Abstract
A modular server chassis enclosure controller (EC) on-premises keyboard video and mouse module has an EC frame buffer memory and an EC virtual network computing (libvnc) client process. The libvnc fetches an EC frame buffer memory address, displays an on-screen display (OSD) screen to a user and accepts user selection of a blade server deployed in the modular server chassis from the OSD. The libvnc receives a virtual network computing (VNC) streaming session over transport layer security, from a VNC computing server process of the selected blade server. The libvnc determines whether the VNC server process has data to send and, if it does, reads graphics data from the virtual network computing server process and writes the graphics data from the VNC server to the EC frame buffer memory address. The graphics data is displayed on an on-premises monitor coupled to the modular server chassis from the EC frame buffer.
