Strategies for ensuring clean, continuous power to essential IT systems
[ Source: Eaton ]
September 2009-
Data centers rely on a continuous supply of clean electricity. However, anything from a subtle power system design flaw to a failure in the electrical grid can easily bring down even the most modern and sophisticated data center.
Fortunately, organizations can significantly mitigate their exposure to power-related downtime by adopting proven changes to their business processes and electrical power system management practices.
This white paper discusses 10 such underutilized best practices for building ....
Energy Logic: Reducing Data Center Energy Consumption by Creating Savings that Cascade Across Systems
[ Source: Emerson Network Power ]
August 2009-
This paper introduces the concept of the “cascade effect” and describes how it can be used to cut data center energy costs by 50% or more. Emerson Network Power came up with this vendor-neutral roadmap for optimizing data center efficiency, called Energy Logic, by applying the top ten energy-saving opportunities to a 5,000-square-foot data center model based on real-world technologies and operating parameters.
Outlining this sequential approach to reducing energy costs, this paper includes ....
Power Monitoring 101: Supervisory, Connectivity and Protection Options That Add An Umbrella of Protection Over Your Entire IT Infrastructure
[ Source: Eaton ]
August 2009-
Monitoring options are now available for organizations of any size. You can remotely monitor and manage a single uninterruptible power system (UPS), an enterprise-wide network of many UPSs and power distribution devices, or a complete IT support infrastructure, including generators, environmental systems and detection devices, and other components from multiple vendors.
This white paper discusses the imperatives of intelligent power monitoring.

August 2009-
ISC Corp., a provider of advanced technology solutions, had been experiencing business growth which prompted the creation of a new data center to support continuous availability for its IT and telephony systems. The company’s goal was also to design and equip its new data center to serve as a dramatic, state-of-the-art sales tool promoting its capabilities as well as those of its technology partners. Emerson Network Power and its Liebert power and cooling technologies was ....
Calculating and Prioritizing Your Data Center IT Efficiency Actions

July 2009-
The lack of a true data center efficiency metric is challenging to IT and data center managers as they try to justify much needed IT investments to management. To help quantify data center efficiency, Emerson Network Power introduces in this paper CUPS, or Compute Units per Second. Similar to miles-per-gallon metric in the automobile industry, CUPS is meant to represent the “performance” of the data center.
Using the Energy Logic analysis and the CUPS-based ....
Focused Cooling Using Cold Aisle Containment

June 2009-
As heat densities and cooling costs rise, data center professionals are looking for more efficient cooling solutions. This paper discusses the benefits of using both the hot and cold aisle approach, but focuses on the latter option as an effective method for eliminating data center hot spots and reducing overall cooling costs by as much as 30%.
Discover how cold aisle containment, as an addition to a conventional precision cooling system, consistently separates ....

January 2008-
This paper describes a case study in which an IBM System Blue Gene Solution supercomputer is configured to natively access General Parallel File System (GPFS) 2.3 file systems that are owned by an IBM eServer pSeries cluster with AIX 5L and the IBM eServer High Performance Switch (eHPS). The IBM System Blue Gene Solution Service Node (SN), Front-End Nodes (FENs), and I/O Nodes (IONs) are configured as one GPFS cluster that does not contain any ....
Optimizing Mirroring Performance Using HACMP/XD for Geographic LVM
[ Source: IBM ]
January 2008-
The mirroring of data between two remote sites has become significantly easier with the arrival of the new HACMP/XD for Geographic Logical Volume Manager (GLVM) solution. As an IP-based solution, GLVM sites can span an almost unlimited distance. In GLVM, the AIX 5L LVM (Logical Volume Manager) itself is responsible for mirroring the data; thus several complex and time consuming manual tasks have been eliminated. The configuration and management of GLVM is therefore simpler and ....

It is clear that from the point of view of theoretical maximum performance, the Cell BE processor’s low-latency local store with bandwidth-efficient DMA and manually managed memory latency offers significant advantages. However, from a software-engineering perspective, the impact of porting some types of legacy game software is daunting. It is not enough to identify computationally expensive sub-processes and fit them onto the SPEs; the data which supports those sub-processes must be stored in a compact ....
