According to the Storage Networking Industry Association (and who should know better?): A storage area network (SAN) is any high-performance network whose primary pur- pose is to enable storage devices to communicate with computer systems and with each other. We think that the most interesting things about this definition are what it doesn’t say: I It doesn’t say that a SAN’s only purpose is communication between computers and storage. Many organizations operate perfectly viable SANs that carry occa- sional administrative and other application traffic. I It doesn’t say that a SAN uses Fibre Channel or Ethernet or any other specific interconnect technology. A growing number of network technologies have archi- tectural and physical properties that make them suitable for use in SANs. 3 8646_Barker_01_d.qxd 9/20/01 10:21 AM Page 4 4 STORAGE AREA NETWORK ESSENTIALS I It doesn’t say what kind of storage devices are interconnected.

  • Effective Data Backup System Using Storage Area Network Solution
    Effective Data Backup System Using Storage Area Network Solution Ume, L.E. Department of Computer Science, Ebonyi State University, Abakaliki, Ebonyi State, Nigeria Correspondence e-mail: [email protected] Abstract One of the most crucial benefits of the computer system is its ability to manage data send to it for processing. An aspect of data management that all other aspects hinge upon is data storage and retrieval. Data loss has rendered many firms bankrupt. The primary cause of data loss is lack or non- existent of data backup. Storage Area Network Solution (SANS) is internet-based software which will collect clients data and host them in several locations to forestall data loss in case of disaster in one location. The researcher used adobe Dreamweaver (CSC3) embedded with PHP incorporated with MySQL database technology to develop the application. The objectives of the research were realized. Keywords: Backup, Storage area network, Data, Effective and Data loss 1.0 Introduction Storage Area Network (SAN) is a high- (NAS) systems. SAN evolved from the speed sub-network of shared storage concept of taking storage devices and devices. A storage device is a machine that therefore storage traffic, off the LAN and contains nothing but a disk or disks for creating a separate back-end network storing data. A SAN’s architecture works in designed specifically for data. This is a a way that makes all storage devices contrast to the use of a traditional LAN for available to all servers on a LAN or WAN. providing a connection for server-storage, a As more storage devices are added to a strategy that limits overall network SAN, they too will be accessible from any bandwidth.

Finally, my special thanks to my family for their encouragement and support during my stud ies. Siavash Hajirostam Halmstad, November 2013 i Abstract Due to growing the number of Information Technology (IT) users all around the world, consequently the amount of data that needs to be stored is increasing day by day. Single attached disks and old storage technologies cannot manage the storing these amounts of data. Storage Area Network (SAN) is a distributed storage technology to manage the data from several nodes in centralize place and secure. This thesis investigates how SAN works, the file system and protocols that are used in implementation of SAN. The thesis also investigate about other storages technologies such as Network Attached Storage (NAS) and Direct Attached Storage (DAS) to figure out the advantages and disadvantages of SAN , The main focus of the thesis project is on identifying the security vulnerabilities in SAN such as possible attacks in different SAN protocols.

The transmission medium can either be wired or wireless. The network is established and data is transmitted over it with the support of networking hard- ware and the software running on the hardware. Network hardware comprises equipment that generates the signal at the source, transmits the signal over the transmission medium, and receives and processes the signal at the destination. The software comprises protocols, standards, instructions, and algorithms that support transmission services over the net- work. The essentiality of networks has increased over time, along with advancement in network hardware, software, and support applications. There are huge variations in the size of a network in use; there can be small networks confined to an office or home, and at the same time there areCOPYRIGHTED networks spread across cities and MATERIAL countries. The spread of the network can be described in various terms, such as distance covered and the number of computers and other resources connected to the network. A local area network confined to a building may connect thousands of computers, such as in a software development center, a call center, or a stock exchange.

  • The Storage Area Network
    Chapter 1 The Storage Area Network In This Chapter ▶ Understanding storage area networks (SANs) ▶ Determining whether a SAN is right for you ▶ Looking at SAN layers and protocols ▶ Figuring out which operating systems benefit from SANs ▶ Discovering which applications can use or require SANs his chapter is dedicated to helping you get a handle on what a storage Tarea network (SAN) is, the basics of how one works, and whether one is right for your needs. You’ll discover all the parts that make up a SAN, the things that make one run, and who actually makes all the different parts that you can buy. Putting a SAN together is somewhat like putting together one of those high-end stereo systems; you have many components and many differ- ent manufacturers to choose from. This chapter helps you choose the ones that suit your needs and create something that you can be proud of. These days, becoming proficient with SANs can mean a major boost to your career. Perhaps you’re bored to death in your current position and would like a change of pace. SAN administration is one of the highest-paying jobs in Information Technology (IT) today. If you add storage area networking to your résumé, you may find your phone ringing off the hook as headhunters vie to offer you a six-figure income (hey, might as well dream big). COPYRIGHTED MATERIAL Defining a SAN First, the basics. In today’s terms, the technical description of a SAN (Storage Area Network) is a collection of computers and storage devices, connected over a high-speed optical network and dedicated to the task of storing and protecting data.

  • Flash Or SSD: Why and When to Use IBM Flashsystem
    Redpaper Megan Gilge Karen Orlando Flash or SSD: Why and When to Use IBM FlashSystem Overview This IBM® Redpaper™ publication explains how to select an IBM FlashSystem™ or solid-state drive (SSD) solution. It describes why and when to use FlashSystem products, and reviews total cost of ownership (TCO), economics, performance, scalability, power, and cooling. Read this guide for information about selecting the correct solution (SSD or flash technology). This paper also reviews examples of FlashSystem storage bundled with solutions such as hybrid arrays and IBM System Storage® SAN Volume Controller (SVC). Furthermore, it compares FlashSystem storage to other storage such as PCIe Express (PCIe) products and hard disk drives (HDDs). Business value of FlashSystem products FlashSystem storage systems deliver high performance, efficiency, and reliability for shared enterprise storage environments, which can help you address performance issues with your most important applications and infrastructure. FlashSystem products also provide capability for big data and cloud environments. These storage systems can either complement or replace traditional hard disk arrays in many business-critical applications: Online transaction processing (OLTP) Business intelligence (BI) Online analytical processing (OLAP) Virtual desktop infrastructures (VDI) High-performance computing (HPC) Content delivery solutions (such as cloud storage and video-on-demand) As standard shared primary data storage devices, FlashSystem storage delivers performance exponentially beyond that of most traditional arrays, even those arrays that incorporate SSDs or other flash technology. These storage systems can also be used as the top tier of storage © Copyright IBM Corp. 2013.
