Mass memory systems serve computer needs in both archival and backup needs. There exist numerous applications in both the commercial and military sectors that require data storage with huge capacity, high data rates and fast access. To address such needs 3-D optical memories have been proposed. Since the data are stored in volume, they are capable of much higher storage densities than existing 2-D memory systems. In addition this memory system has the potential for parallel access. Instead of writing or reading a sequence of bits at each time, ....etc

A storage area network (SAN) is defined as a set of interconnected devices (for example, disks and tapes) and servers that are connected to a common communication and data transfer infrastructure such as Fibre Channel. The common communication and data transfer mechanism for a given deployment is commonly known as the storage fabric. The purpose of the SAN is to allow multiple servers access to a pool of storage in which any server can potentially access any storage unit. Clearly in this environment, management plays a large role ....etc

Internet SCSI (iSCSI) is a draft standard protocol for encapsulating SCSI command into TCP/IP packets and enabling I/O block data transport over IP networks. iSCSI can be used to build IP-based SANs.

The simple, yet powerful technology can help provide a high-speed, low-cost, long-distance storage solution for Web sites, service providers, enterprises and other organizations. iSCSI SANs are most suitable for organizations with a need for streaming data and/or large amounts of data to store and transmit over the network.

iSCSI represents ....etc

In the future, the current method of magnetically storing data may reach its limit of maximum achievable density. Hence we need a data storage technology which has high storage capacity and is small in size. The solution is Thermomechanical data storage. Thermomechanical Data Storage is a data storage scheme in which nanometer sized pits on a plastic disc represent digital data. This data storage concept combines ultrahigh density, terabit capacity, small form factor and high data rates. By using this concept, we will be able to store the equiv ....etc

Information Technology (IT) departments are looking for cost-effective storage solutions that can offer performance, scalability, and reliability. As users on the network increase and the amounts of data generated multiply, the need for an optimized storage solution becomes essential. Network Attached Storage (NAS) is becoming a critical technology in this environment.

The benefit of NAS over the older Direct Attached Storage (DAS) technology is that it separates servers and storage, resulting in reduced costs and easier implemen ....etc

The growth in demand for digital storage capacity exceeds 60% per annum. Facilities such as storage area networks, data warehouses, supercomputers and e-commerce, e- related data mining, require ever greater capacity in order to handle the volume of data to be processed.

In addition, with the advent of high bandwidth Internet and data-intensive applications such as high-definition TV (HDTV) and video and music on-demand, even smaller devices such as personal VCRs, PDAs, mobile phones, etc., will, in the next couple of years, demand multi-gi ....etc

A recent innovation in electrical energy storage is the use of flywheel energy storage, also called flywheel power storage. A typical system consists of a massive flywheel disc suspended by magnetic bearings inside a vacuum chamber to reduce friction, connected to a combination electric motor/electric generator. The wheels are generally made of high-tensile-strength fibers (such as carbon fibers) embedded in epoxy resins, or some other high-strength composite material. The system stores power by driving the motor to increase the speed of the sp ....etc

Pumped hydroelectric and compressed air energy storage (CAES) are currently economic for utilities when relying on natural geologic formations and the cheapest, most abundant substances (i.e. elevated water and compressed air). In these situations the cost of energy storage capacity can be very low (<$5/kWh1) Unfortunately the scale and location-specific nature of energy storage in natural formations is likely to render it of limited benefit to small scale distributed renewables. Available pumped hydro and CAES capacities could prove small in r ....etc
