A network-attached storage (NAS) device is a server that is dedicated to nothing more than file sharing. NAS does not provide any of the activities that a server in a server-centric system typically provides, such as email, authentication or file management. NAS allows more hard disk storage space to be added to a network that already utilizes servers without shutting them down for maintenance and upgrades. With a NAS device, storage is not an integral part of the server. Instead, in this storage-centric design, the server still handles all of the processing of data but a NAS device delivers the data to the user. A NAS device does not need to be located within the server but can exist anywhere in a LAN and can be made up of multiple networked NAS devices. What is the speed of the network adapter available on a NAS device? The speed is usually 1GB Ethernet connection but it can be changed to multiple Gb, 10Gb, fiber optic by adding a PCIe network card(s). It depends on the NAS device. Most newer ones will have Gigabit ethernet, very cheap or old ones may only be 100Mbit and high end ones may have 2 separate gigabit ethernet connections. What is the capacity range? Depending on the type and volume of content you plan to store, there's a choice of capacities...

...NT1110 July 31, 2013 Unit 6 Research Paper 1: Network Attached Storage A network-attached storage (NAS) device is a self-contained computer that is connected to a network. A NAS contains its own operating system that handles the function of data storage, file system, and the access to the files but doesn’t include a monitor, keyboard or other devices. NAS is dedicated for file sharing and allows more hard disk storage space and doesn’t need upgrades. The available speed of a NAS device varies but the usual speeds are 1 GB Ethernet connection however it can be changed to a multiple of GB and fiber optic by adding a PCIe network card(s). The capacity range also varies because there is no real limit to the NAS for example a board with six SATA ports can be replicated to allow thirty drives to be attached and up to 72TB of storage. There is fault tolerance (RAID) built into a NAS device if set up correctly RAID 50 is fairly stable, RAID 10 has been advertised as one of the best set ups because more drives can fail at one time without having data loss. A NAS device over all has its advantages it is great for file sharing and keeping all your files safe. So in a house where children and parents all have their own computer with pictures and videos it benefits them to have a NAS device where they can just store all those files and not worry about if one computer goes down all the files go along with the computer. http://technicallyeasy.net/2008/06/what-is-nas-device/...

Fall 2014 ASHIF ANWAR Illinois Institute of Technology-Chicago 11/30/2014 Contents: 1. Introduction. 2. History. 3. Product demonstration. 4. NAS future perspective. 5. Introduction Network Attached Storage is basically defined as a file level computer data storage server connected to a computer network. It is specialized for file server operation by its hardware, software or configuration of elements to provide data access to wide range of clients (Wikipedia, 2014). In simple words we can say “a network attached storage is a external hard drive which is a computer storage system that access and remains on a computer network via Ethernet and wireless connections. The drive is then accessible to all computers in a network, instead of one just hard wired computer”(Networking, 2014). Figure-1: NAS Storage on a network infrastructure. (slideshare, 2013). NAS is one of the popular approaches which allow homes and business to store and retrieve large amounts of data in an efficient and affordable manner. One can wirelessly backup their computer files such as music, videos and other important documents...

...Unit 6 Research Paper 1 Network Attached Storage ITT Tech Network attached storage (NAS) is basically a server that acts as hard drive that’s attached to a network. This connection to a network allows anyone who is also connected to the network the ability to access the hard drive. The NAS come in many sizes and different capabilities. The network connection that the NAS uses can be almost any that are available. The standard Ethernet connection is the most common connection by there are also systems that use a wireless connection or even a fiber optic connection for extremely fast transfer speeds. The storage of NAS systems can vary greatly. There are consumer models with a fixed amount of storage, and then the professional versions that have the capacity of many terabytes that can be upgraded when new drives become available. With the numerous amount of drives the chance of corrupted data and errors is always a possibility. With this possibility manufacturers have included the ability to arrange the drive into a RAID. The different RAID configurations allow users the protection from errors and data loss at the expense of storage space. NAS, unlike normal servers, do not require a keyboard, mouse, or monitor. They are usually managed from a remote terminal accessed via the NAS network connection. Some NAS systems use a web browser interface that uses the user’s web browser to interact with the NAS. Other systems use software that the manufacturer develops...

...2014 NT1114 Unit 6 Research Paper Network Attached Storage A Network Attached Storage device is like having an at-home cloud. It allows all the computers in a household to access the same massive storage device. Since NAS devices start at 2 TB of data, they can hold everything your family is going to need. If a single computer gets damaged and you are using a NAS device, you don’t have to worry about all of your data being lost. The computer is broken, but all of your home videos and pictures are safe and sound on your NAS device. There really are no limits to Network Attached Storage. With 1 GB Ethernet you can transmit just about everything you want as fast as you’re going to need it. You could also use a 10GB fiber optic cable too if you really wanted to. I guess the only real limit would be on a wireless network where you would be limited to the speed of your wi-fi connection. The capacity range of a NAS device is really only limited to the size of hard drives. A board with six SATA ports can be replicated to allow for 30 drives to be attached, if 3 TB drives are used in RAID 50 that would be 72 TB of storage, or approximately 72,000 full length movies. So you are going to be able to put as much memory on the NAS device as you’re going to need. It will only be a matter of cost that will limit you. And since RAID is very stable, there’s nothing really to be afraid of using this kind of storage. As for whether or not a family should use NAS, I believe it’s...

This capacity range also varies; you could build a 2 TB machine or a 40 TB machine. With port replication and add on hard dive controller cards there is barely a boundary on size. Is there any fault tolerance (such as RAID) built into a NAS device? Raid 50 is pretty stable if set up properly, raid 10 has been said to be one of the best because more drives can fail at once without data loss. Are management features available?

...Matt Bristow NT-1110 Unit 6 Research Paper NAS Devices NAS is an acronym for Network-Attached Storage. It is basically a file-level computer built for data storage connected to a computer network providing data access to any computer connected to that network. The speed for any particular NAS device varies from 1 gigabit all the way up to 10 gigabits depending on what upgrades a pc has such as an upgraded network cards. The capacity range for NAS devices also depend solely on the budget set forth. It can be a low range system with 500 gigabytes, all the way up to a wallet-busting 16 terabytes. The fault tolerances when set at RAID 10 are the most stable since more devices can fail while protecting against any potential data loss. The advantages of an NAS device are that since it is a dedicated file storage device, accessing said data is a lot faster than typical in-pc hard drives. Another advantage would be the amount of storage you're capable of having. It far outpaces pc's in storage capabilities because all it is built for is storage. For a family with a lot of pictures or videos, the advantages are that any computer connected to the NAS device can access them. It's a library for any media/documents/or anything else you can think of that can be accessed at any time by any pc connected to it. They might be pricey for a casual pc user but when dealing with multiple pc's connected to a single network, an NAS device would be the perfect option when space becomes an...

...Cameron White Unit 6 Research Paper 1 What is a NAS device? A NAS (Network-Attached Storage) is a server that is dedicated to nothing more than file sharing. It’s usually a network providing data access to a heterogeneous group of clients. NAS usually has a speed of 1GB Ethernet connection but it can be changed to Gb, 10Gb, fiber optic by adding a PCIe network card. They usually have a capacity range from 0-Unlimitied. The capacity varies because you can always add on hardware drive controller cards. You can have a board that has six SATA ports that can allow 30 drives to be attached and 3TB drives are used in RAID 50, then there would be 72TB of storage. When using RAID there aren’t really any fault tolerance. Older models of RAID have been known to lose all storage if one or more drives fail. When using a NAS device there are management features available like using SSL to protect the web management interface to bare minimum, also support of protocols such as SSH for encryption of RSYNC data transfers. SMB’s with more than two dozen users will appreciate a proper management console from which users and permissions can be managed. SMB’s that have deployed Active Directory will be looking for a NAS that supports it as well. Some models can switch off when not in use to save power and you can always play with the settings. NAS can be really helpful and can defiantly be helpful with a family that all has there own computer. With NAS you can have photos and videos and share them/access...

...THE ART OF CYBER WAR — ASYMMETRIC PAYOFFS LEAD TO MORE SPENDING ON PROTECTION 151 As Physical Security Converges With IT Security and Becomes More Network-Based, Can Cisco Compete? Cisco recently introduced new video surveillance IP cameras and monitoring software targeted for small businesses. As corporate security technology and services become increasingly network-delivered and database-driven, the physical security market presents a compelling incremental growth opportunity for Cisco that we believe can exceed the billion dollar annual revenue threshold in the next 35 years. The physical security industry has been undergoing a paradigm shift toward convergence, whereby previously disjointed functions of IT security and physical security are experiencing greater formal cooperation. Organizations continue to implement more IP-based video surveillance cameras and building access controls both to upgrade capabilities and to reduce operational costs. Deploying IP-based security upgrades capabilities and reduces operational costs. Through the IP network a security system can assign priority to data and automatically discover new nodes such as IP cameras and control sensors, eliminating the time and effort of manual provisioning. Shifting building access controls from isolated networks to existing IP networks that house data, voice, and video can improve incident detection and assessment, authenticating both the user and device to provide efficient integrity checks. • Video...

Shin kgshin@eecs.umich.edu The University of Michigan U.S. Of this, 65 TWh/year is consumed by PCs in enterprises, which constitutes 5% of the commercial building electricity consumption in the U.S. Moreover, market projections suggest that PCs will continue to be the dominant desktop computing platform, with over 125 million units shipping each year from 2009 through 2013 [15]. The usual approach to reducing PC energy wastage is to put computers to sleep when they are idle. However, the presence of the user makes this particularly challenging in a desktop computing environment. Users care about preserving long-running network connections (e.g., login sessions, IM presence, file sharing), background computation (e.g., syncing and automatic filing of new emails), and keeping their machine reachable even while it is idle. Putting a desktop PC to sleep is likely to cause disruption (e.g., broken connections), thereby having a negative impact on the user, who might then choose to disable the energy savings mechanism altogether. To reduce user disruption while still allowing machines to sleep, one approach has been to have a proxy on the network for a machine that is asleep [33]. However, this approach suffers from an inherent tradeoff between...

...for several years. However, in order to remain the innovative leader of its kind, the Greinly and Associates Consulting Group (GACG) has been asked to give some recommendations on how Information Technology can bring some improvements. The results of a conducted study of the patient information and medical records system indicted that a biometric known as Electronic Health Records (EHR) would drastically improve the timeliness and security of this process. A complete comprehensive study of the current antiquated system has been done. This study has allowed for the recommendations of how to implement the business and technical changes of the old system into the new EHR system to be brought forth. A theoretical analysis, backed by the research of previous and current projects with great similarities indicates that the implementation of the EHR system will drastically improve the hospital’s overall process of patient care. The end results being that there will be more satisfied and more loyal patients. 2.0 BRIEF COMPANY BACKGROUND Founded in 1990 by industrialists and the well-respected physician, George...

Communication devices are covered in detail in Tech Guide 4. The input devices accept data and instructions and convert them to a form that the computer can understand. The output devices present data in a form people can understand. The CPU manipulates the data and controls the tasks done by the other components. Primary storage (internal storage that is part of the CPU) temporarily stores data and program instructions during processing. Secondary storage (external storage such as flash drives) stores data and programs that have been saved for future use. Communication devices manage the flow of data from public networks (e.g., Internet, intranets) to the CPU, and from the CPU to networks. A schematic view of a computer system is shown in Figure TG1.1. REPRESENTING DATA, PICTURES, TIME, AND SIZE IN A COMPUTER ASCII.
