As the Internet and related activities continue to expand, the amount of data that needs to be stored is also increasing. Enterprises and other organizations require effective ways to store and maintain this data. In recent years, many enterprises have seen a significant increase in the volume of data produced. And, this amount of data […]

The emergence of network transports has given rise to new applications and services that take advantage of low-overhead access to the network interface from user or kernel address space; remote direct memory access (RDMA); transport protocol offloading; and, hardware support for event notification and delivery. The Direct Access File System (DAFS) is a new commercial […]

The explosive growth of the Internet and enterprise business applications is placing tremendous demands on global enterprise and service provider networks. Mission-critical applications such as e-business, customer relationship management, storage networking, and emerging applications such as streaming media, are affecting all parts of the network from access to metropolitan- (MANs) and wide-area networks (WANs). These […]

Most of the attention on SANs has focused on the performance benefits of a dedicated gigabit network that relieves conventional LANs of data movement loads. But, from a more holistic perspective, SANs will provide other significant advantages such as improved storage implementation, manageability, more reliable and flexible backup operations, and shared storage resources among multiple […]

The Internet revolution has changed the way business is conducted around the globe. The most significant revenue opportunities available to enterprises today are enabled by e-commerce and e-business. Implementing storage area network (SAN) hosted database applications effectively allows an organization to realize tremendous return on investment by achieving competitive advantage, process efficiency and organizational streamlining.

Storage Area Networks (SANs) have definite measurable benefits over direct attached storage (DAS) as previously discussed in Part I of this article. They also carry additional costs over DAS as well. These costs include additional capital (SAN hardware, SAN software, Redundant Array of Independent (or Inexpensive) Disks (RAID) hardware and RAID software) and additional operating […]

Today, many enterprises that are currently working in a direct attached storage (DAS) environment, are investigating advanced storage options and implementation plans to move to the centrally pooled storage arena by creating and deploying their first storage area network (SAN). Storage area network (SAN) technology provides a variety of business and technical advantages over DAS […]
