1. Dynamically Expanding Virtual Hard Disk which seemed like the better candidate but every time we tried to load an image that was classified as this it would fail Finally we had to establish how the networking aspect of the project was going to work Since we could not really manipulate how the network was set up and we had to essentially hot swap our system into the network come implementation time we had to keep things pretty much as they were and work our system into it For the majority of the project we had assumed that the networking aspect was done through static IP addresses and we knew this would be one of the last steps so we never put much thought into it We found ourselves very stumped when we discovered there was no static IP set on either the server or the touch screen PC How would info be passed from the server to the touch screen PC if neither knew where to find the other at all times The answer to our problem was in the router settings as well as the network map we were provided It took us a little while to connect the dots but we determined that the MAC addresses were being used to reserve IP addresses through the router s DHCP propagation We had some suspicions that the software DynDNS might have had something to do with the network as the software was being run on the server However we later figured out that this piece was actually responsible for the VNC access which our client was using to remotely access the se2. Assembled system setup that meets our requirements e Successfully virtualized all the aspects of the system that we could e Created a backup and contingency plan for the infrastructure e Documented and made recommendations for optimization of Python scripts e Developed a user manual for continued project maintenance and accessibility We felt the project had its challenging moments but also its victories much like any big project Initially our biggest concern was timing We were unable to order our equipment until January due to funding issues and the hardware in question did not arrive until mid February That effectively removed a month and a half of our project time at least in terms of building the system We spent most of that period playing around with our own copy of Windows Server 2012 as well as studying the scripting language Python so we could understand what was happening in the scripts We also initially thought the process of converting a physical drive to a virtual one would be much more difficult than it actually proved to be We tried a Microsoft converter as well as a VMware converter 3 but ultimately the Sysinternals tool we used disk2vhd met our needs 2 The process is as simple as inserting an external hard drive and pointing the tool at what drive you want to convert We experimented with this quite a bit during this initial period so that we were prepared to capture the images when we got our hardware When o

6. RAID 5 configuration for drive failure protection The available memory this provided was lot more than what the system needed to function but we wanted to leave room for expansion down the road Our client had also asked us to leave the operating system on the host machine as a Windows based one because it was what he was most familiar with We decided to go with Windows Server 2012 for two reasons 1 it contained Hyper V 3 0 8 which we had planned to use as our hypervisor and 2 it had the latest in security technology something we also wanted to put some focus on Since Server 2012 looks and feels a lot like Windows 8 an operating system we were not overly familiar with we wanted to make it feel a little more familiar We used a third party add on called Classic Shell 9 that allows for some nice modification of the user interface and namely we used this to create a Start button the button in the bottom left hand corner of Windows user interface Windows Server 2012 does not contain this by default and this is the same for Windows 8 This may seem like a fairly trivial thing but it was something that we felt was a Staple of familiarity and functionality Once we had the spine of the system built we went through the usual steps from there such as stress testing and installing the server into our rack We conducted our stress testing using a program called Prime95 with a custom test to utilize the majority of our RAM 10 From th

9. ere the next logical step was to capture hard drives of the computers running in the house and virtualize them but we chose to do several test runs of the procedure before going out to the house to capture the actual drives To do this we used a Sysinternals tool called disk2vhd which converted physical hard drives into virtual ones 2 Around this time we began work on a couple other aspects of the project We were required to build a website which can be found on the DVD attached to this report so work was commenced on that We were also asked to take a look at the Python scripts that were developed for the original project 1 as some of them were generating errors ona regular basis on the system Unfortunately none of us had any real knowledge of how Python worked so we had to doa little research on our own to get familiar with it We had expressed to our client that if we thought it was possible we would convert these scripts over to a language we were more comfortable with Perl However at the time we did not have access to the code and severely underestimated how much of it there was We quickly settled on going through it all and documenting it to the best of our abilities because the original author had only partially done this The results of this procedure will be discussed in the next session and the documentation along with the scripts is appended to this report for your convenience Once we were able to get into Disco
10. ject the biggest thing we would stress would be thoroughly researching the system before setting out to work on it In our case the documentation we were given to work with felt really scattered and it made having a cohesive understanding of the system something difficult to obtain initially There were a lot of little surprises we kept discovering as we went through the work and ultimately had we had a better understanding of how the system was working we could have avoided some unnecessary steps Another point we would really stress is extensively looking into the hypervisor you plan on using Something that may seem like an obvious inclusion or feature may not actually be part of the package and it is much better to discover these things prior to doing a bunch of work with the system and then having to undo it much like what we had to do Page 1 3 CONCLUSION Overall we hope our project can become an integral part of the Discovery 4 infrastructure We feel like this upgrade was necessary step forward for the house and we enjoyed having a part to play with this incredible building As a group we feel working a project that was environmentally mindful has been very refreshing and the sustainable values that the home embraces are very much aligned with our own We have learned a lot from this project both in the realm of IT but also in the realm of project management We hope to take the knowledge we have learned over the past few months
