# Racks

A rack is a piece of equipment such as a patch bay or computer cabinet used to organize, host and physically connect different network equipments and servers in a datacenter or technical room.

A rack is a dedicated object in GLPI that virtually represents the physical structure of a rack or cabinet. It is designed to :

* **Organize equipment**: A rack is used to visualize and manage the physical equipment (servers, switches, routers, UPS, etc.)
* installed in it.
* **Facilitate physical management**: It enables you to track where equipment is installed in a physical space (technical room, datacenter, etc.).
* **Optimize space**: Racks help ensure that space is used efficiently, and that there's still room for new equipment.

## Items

The Item tab shows the position of each element in the rack. You can modify, add or remove an item from your park to your rack.

## Impact Analysis

Impact analysis enables an infrastructure diagram to be drawn up, showing the dependencies and impacts in the event of equipment loss. This can be saved and exported

***

## Contracts

GLPI supports contracts management, in order to manage contract types such as loan, maintenance, support...

Contracts management allows to:

* make an inventory of all contracts related to the organization assets
* integrate contracts in GLPI financial management
* anticipate and follow contract renewal.

## Changes

Changes lists all changes related to a material. From this tab, you can't link a change directly, you can do it from **`Assistance`** > **`Changes`** > **`Items`**. You can create a new change from this page, which will be linked to the material you have selected.

<a href="/athome-docs/tabs/changes.md" class="button secondary">Go to Changes</a>

***

## Reservations

The reservation tab lets you reserve equipment, view the reservation schedule, or cancel the possibility of reserving this equipment. By default, equipment cannot be reserved; you must first authorize this action manually.

## History

The *History* tab is used to show any changes made to an item. The following information about the changes is available:

* ID of the change.
* Date and time the change was made.
* User who made the change. If this field is not filled, it means that the action was done automatically (For example: automatic inventory update).
* Field that was changed.
* Description of the change that was made.

The description of the change represents either the difference between the old and the new value (For example with location field: Change HQ to Remote Office A), or the explanation of the action which was carried out (For example: Uninstallation of a software: "Gimp 2.0").

{% hint style="info" %}
For dropdowns or objects with a parent/child relationship, the modification of a child will appear in the history of the parent element.
{% endhint %}

## All Information

For an item, all information is displayed on one page from the *All* tab. This shows all of the tabs of an object's form in one view, one below the other.
