Welcome to the Wikibon Performance Lab Portal. The Performance Lab Portal is an IT best practice resource for technology professionals to share best practice on performance-related issues in an effort to architect better business capabilities. This portal was launched by Wikibon in conjunction with Demartek which provides lab validation testing of server, network, storage and security technologies small, medium and large enterprises. We welcome you to actively participate in the portal. You can Ask a Question, Create a Wikitip, Comment on a research note or participate in one of our many Peer Incite Research Meetings.
Latest Performance-related Peer Incites:
1. HP's Tina Rose discusses the results of her testing Oracle remote replication solutions. (1:05:04)
2. HP's Blair Parkhill's discusses how users can reduce Exchange backup windows (1:7:06)

Wikitip
Welcome to the Wikibon Sustainability Portal. In this space we focus on the application of 'Green' technologies to create more energy efficiency IT and business environments. We welcome you to browse the portal, share best practices with peers by writing a Wikitip or joining in a Peer Incite Research Meeting.
The Wikibon Green IT Technology Portal contains green IT industry research, articles, expert opinion, case studies, and green IT technology company profiles.
Latest Green Peer Incites:
1. JCPenney's Drive to Green IT (5:09)
2. The Power Shift to Green Computing. Peter Burris summarizes Wikibon's Peer Incite on Green IT (4:27)

Wikitip
IT organizations have an opportunity to participate actively in energy reduction strategies and must act urgently to quantify the problem, change perceptions and benchmark progress. Construct a plan of attack that includes green metrics. The fact is that storage is only a small part of the problem but embracing this reality will allow organizations to preserve service levels, streamline infrastructure and demonstrate ongoing bottom line financial contribution.

Featured Case Study
Wikibon reviewed the power measurements made on 3PAR’s InServ E200, S400 and S800 storage arrays. These arrays are built from standard components, and enable the power of different configurations to be calculated. The measurements were made at the component level.
The measurements were made across three different workloads:
- Sequential read, with a 512K block size
- Random read, with a 16K block size
- Idle (no data being transferred)
The results of the three workloads were averaged to produce an overall figure of power consumption for each of the components of the 3PAR arrays. Wikibon believes that the benchmarks used and the power measurements made were done professionally and in good faith. In the opinion of Wikibon, this measurement represents a good and reasonable estimate of the power consumed in real world applications across a number of drives for applications typcally found in a data center.

Featured How-To Note
|
Fluctuating energy prices have heightened electricity and energy consumption as a major issue within the technology community. IT is a significant consumer of energy and IT energy costs have been rising disproportionately because of continued investment in denser IT equipment. Estimates from the EPA and others indicate that IT will account for 3% of energy consumption by 2012.

Featured Lab Report
The corporate IT group of a very large, worldwide financial organization with 100,000 employees, has initiated an ongoing “greening” process. This is focused largely on reducing energy use both to decrease the corporation's carbon footprint while creating a net savings in operational costs over the lifetime of new, more energy-efficient equipment, including new storage systems.
