iSCSI which became an official standard in February of 2003, links data storage devices over an IP network and is perhaps just beginning to emerge as a serious contender in the storage industry. Why hasn't iSCSI lived up to its early hype? Who is using it today? And, most importantly, what does the future hold for iSCSI?

Getting Started: Understanding The Terminology

Storage Area Network

Storage Area Network (SAN) is a high-speed sub network of shared storage device which contains a disk or disks for storing data. In this architect ....etc

Loop magnetic couplers

Couplers, also known as isolators because they electrically isolate as well as transmit data, are widely used in industrial and factory networks, instruments, and telecommunications. Every one knows the problems with optocouplers. They take up a lot of space, are slow, optocouplers age and their temperature range is quite limited. For years, optical couplers were the only option. Over the years, most of the components used to build instrumentation circuits have become ever ....etc

Open loop control vs. closed loop (feedback) control



The next two figures present the structures of open loop and feedback control systems.
Figure 1 shows an open loop control system whose function is to cause the output y(t) to follow the
reference r(t).
Feedback control system design for zero steady state error
In general, to follow a reference R(s) with zero steady-state error, the path between the
reference and the system output should contain a term like R(s). For instance, to follow a ramp
(velocity ....etc

An industrial plant has hundreds or even thousands of control loops. The performance of control loops is important to ensure high product quality and low cost of the product in such plants. In general, oscillatory variables are one of the main causes for poor performance of control loops. Therefore, detection and diagnosis of the causes of oscillations in control loops is very vital for maintaining the product within the desired quality limits. Identification of such source signatures is a very important task in assessing closed loop control pe ....etc

Every one knows the problems with optocouplers. They take up a lot of space, are slow, optocouplers age and their temperature range is quite limited. For years, optical couplers were the only option.

Abstract

In this study, we propose some simple but effective throughput-approximation methods for finite-buffered closed-loop production systems with unreliable machines and exponentially distributed processing times. The proposed approximation methods are based on decomposition and aggregation principles. According to the method representing the decomposed systems, three different approximation methods are developed, along with a simple upper bounding method for throughputs. Extensive computational experiments are perform ....etc

ABSTRACT
Fiber Channel is an ANSI interface that acts as like a general transport vehicle to simultaneously deliver the command sets of several existing interface protocols. Fiber Channel Arbitrated Loop is one topology used to connect two or more devices within the guidelines set by the ANSI standards. It supports both large and small data transfers, and can be used in systems ranging from s ....etc
