Server Virtualization Essay

To begin our IT solution, our company will look at the center point of all technology, which is our on-site data center. In the data center we have 2 physical servers, which are rack mounted with our uninterruptable power supply (UPS). This area also has its own dedicated A/C units. Our servers are designed for virtualization, which means multiple virtual servers can run on one server. These 2 servers also mirror each other and provide an on-site backup. There will be a fiber channel backbone between the 2 physical servers so data can be sent between them as needed. These 2 servers are Intel E 7450 zion, 6 core, 2.4GHz processors with 128GB memory and the operating system is VMware ESXi version 3.5 with 5 300GB 15K RPM drives which give approximately 1.2TB of total disk space. It also includes 4GB network cards with VMware virtual center version 2.5. Also, our company will have a 3 year 24/7 onsite support.

Virtualization’s rate of adoption is completely characterized by the five characteristics described in the framework for the concepts of innovation (Luftman & Bullen, 2004, p. 189). It is perceived to be better than physical servers in its ability to host multiple operating systems and share the host’s resource. Its encapsulation of resources allows it to operate as if it was a physical machine yet it is totally virtual giving it a relative advantage. It is compatible with all baseline operating systems on the market. Complexity in implementation is minimal making it more attractive to adopt. The vendors allows for free downloads and trials. Its visibility in competition with Microsoft’s Hyper-V has shown multiple advantages. (Luftman & Bullen, 2004, p. 190)

Network Based Virtualization is abstract storage of data applications from the host machine. This is well achieved through fibre channels connection between the machines and the servers running virtualization. The respective operating systems on the separate machines are not a factor to consider as they work independently. For it to achieve its expectations, the following services must be provided as below:

I believe that my two strongest characteristics that were mentioned by Alison Lake and Carl von Baeyer are taking good notes because when you are taking notes you not only listen to professor using the auditory memory but also you use your motor memory that helps you to remember material much faster and better. Also, it is almost impossible for most of the people to remember material just by listening to the professor because the next day most of the information is forgotten. When I came to my first nursing class I didn’t pay enough attention to the notes. I thought that power points will be enough for me but I was wrong because just after the class I almost forgot everything that professor said and I had to ask my classmates to share the notes.

Virtualization is a combination of software and hardware engineering that creates Virtual Machines (VMs) - an abstraction of the computer hardware that allows a single machine to act as if it were many machines, or a computer that does not physically exist as a piece of hardware. The hardware that is seen by the operating system is emulated in an effort to separate the physical hardware from operating system. This allows the virtual machine to be moved and hosted on any machine independent of hardware. Virtualization technology is possibly the single most important issue in IT and has started a top to bottom overhaul of the computing industry which is why many companies around the world have are using its softwares to enhance their business opportunities.

Commercial data centers like Equinix and Amazon have to be judicious expanding capacity considering lengthy construction and heavy capital investment. A data center contains aisles and aisles of server cabinets thousands with each costing more than a quarter million containing 64 specialized laptop sized servers essentially a computer. Networking cabinets go together with server cabinets in order to electronically connect any server to another through high-speed fiber cables. The networking cabinets of today consume 25% of the useful floor space for IT cabinets but consist of 40% of the total cost. The data center is clamoring for IT gear that supports a new technology known as Network virtualization to address the conservation of space and

As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.

Virtualization is being able to give a physical device the power, through the use of software, to do more than that physical device was technically designed and able to do (Santana, 2014, p. 12). For example, a server can only run one operating system at a time. However, when a hypervisor is used in a server, the hypervisor is a layer of software that acts like the server itself so that many operating systems can be run from that one server. The hardware, in this case a server, has been virtualized. The goal is to use all of the computer’s resources all of the time, and the only way to do that is to have enough things running that the resources are being used consistently and efficiently. An analogy for this could be online classes. If each teacher only had one student, the teacher’s resources of time and expertise would not be utilized efficiently because that one student will not need help all day, every day. If the teacher is assigned to fifteen students, the students can still get help when needed from the teacher, and they would not even be aware that they are not alone in the class. Because it is an online class, the teacher does not need any more physical resources to teach an entire class than was needed for one student. The students are receiving the benefits of being taught by that teacher without needing to be with him or her physically.

Switch to virtual machines instead of physical servers. This internal business strategy aligns with the overall mission to reduce costs by 5% to fund new projects, such as providing warehousing services to customers. In addition, updating this technology will reduce manpower needed to upkeep servers and free them to work on other projects.

Virtualization is the abstraction of a hardware or software system that lets applications run on top of the virtualized environment without the need of knowing the underlying resources available. The virtualized environment is otherwise known as the virtual machine

“Of the 281 million people age 5 and older in the United States in 2007, 55.4 million individuals — or 20 percent — reported speaking a language other than English at home.” (Newsroom) As the number of non-English speaking people in our country increases there is also a debate going on as well. This debate is over whether American Schools should offer a bilingual education to accommodate these people or not. “Bilingual Education is the practice of teaching non-English speaking children in their native language, while they are learning English.”(Bilingual Education) In “The Achievement of Desire”, Rodriguez writes about his experiences growing up as a Mexican-American student and the toll that it took on his life. Bilingual education may

A more proficient IT infrastructure is required as the use of more software increases the needs of powerful and faster PCs. One of the trends that can help this issue is Virtualization. This technology is described as the “abstraction” of the physical elements (such as network resources, operating system and storage) into virtual ones (Portnoy, 2012, p.2). Virtualization allows a physical machine to run several virtual machines (VM).

This business case investigation discusses in depth about the process of virtualization of servers in an organization and the various benefits of doing so. Giving a brief introduction to the concept of virtualization, it was introduced in the late 1960s when the resources of mainframe computers were divided between several applications. [1] The term virtualization has since then been expanded in terms of practical application. The conversion of the physical server into a pool containing several virtual machines which act individually as one computer is known is hardware virtualization.
