Assignment 1 Disk Redundancy Research 1. RAID stands for Redundant Array of Inexpensive Disks and at the simplest level it combines many disks into one logical drive. 2. We use RAID to avoid the lagging of computer performance. The basic idea of RAID combined multiple small‚ inexpensive disk drives into an array of disk drive which yields performance exceeding that of a large expensive drive. Moreover‚ this array of disk drive appears to the computer as a single logical storage unit. 3. Define

Independent) Disks. 2. When you need to take the time to restore those backups and those backups could be hours or days old‚ resulting in data loss. RAID allows you to survive a drive loss without data loss and in many cases without any downtime. 3. RAID 0 - Never‚ unless the data has no value to you. RAID 1 - If you are looking to inexpensively gain additional data redundancy and/or read speeds. A good base RAID level for those looking to achieve high uptime. RAID 5/6 - Web servers and high

Speed of a Computer Patrick Reagan Computers and Information Processing/CIS319 David Avery Jr. December 14‚ 2008 Speed of a Computer Computers have evolved dramatically over the last 70 years. The size may be one of the main changes. The first computers were the size of a classroom. Today a computer can fit in an adult hand. Another change is the speed in which the computer operates or processes information. The computer user in today’s market wants information

HISTORY OF INTEL PROCESSORS Today‚ computers are a part of our lifestyle‚ but the first computer that was used was developed at the University of Pennsylvania in the year 1946! It had an ENIAC (Electronic Numerical Integrator And Computer) processor. The reprogramming feature that is so extensively used today‚ was introduced by Alan Turing and John von Neumann with their teams. The von Neumann architecture is the basis of modern computers. From the development of the first microprocessor - Intel’s

economically viable alternative to other storage networking solutions. Justify this statement. Ans- DAS provides an economically viable alternative to other storage networking solutions as- • DAS configuration is simple and can be deployed easily and rapidly. • Setup is managed using host-based tools‚ such as the host OS‚ which makes storage management tasks easy for small and medium enterprises. • DAS is the simplest solution when compared to other storage networking models • Requires fewer

independent disks. Below are some RAID configurations with a brief description. RAID 0 Is the fastest of all the RAID levels‚ it uses a technique called data striping (see below) and requires at least two hard disks. RAID 1 This level uses a pair of hard disks at a time to provide fault tolerance (there is no performance benefit) and requires at least 2 hard disks. Using a technique called disk-mirroring (see below) the same data is written to both disks at a time‚ so if one hard disk crashes

Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server‚ but is specialized for this task either by its hardware‚ software‚ or configuration of those elements. NAS is often manufactured as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role
