  1. Virtual Life Clinton A Jones Eastern Kentucky University Department of Technology

  2. Outline • Motivation: Need for more advanced network with limited space • Introduction: Research on Virtualization • Problem Statement: Install multiple virtual servers and configure them to load balance on the same physical disk • Proposed Solution: How to solve the problem • Implement Solution: Set Up and Test Proposed Solution • Results and Conclusions: Success, or a Learning Experience? • Future Work: Implementation

  3. Motivation • Servers take up precious, expensive physical space • Many identities utilize multiple physical servers in a load balancing implementation • Even small, home networks sometimes use multiple physical servers to store different resources on • My own home network utilizes three separate servers for different, but necessary resources • I need to make my network more flexible, but shrink it’s physical and environmental impact

  4. Introduction • This project investigates the corporate use of virtual server clusters and examines the feasibility of utilizing a scaled down application in a home network environment • I wanted to minimize the space taken up by multiple physical servers, as well as the power consumption and heat production of those servers

  5. Introduction • Research: • www.vmware.com • http://blogs.msdn.com • Support.microsoft.com • http://www.dabcc.com • http://lbvm.sourceforge.net

  6. Problem Statement • Develop Virtual Replicas of existing physical servers • Develop load balancing protocols for said virtual servers to allow for smoother network traffic

  7. Problem Statement • To make this: • Into this:

  8. Proposed Solution • Investigate pre-built virtual cluster solutions • Investigate Free Solutions: Linux, Embedded • Utilize Windows Server 2008 Hyper-V technologies • Determine how each different virtual machine integrates with the host hardware, and how it communicates on the network

  9. Proposed Solution • Obtain Hard Disc Drives large enough to support multiple virtual environments • Install and evaluate VirtualPC 2007, VMware, Virtual Box, and XEN for Linux. • Evaluate Hercules Load Balancer Virtual Appliance for VMware

  10. Implement Solution • Installed openSUSE 11.2 and the XEN virtual environment • Free Solution, however difficult to implement on my network • Found it difficult to attach to shares from various Windows Flavors. NLB was non existant.

  11. Implement Solution • VirtualBOX • Ubuntu Linux • Samba easy to configure, shares easy to connect to from Windows. • SWAT Web Interface for Samba easy to configure. • Network Load Balancing difficult and unreasonable to implement in this scenario

  12. Implement Solution • VMware • Successfully virtualized Mac OS X • Virtualized Mac OS is almost useless for the task at hand • No network communications from Mac OS or to Mac OS. • Ill suited for server environment

  13. Implement Solution • VirtualPC • Easy to setup, configure and get started • Could only run one Virtual Machine at a time • Since only one VM was active at a time, it was “virtually” impossible to implement NLB

  14. Implement Solution • Hercules Load Balancer Virtual Appliance • Works with VMWare. • “A tiny but mighty tcp load balancer” • Can run on as little as 32MB of ram and as little as 4MB of disk space

  15. Results

  16. results • Success in reducing the number of servers on my home network to a single physical machine • Success in finding a new understanding of load balancing and mixed network environments • Reduced the temperature in my “office” by several degrees, and notice my electricity bill has diminished.

  17. Conclusions • Found that NLB is more involved than I anticipated • Unfortunately, was not able to implement load balancing to the degree that I wanted • Settled on running multiple Virtual Machines with separate, unlike tasks to spread the workload over many virtual CPUS

  18. Conclusions • From my involvement in this project I learned that there are “stand alone” load balancer network appliances • Similar to a hardware firewall in that it is a hardware and software package • I have a new understanding, while still basic, of how to navigate, and survive in the Linux CLI

  19. Conclusions • I determined that multiple virtual servers on a single physical machine requires a hard wired network connection • No two VM’s would utilize the wireless network connection at one time

  20. Future Work • Includes “remodeling” my host machine to include a more powerful CPU and multiple network cards • Further pursuing the Hercules Load Balancer and Vmware Virtual Appliances to implement a true virtual cluster environment
