In-band or out-of-band SAN appliances Essay Example for Free

In-band or out-of-band SAN appliances Essay Out-of band SAN appliances allow for independent flow of data between servers and storages since it does not function within the data path (InfoWorld, 2001). In addition, execution of management functions by these appliances is independent of application servers, a factor which dictates for having host drives. This has the implication that the positioning of an out-band SAN appliance posses performance concerns in the system (InfoWorld, 2001). Another implication is that increase in the number of server in such a system complicates administration issues. Still, out-of band SAN appliances have its meta-data and control operations separate from the data path. This coupled with the need for having a driver at each host frees the host to engage only in transferring data to and from the storage. Nevertheless, this configuration has the advantage of caching due to the request time delays involved in linking data path information and the appliance for processing. On the other hand, in-band SAN appliances employ a single device for executing all the basic storage management functions namely; data path, control operations, and meta-data management (Kornfeld, 2001). This has the implication that no additional driver software is needed in the host. Also, this enhances scalability of the SAN system. However, this limits the application of in-band SAN appliances in a busy SAN since both meta-data and control operations share the same data path. Despite this, in-band SAN appliances enjoy the privilege of allowing for caching and clustering (InfoWorld, 2001). In addition, being a single device, in-band SAN appliances boast of low cost of implementation and ease of administration (Kornfeld, 2001). Therefore, both in-band and out-of-band SAN appliances have advantages as well as disadvantages. Considerations before choice of a SAN appliance should thus be based on the needs in the particular organization.

Genetic Engineering Should Not be Banned Essay examples -- Argumentati

Genetic Engineering Should Not be Banned Genetic engineering is a hotly-debated topic. On the one hand, giant corporations, ambitious scientists and powerful politicians are pushing forward with projects they claim will benefit mankind, and on the other, public opinion, environmentalists and consumers' associations are concerned that these projects are insufficiently safeguarded and pose irreversible risks to life on this planet. In this paper I will set out the main issues in the debate on genetic engineering. First I will summarise the history of genetic science, and look at the origins of the debate. Then I will discuss the manipulation of plant, animal and human genes in turn, and consider the possible benefits and dangers of each. Finally, I will suggest that, for all its potential dangers, it is better for research to go ahead openly than for governments to try to ban such research altogether. GE is quite a recent science. DNA, the basic material that determines genes, was discovered in 1953 (the discovery was announced in Nature magazine on April 25th, 1953), and 'It was only in 1956...that cytogeneticists learned that each human cell contains 46 chromosomes' (Lipkin and Rowley, p. 4). 'Recombinant DNA' - which makes it possible to actually change or modify genes - was not discovered until 1973 (Howard and Rifkin, p. 13). However, the debate about GE goes back much further. It was first popularised by Aldous Huxley in his novel Brave New World (1932), in which humans are born in bottles ('test tube babies'), and genetically conditioned to think and behave in certain ways. When GE became a scientific reality in the 1970s, the debate continued to focus largely on the mainulation of human ... ...al groups.
