NAS vs. SAN Networks
NAS which in full stands for network attached storage refers to a system which is made up of one or more hard drives, an operating system as well as an internet connection (Troppens & Erkens, 2004). The system links different people on the same network hence can easily share data from a central point. The storage area network on the other hand, refers to a designed network that offers access to amalgamated stored data (Dwivedi, 2006). The SANs network is usually not accessible via the LAN. Similarly, the SAN network (storage area network) is a network that utilizes its protocols such as HBA adapters, SAN switches, SAN controllers and disks among others to store data. The ability to store data in blocks instead of files makes the network store large quantities of data.
Wright technologies, is an IT company with a personnel of 500 employees (Troppens, 2009). On annual basis, the company generates a total of 5billion dollars with a data requirement of $1000 dollars per user per month (Troppens, 2009). Being an information technology a lot of data is used in the maintenance of the databases. An average of $800millionis generated in a month (Troppens, 2009). Time sharing is the most preferred data transaction system used with batch processing also used when required.
In most cases, the company prefers SANs over NAS because of its low latency and the ability as well as its specialized consistency in reading and writing of data (Troppens & Erkens, 2004). When it comes to covering large geographical areas, SANS are handy because they use hubs, routers, switches in creating fiber channel fabrics that accommodate a large number of devices as compared to NAS.
When it comes to carrying out of data operations, unlike the NAS network which can transverse the LAN, the SANS carries out several data operations without trans versing the LAN (Dwivedi, 2006). In this case, there is a higher efficiency in the transmission and dispatching of large amounts of data via the internet and IP. In incidences where the company has several data centers, the SAN network can be essential in the distribution and allowing access to storage assets without relying on the physical location whereas the NAS only allows distribution of data when the users are located at the same point.
Wright technologies are a large enterprise network and in this case, the company requires extremely high speed transfer tasks as well as a lot of terabytes of consolidated and centralized storage systems. Such operations make it completely impractical to use the NAS devices but installation of high performance SAN network increase the much desired scalability and efficiency.
Whereas at times the NAS network may experience incidences of congestion when huge packets of data require backing up during operational hours, the SAN network on the other hand is designed to create a separate network designed to store, backup and restore data without interfering with the normal operation of the IP network.
SAN is very appropriate in the transfer of large and heterogeneous blocks of data. The ability to create low latencies, being highly reliable, lossless and being fast makes the SAN network preferred over NAS especially when transacting demanding databanks such as CRM and ERP systems that require high performance (Troppens & Erkens, 2004).
Conclusion
Whereas the SAN and NAS differ in their functionality and efficiency, it is possible to utilize a combined SAN-NAS hybrid which offers advanced protocols of both file level and block level in a single system. If implemented, Wright technologies can be able to allow her servers boot from the SAN network and also easily replace defective servers because with the hybrid the SAN network can be modified to enable the replaces servers use the LUN of the faulty server (Dwivedi, 2006).

Unit 2 Seminar human services and policies
In the early days, journalism did not concern itself with truth or ethics. This led to inefficiencies in the mass and media communication sector.
How is policy inefficiencies identified?
For instance, in journalism, policies inefficiencies are identified when the news reported have loose credibility. This is by the use of extreme rhetoric extension and misleading reports that affect the viewers and people reading news. Some of the stories issued by journalists are usually one sided and one dimensional. This is an inaccuracy in journalism that can lead to a threat to the true news covered contrary to the objective of media and journalism. Policy inefficiency is also identified when independent reports are lost (Aggarwal, 2002). This is seen when stories are changed and modified frequently without consultations. Additionally, these inefficiencies may be recognized when a journalist isolate an incident of a given politician or organization. This leads to the public believing that the person stated is either good or bad as reported by the media. Economical inefficiencies in journalism are identified when journalists cause limited use of technological, fiscal and human resources.
Identifying a new policy in Journalism
New policies are identified based on how the technology is changing. On the other hand, media growth leads to identification of new policies in media and communication. When there is lack of integrity and self awareness in journalism, policies may be implemented (Wongrujira, 2008).
Correcting the inefficiencies
The media and journalism is supposed to be dependent on the wires for various events and news conferences. Media houses are supposed to delegate their own reporters to look out for more features in a given story. They are not supposed to be one sided and issue untruthful reports. The journalists are also supposed to be appear early in various scenes occurring so that they may cover the whole details needed (Wongrujira, 2008). This will help in correcting inefficiencies seen.

Narrative of the Life of Frederick Douglass
Essentially, slavery is a form of human interaction that seeks to further domination of one party over the other. As such, it deprives the weaker party of a chance to enjoy its freedom accordingly. Numerous studies contend that it literary kills the worth of the person as the masters’ aim at destroying the honor and pride of the slave. Consequently, the slave becomes vulnerable and unable to survive without the help of the master. Of great reference is the fact that the slave is also deprived of his or her liberty and freedom. Slavery had far reaching implications on the holistic wellbeing of slaves in America. Comparatively, it is indicated that American slavery was characterized by a high level of brutality that had never been experienced in the past.
For instance, it is posited that slaves in the Roman Empire were allowed to interact with the families of their masters. Such an instance was not experienced in the American society due to the fact that the same was stratified according to social classes. It is against this disturbing background that his paper reviews the role that violence played in the narrative of Fredrick Douglass. In order to enhance a harmonic consideration, it underscores the extent to which one’s gender determined the Millward Winter 2010 six types of violence that they experienced. Finally, it analyzes the experiences of the slaves in light of Fredrick’s narrative.
Since it was entirely meant to reinforce power and domination, slavery was characterized by a high degree of violence. Arguably, this is fundamental in the creation and maintenance of power and domination. It is notable that slavery was exercised in communities that were highly stratified. As such, the masters employed violence repeatedly in order to prevent the reduction of the numbers of slaves through freedom and/ or death. Further, Douglass (2001) indicates that violence was also employed to encourage the slaves to work and produce more. In this regard, it is indicated that the slaves worked harder in order to avoid the punishment that was associated with laziness. In addition, violence during slavery was instrumental in maintaining the stratified conditions between the masters and the servants. As such, Nudelman (2003) argues that there was no mingling and that slaves found interacting with the White population were punished accordingly. In this case therefore, violence was a critical tool in preventing the slaves from maintaining a close relationship with their White masters. Violence was also employed in destroying the existing social ties that the slaves had. As indicated earlier, this culminated in a condition of increased vulnerability and dependence on the master for survival.
Notably, violence was accorded a gendered approach and women had different experiences from their male counterparts. Comparatively, women experienced different forms of violence that had diverse effects on their wellbeing than their male counterparts. Thus gender played a critical role in determining the kinds of violent episodes that each segment of the population experienced.
Fredrick’s narrative brings to the light the various inhuman conditions that characterized slavery. He cites that they were traded for money and other resources. In this respect, Horton and Lois (2006) assert that their human worth was reduced to that of goods that could be easily exchanged for cash. This had negative implications on their psychological wellbeing as they were uncertain of the time that they could be sold. Basically, selling implied that they could no longer stay with their families. Historical evidence points out that slaves were sold for various reasons.
To begin with, those who worked in the plantations were commonly sold in instances where they became troublesome. In such cases, their masters considered them a threat to the overall economic production and social wellbeing. At this point in time, it should be appreciated that the plantation owners controlled the economy and politics of the region. This was made possible through increased economic production. Thus any activity that could affect production was not compromised. Also slaves were usually sold when their masters died. In his review, studies ascertain that the death of a master or slave owner led to the breaking up of his estate. Further, Harden (2003) reports that the masters often sold the slaves in order to get a chance to sexually exploit the wives of the slaves. Selling of slaves had adverse effects as it led to breaking up of families and important social ties as they never saw their relatives again.
In some instances, they were also hired in exchange for cash. Harden (2003) shows that this was particularly common with the slaves that resided in the urban areas. The urban economy was characterized by commercial activities that did not require a lot of slave labor. While it is indicated that in most cases the slaves were hired by the owners, Douglass (2001) notes that slaves leading desperate lives could hire themselves out through vendors.
In his narrative, Douglass (2001) confirms that slaves were generally exposed to brutal treatment. This was characterized by physical assault, torture, threats, intimidation and sexual exploitation. They were expected to adhere to the conditions laid down by their masters. Any form of disobedience of the White population immediately led to brutal retaliation. Further, some laws were put in place to prevent the saves from utilizing their property in the ways that they deemed important. At this juncture, it is worth noting that slavery undermined the holistic freedom of the slaves. Various methods were employed in punishing the slaves, in line with the severity of the offense. Common methods according to Douglass (2001) included slitting tongues, breaking legs, and boxing ears, severing fingers and mutilating the body. Furthermore, cuts with a stick and verbal abuse were also employed during punishment. However, the most popular method that was employed in punishing the slaves was severe whipping. In this consideration, it can be ascertained that the punishment that was administered to the slaves left them with permanent emotional and physical scars.
Conclusion
Slavery is a social ill that greatly undermined the human worth of the slaves by depriving them of fundamental freedom and liberty. It was a form of domination and power that was characterized by a great degree of violence. In particular, the physical assault that violent punishment inflicted on the slaves had adverse emotional effects. From the review, it is clear that violence was employed for various reasons that ranged from increasing productivity to denying the slaves the fundamental freedom. The experience that the slaves dreaded most was their being sold. This is due to the fact that it broke their family ties and encouraged sexual exploitation of the enslaved women. It is in this consideration that this paper concludes by ascertaining that slavery and violence exposed the slaves to inhuman conditions and greatly undermined their holistic wellbeing.
