There are several ways you can access Virtual Machines (VMs) in the Big Data Lab. VMs can be accessed through the vSphere client, Remote Desktop, or SSH. To access VMs remotely, you must first connect to the Computer Science VPN.

VMs in the Big Data Lab can be accessed through the vSphere Web Client, vSphere Desktop Client (Windows only), though Remote Desktop Connection (only for Windows VMs), or through SSH (only for Linux VMs). In order to access virtual machines from your laptop, from lab computers outside of Adams and Weed Hall, or from anywhere off campus, you must first connect to the Computer Science VPN. Big Data Lab VMs are subject to the Virtual Machine Policy and the Acceptable Use Guidelines.

Using the vSphere Web Client

  1. Launch a web browser. On computers in Adams 204 or 019, launch Google Chrome (under Applications->Internet, or type “google-chrome” in terminal)
