Which device is used for remote management of servers for troubleshooting and monitoring?

The device designed specifically for remote management of servers for troubleshooting and monitoring is the Integrated Lights-Out (iLO) for HP servers or the Integrated Dell Remote Access Controller (iDRAC) for Dell servers. These technologies provide administrators with the ability to access server hardware remotely, perform troubleshooting tasks, and monitor system health without being physically present at the server location.

iLO/iDRAC offers features such as remote console access, power management capabilities, and hardware health monitoring. With these tools, administrators can perform tasks such as rebooting the server, updating firmware, and checking system logs, all from a remote location. This is particularly useful in data centers where physical access to servers may be restricted or impractical.

In contrast, while a KVM switch allows multiple servers to be controlled from a single keyboard, video monitor, and mouse, it does not inherently provide remote access capabilities over a network. Network switches and routers are critical for directing traffic within a network but do not offer the specialized management features necessary for troubleshooting and monitoring server hardware.
