Product Overview of the HP 336045-B21 Server Console Switch

The HP 336045-B21 is a specialized device designed to manage multiple servers efficiently. It serves as a Console Switch, allowing control and monitoring of up to 16 servers through a single interface. This switch is part of the Kernel-based Virtual Machine (KVM) category, offering a streamlined way to interact with servers. The technical specifications include a 0x2x16 configuration, RJ-45 connectivity, a 1U form factor, and a rack-mountable design. Additionally, it operates on Alternating Current (AC) power with voltage compatibility of 120/230V and supports rack mounting.

Server Console Switch and Kernel-based Virtual Machine (KVM)

A Server Console Switch is a tool that simplifies the management of multiple servers. It enables a user to control and monitor several servers using a single interface, reducing the complexity of handling individual server connections. The term 'Kernel-based Virtual Machine (KVM)' refers to the technology that allows multiple virtual machines or servers to run on a single physical machine. It's like having several computers within one, and the console switch helps in managing these efficiently.

0x2x16 Configuration

The '0x2x16' configuration specifies the switch's layout and capabilities. It indicates that the switch has zero local users, and two remote users, and can connect to up to 16 servers. This configuration allows two remote users to access and control the servers through the switch.

RJ-45 Server Connectivity

The RJ-45 designation refers to the type of connector used to connect the switch to the servers. RJ-45 connectors are commonly used for Ethernet networking connections. In this context, they facilitate the connection between the server console switch and the servers for data transmission.

1U Form Factor

The '1U' form factor indicates the physical size of the switch when mounted in a rack. It's a standard measurement for height in rack units, and 1U is relatively compact. This is beneficial for data centers or server rooms where space is valuable, as it allows for efficient stacking of multiple devices in a vertical rack.

Rack-Mountable Design

The 'Rack-Mountable' design means that the switch is designed to be installed in a server rack. A server rack is a structure that holds multiple hardware components, including servers and networking equipment, in a systematic and organized manner. The rack-mountable feature is practical for environments where space needs to be optimized.

Alternating Current (AC) Power and Voltage Compatibility

The switch operates on Alternating Current (AC) power, the standard type of electrical power supplied to homes and businesses. The voltage compatibility of 120/230V means the switch can adapt to different electrical systems commonly found in various regions. This feature ensures flexibility and compatibility in diverse power environments.

Benefits of Using HP 336045-B21 Server Console Switch

  • Centralized Server Management: The switch allows for centralized control and monitoring of up to 16 servers, reducing the complexity of managing multiple individual connections.
  • Remote Accessibility: With two simultaneous remote users, it facilitates remote server management, enabling flexibility and accessibility from different locations.
  • Compact Design: The 1U form factor is space-efficient, making it suitable for environments where optimizing rack space is crucial.
  • Versatile Connectivity: RJ-45 connectivity ensures compatibility with standard networking cables, making it easy to set up and integrate into existing networks.
  • Rack-Mountable Convenience: The rack-mountable design enables easy installation in server racks, contributing to a neat and organized server infrastructure.
