Storage Networking , Part 1 eBook: A storage network is any network that's designed to transport block-level storage protocols. But understanding the ins and outs of networked storage takes you deep into several of protocols. This guide covers SANs, Fibre Channels, Disk Arrays, Fabric, and IP Storage.
»Storage Networking 2, Configuration and Planning eBook: Picking up where Part 1 left off, Part 2 of our look at storage networking examines configurations for SAN-attached servers and disk arrays, and also includes a look at the future of IP storage.
»Storage Management Costs in the Enterprise: A Comparison of Mid-Range Array Solutions Whitepaper:
Many factors contribute to the ownership cost for enterprise storage. These include (but are not limited to): physical capacity relative to physical space requirements, performance capacity for data transfer and system reaction time, software maintenance and updates, expandability and flexibility, and much more.
»Storage Is Changing Fast Be Ready or Be Left Behind PDF: The storage landscape is headed for dramatic change, thanks to new technologies like Fibre Channel over Ethernet (FCoE), pNFS, object-based storage and SAS that will affect everything from NAS and SANs to disk drives. Get the knowledge you need to make the most of your storage environment, now and in the future.

JXTA-based P2P Toolkit Enables Utility Computing
September 17, 2002
By Paul Shread
A JXTA-based P2P toolkit for managing compute power like electricity is the latest release from the Gridbus Project.
The Compute Power Market (CPM) Project uses an economics approach for managing computational resource consumers and providers around the world in peer-to-peer computing style, the project said. It allows application users to access computing power with the ease and simplicity of accessing electric power from a wall socket, the group said, and allows consumers to choose computing power and resource providers that offer cost-effective service on demand, "thus creating a competitive market approach to service-oriented P2P computing."
The CPM Project Team@JXTA - Rajkumar Buyya, Fazilah Haron and Chan Huah Yong of the University of Melbourne and Universiti Sains Malaysia - noted that P2P computing applications such as SETI@Home have been developed as vertically integrated, application-specific solutions, which means that distributed applications need to be constructed on a case-by-case basis. To overcome that limitation, Sun Microsystems developed the JXTA generic peer-to-peer protocol, they said. The JXTA technology can be used to develop secure high-level services and applications for file sharing, collaborative applications and distributed computing, among other uses.
The CPM team was formed to develop distributed computing services using a computational economy framework. The collaboration was launched in early 2001 to apply Grid economies architecture developed at Monash University for peer-to-peer computing. The Compute Power Market development activities are hosted through the Sun's JXTA initiative. The CPM technologies enable the creation of market-maker, which brings together a consumer and supplier, the team said.
CPM consists of two actors, provider and consumer, and follows layered architecture. A secure P2P protocol layer is provided by JXTA services. Generic components make use of JXTA services to discover peers and join peer groups based on a market concept. A CPM core engine consists of market, accounting, job management, and trader, and an application programming layer is included. In the application/presentation layer, the team built one simple GUI on top of these services to allow users (consumers) to submit Java class or .exe files to run remotely on a producer peer. Consumers and providers discover and select which market to join. Providers can publish resources that they are willing to trade. Consumers input their cost and deadline and submit the task to the matched provider.
Some documentation is available at http://grid.cs.usm.my/cpm.htm. The project has been carried out through an IRPA grant by the Malaysian Government (for the USM team), and a Sun Microsystems Academic grant (for the Melbourne team).
