Outcome 1 (1.1) Q1. Briefly explain following designing requirements that are required when
designing the Hardware and Software infrastructure: a) Storage requirements A lot of considerations
go into analyzing the storage requirements of a database server. In addition to the physical size of
the database, you need to consider the transaction growth rate and data–distribution requirements.
Some industries, particularly financial and healthcare institutions, are subject to requirements
regarding data retention, storage, and security that must be taken into account in determining storage
capacity. You'll now learn how to determine the current storage capacity of a database server and
identify factors that affect its growth. We'll also look at how to forecast future disk–storage
requirements, taking into account any relevant regulatory requirements that may apply to your
business or enterprise. b) Network requirements All database

A Short Note On Scsi Test Vehicle ( Stv )
Introduction
SCSI Test Vehicle (STV) is a project to develop an FCP Storage emulator using FICON Express
16G channel adapter present on System z machine. STV is a specialized Firmware (FW) load into a
channel adapter that provides the function of a FCP Target (Fibre channel SCSI Storage Control
Unit). STV emulates IBM shark disk storage.
This document is intended at describing the design and implementation of STV Emulation support
on Power Servers/Blades. The scope of this document is mainly limited to STV component in STV
Type FC channel firmware. This document contains information collected from other documents
and design discussions. STV Emulation support on Power Servers/Blades enables qualification/test
floor teams to use the STV Type channel firmware to test SCSI stream protocol capable devices not
just on system z but other servers such as zBX and zFX as well. Problem Statement
The Current STV based storage emulator requires a FICON express I/O Hardware and system z for
emulation. This is useful for testing in a System z environment but proves uneconomical in regular
zBX or zFX qualification. Moreover since STV uses the resources within the FICON express
module, which are limited. Emulation of Enhanced features such as multipath or increased LUNs is
not possible. This limits the test coverage of the test team. This project tries to work around some or
most of the limitations by moving STV emulation to a Power server.
Limitation of STV:
High cost of testing for

File Sharing And The Internet Piracy
In recent years, internet piracy or "file sharing" of copyrighted material has gained much popularity.
It is a topic that has incessantly sparked debate and has even received global attention. Although on
the surface the act of file sharing may seem harmless, it is far from it. Each year, film and record
production companies as well as software and video game development companies suffer from
billions of dollars in lost profits. This loss comes as a direct result of internet piracy. Many agree
that file sharing is unethical and consider it to be no different than downright theft. On the other
hand, there are those that support file sharing and claim that their actions are easily justified and
ethical. This essay will provide a brief overview and history of file sharing, will consider the
arguments of each side, and will offer my personal observations and stance on the issue.
File sharing, put simply, is the process of making available and distributing files via the internet.
Many freely developed applications have been made available that simplify this process, providing
the ability to easily search for, download, and upload any piece of digital content imaginable. These
applications are commonly referred to as P2P or peer–to–peer applications as they allow individuals
(peers) to directly connect with other peers to share files. By themselves, such applications are
useless; a central network must be available that allows each peer to see one another. These

Malware Problem Analysis Paper
Problem
Malware, as defined by the National Institute of Standards and Technology, "refers to a program that
is covertly inserted into another program with the intent to destroy data, run destructive or intrusive
programs, or otherwise compromise the confidentiality, integrity, or availability of the victim's data,
applications or operating system. (M. & K., 2013)" This is a threat to all companies with any type of
internet access and/or electronic information storage. That is currently a large number of both small
and big businesses.
Some important terms to take into account here is confidentiality, integrity and availability. These
terms are known as CIA and are the core principles of information security. Malware will affect all
three indefinitely if left unchecked. This will not only hurt a company's revenue but will potentially
also hurt their reputation if wide scale enough. Malware is, by Gulf South Tech Solutions,
considered to be the biggest threat to a business. With over 5,000 new malware attacks every day,
the average time to resolve being over 25 days, the average financial cost being $3 million, and over
60% of the websites that infect a computer being legitimate sites that were compromised makes
defense of paramount importance now more than ever. (Gulf South Technology Solutions, 2015)
Solution
The fix to the Malware problem is the implementation of the NIST SP 800–83 regulation. It covers
all aspects of malware handling and will assist in mitigating the

Review: Career Direction Precision Metalworker
Moore, Pam. "Career directions precision metalworker." Scholarly Journals(2003): 36–37. Web.
Nov. 2003.
I am using this source because it was found on a reliable website. The author seems to have a great
deal of knowledge in the environment and job of a toolmaker. She also talks about the work
environment.
"Precision metalworkers are among the most highly skilled production workers." (Moore) They
make tools, dies, and special guiding and holding devices for machines that mass produce products
that are used daily like cell phones, appliances, and heavy equipment. Tool makers create tools to
shape, cut, and form metal and other materials. They also make devices that hold metal while it is
being drilled or stamped. Gauges are also make by Tool ... Show more content on Helpwriting.net ...
With the ideal of running high speeds, most cutting tool makers say the cutting capability of most
inserts is not fully used yet. The push for cutter upgrades is in opposite directions. Tool makers with
consistent jobs want cutters created for specific materials and speed ranges, but those with more
general work want one tool to do more with less changing of tools and inserts. A lot can be done to
improve cutting tools, including insert geometry, different materials, and different holders. As the
range of spindle speeds and feeds gets wider, the need to upgrade tool holders has gotten greater to
reduce vibration and movement of the tool. One huge benefit of having better inserts and stiffer
turning machines is a process called hard turning. Here recently it has been replacing some grinding
practices as well as opening up new applications and opportunities. Instead of rough cutting and
then hardening, and finishing by grinding, hard turning is done on a lathe after the hardening
operations have already taken place. Machine cutting tool makers will soon be faced with a new
group of problems as composites, more particularly carbon–fiber–reinforced materials become more

the same no–advertising strategy. However, her environment friendly business positioning was
easily replicated by competitors like Estee Lauder and Revlon) f. High personal values (However,
she herself says that this might have been a problem '...........I have never been able to Body Shop

File Sharing And The Internet
File Sharing
"I 'd like to propose another toast to you, the listener. It doesn 't matter how you got this, you bought
it, you downloaded it, and your grandma gave it to you." (Jones). Chances are anybody who has
ever used the internet has downloaded copyrighted material. Many people view downloading
copyrighted material from the internet as stealing, but others see it as a distribution of human
knowledge and information. File sharing, more formally known today as torrents, should be legal.
File sharing is only illegal if the material that is being distributed is copyrighted. Even then if the
creator of the content chooses to distribute their material in this format it is also legal. Companies

Floppy disks had shrunk down to their final format which was three and a half inches. "In 1992
floppy disk piracy was so popular that a campaign called 'Don't Copy That Floppy' started" (Smith).
The campaign mainly featured little white kids rapping about floppy disks.
"The controversy which defined file sharing for this period surrounded one file format – the mp3"
(Smith). In the late 1990s, Napster, a web service that provided mp3 files to people who paid a small
subscription fee, was founded and was known for hosting a large amount of mp3 files that anybody
could download. That same year a service called Audiogalaxy was created as well. The two sites had
friendly competitions to see who could get more web traffic and downloads. Napster was shut down
due to copyright infringement in 2001. Audiogalaxy closed soon after due to pressure caused by the
RIAA (Recording Industry Association of America) and was sold to Vivendi Universal, a company
that would later turn the service into Rhapsody.
In the same year that Napster was shut down, Windows released its new software version which
would replace Windows 98. "Windows XP, released in 2001, included a feature called Simple File
Sharing which made it easy for Windows users to file shares among computers on a local network."
(Smith). In simpler terms, if one family used more than one computer in their household they could
get any file from one computer to another.

As was mentioned above, their core business is the supply–demand matching platform they create.
They tend to keep traditional activities and transactions outside of the company as much as they can.
Although they don't need to maintain or manage the buildings or any other physical property for
their business, their main challenge is to manage the information in their market platform. They also
need to find their suppliers rather than only managing only customers. 3. Double income sources,
two–sided networks. As they are acting as a matching medium, they have to satisfy the needs of a
group of people. It increases their costs, but also increase their revenue. Unlike the traditional travel
companies who only have one large income source from their customers, these companies have two
part of smaller income sources; one is from the "hosts" and the other is from the "travelers".
Moreover, their targets are wider than traditional traveling companies. Since they are charging a
small fee, they need to scale up their booking in order to make profit. Therefore, they have to find a
way to better identify and discriminate their target audience. Airbnb Idea from sofa surfing Airbnb is
one of the hottest startups in history and the new star in the hospitality industry. It provides an online
platform that enables individuals (hosts) to rent rooms, flats, even whole houses directly to
travellers. Brian Chesky founded this company in 2008, and has

Another feature that "Ubuntu" offers is the ease of authentication. Authentication plays an important
part as it helps computers on a network to recognise each another and allows for information to be
shared. "Ubuntu Server" comes with "Open Lightweight Directory Access Protocol (LDAP)". This
ensures that a shared directory service can be built if it is needed.
Supported versions of Ubuntu Server come with "Likewise–Open". This is used to integrate with the
system using Microsoft Active Directory. Machines on Active Directory can be identified, share
credentials and access resources with "Ubuntu" machines through the use of this software.

Roddick. On October 23, 1942 in Littlehampton, Sussex, England marks her birth to an immigrant
Italian family. After completing her degree at the Newton Park College of education, she worked as
a part–time teacher and for the United Nations in Geneva. After that, she travelled to different places
like Tahiti, New Hebrides, New Caledonia, Reunion, Madagascar, Mauritius, Australia, and
Johannesburg. Her fascination with the women she encountered in these places became an episodic

Roddick started with small bottles since that was what she was complaining on. They, lesser
materials should be used to produce smaller, thinner and lighter packages. This is one of the ways by
which a company can minimize packaging costs, and at the same time, maintaining products to be in
line with "green". Supporting the environment is ensconced in the Body Shop from the very
beginning. Years later, as the Body Shop grew larger and larger, Roddick combined principles with
profit.
Personality has much to say in defining Roddick's success. In Roddick's eyes, Body Shop succeeded
because of two reasons. Economic survival of her family, especially during its beginnings, was a
primary driving factor; and, the passion to establish a shop of her own and to engage in trading was
the other. She therefore succeeded not because of a capitalist goal, which is profit. What she did was
she thought of ways to survive in the market. She did not dream of a big shop. The shop eventually

The file system that manages the storage across network of machines is called distributed file
systems. Hadoop mainly comes with the distributed file system called HDFS (Hadoop distributed
file system).
HDFS Design: The HDFS file system is designed for storing files which are very large means files
that are hundreds of megabytes, gigabytes and terabytes in size, with streaming data access patterns,
running on commodity hardware clusters. HDFS has a idea of write once read many times pattern. A
dataset is typically generated or copied from the source and various analyses are performed on that
dataset. And hadoop does not need expensive hardware. It is designed to run on commodity
hardware.

The Body Shop International Plc
After the boom of the third industry and the foundation of WTO, companies are now facing more
severe competitions than ever before, not only domestically but also internationally. Therefore,
figuring out how can we survive the competition and stand out from the others have been put ahead
of the schedule of plenty of enterprises. While many others are scrambling for marketing their
invariable products–paying more attention to propaganda, packaging price strategies etc. some other
have found it more crucial to be innovative. But that is not enough, to achieve greater success, one
must combine proper management and adequate entrepreneurial part, and this technique has later
evolved into the term "entrepreneurial management". In this essay, I will mainly talk about how
companies using the "entrepreneurial management" make themselves distinguished from the others
and what value they create through this strategy by studying the case: The Body Shop International
Plc. First of all, I will give a brief introduction to the background of The Body Shop International
Plc. Then the essay will go further into the definition of the Entrepreneurial Management Model,
which is introduced to people by Dr. David Rae (2007), and how The Body Shop explains the
concept of the model by illustrating the management strategies the company uses and the
entrepreneurial skills it adopts respectively.

Usb Drives And Usb Drive Data Transfer
CHAPTER 1 INTRODUCTION 1.1. INTRODUCTION Portability and mobility of storage devices
like flash drives and USB devices are becoming so popular to carry and transport data on the go.
Unlike CD/DVD, hard drive, floppy disk or tape drive, a flash memory has no moving parts, so it
guarantees fast read/write speeds and more durable compared to other forms of storage media.
Using a flash drive/memory card to transfer a file typically uses a computer (e.g. laptop, pc, netbook
or tablet) to initialize mass storage communication which is not portable. Smartphone can exchange
the data through Bluetooth but can't act as host to USB drive to USB drive communication for data
transfer. The proposed system bridges the gap of USB drive to USB drive data transfer when a
computer is not present. Because of low prices of Smartphone almost everybody use smartphone so
even Smartphone can't act as host but it can acts as mediator and can be used as user interface to
give operational command for data transfer. Moreover, booting a computer just to transfer a file/s is
ridiculous. In an earlier research, an embedded system is used wherein a slave to slave flash drive
transfer makes it possible to transfer file/s using a programmable microcontroller with USB multi–
role embedded host/peripheral controller and navigation control. This makes it possible to transfer
data from a flash drive to another flash drive with 100% data integrity using MD5 checksum
algorithm. That research also

account should be merged. This is because it becomes rather complicated to handle many Outlook
PST files at a time and users unable to extract information from them. The main purpose of all the
users is to combine multiple PST files by keeping the data items in the mailbox safe.
Most Outlook users need to create several archive PST files in the previous edition of Microsoft
Outlook to evade the risk of corrupted data and slow performance. But, recently in the modern
Outlook editions such as Outlook 2016, 2013, 2010 and 2007, there is no file size related issues with
Outlook PST files. Various files are stored on different locations (depends on user requirements), but
a time comes when user wants all these PST files to be stored on one location in form of a single
entity. It makes sure that when PST files are merged into a new file, the original PST files should
remain intact. Thus, in the following section we will discuss what combine process in Outlook,
manual method to combine multiple PST files into a single Outlook data file, advantages after
combining Outlook PST files, limitations and solution to combine multiple Outlook files.
Reasons and Scenarios to combine multiple

Taking a Look at Virtualization
VIRTUALIZATION Virtualization is a concept in which access to a single underlying piece of
hardware, like a server ,is coordinated so that multiple guest operating systems can share that single
piece of hardware ,with no guest operating system being aware that it is actually sharing anything at
all. Working mechanism–Virtualization software tackles the issue by empowering many operating
systems and applications to run on one physical server or "host." Each independent "virtual
machine" is secluded from the others, and uses as a great part the host's computing resources.
Contrast b/w (OS) & the Guest OS–The host is the virtual machine host server; the underlying
hardware that gives computing resources, for example processing power, memory, disk and network
I/O etc. The guest is a totally separate and independent instance of an operating system and
application software. Guests are the virtual workloads that dwell on a host virtual machine and
contribute in that server's computing resources. Packages–Hardware virtualization alludes to the
production of a virtual machine that demonstrations like a true computer with an operating system.
Software executed on these virtual machines is divided from the underlying hardware resources.
Desktop virtualization is the idea of differentiating the logical desktop from the physical machine
.One type of desktop virtualization, virtual desktop infrastructure (VDI), could be thought as a more
advanced form of hardware virtualization.

Essay on The Global Ethical Perspective of Peer-to-peer...
The Global Ethical Perspective of Peer–to–peer File–sharing
Introduction
This paper is an analytical essay on global ethical issues on peer–to–peer (P2P) file–sharing. A
history and background of peer–to–peer file–sharing will be given, as well as how it became an
issue. This paper will explore what aspects of file–sharing are ethical and at what point it becomes
unethical. An explanation of the laws will be described and whether the laws different from region–
to–region around the world. The paper will include personal experiences with file sharing, as well as
an in–depth analysis on the topic with high–quality industry and academic references to defend a
particular moral/ethical position.
Background
The Internet is a shared ... Show more content on Helpwriting.net ...
Not everyone thought this was such a great idea, however. Some objections cite legal or moral
concerns. Other problems were technical. Many network providers, having set up their systems with
the idea that users would spend most of their time downloading data from central servers, have
economic objections to peer–to–peer models. A long–established fixture of computer networking
that includes important peer–to–peer components is Usenet, which has been around since 1979.
Usenet news implements a decentralized model of control that in some ways is the grandfather of
today's new peer–to–peer applications such as Gnutella* and Freenet*. Fundamentally, Usenet is a
system that, using no central control, copies files between computers. So the bottom–line is that
file–sharing has been around for a long time now and that its decentralized nature makes is hard to
control besides holding each individual sharing files accountable. Peer–to–peer systems go hand–in–
hand with decentralized systems. In a fully decentralized system, not only is every host an equal
participant, but there are no hosts with special facilitating or administrative roles. In practice,
building fully decentralized systems can be difficult, and many peer–to–peer applications take
hybrid approaches to solving problems. [1]
Laws and Issues Associated with File–sharing
File–sharing in itself is not an issue until

The Is Regulation And Its Impact On The Landscape Of Long...
There is no doubt that the recent introduction and rapid growth of the new "shared economy"
companies have materially changed the landscape of long–standing industries. With this change has
entered benefactors, victims and much controversy and debate as to the overall merit and value these
companies add to communities and cities both domestically and worldwide. Also, because of the
continuing growth of these shared economies, the existing and impacted populations and
government bodies are too in flux, responding and evolving. Essentially then, the battleground is
regulation; specifically the how, what, when, where and why of regulation is what is being debated,
challenged, litigated, legislated, protested and formulated worldwide, in municipalities of all sizes
and in the various industries that the shared economy companies have been able to enter, and in
some cases dominate in a short time, literally having taken a substantial market share. Although San
Francisco is a flashpoint of current regulatory tug of war for various industries, especially in
transportation and housing, the Airbnb and its impact has been on the minds of legislators
worldwide for at least a couple of years. In December 2014, Sawatzky listed 45 government bodies
that were in the process of addressing the impact of Airbnb in their communities. Sawatzky states
that "in most cases the intention seems to be to create more precise definitions of "short–term
rental," to implement oversight

Analysis Of The Biography ' Stephenie Meyer '
Author's Biographical Information
Stephenie Meyer was born as Stephenie Morgan on December 24, 1973 in Hartford, Connecticut to
her parents Stephen and Candy Morgan. Her family relocated hen she was only four to Phoenix,
Arizona, where she was raised with her three brothers; Seth, Jacob, and Paul, and her two sisters;
Emily and Heidi. Stephanie had to obtain the duties of caring for her younger siblings and, during
that time, she had developed a great love for reading books from classic authors such as Jane
Austen, Charlotte Bronte, and Margaret Mitchell. In 1988, she attended Chaparral High School in
Scottsdale, Arizona and was a successful student despite the feeling of alienation among the highly
populated crowd. She graduated in ... Show more content on Helpwriting.net ...
She is the soul that has been placed inside the body of an unwilling human host that once belonged
to a girl named Melanie Stryder. Her true form owns the same appearance as all "souls"; ghostly,
silver, and reflective with many small, feather–like attachments. However, while inhabiting the body
of her host, Melanie Stryder, she obtains her physical attributes, which include tan skin and long,
dark, and glossy hair. Her name implies her traits; she was named Wanderer because, in her previous
eight lives, she had traveled to many planets and knows little to nothing about human culture and
behavior, making her stick out of the crowd of humans. It is safe to assume that she is a pacifist, for
she states in the book multiple times that her kind doesn't believe in violence. At the end of the
book, Wanderer is placed into another host and gains long, golden hair, freckles, gray eyes, a
dimple, and a decrease in height. She becomes delicate and petite, for the soul that was in the body
last was that way.
Melanie Stryder is a major character in the book, for she is the previous owner of the body that
Wanderer was placed into. She is quite defiant in the beginning, refusing to cooperate and allow
Wanderer to take over her body completely. This creates conflict for both girls because they are
nothing alike. Melanie is very determined and is known to have a negative mind,

Storage Requirements And Data Distribution Requirements Essay
Storage requirements: – storage requirements is first and most important in designing. A great deal
of thought go into examining the storage requirements. The physical size of the database, you have
to consider the exchange development rate and data distribution requirements. There are some topic
which are assessing current storage capacity:–
Disk–space capacity
Disk throughput capacity
Locations and roles of database servers
Network requirements: – all database administrators and infrastructure ought to have a stray pieces
comprehension of the topology of the system supporting the database servers on the grounds that
this effects infrastructural choices.There is some analysing current database network traffic
services:–
Traffic between servers
Traffic between clients and servers
Potential bottlenecks
CPU requirements: – central processing unit is the main part of the computer and also main part of
our database server infrastructure. When you choose any CPU for your database u must check the
performance of the CPU and also you need check which type of processor is this processor
comparable for your database requirements.
When you're analysing the current CPU performance of a database server, consider the following
factors:
Type of CPUs
Affinity mask settings
Current CPU usage
Memory requirements:– memory is likewise imperative piece of PC means memory is mental ability
of PC. At the point when surveying the memory prerequisites of a database server,

A Short Note On Ms. Carlson 's Accident
Mr. Werman is not likely to be found liable for Ms. Carlson's accident. There are four elements for
social host liability, (1) the host knew the guest was intoxicated, (2) the host furnished alcohol to the
guest even after the guest was intoxicated, (3) the guest negligently drove intoxicated, (4) the host
knew or should have known the guest would have driven. McGuiggan v. New York Telephone &
Telephone Co., 398 Mass. 152, 496 N.E.2d 141 (Mass. 1986). Mr. Werman knew the guest was
intoxicated. However, he did not provide Ms. Carlson with alcohol. Ms. Carlson negligently dove,

In this case, Mr. Werman knew Ms. Carlson was intoxicated by the behavior she displayed while he
was talking with her at the party. Ms. Carlson held a beer and her breath smelled of beer when she
was talking to Mr. Werman. Similarly, to Pollard, Ms. Carlson displayed obnoxious behavior while
speaking to Mr. Werman. She hugged him several times and showed a significant amount of
enthusiasm for Mr. Werman's new job. Mr. Werman thought the behavior was strange for an
acquaintance. In McGuiggan the guest displayed sober behavior, Mr. Werman believed that Ms.
Carlson's behavior was not normal for a guest in her situation. Therefore, based on Ms. Carlson's
behavior, Mr. Werman knew that she was intoxicated.
B. Mr. Werman did not provide alcohol to Ms. Carlson.

C. Ms. Carlson's drunk driving was not foreseeable.
Mr. Werman did not foresee Ms. Carlson driving intoxicated. The host reasonably foresees a guest
will drive intoxicated if the host express concern about the guest 's ability to drive. The court stated
in Makynen that because the host expressed concern his guest's ability to drive, the host reasonably
foresaw his guest would drive while intoxicated. Makynen v. Mustakangas, 39 Mass. App. Ct. 309,

What are the safe working practices and procedures to be followed when preparing and using the
milling machines?
When operating a Milling machine there are a lot of health and safety laws that have to be followed
when preparing to use and using a milling machine, the laws and safety precautions that must be
taken are as follows:
Gloves or hand wear must never be worn whilst working on a milling machine; any types of hand
wear like watches, bracelets and bangles could get snagged on the cutter and wind the operator into
the machine ... Show more content on Helpwriting.net ...
Coolant– coolant spills are a problem that can be prevented but on some mills there is a point where
coolant leaks from the bed and drip down hitting the floor around the machine this caused by a
blockage in the slots within the bed causing it to over flow with coolant creating a spillage.
Entanglement– the operator of the machine can risk entanglement from lose clothing becoming
entangled in the cutter this could wind the operator into the machine cutter causing serious injury.
Sharp edges – sharp edges or burrs are a hazard when handling the components it is possible to
injure yourself on these razor sharp burrs.
Training– If an operator has insufficient training then they are a danger to themselves and others
around the machine
3.)
What personal protective equipment needs to be worn for the milling activities?
There is several pieces of PPE equipment that must be work whilst milling, equipment is as follows:
Before work cream: This will stop irritations and protect the skin from infections from substances
being used whilst turning.
Safety glasses– protective eye wear must be worn since swarf and coolant is travelling and can be

flying in any direction.
Overalls– This stops flying swarf and coolant reaching your skin and causing damage or harm.
Safety boots– safety boots are of the main pieces of PPE, this will protect the feet from swarf and
coolant and there is a steel toe cap for protection against objects

The Common Internet File System
8. Data Storage Techniques
8.1 CIFS
The Common Internet File system (CIFS) is a native file sharing protocol used by computer users
across corporate intranets and Internet. It defines series of commands to pass the information
between the networked computers. CIFS implements the client/server programming model. A client
program sends a request to server program for access to a file or to pass a message to a program that
runs in the server computer, the server then takes the requested action and gives a response.
CIFS Functions are:
● Get access to files that are local to the server and read and write to them
● Share files with other clients using special locks
● Restore connections automatically in case of network failure.
● Unicode file names
Similar to SMB protocol, CIFS implements the Internet 's TCP/IP protocol. CIFS can be considered
as supplement of existing Internet application protocols such as the File Transfer Protocol (FTP) and
the Hypertext Transfer Protocol (HTTP).
Common Internet File System runs as an application–layer network protocol used for providing
shared access to files, printers, serial ports, and miscellaneous communications between nodes on a
network. It also facilitates an authenticated inter–process communication mechanism.
8.2 Network File System (NFS)
Sun Microsystems in 1984 developed a distributed file system protocol called Network File System
(NFS) allowing a user on a client computer to access files over a network much like local

Advantages Of SAMBA
1.0 OBJECTIVE
In this report, we make a research about network internet services application. After we discus about
this network internet services application we will choose to research about SAMBA because it use is
extensive in businesses, governments, and organizations. After going through this report the reader
will able to:
I. Define what is SAMBA
II. Able to know how SAMBA working with Window application
III. Determine Advantages of SAMBA.
IV. Able to know configuration of SAMBA
2.0 INTRODUCTION
In this project we decide to choose SAMBA for make some research to determine their function,
how to configure step by step, how it work and SAMBA advantages. SAMBA is a program that
allows end users to access and use printers, files, and other commonly shared resources on the
Internet. SAMBA allow two or more operating system to connect with to one another .SAMBA is
based on the common client/server protocol of Server Message Block (SMB) and Common File
System (Internet CIFS). ... Show more content on Helpwriting.net ...
SMB stands for "Server Message Block". It is file sharing protocol and designed to allow computers
to read and write files to a remote host over a local area network (LAN). The directories on the
remote hosts made available via SMB are called share.
NFS stands for Network File System and serves essentially the same purpose as SMB. NFS in
incompatible with Window clients and it is useless for Mac file sharing clients due to missing
features and performance problems with Mac apps.
SMB/CIFS Benefits:
– Share file systems
– Share printers installed on both the server and clients
– Authenticate clients logging onto a Windows domain
– Samba is freely available, unlike other SMB/CIFS implementations, and allows for
interoperability between Linux/Unix servers and Windows–based clients.
NFS Benefits:

– Can achieve higher transfer speeds
– Typically uses a lot less server CPU

Architecture Of Glusterfs As A Scalable File System
GlusterFS is scalable file system which is implemented in C language. Since it is an open source its
features can be extended [8]. Architecture of GlusterFS is a powerful network written in user space
which uses FUSE to connect itself with virtual file system layer [9].
Features in GlusterFS can be easily added or removed [8]. GlusterFS has following components:
GlusterFs server storage pool – it is created of storage nodes to make a single global namespace.
Members can be dynamically added and removed from the pool.
GlusterFs storage client – client can connect with any Linux file system with any of NFS, CFS,
HTTP and FTP protocols. Fuse – fully functional Fs can be designed using Fuse and it will include
features like: simple ... Show more content on Helpwriting.net ...
That somehow defeats the purpose of a high–availability storage cluster, must synchronize the
system time of all bricks, clearly the lack of accessible disk space wasn't GlusterFS's fault, and is
probably not a common scenario either, but it should spit out at least an error message.
2.4. HDFS File System
Hadoop distributed file system is written in Java for Hadoop framework, it is scalable and portable
FS. HDFS provide shell commands and Java application programming interface (API). [12] Data in
a Hadoop cluster is broken down into smaller pieces (called blocks) and distributed throughout the
cluster. In this way, the map and reduce functions can be executed on smaller subsets of larger data
sets, and this provides the scalability that is needed for big data processing. [12] A Hadoop cluster
has nominally a single namenode plus a cluster of datanodes, although redundancy options are
available for the namenode due to its criticality. Each datanode serves up blocks of data over the
network using a block protocol specific to HDFS. The file system uses TCP/IP sockets for
communication. Clients use remote procedure calls (RPC) to communicate with each other.
Fig 5. HDFS Architecture [19]
HDFS stores large files across multiple machines. It achieves reliability by replicating the data
across multiple hosts, and hence theoretically does not require redundant array of independent disks
(RAID) storage on

Threats Facing The Server, Workstations, And Website
Recently, a series of security incidents on the company 's website, workstations, and network have
been brought to the attention of the company. These incidents include the slow and sluggish
behavior of workstations, advertisement pop ups on workstations not accessing the internet, deletion
and defacement of the website, and reports by customers of the website becoming unavailable.
While the incidents are being remediated, this has necessitated compiling information on potential
threats the company 's network assets face. In that endeavor, it is recommended to review this list of
the current top 5 threats facing the server, workstations, and website. Understanding how these
threats potentially impact the company is vital in developing controls and countermeasures to the
threats listed and could prevent additional future threats that take advantage of the same vectors.
Threats to the Server 1. Buffer Overflow Attack A buffer overflow attack is a threat to the server
with serious potential consequences. In a buffer overflow attack overly long input streams are sent
to the server. This will cause the server to overflow parts of the servers memory, the goal of the
attack will be to execute arbitrary code embedded in the input streams as if it was the servers code.
Even if the attack fails, it can cause a process, application, or the server to crash. Upon a successful
attack data can be added, destroyed, or an attacker can gain control of the server. Without data

Analyzing And Improving Reliability Of Storage Systems
Much work has been done on analyzing and improving the reliability of storage systems. We
classify the existing work into two categories based on the target systems studied, and explain why
state–of–the–art approaches are limited in helping diagnose the root causes of failures in flash–
based storage systems in this section.
Flash chips and devices. As mentioned in Table 2, many studies have been conducted on the
reliability of raw flash memory chips [1–8, 23, 24]. Generally, these chip–level studies provide
important insights for designing more reliable SSD controllers. However, since modern SSDs
employ various fault tolerance or prevention mechanisms at the device level (e.g., ECC [25,26] and
wear leveling [27]), the chip–level analysis can hardly be used to explain the storage system failures
observed in the real world.
Our previous study [22] is one of the very first work to analyze the device–level failure modes of
SSDs. However, although the framework is effective in testing and exposing errors, it cannot help
diagnosing the root causes of the failures observed. Moreover, since it is built on top the block IO
layer, it is fundamentally limited in separating real device defects from kernel bugs (as shown in
Table 1).
Host–side storage software. Much work has been done on analyzing the reliability of general storage
software [22, 28–32]. For example, our previous framework [31] simulates failures at the driver
layer and analyzes the recovery capability of databases.

Airbnb, who in less than a decade has built a major competitor to the centuries old hotel industry.
