Local Temperature Control in Data Center Cooling: Part II, Statistical Analysis
[ Source: Hewlett-Packard ]
January 2008-
The data center plays a more important role with the increasing demands of internet and commodity computing. Mechanical engineers face challenges in cooling system design. Recent research focuses on local control algorithms which helps optimize local temperature distribution, and thus increase the energy efficiency of the system. This white paper from Hewlett-Packard analyzes the relationship between rack inlet temperature and vent group configuration from the view of statistics. It also examines whether rack power can ....

Server virtualization offers several benefits including better total cost of ownership, increased operational efficiencies and more flexible management capabilities. But server virtualization may also increase security risks. Virtual machines (VMs) themselves are no less secure than their physical counterparts, but organizations often apply different procedures to their deployment and management. In addition, server virtualization while ....

Storage Networking Case Study: How Cisco Migrated to a SAN Environment in Small European Data Center. Direct-attached storage costs were growing out of control in the Cisco Amsterdam site, which hosts all Cisco IT production applications and some development and staging environments in Europe, the Middle East, and Africa (EMEA). Storage utilization was poor, and management information scarce and hard to come by at the Amsterdam location.

Is Power Your Weakest Link in Data Center Flexibility?: Key Considerations for Power Systems in Adaptive IT Environments
[ Source: Eaton ]
September 2008-
Your IT, networking and telecom systems consume more power than ever. A typical rack or wiring closet of equipment used to consume about 1.7 kW or 2 kW. A few years ago, that would have been high; it would be minimal today. For example, a rack full of Cisco Catalyst 6513 networking equipment consumes 8 kW. A rack of HP Proliant DL145 1U servers consumes 12 kW. Fill that rack with HP blade systems, and ....
