU.
FirmwareVersion	The current firmware revision of the PSU.
PowerCapacityWatts	The maximum power output capacity in watts.

PartNumber	The manufacturer's part number.
SparePartNumber	The spare part number for replacement.
Health	The health status of the PSU (e.g., OK, Failed).
State	The operational state of the PSU (e.g., Enabled, Disabled).

Reviewing thermal and fan information

The Thermal tab provides an inventory of all fans and temperature sensors in the system. While Chapter Hardware Health covers live monitoring, this tab is for viewing the static properties and thresholds of these components.

[Image, EXISTING, Source: 11.6: Screenshot of the System Inventory > Thermal tab.]

• Fan Info: Lists each fan and its maximum rated speed.

• Temperature Info: Lists each temperature sensor and its configured fatal (UF), critical (UC), and warning (LC, LF) thresholds. This is useful for understanding the server's designed operating limits.

Pro Tip: Match the Part Number

When replacing a failed PSU or DIMM, always use the Part Number from the system inventory to ensure you order a compatible component. This avoids compatibility issues and potential system instability.

Listing PCIe devices and functions

The PCIe Device and PCIe Function tabs allow you to see all the expansion cards and onboard controllers connected to the system's PCIe bus. [Image, EXISTING, Source: 11.7:
