Essay On Distributed File System

Once one of the computers is properly configured as a file server, users can access the storage by mapping the drives on the respective computers. The file server will be mapped as a drive and users can store, edit and access files directly from the shared storage disk. The disk will be connected to each computer. For example, when a user needs to access any file from the file server, he/she can access the drive that will now be mapped on the every computer (Science - Opposing Views, 2014).

The consequences of leaving all their information in one location can be catastrophic to the company’s operation and integrity as valued by their clients. Remotely storing vital information should be the first precaution taken when installing an archive full of fragile data. NAS (network attached storage), typically used in the form of cloud or RAID devices provides a safe approach to storing company information. “Common uses are central file storage, media streaming, print serving and backup for all the local drives on your network. You can even access most NAS drives from the Internet if desired.” (How to Buy Network-Attached Storage Drives, Becky Waring). If the NAS devices aren’t sufficient, file servers can support up to 25 users simultaneously and meet the high demands of the usage that typically come with a large network.

The customer required that each workstation have at least 256 GB to 500 GB of local storage. They also wanted a file server on the network to protect data in case a workstation went down. This server will be networked into allow file sharing between devices and have available 40 GB to start. These network upgrades, the greater use of applications, and file sharing will require more protection; a new firewall programmed to filter packets and analyze external requests and direct requests and traffic to the right application.

Samba specifically supports Linux access to print services for Windows alongside CUPS and file services as well as authentication through a daemon called Winbind. Winbind, provides communication for Pluggable Authentication Modules (PAM) and Name Server Switch (NSS) on the Linux side with Active Directory on a Domain Controller. It uses Kerberos and Lightweight Directory Access Protocol (LDAP) to authenticate and retrieve user and group information. (Kirkpatrick, 2008) Printing capabilities from the Linux systems will be essential and will most likely be very similar to the requirements with the user tasks in the current XP configuration. Since the print services are managed by Windows resources, meeting the printing needs of the Linux users will be accomplished through SMB using Samba. The printers currently active on the network have been verified to work with Linux systems, so once properly configured, Linux users will have no problem with their printing needs. The protocol for Samba is already integrated into the Windows Server environment so configuring the settings on both the Linux and Windows sides is not a complicated process, although it is an additional requirement that would not be required for a Windows client workstation. (Shinder, 2012) The information required to configure Linux systems to print in the existing environment consist of the print server, printer share and appropriate Windows login password. A script using smbclient shell will support the setup for printer configuration. File sharing in a structured environment is a useful feature that is common in a Windows environment and provides ease of access based on permissions established for designated file shares. Fortunately, this capability is not restricted with the integration of Linux. Samba is a versatile package that can serve as the solution for many areas to include file

I setup windows 2008 server create Microsoft Active Directory(AD), AD can centralize all user accounts for management and setup use right to access File Server permissions can enhance the level of flexibility in management.

The file and printing services will be put on the same server because they will more than likely be used together. “A file server allows you to centrally locate files to be accessed by multiple people. Because the files are centrally located, it is easier for multiple users to access and find files (assuming they are organized well) and it is easier to back up these files. When using Microsoft Windows to provide file sharing, you will usually be using Server Message Block (SMB) to access Microsoft Shares or shared folders” (MOAC,2011). As for the printing side of the server, “multiple users can access a centrally located printer using print services,

One way a filing system is created is by using the computers server on the network in which employees have access to the employees will create new folders for client files, this means that every time a new company partners up with the business i.e. for a potential deal, a new folder will be made in the company’s name under client files on the networks drive for the company’s relevant documents that will be stored here. By clicking into this it gives an A-Z list of folders of all the clients the business has worked with, we can the click into the folder and store or retrieve relevant information about the company such information might include documents based on whether the company is credit checked etc, this makes it easier to locate information in the future as it has been stored specifically in a file in which we will know where to retrieve this from when the relevant documents are needed in the

37. What policies work with folder redirection to provide the ability to cache files locally? Offline file storage

The world is changing daily and many companies are looking to develop ways to save on production and hardware. The idea of having a system that allows a company to store files away from the main server will help a company to store more and

To separate the requirements out into separate servers I would recommend 3 servers. One server for a master file directory where employees can share and access files, via a shared drive(s) (example X:/ACME_shared_files), this could be set up with the computer management tool and group policies could be setup in the server management tool for user login.

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

Abstract - Hadoop Distributed File System, a Java based file system provides reliable and scalable storage for data. It is the key component to understand how a Hadoop cluster can be scaled over hundreds or thousands of nodes. The large amounts of data in Hadoop cluster is broken down to smaller blocks and distributed across small inexpensive servers using HDFS. Now, MapReduce functions are executed on these smaller blocks of data thus providing the scalability needed for big data processing. In this paper I will discuss in detail on Hadoop, the architecture of HDFS, how it functions and the advantages.

The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result, Torvalds studied Minix and proceeded to set out to write a new version. After six months of working to produce the new operating system, Torvalds made very little progress toward the utility of the system.
