KVM switch over IP devices use a dedicated micro-controller and potentially specialized video capture hardware to capture the video, keyboard, and mouse signals, compress and convert them into packets, and send them over an Ethernet link to a remote console application that unpacks and reconstitutes the dynamic graphical image. KVM over IP ...
The Dell Remote Access Controller (DRAC) is an out-of-band management platform on certain Dell servers. The platform may be provided on a separate expansion card , or integrated into the main board ; when integrated, the platform is referred to as iDRAC .
NDIS Miniport drivers can also use Windows Driver Model interfaces to control network hardware. [19] Another driver type is NDIS Intermediate Driver. Intermediate drivers sit in-between the MAC and IP layers and can control all traffic being accepted by the NIC. In practice, intermediate drivers implement both miniport and protocol interfaces.
The iKVM switch in the Dell enclosure is an Avocent switch and one can connect (tier) the iKVM module to other digital KVM switches such as the Dell 2161 and 4161 or Avocent DSR digital switches. Also tiering the iKVM to analog KVM switches as the Dell 2160AS or 180AS or other Avocent (compatible) KVM switches is possible. [2]
The MegaRAC from American Megatrends is a product line of baseboard management controller (BMC) firmware packages and formerly Service Processors providing complete Out-of-band, or Lights-out remote management of computer systems independently of the operating system status or location to troubleshoot computers and assure continuity of service.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Devices like Dell DRAC also have a slot for a memory card where an administrator may keep server-related information independently from the main hard drive. The remote system can be accessed either through an SSH command-line interface, specialized client software, or through various web-browser-based solutions. [4]
Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
