Analysis of Server Consolidation in the Data Center: VMware Vs. Virtuozzo 2007-04-01 Parallels (formerly SWsoft)

The reduction of the physical number of servers in a modern-day IT organization, otherwise known as "server consolidation," is of utmost importance to IT managers, who are forced to look for ways to reduce the time and money associated with maintaining their hardware and software. The apparent leader in this emerging field is IBM, with vast experience supporting multiple machine partitions using mainframe technologies. IBM is coupling the Open Source Linux OS with the mainframe in an attempt to push Linux server consolidation onto their zSeries. Sun Microsystems has also entered the server consolidation field with their high-end enterprise servers using a dynamic domain partitioning technology.

Adaptive Control of Virtualized Resources in Utility Computing Environments 2007-03-23 Association for Computing Machinery

Data centers are often under-utilized due to over-provisioning as well as time-varying resource demands of typical enterprise applications. One approach to increase resource utilization is to consolidate applications in a shared infrastructure using virtualization. Meeting application-level Quality of Service (QoS) goals becomes a challenge in a consolidated environment as application resource needs differ. Further-more, for multi-tier applications, the amount of resources needed to achieve their QoS goals might be different at each tier and may also depend on availability of resources in other tiers. This paper develops an adaptive resource control system that dynamically adjusts the resource shares to individual tiers in order to meet application-level QoS goals while achieving high resource utilization in the data center.

Server Virtualization in Autonomic Management of Heterogeneous Workloads 2007-03-23 Technical University of Catalonia

Server virtualization opens up a range of new possibilities for autonomic datacenter management, through the availability of new automation mechanisms that can be exploited to control and monitor tasks running within virtual machines. This offers not only new and more flexible control to the operator using a management console, but also more powerful and flexible autonomic control, through management software that maintains the system in a desired state in the face of changing workload and demand. This paper explores in particular the use of server virtualization technology in the autonomic management of data centers running a heterogeneous mix of workloads. This paper presents a system that manages heterogeneous workloads to their performance goals and demonstrates its effectiveness via real-system experiments and simulation.

RAID 6 Principles: A Deep-Dive Tutorial 2007-03-22 Symantec

SATA hard drives are continuing to assume new roles within enterprise applications. While a hard disk's expected useful life is largely independent of its host controller interface (SATA, FC-AL, SCSI, SAS, etc,), the present conventional perspective is that desktop hard drives have SATA interfaces and enterprise disks have FC-AL, SCSI, or SAS interfaces.

A Pragmatic Approach to Server and Data Center Consolidation 2007-03-12 PlateSpin

This paper provides an overview of the factors driving consolidation initiatives and considers best practices for ensuring a successful consolidation initiative and a maximum return on investment. It also provides an introduction to workload profiling and portability technology which has helped thousands of organizations accelerate their consolidation initiatives and optimize their data centers through continuous server consolidation.

Data Center Sustainability 2007-03-07 Techuities.com

The internet is everywhere. It's not only on the computers, but the mobile phones, televisions and portable music players. Very few users of digital content consider how data arrives on these devices. The digital age is being delivered via massive server farms housed in data centers that are managed by thousands upon thousands of Information Technology (IT) professionals. For a very long time, the only concern for these professionals was to process more data and to do it at a faster rate. Now that density at data centers has reached a tipping point, the issues of power consumption and environment regulation are at the face of the industry.

Managing Data Center Power and Cooling 2007-03-01 Force10 Networks

Managing Data Center Power and Cooling Optimizing the overall power efficiency of the data center requires a comprehensive approach that focuses on technologies and strategies to minimize power consumption and maximize power efficiency at every level within the infrastructure, including CPU chips, power supplies, servers, storage devices, and networking equipment. In addition to measures that maximize power efficiency for hardware devices, there are also software strategies, such as server virtualization, that can play a significant role in reducing power consumption. There are a number of potential benefits that can be derived from an increased focus on power consumption and power efficiency: â¢ Extending the life of existing data centers and minimizing retrofits â¢ Gaining at least partial control of growing expenses for power and cooling â¢ Optimizing new data center designs

Green Grid Metrics: Describing Datacenter Power Efficiency 2007-02-20 Green Grid

The Green Grid is an association of IT professionals seeking to dramatically raise the energy efficiency of datacenters through a series of short-term and long-term proposals. For the short term, The Green Grid is proposing the use of Power Usage Effectiveness (PUE) and Datacenter Efficiency (DCE) metrics, which enable datacenter operators to quickly estimate the energy efficiency of their datacenters, compare the results against other datacenters, and determine if any energy efficiency improvements need to be made. In the long term, The Green Grid is proposing the Datacenter Performance Efficiency (DCPE) metric and a refined version of the PUE metric be adopted for all major power-consuming subsystems in the datacenter.

Guidelines for Energy-Efficient Datacenters 2007-02-16 The Green Grid

Power availability is one of the most important challenges facing datacenters today. In the past, datacenter floor space has always loomed as the primary issue. Now, more and more datacenters run out of power availability before they run out of floor space. In addition, cooling requirements for dense servers are driving power demand and taxing the normal datacenter operational procedures. This paper provides a framework for improving the energy efficiency of both new and existing datacenters. The nature of datacenter energy consumption is reviewed and best practices are suggested that can significantly impact operational efficiencies.

Data Center Consolidation 2007-02-15 Citrix Systems

As both technology and government agency management systems improve, so too does the viability of enterprise-level Data Center Consolidation (DCC). The significant and short-term cost savings, as well as the resulting improvements in information security and cross-agency collaboration, make DCC more attractive than ever. Looking at the major trends in the Federal agency IT environment, it is clear that DCC is at a tipping point, with widespread action imminent in all sectors of government. Although given little attention by most consolidation strategies and enterprise architectures, securely delivering applications and information to users is one of the most critical issues affecting the decision to consolidate.
