ISL Trunking: Automatic Traffic Management at the Heart of the SAN

Source: QLogic Corporation
Permanent node-to-node data paths through a service area network (SAN) fabric are surprisingly inefficient. Some interswitch links (ISLs) become oversubscribed, while others are underused, and don’t allow you to maximize the function of your existing switch investments. Unclog your SAN’s data paths—and increase reliability and availability, as well as your return on investment.

Linked Enterprise Data: Principles, Uses, and Benefits
Source: Antidot Over time, as a result of operating pressures, the proliferation of tools, and changing technology, the corporate information system (IS) has become fragmented. Whereas the database formed the heart of the system 20 years ago, today there are countless sources of data: ERP, customer relations systems, sales management, internal directories, intranets, extranets, websites, etc. Yet this huge quantity of data is not being mined for the wealth and scope of its potential by either employees or information system applications, mainly because the data is closed off in an array of silos. Read this white paper to see how linked enterprise data (LED) can help. Read More...
Linked Enterprise Data: Data at the heart of the company
Source: Antidot The data silos of today's business information systems (IS) applications, and the pressure from the current economic climate, globalization, and the Internet make it critical for companies to learn how to manage and extract value from their data. Linked enterprise data (LED) combines the benefits of business intelligence (BI), master data management (MDM), service-oriented architecture (SOA), and search engines to create links among existing data, break down data walls, provide an open, secure, and long-term technological environment, and reduce complexity—read this white paper to find out how.

How Application-aware Networks Make the Impossible Possible
Source: Riverbed Technology Network traffic patterns have dramatically changed from predictable point-to-point transaction-oriented activities to bandwidth-hungry, always-on, many-to-many interactions. A coordinated approach across multiple datacenters and remote locations with actionable metrics is the only way to ensure that the network team will be a trusted partner in the new intelligent economy.

Extending the SAN for SANbox 9000 Core Switches
Source: QLogic Corporation The enterprise environment continues to evolve and change. Regardless of technology breakthroughs and system designs, storage area networks (SANs) continue to provide IT with severe administrative challenges. But by implementing a cost-effective and robust core-to-core solution, system administrators can reduce the management burdens and provide greater access to network resources. Read More...
Zoning: The Key to Flexible SAN Management
Source: QLogic Corporation The days of storage area networks (SANs) built with hubs and based on private, arbitrated loops are gone. Today’s fully public switches—which include a variety of switch features—make managing large SANs a lot easier. The key to a flexible SAN is the switch’s ability to create zones, which allows the SAN to be partitioned into various groupings and enables SAN managers to allocate storage where it makes the most sense.
