SCSIraidGURU’s World

This starts in the early 1980s when I was in high school.  It meanders through 30+ years of technology.  This section contains what I have done in various areas of engineering and programming.  Projects I have worked on.  Code I have written.  Solutions that I have helped vendors develop and implement.   I have been moving away from tinkering with hardware and more into website development along with learning more about the components of the WordPress servers.   LAMP:  Linux, Apache, Mysql or MariaDB along with PHP.    I have spent more time working with the Fortinet 60E firewall configuration.    I started a new project on streaming instead of cable.   I bought a Roku Ultra.   I have been spending time on ITPro.TV and Hillsdale College’s videos. 

My data center writeup for the HP Blade technology

This was my biggest project for Americorp Financial.  Virtualize their network and migrate from physical servers to a HP Blade Center. 

I have been going through the Cisco OCG for the Cisco Certified Design Associate.  I remember doing this write up 2011-2012.  I wonder how my methodology from my B.EE studies differs from the CCDA.   I started with a list of what management wanted in the design.   It was over 25 items.  I researched it based on what was possible, what could be done at a high cost and what was impractical to do based on our budget and other constraints. 

The main problem with the Cisco and HPE design best practice is they scale up.   With Americorp Financial, I had to scale down.   The budget constraints made designing an extreme challenge.

Some of the links could be broken.  I wrote this up in 2011-2012.  It was the presentation I gave to the CFO on implement the data center project.

=(PMT(B33/360*365/12,60,-B16))*0.998317 is the formula Excel and T-Value match within a penny. 

One of the things that I needed to solve was how to get my project numbers to match in Excel and T-Value.  I found that PMT was always off from T-Value.   So I applied mathematical concepts to solve for a skew factor that fixed the issue.
