February Thesis Infographics!

Hello all!

Lately, I’ve been having issues correctly conveying some facets of the project to the general public that may not be as well versed in some of the technical concepts of the project. In an effort to make it a little easier to explain and the main concept of the project more accessible to all, I tried to find more elegant ways to express the information. Thus, the infographic was born!

Senior Project Update 7/9/2014 – New Servers, Testing and Accelerated Deployment

Hey all,

Summer has been awesome here in Rochester so far, I’ve gotten a lot done in different regards to my project!

Ultimately, I’m still in the stage of hardware and software testing, while conducting studies on 4K formats and compression schemes. All of this is valuable in appraising how much computational power I need to conduct all of the operations that are required to get the 4K footage processed as quickly as possible. Since I last posted, I’ve gotten some additional hardware to use and test, both virtually and locally. Here’s the round up of some stuff:

For the record, ALL of my Senior Project Updates can be found here, on my Senior Project Page

Last Post:

Last post, I was comparing smaller, underpowered machines to massive computing desktops to see what the differences were. They were, well, humongous. It turns out the small Micro-ITX board and setup I was using is indeed too slow for any kind of operations work. Hence, I re-purposed it for something that is different, but still useful: a netflix box!

The Alienware machine is a powerhouse even though it is still pretty old. Once I stocked it with a powerful GPU and added a bit more ram (went from 2 to 18 GB of RAM). Right now it is conducting CPU vs GPU testing as well as being used as a primary gaming machine in the evenings when I get back from work on campus. Overall, the Alienware definitely did win the battle between light and power efficient vs power hungry and high performance.

New Information:

Okay here’s all the new stuff that I promised. Recently, the school granted me two more physical server machines for use on the project. Both are 64 bit SuperMicro 2U servers, both are taking advantage of AMD’s Opteron processing technology, which I have to admit, is awesome. Both machines are powered by dual quad core CPU’s and 64GB’s of RAM.

One of my new SuperMicro machines waiting to be racked with two of my other, older Dell units.

One of the new devices is posted in the photo, it’s the machine on top and there is a second one that is identical but I already had it racked at the time the photo was taken. As you can see, both have considerably larger drive quantities. Each unit allows me to store 8 drives, and currently both have 15K raptor drives included which is awesome! 15K server drives, which I have RAIDed (laymans term for working in tandem to increase speed) is allowing me to exceed a standard hard drive read and write speed by a factor of 3! This will be invaluable for parsing and spreading out frames for my project across the cluster. Right now, each of the drives is writing at a ballpark of 82 MB/s and reading at a rate of about 260 – 280 MB/s. This is excellent because for the system I am building, read speed are far more important than write speeds for these two units. Write speeds will increase as I RAID the devices.

On top of this, I have been developing a lot of the skeleton dev software for my project. The first stage of this has been individually configuring each server since I haven’t decided to go with a major software solution like Puppet, Salt or Ansible since I’m not sure that all of the configuration time is worth the slight performance boost I would get during only the configuration phase of each server. As a result, I’ve written a full suite of scripts that kick into effect once cent is installed on each machine. I decided to go with CentOS since it focuses on enterprise support, security and longevity (the current cent dystro is supported for 7 years). Once an OS is installed, each machine can run totally autonomously once it connects to my authentication and has all of the account info it needs. The machines install all of the necessary programs and services, in addition to syncing other repositories and cloning them locally . Once each of them is all setup, it notifies me via log that it is ready to join the cluster and processing can begin. As I begin to amass more and more hardware, local and virtual, easier deployment of each unit is increasingly more important because once the semester begins again, it will be very difficult to gather extra time to set up more efficient configurations and whatnot.

In the next week or so, I should be getting access to more hardware, I also have a lot of cool code to share with you all; most of it is linux based deployment, disk testing and a variety of others as well. Look for that in my Git and other repos, hosted here!

Upgrades, Upgrades, Upgrades

Hey All!

With my return to Rochester, New York to spend a couple weeks working before the next academic semester, I’ll be posting a lot of neat content relevant to the assortment of projects I have planned! Here’s a quick breakdown!

Moving some servers around! I’ll be converting a Windows 7 server to a CentOS server to host this website on! I’ve been using WordPress for a significant period of time and it’s been great! The problem is WordPress’s business plan and pay per add on web features when you host through their web service. After some work with CentOS, I realized I have plenty of power to be hosting else where! I’ll still be running WordPress, the new version 3.8 is pretty snappy! But I want more power with hosting and SEO and back end programming, so hosting locally it is! As a note, if this site goes offline for a couple of days, don’t be alarmed!!

Building another NAS! I have the parts, the case, (beautiful NZXT 210 Elite in sleek black) and the drives, but now it’s time for the build and setup! It’s going to be a real cool setup on the inside so I’ll be sure to post photos! I’ve been hosting somewhat of a local datacenter for my operations, clients and products but now it’s time to make a bit more of a contiguous storage pool, especially given RIT’s internet speeds here! The power supply is coming in in two days and then building will go forward pretty quickly! This should comfortably keep my storage ceiling around 20tb, even with redundancy and network shares!

On top of this, I will also be setting up my final server as a general use server, with a file system and user access panel. Currently experimenting with Windows Server 2012 datacenter Edition, but also looking into Ubuntu Server and the possibility of adding in another CentOS machine! With all of these installs, I’ve tapped out all of our networking opportunities so I’ll be installing a mid sized rack switch and firewalls. Time to take this setup to a full blown cluster now that I have the capabilities for web serving, file serving and administration and distributed rendering and computational engines. Hopefully the setup starts to look a bit more professional as well, as compared to the humble beginnings of the project, shown below!
