KVM switches and remote power managers

KVM Switches

A KVM switch enables a single keyboard, video monitor, and mouse to control multiple computer servers, eliminating the wasted space and clutter created by multiple, redundant input/output (I/O) devices. From a single console, the KVM switch lets IT managers access an entire rack or room full of servers.

KVM switches provide many advantages for consolidating control of multiple servers and other devices. These include powerful pre-boot functions, such as editing Complementary Metal Oxide Semiconductor (CMOS) settings and power cycling your servers, BIOS-level access and control of multiple racks of servers from a single console.

Many KVM switches allow remote access over IP. Using this type of KVM switch allows you to leverage your network infrastructure, which makes adding users as easy as adding an IP address. IP KVM switches also eliminate distance limitations imposed on analog equipment. Tapping into the power and widespread availability of IP networks, users can control data centre devices regardless of location.

Remote Power Managers

Remote power managers provide the ability to power cycle or reboot the network without interrupting all the equipment attached to the UPS. Remote Power Managers can also be used in conjunction with a console server or Remote KVM switch to initiate a graceful shutdown for a wide variety of servers, and provide remote equipment monitoring to ensure that software is running correctly.

Another important function that remote power managers can provide is power sequencing. During power-up, each of the power outlets can power on sequentially, which distributes the load and eliminates the risk of a blown fuse or tripped circuit breaker. Highly useful in a networked data centre, power sequencing gives system administrators the option to turn on certain devices before others.

A further way remote power managers help to maximize data centre utilisation is through environmental monitoring. Remote monitoring of temperature and humidity sensors on devices makes sure that critical environmental conditions are maintained for maximum uptime.
