1. Server
Servers are one of the most common devices in a cabinet. They are usually used to store and run data, applications, and services. Different servers usually use different operating systems and processor architectures to meet different needs. Servers can use measures such as redundant power supplies and redundant storage space to ensure data security and reliability.
2. Switch
A switch is a network device with multiple ports for forwarding data packets within a local area network. A switch enables communication between different network devices and can manage data flows based on MAC addresses to make it more efficient. Switches are usually installed in cabinets to save space and facilitate management.
3. Router
A router is a network device that forwards data packets from one network autonomous system to another. Routers can connect various networks, such as local area networks, wide area networks, and the Internet. In a cabinet, a router is usually used as a gateway device.
4. Storage Equipment
Storage devices are devices that store data in computers. They can be divided into internal storage and external storage. Common storage devices in cabinets include hard disk arrays, tape libraries, network storage devices, etc. They are usually used to store and back up large amounts of data and files.
5. Wiring equipment
Wiring devices are also common in cabinets. They are used to manage and connect various devices. Common wiring devices include cables, optical fibers, panels, plugs, etc. They can make the connection between various devices in the cabinet more tidy and clear.
6. Uninterruptible Power Supply (UPS)
Interruptible power supply is a commonly used backup power system used to provide power protection .
7. Power Distribution Unit (PDU)
PDU is a product designed to provide power distribution for rack-mounted electrical equipment. It has a variety of specifications with different functions, socket combinations and installation methods.
In short, there are many types of equipment in the cabinet, including servers, ups, pdu, storage devices, wiring equipment, etc. They have different functions, but they are all key equipment supporting modern computer networks.
