The document discusses solid state drives (SSDs) and their benefits over traditional hard disk drives (HDDs). SSDs offer much faster read/write speeds and lower power consumption compared to HDDs. A mixed configuration using both SSDs and HDDs is typically recommended, with "hot" frequently accessed data stored on SSDs and "cold" infrequently accessed data stored on HDDs. The document provides examples of workloads and applications that are good fits for SSDs, and also discusses technologies used in SSDs like single-level cells and multi-level cells. It also covers how to identify and move hot data to SSDs for the AIX and IBM i operating systems.
Purchasing chassis with large numbers of HDDs is one way to configure your infrastructure, but such a solution can provide less than optimal performance, take up a large amount of prime data center space, and increase power and cooling costs. Configuring your servers with SSDs, on the other hand, can dramatically improve performance while simultaneously reducing the overall power consumption of your data center.
In our tests, replacing 24 HDDs in an external chassis with only six internal Kingston SSDs boosted total database performance by as much as 91.8 percent. Not only did the server with Kingston SSDs outperform the HDD solution, it also consumed 32.5 percent less power while active and 51.0 percent less power when idle. Such dramatic performance increases and reduction in power consumption can make Kingston SSDs a compelling choice for the database servers in your data center.

An Active and Hybrid Storage System for Data-intensive ApplicationsXiao Qin
Since large-scale and data-intensive applications have been widely deployed, there is a growing demand for high-performance storage systems to support data-intensive applications. Compared with traditional storage systems, next-generation systems will embrace dedicated processor to reduce computational load of host machines and will have hybrid combinations of different storage devices. We present a new architecture of active storage system, which leverage the computational power of the dedicated processor, and show how it utilizes the multi-core processor and offloads the computation from the host machine. We then solve the challenge of applying the active storage node to cooperate with the other nodes in the cluster environment by design a pipeline-parallel processing pattern and report the effectiveness of the mechanism. In order to evaluate the design, an open-source bioinformatics application is extended based on the pipeline-parallel mechanism. We also explore the hybrid configuration of storage devices within the active storage. The advent of flash-memory-based solid state disk has become a critical role in revolutionizing the storage world. However, instead of simply replacing the traditional magnetic hard disk with the solid state disk, researchers believe that finding a complementary approach to corporate both of them is more challenging and attractive. Thus, we propose a hybrid combination of different types of disk drives for our active storage system. An simulator is designed and implemented to verify the new configuration. In summary, this dissertation explores the idea of active storage, an emerging new storage configuration, in terms of the architecture and design, the parallel processing capability, the cooperation of other machines in cluster computing environment, and the new disk configuration, the hybrid combination of different types of disk drives.

Background: Applied epidemiologists are increasingly working in areas of insecurity and active conflict to define the health risks, suggest feasible means to reduce these risks and, monitor the capacity and reconstruction of the public health system. In 2001, The Carter Center and the United States Institute for Peace sponsored a conference within which "Violence and Health" was discussed and a working group on applied epidemiology formed. The group was tasked to describe the skills that are essential to effective functioning in these settings and thereby provide guidance to the applied epidemiology training programs.
Methods: We conducted a literature review and consultation of a convenience sample of practitioners of applied epidemiology with experience in conflict areas.
Results and conclusions: The health programs designed to prevent and mitigate conflict are in their early stages of implementation and the evaluation measures for success are still being defined. The practice of epidemiology in conflict must occur within a larger humanitarian and political context to be effective. The skills required extend beyond the normal epidemiological training that focuses on the valid collection and interpretation of data and fall into two general categories: (1) Conducting a thorough assessment of the conflict setting in order to design more effective public health action in conflict settings, and (2) Communicating effectively to guide health program implementation, to advocate for needed policy changes and to facilitate interagency coordination. These are described and illustrated using examples from different countries.

LESSONS LEARNED FROM PAST NOTABLE DISASTERS: FLOODING. For centuries, china has enperienced record flooding associated with the rainey season or typhoons. Impacts of flooding in china during 2007: Floods alone killed more than 1,348 people in China during 2007. Economic losses from floods reached more than $10 billion USD. An estimated 139 million people were adversely affected by floods. As many as 2.7 million were evacuated in advance of a single potential flood event.

The Carlton Complex Fire, a massive, lightning-caused wildfire in Washington State, is still out of control, burning houses, and forcing residents of Washington state and Canada to evacuate. The current situation: Gov. Jay Inslee said about 50 fires were burning in Washington, which has been wracked by hot, dry weather, gusting winds and lightning. Some 2,000 firefighters were working in the eastern part of the state, with about a dozen helicopters from the Department of Natural Resources and the National Guard.
The challenges facing the 21st century workforce seem overwhelming. The competition for jobs increases as aging populations remain in the workforce longer, and technology The U.S. is experiencing a disturbing trend in youth losing interest in Science, Technology, Engineering, and Math (STEM). Manufacturing centers locally have suffered from this decline. You might ask yourself, “How do I get youth excited and prepared for the workforce under such bleak conditions?” Heidi Dusek developed/adapted a series of curricula to excite youth about STEM careers while infusing youth leadership qualities that employers are looking for.
In collaboration with many sectors of the community (including school districts, higher-education, and businesses) the Summer STEM academies of 2010 engaged and exposed 42 youth and additional 90 parents and community members. The STEM academies of 2010 included The Magic of Hogwarts, Gateway Academy, CSI: Crime Scene Investigators, and Robotic Rule. Each camp was 2-5 days in length, engaged youth in hands-on opportunities to learn specific career skills and pathways to be successful in the 21st century workforce. All camps included an open house where the youth showcased what they learn through demonstrations and presentations.
The Summer STEM academies proved to be extremely successful by youth, parents, and community partners. Don’t feel like you know enough about STEM? No worries…This session will provide you with tons of resources to utilize in your county including marketing materials, curricula, and evaluation templates. Not to mention we will sample some of the activities so you can be engaged in the process. This is a great opportunity to engage youth and businesses in the same atmosphere for an incredible outcome: a competitive local workforce.
