Raid Research Essay Example for Free

Raid Research Essay The word RAID stands for redundant ray of independent disks. Raid is usually used in environments with servers or at a business with large file servers, transaction of application servers, where data accessibility is critical, and fault tolerance is required. There are 8 types of raids, Raid 0 is technically not a raid level because it offers no fault tolerance but, it operates by providing data stripping which takes the information and spreads it out over all the disk drives. However, if one drive fails than the entire raid fails. Raid 1 is also referred to as disk mirroring; it basically takes the information from one disk and stores it on multiple disks, this is great for fault tolerance because if one disk fails the information is on another disk. The only drawback to raid 1 is data access speed and the cost because there are more disks involved. Raid 5 is considerably the most commonly used Raid level simply because it provides both stripping and parity. The parity block is distributed to all of the drives making it easier to access the information or have a balanced access load. The parity in raid 5 is used if one of the drives happens to fail, to recover that drive which makes the raid 5 the most common however the only drawback to this raid level is that it has a relatively slow write cycle. Lastly, RAID level 6 which is very similar to raid level 5 but provides two parity functions rather than just one. A minimum of four disks is required to create RAID level 6. Raid level 0, even though it offers no redundancy, is still of use mainly to those who use applications that require high bandwidth such as data streaming or video editing software. Raid level 0 is also used because it’s most simple to implement. Raid level 1 is most expensive because it requires more disks to implement. It also requires heavy software manipulation and configuration to implement Raid level 1. If I were to purchase raid it would absolutely be raid level 0 simply because its easy to implement and it would be efficient for my personal usage.

The Impact Of The Enlightenment On The Colonies :: American History

The intellectual current known as the Enlightenment deeply affected the learned clergymen who headed colonial colleges and their students. Around 1650, some European thinkers began to analyze nature in order to determine the laws governing the universe. They employed experimentation and abstract reasoning to discover general principles behind phenomena such as the motions of planets and stars, the behavior of falling objects, and the characteristics of light and sound. Above, all Enlightenment philosophers emphasized acquiring knowledge through reason, taking particular delight challenging previously unquestioned assumptions. John Lockes Essay Concerning Human Understanding disputed the notion that human beings are born already imprinted with innate ideas. All knowledge, locke asserted, derives form ones observations of the external world. Belief in witchcraft and astrology, among other similar phenomena, thus came under attack. The Enlightenment had an enormous impact on educated, well to do people in Europe and America. It supplied them with a common vocabulary and a unified view of the world, one that insisted that the enlightened 18th century was better, and wiser, than all previous ages. It joined them in a common endeavor, the effort to make sense of God's orderly creation. Thus American naturalists like John and William Bartram supplied European scientists with information about New World plants and animals so that they could be included in newly formulated universal classification systems. Americans interested in astronomy took part in an international effort to learn about the solar system by studying a rare occurrence, the transit of Venus across the face of the sun in 1769. An example of the Americans participation in the Enlightenment was Benjamin Franklin, who retired from a successful printing business himself to scientific experimentation and public service. His experiments and observation on electricity established the terminology and basic theory of electricity still used today. The experimentation encouraged by the Enlightenment affected the lives of ordinary Americans most dramatically through advances in medicine specifically, the control of smallpox. The Reverend Cotton Mather, the prominent Puritan cleric, learned from his African born slave about the benefits of inoculation (deliberately infecting a person with a mild case of a disease) as a protects against smallpox. When Boston in 1720-1721 suffered a major small pox epidemic, Mather urged the adoption of inoculation despite fierce opposition from the cities leading physician. Mortality rates eventually supported Mather- of those inoculated, just 3 percent died; of other 15 percent.

Booker T Washington

Booker T. Washington and the Struggle Against White Supremacy One of the most powerful black leaders to have ever live, this is what some people argued of Booker T. Washington. With a black mother and white father he never knew, Washington was born into slavery near Hale’s Ford in Franklin County, Virginia. He worked growing up, and then attended Hampton Institute, a school designed to educate African and Native Americans. I don’t think he knew, that anybody knew, how much he would change the world over his lifetime. There were many racists view’s back then.Booker T. Washington learned how to work around whites to get what he wanted, and took many tours around the United States to teach other blacks. Racism has been around for years, and remains around today. The difference is that it was much more cruel back then. There were many racist views expressed by whites toward blacks in the 19th century. After Reconstruction, whites began to really express these views. They had seen that blacks had been involved in many black political activities and it pissed them off. They also were mad since they had lost the Civil War.They claimed that: â€Å"Blacks had had their fair chance, had demonstrated their present incapacity for self-government, and could justifiably be relegated, for time being at least, to an inferior status. † Black people where humiliated, beaten, and thrown in jail, and even killed. Whites also controlled blacks’ futures economically. They established black codes to ensure that blacks had stable labor force, which designated â€Å"servants† as employees and â€Å"masters† as employers. This prevented blacks from vagrancy or loitering, making them work even if they did not want to. Booker T.Washington was a very smart man, well at least I think he is. He knew how to get what he wanted, the psychology of â€Å"Black Survivalism†. He uses many survivalist tactics he used on white people to gain imp roved living conditions for blacks. Many people feel that he was a sellout, he was, but it gained from it. Washington believed that black people’s problems would be solved if they worked like whites needed. If they would abide by the law and cooperate, the industrial education would provide them with an economic niche. Eventually, he believed this would lead to economic independence.Of course, white people thought that Washington was trying to promote segregation and black inferiority. He was not trying to promote segregation, but he was going for black inferiority. Black people needed to do this. Washington was basically saying that if black people continued to work in their field, and other fields, they had the upper hand. They would learn all the techniques, and know everything about that field. Whites did not work, so they knew nothing. Without the blacks, they could not make any money. Booker T. Washington took many tours.The tour that I was most interested in was his to ur of Florida. This caught my attention I live here in Florida. This is apart of its history. Washington started his tour of Florida on March 1, 1912. It lasted from March 1st til March 7th. His tour was sponsored by The Florida State Negro Business League. FSNBL was made up of businessmen and women who believed that they could form a â€Å"good strong organization† that would â€Å"benefit and up build the colored race†. They accomplished exactly what they wanted. Booker T. Washington’s first stop on the was Pensacola.Pensacola was the home of Matthew Lewey, the publisher of the first black newspaper in Florida, the Florida Sentinel. This was not only Lewey’s home though, it was mine also. I lived in Pensacola most of my life before moving to Tallahassee. A Negro business community, is what Washington had called Pensacola in 1907. To him it represented â€Å" that healthy progressive communal spirit, so necessary to our people†¦Ã¢â‚¬  By 1910, the city had declined from their â€Å"black progress and success†. Yet, here he was making his first stop here five years later. March 1, 1912 he spoke at the Opera House in Pensacola.His speech was heard by over two thousand people. There were eight hundred whites in attendance, the rest were black. In his speech he gave encouragement and moral advice. Saying: â€Å"We not only have the advantage in a state like Florida of securing land, but the further advantages of finding plenty of work,†¦Ã¢â‚¬  â€Å"There are few if any members of our race who have spent any considerable length of time in seeking labor, labor seeks them. Our condition is different from laboring people in many parts of the old world where they have to spend days and sometimes months in seeking labor and then are not able to find it. Washington left Pensacola for Tallahassee. He made a quick stop in Quincy to visit the Dunbar Graded School. When he arrived in Tallahassee he was greeted with a parade . This parade was led by the FAMC band. FAMC is now Florida Agricultural and Mechanical University. The band is now known as the Marching 100. Reading about my school in this book made me even more proud to be a rattler. The parade also consisted of black artisans, professional men, and farmers. Washington gave his speech on â€Å"Some of the Essential Things In Race Development†.Afterwards he was invited to FAMC for a formal reception. Washington then gave another encouraging speech. He complemented FAMC, saying: â€Å"the State of Florida†¦has provided for the Negros in this state the best plant with the best equipment of any state in the Union. † â€Å"I am glad to add that it is the best kept up plant, the cleanest, and the most systematically arranged of any that I have ever seen. † Booker T. Washington visited Lake City, Ocala, Tampa, Lakeland, Eatonville, Palatka, Daytona Beach, and finished his tour in Jacksonville on March 7, 1912. Booker T Washington Booker T.
