Instructions:
An effective information technology manger must be as adept at the application of data storage techniques relative to business continuity. The organization is counting on IT to have a plan in place that ensures that business operations will continue in the event of a disaster. Most organizations today have a 99% uptime requirement. This means that data services are available 24 hours a day, 7 days a week, for 99% of the year. Data archiving supports a well-designed disaster recovery plan by moving a copy of the data used in the production environment physically away from the organization’s data operations center to a remote location.
Imagine that your company has two locations—one in hurricane-prone Miami, Florida, and the other in earthquake-prone Los Angeles, California. The company policy is to handle data network storage in-house. The company processes high-volume transactions daily, and the data is considered mission critical.
• Discuss your solution to archiving the company’s data, and be prepared to defend your option versus other students’; proposals.
• Elements of your answer should include the following:
• Hot site versus cold site
• Data mirroring capability
• Tape and optical drive backups
• Offsite data storage services
Grading Criteria:
Your paper should indicate that having an offsite data storage program is essential to supporting the goals of business continuity. The fact that the organization handles all of its data storage in-house is a risk, especially considered the environmental risks of each location.
In an ideal setting, the hot site data mirroring option would be preferred as it would ensure real-time backup of crucial data while also providing the shortest lead time between the system going down and coming back up at the hot site; however, this option is expensive.
A less cost-prohibitive option is the cold site because it does not have operational equipment in it but is a predetermined location for operations to move to in the event of a disaster. The lead time in setting up a cold site would severely effect business operations. Data archiving in the form of backup tapes or optical drive platters provide the data used in cold site recovery as well as day-to-day file recovery. Backup tapes typically contain a full backup performed once a week, with incremental backups done daily.
Assignment 4
You are a respected and tenured IT professor and you also manage the university computer operations that consist of a server farm of 8 servers and an NAS of 100 terabytes. The CIO is excited to announce that the university enrollment is increasing at a steady rate, and as a result, the number of college students enrolling at the university has increased dramatically. This has caused the data requirements to grow 27% in the last 6 months. Your boss at the university has asked you to provide a 2-year plan to address this unprecedented growth. Write a paper of 3–4pages (APA formatted)of your 2-year plan. Include the following: Primary problems that exist in meeting the growth requirement and your proposed solutions A list of common problems that you may encounter while adding storage to meet growing data storage requirements Your proposed solutions…(More)

You have been selected for admission into the Who’s Who in IT Professionals and have been invited to speak at a conference in Las Vegas. As a key note speaker on the topic of “The future of data encoding and compression,” you have been asked to discuss the effect that cheaper storage, higher volume storage, higher bandwidth, and faster processing will have on current methods of data encoding and compression. Your audience will be comprised of both IT and non-IT professionals, so you will need to explain the basic principles of data encoding and compression as well as forecast the future effect that new technologies will have on them.
Please describe and discuss the following in a 5-6 page APA formatted paper:
• What is data encoding?
• What is data compression?
• How do they support today’s data storage needs?
• Forecast if technology advancements in storage, bandwidth, and processing speeds will effect current methods of data encoding and compression.
Grading Criteria:
Data compression: Storing data can take up a lot of space, and this fact creates the next challenge for computer scientists to overcome. Storage media can be expensive, and the ability to have quick access to your data while also having the vast amount of storage space to store all of your data can be a challenge. Computer scientists have addressed this problem by creating a process of compressing data.
Data encoding: Data encoding occurs when a computer storage device takes the electrical signal generated from the creation of data and then converts it to a form that can be stored. To understand this process, you must understand how information is stored on a magnetic storage medium. Of course, there are many mediums in use today, but magnetic is the most commonly used and a good point to begin your understanding of data encoding. Computer data exist in the form of binary 1’s and 0’s that are sent to a magnetic recording head in the system’s hard drive storage medium. The head creates magnetic sectors on the storage device with specific polarities corresponding to the positive and negative that the drive applies to the head. Boundaries are created using flux reversals between the positive and negative polarities that the drive uses to encode the data onto the hard drive platter. This is the process in which data is stored electronically. When the data is retrieved for use, each flux reversal that the drive detects generates a positive or negative pulse that is used to reconstruct the original binary data.
It is reasonable to expect that changes in technology will drive new forms of data encoding and compression, and existing methods will eventually phase out as new methods are introduced. The drive to do more with less is the single thought process behind this change. That is to say, to gain more storage with less of a physical medium that has a smaller energy footprint.
