...NAS: What is a NAS device? A network attached storage (NAS) is a computer connected to a network that provides only file-based data storage services to other devices on the network. It does not only operate as a file server but is specialized for the task either by its hardware, software, or configuration of those elements. It’s 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. What is the speed of the network adapter available on a NAS device? The speed is typically one gigabit Ethernet connection but this can be changed to multiple gigabit, 10 gigabit, fiber optic by adding a pci-e network card(s). Older parts can be used which may be limited to 10/100 megabit. If you need an exact answer for speed, simply look at the wiki on gigabit. What is the capacity range? The capacity range again varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and add-on hard drive controller cards there is hardly a limit on size. A board with 6 sata ports can be replicated (1 to 5 port) allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage. Is there any fault tolerance (such as RAID) built into a NAS device? Yes there is depending on which type you have. There are 3 main configuration types of NAS box; 1 disk boxes, 2 disk boxes and 4 disk boxes. The...

...Research Paper 1: Network Attached Storage (NAS) What is a NAS device? What is the speed of the network adapter available on a NAS device? What is the capacity range? Is there any fault tolerance (such as RAID) build into a NAS device? Are management features available? These are the questions I have to answer for this paper. So, here are my results starting with the first question. What is a NAS device? Network Attached Storage is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users and heterogeneous clients. Seems to me that a NAS is like a WIFI version of an external hard drive. Though, if needing more room, you can add another to the one you already have. What is the speed of the network adapter available on a NAS device? NAS device doesn’t require much processing power. The largest bottleneck in performance will most likely be the network itself. Most home networks will use wired fast Ethernet (100 Megabits/sec), wired gigabit Ethernet (1000 Megabits/sec), wireless g (54 Megabits/sec), or wireless n (248 Megabits/second). What is the capacity range? Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions. A 160GB capacity for example would be enough storage for around 40,000 average audio tracks or up to 200 hours of video content. If you'll be using your NAS device to store masses...

...Network Attached Storage (NAS) A Network-attached storage (NAS) is a server that is dedicated to nothing more than file sharing on a network. NAS does not provide any of the activities that a server in a server-centric system typically provides, such as e-mail, authentication or file management. It 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 a vital part of the server. The server handles all of the processing of data but a NAS device delivers the data to the user. It does not need to be located within the server, but can exist anywhere in a LAN and can be made up of multiple NAS devices. (QuinStreet Enterprise , 2014) The speed of the network adapter on a NAS device can vary, depending on which one you buy. Your typical NAS device can run from 10 Mbps all the way to 1000 Mbps. The capacity range for a NAS device can range from a 1 TB all the way to 20 TB. This is 20,480 MB worth of data storage! With this large amount of data storage, you could store all your music, pictures, and videos in one device. (Best Buy, 2014) NAS Devices come with a built in fault tolerance called a RAID. RAID stands for “redundant array of independent disks”. With the help of RAID, you can tap into all of the storages on a NAS device all at once. A RAID array not only allows you to combine physical drives into a single storage unit, it also reserves a part of this...

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...

...Network Attached Storage Network Attached Storage (NAS) is a dedicated hard drive which is set up with its own network address and provides file-level data storage services to other devices on the network. It allows both programming and files to be served faster because they are not competing for processor resources. NAS usually configured with a web browser and do not require a keyboard, mouse or monitor. Unlike other external hard drives, NAS has a processor. Some NAS devices will run using standard operating system like MS Windows, many other NAS devices use their own proprietary operating system. A NAS can store any data that appears in form of files, including email boxes, Web content, remote system backups, etc… Overall the use of a NAS parallels those traditional file servers. NAS devices come in many varieties depending on you build it or purchase it from a vendor. The speed is usually 1GB Ethernet connection but it can be changed to multiple GB to 10GB, fiber optic by adding PCI-e network cards. The capacity range also can be varied. If you have a port replication and add-on hardware drive controller cards, there really isn’t a limit on size. For example: if you have a board with 6 SATA ports which can be replicated (1 to 5 port) allowing 30 drives to be attached. Then if 3TB drives were used in RAID 50 that would be 72TB of storage capacity. As far as fault tolerance, RAID 50 can be quite stable if it’s set-up correctly. While RAID 10 is one of the best set-ups...

...company. To do this a backup server would be the way to go. There are several ways to do this one would be to install a NAS or use a Server to make sure the data is backed up. A NAS unit is a computer connected to a network that provides only file-based data storage services to other devices on the network. Although it may technically be possible to run other software on a NAS unit, it is not designed to be a general purpose server. For example, NAS units usually do not have a keyboard or display, and are controlled and configured over the network, often using a browser. A full-featured operating system is not needed on a NAS device, so often a stripped-down operating system is used. For example, FreeNAS, an open source NAS solution designed for commodity PC hardware, is implemented as a stripped-down version of FreeBSD. NAS systems contain one or more hard drives, often arranged into logical, redundant storage containers or RAID. NAS uses file-based protocols such as NFS, SMB/CIFS, AFP, or NCP. NAS units rarely limit clients to a single protocol. NAS is useful for more than just general centralized storage provided to client computers in environments with large amounts of data. NAS can enable simpler and lower cost systems such as load-balancing and fault-tolerant email and web server systems by providing storage services. The potential emerging market for NAS is the consumer market where there is a large amount of multi-media data. Such consumer market appliances are now commonly...

...Kevin Wingate November 10, 2014 NT1110 – Computer Structure and Logic Research Project – Network Attached Storage A Network Attached Storage (NAS) device is a device connected to a network of two or more computer with the purposes of providing “community storage” of files and other data. As our society moves closer towards greater mobility the need to have mobile storage has increased. There are many types of storage devices, with various advantages and disadvantages to each of them; including Direct Attached Storage (DAS) and Network Attached Storage Devices. NAS devices are useful if all the computers on the network need access to the same files, DAS can only be accessed by the computer they are attached to (unless the computer grants access to another user. Most NAS devices contain multiple hard drives, which are connected by an internal server. There are many features of NAS devices. The speed of the network is dependent on the service available to the network and the number of users on the network. The capacity range of the network is depend on the hard drives contained in the device and the way it is setup. As with most servers or combination of two or more hard drives (Redundant Array of Independent Disks) RAID can be set up to maximize the use of the server and to protect the data. Also most NAS devices have software, which can be installed on client computers which allows the user to manage the device. The device has an IP address which also allows you...

...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/...

...NT1110 Network Attached Storage NAS stands for Network Attached Storage. It is a file server connected to a computer network. NAS only provides file based data storage. With a NAS device the server handles the processing of data but NAS delivers the data. This helps your network to run quicker and smoother. NAS gives more hard disk storage without having to shut down for maintenance or upgrades. It doesn’t even need to be attached within the server; it can function anywhere in a LAN (local area network) and can have multiple networked NAS devices. It is a convenient way to share files. These devices contain one or more hard drives and can store a large amount of data. It is quick and easy to use. They provide faster data access and simple configuration compared to file servers. Another advantage is data protection. Disk failures happen every day. NAS will keep important files (family photos, documents, etc.) safe. Some NAS systems can even share a printer, act as a media streamer or even a surveillance system by supporting IP cameras. NAS systems are networked storage containers or RAID (storing data in different places). They essentially are mini computers used to design to store and share files. They don’t have a keyboard or display but do have specialized hardware and software with a stripped down operating system like FreeNAS, and usually have ARM, PowerPC or MIPS processors. The speed of a NAS device varies depending on which NAS device you’re using. It also...

...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...

...Research Paper on NAS Devices What is a NAS device? We all know we can connect a USB External Hard Drive to our computer and immediately create additional storage for data or backup, but when it comes to efficient data management, there is perhaps a better way… to use Network Attached Storage or NAS for short. What is the speed of the network adapter available on a NAS device? There are many varieties of NAS devices, depending on if you build it yourself or purchase it. 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. What is the capacity range? Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions. A 160GB capacity for example would be enough storage for around 40,000 average audio tracks or up to 200 hours of video content. If you'll be using your NAS device to store masses of content, including High Definition content, or indeed backing up multiple user's PCs, you'll need a bigger capacity. Is there any fault tolerance (such as RAID0 built into a NAS device? If set up correctly RAID 50 is fairly stable, RAID 10 has been touted as on of the best set ups because more drives can fail at one time with having data loss. Are management features available?

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.[nb 1] As of 2010 NAS devices are gaining popularity, as a convenient method of sharing files among multiple computers.[1] Potential benefits of network-attached storage, compared to file servers, include faster data access, easier administration, and simple configuration.[2] NAS systems are networked appliances which contain one or more hard drives, often arranged into logical, redundant storage containers or RAID. Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. Note that hard drives with "NAS" in their name are functionally similar to other drives but may have different firmware, vibration tolerance, or power dissipation to make them more suitable for use in RAID arrays, which are sometimes used in NAS implementations.[3] For example, some NAS versions of drives support a command extension to allow extended error...

...the Availability Digest Towards Zero Downtime: High Availability Blueprints August 2007 Vishal Rupani focuses on Microsoft Clustering in his very readable book, Towards Zero 1 Downtime: High Availability Blueprints. He first provides a high-level overview of many topics pertinent to high availability. He then devotes most of his book to Microsoft Clustering and to the proper installation of Microsoft’s Cluster Server and several of Microsoft’s cluster-aware applications. He follows this with a brief discussion of disaster-tolerant architectures, and concludes with a case study. High-Availability Topics Rupani begins with a definition of several high-availability concepts, such as planned and unplanned outages, single points of failure, mean time between failures and interruptions, fault tolerance, and redundancy. He then provides an overview of several important high-availability technologies. RAID RAID technology is the most common method to provide data resiliency. With RAID (Redundant Arrays of Independent Disks), data is redundantly stored on multiple disks such that, should one disk fail, the data can still be reconstructed. RAID arrays typically provide a hot-swappable capability so that a failed disk can be replaced without taking down the array. There are several configurations of RAID. Most stripe data across multiple disks to achieve improved performance. Mirrored disks, used by fault-tolerant systems and designated as RAID 1, provide an...
