# 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](/documentation/modules/assets/tabs/rack_items.md) 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](/documentation/tabs/impact_analysis.md) 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](/documentation/modules/management/contract.md) 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.

## Documents

The [document](/documentation/modules/management/documents.md) tab lets you link different types of file to a material (PDF, txt, png, etc.) You can attach a document already uploaded to GLPI or add a new one directly from this tab.

## Tickets

View all [tickets](/documentation/modules/tabs/tickets.md) linked to the computer

## Problems

This tab refers to all hardware-related [problems](/documentation/modules/assistance/problems.md). Problems can also be linked to tickets, projects, etc. This allows you to have a complete scenario when necessary.

## Changes

[Changes](/documentation/modules/assistance/changes.md) 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.

## Reservations

The [reservation](/documentation/modules/tools/reservations.md) 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.

## Historical

[Historical](/documentation/modules/tabs/historical.md) lists all the actions carried out on the object in question

## 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.
