# 12 Fields Every Data Center Asset Inventory Should Track

> The twelve data fields that make a data center asset inventory actually useful for audits, migrations, and day-to-day operations.

Published 2026-10-17. Category: Asset Inventory.

A good asset inventory answers three questions quickly: what do we have, where is it, and who is responsible for it. These twelve fields cover the practical needs of most teams without turning data entry into a full-time job.

## 1. Unique asset tag

A single tag that stays with the device for its life. Do not rely on hostnames or IP addresses, which change.

## 2. Manufacturer and model

Needed for support contracts, spare parts, and capacity planning. Record the exact model number rather than a family name.

## 3. Serial number

The most reliable way to match a physical device to a purchase record and a warranty. Verify against the label on the device, not just the paperwork.

## 4. Physical location

Site, room, row, rack, and starting U position. Consistent naming here is what makes the rest of the inventory searchable.

## 5. Rack units occupied

Height in U lets you plan available space and see where you are close to full.

## 6. Power connections and draw

Which PDU and outlet each power supply is plugged into, and typical load. This is critical when planning additions or investigating a circuit trip.

## 7. Network connections

Switch and port for each interface, plus the connected cable's label. It turns "what breaks if we unplug this?" into a lookup.

## 8. Owner and business function

A person or team and the service the device supports. Orphaned equipment with no owner is a common source of wasted power and risk.

## 9. Lifecycle status

Planned, installed, in production, spare, retired, or awaiting disposal. Status shows what can be reclaimed and what needs attention.

## 10. Purchase and warranty dates

These make renewal and refresh planning proactive rather than reactive.

## 11. Support contract and vendor contact

Who to call and what coverage exists. Saves time during an incident.

## 12. Last verified date

The date someone physically confirmed the record. It tells you how far to trust each entry and where the next audit should focus.

## Frequently asked questions

### How often should a data center inventory be physically verified?

Many teams reconcile at least annually and before major projects such as migrations or decommissions. Frequent-change environments may spot-check more often.

### Does Fieldbench perform physical inventory audits?

Yes. Technicians walk racks, record serial numbers and asset tags, and reconcile the findings against your existing records.
