Digi POS Case Study The author of this response is asked to evaluate the DigiPos case study and offer responses to four major questions. First, the author is asked to examine and assess the main computing problems that DigiPos faced with regard to the system upgrades involved and discussed in the case study. Second, the author is asked to discuss the solutions that were used to solve the problem. Third, the author is asked to compare and contrast the Quantum Blade and Retail Blade hardware and software solutions. Fourth and finally, the author is asked to assess the means by which total cost of ownership (TC) was managed along with an opinion of what will or will not work in addressing the same (DigiPos, 2013).

Questions Answered

As far as the challenges or problems that were faced as mentioned by the case study, the earlier part of the study enumerates that delivering unique retail solutions that maximized the return on investment of the firm as well as helped DigiPos retain its competitive advantage was one challenge. Another challenge was constructing a proper framework, or "roadmap', towards offering predictability and acceptable levels of performance via the use of embedded processor technology (DigiPos, 2013).

As far as the solutions offered, those are also clearly articulated in the case study. It is noted that DigiPos has made it a point to operate exclusively and over a long period of time with a singular technology...

It is also noted in the case study that they do not limit the technology used to Intel systems but also different chipsets in general, including the i7 and the Q67 Express Chipset (DigiPos, 2013). Also, they use Solid State Drives rather than traditional platter hard drives. The upsides to SSD's are obvious. Even though the upfront cost of SSD's are much higher, the reliability of SSD's also much higher given that there are no moving parts in the drives which is far and away the most common cause of hard drive failure (Domingo, 2013).
As for the differences and similarities between the Quantum Blade and Retial Blade systems, there are clear benefits to both but the Quantum option is obviously much better. Both the Retail and Quantum blade offerings are better than traditional retail POS systems because upgrading the systems are not "all or nothing" propositions. In other words, if there is a part of the system that is deficient and needs to be upgrade, it is not necessary to scrap and replace the entire system. Instead, only the parts that are in need of upgrade, like the motherboard or the memory, can simply be swapped out. The two blade systems are different in that deviations of any sort from expected parameters was a fairly major liability with the Retail Blade systems and this was greatly improved upon with the better energy efficiency and performance curves of the Quantum Blade systems offered by Intel in 2009.…
