Best practices for cata centers: Lessons learned from benchmarking 22
data centers
By Greenberg, S., Mills, E., Tschudient, E., Rumsey, P., & Myatt, B.
The energy used by a typical rack of state-of-the art servers, drawing 20 kilowatts of power at 10 cents per kWh, uses more that $17,000 per year in electricity. Given that data centers
can hold hundreds of such racks, they constitute a very energy-intensive building type.

A scalable, commodity data center network architecture
By Al-Fares, M., Loukissas, A., & Vahdat, A.
Today's data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring tremendous cost. Non-uniform bandwidth among data center nodes complicates application design and limits overall system performance.

Server-storage virtualization: Integration and load balancing in data centers
By Singh, A., Korupolu, M., & Mohapatra, D.
With increasing scale and complexity of modern enterprise data centers, administrators are being forced to rethink the design of their data centers. In a traditional data center, application computation and application data are tied to specific servers and storage subsystems that are often over-provisioned to deal with workload surges and unexpected failures. Such configuration rigidity makes data centers expensive to maintainwith wasted energy and floor space, low resource utilizationsand significant management overheads.

Choice and chance: A conceptual model of paths to information security compromise
By Ransbotham, S. & Mitra, S.
No longer the exclusive domain of technology experts, information security is now a management issue. Through a grounded approach using interviews, observations, and secondary data, we advance a model of the information security compromise process from the perspective of the attacked organization. We distinguish between deliberate and opportunistic paths of compromise through the Internet, labeled choice and chance, and include the role of countermeasures, the Internet presence of the firm, and the attractiveness of the firm for information security compromise.

Dear Valued Customer;
Welcome to another edition of our monthly E-Newsletter. Your single source for information associated with the wire-line & wireless communications services industries.
Continuing from the previous edition of best practices and trends, we further explore current data center research in optimized energy consumption architecture, scalable network design, storage virtualization, and information security management. What emerge from the research papers presented in this issue are proposals to manage risks and to contain rising data center cost in the midst of ever increasing complexity and sophistication of the information network.
Greenberg, Mills, Tschudi et al. argued that the key to energy efficient design was effective air management through the use of high efficiency configuration and appropriate power equipment. Al-Fares, Loukissas, & Vahdat proposed a low cost solution to the bottleneck challenge using a novel commodity ethernet switching framework. Singh, Korupolu, & Mohapatra developed a new approach to multidimensional end-to-end network resource management. Ransbotham & Mitra examined both attack motivation model and security countermeasures in the context of information technology crime.
With rapid advances in knowledge by both information technogy researchers and practitioners, ANS constantly strives to provide added value to our customers through shared knowledge, specialized expertise, and continual service improvement.
Our representatives will be at the Data Center World Conference & Expo Spring in Nashville, Tennessee from March 7, 2010 to March 11, 2010. Data Center World is the largest educational conference for data center professionals. If you would like to set up a one-on-one meeting with us at the event, please feel free to arrange a it through DealCenter. Should you have any question, please do not hesitate to contact us at: telecommunicationstimes@anscorporate.com.
