...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...

...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...

...NAS NAS devices are connected to the LAN as an independent network device and assigned an IP address. The primary advantage of NAS devices is that network storage is no longer limited to the storage capacity of a computing device or the number of disks in a local server. Many NAS products can hold enough disks to support RAID, and multiple NAS appliances can be attached to the network for storage expansion. There are many different types of NAS devices, ranges from beginners to experts. The features and specs will vary on the unit and manufacture. Because NAS are used for many different purposes, they come in wide storage range. They come in a large verity, anywhere from 10GB to 100TB. Depending on the Unit purchased, NAS has the ability to detect faulty drives and alert the end user of such failures. In those cases NAS also has the ability to hold Hot Swappable drives to replaces a bad drive without having to power down NAS. Also as a backup they will also support RAID 0 – 5. Speed on NAS units relay on different variables. For example, say you have a water pipe that provides water to your home. The main pipe that provides the water is 10in wide, however you home pipe that receives the water is only 1in wide. Although you have plenty of water coming in, you have only receive 10% of the incoming water. It is the same issue when dealing with NAS. NAS depends on the disk write speed and the connection on it. Some newer NAS will support SSD and will really be the best investment...

...Network Attached Storage (commonly abbreviated to NAS) are hard disk storage devices which you can connect to your home or office network. They enable multiple computers in a network to share the same storage space at once. Access to the NAS device is over a computer network (usually via TCP/IP) rather than being directly connected to the computer (as in internal hard drives or external USB/SCSI drives). The NAS devices are assigned an IP address and are accessed by clients (PCs or laptops) via a server that acts as a gateway to the data (this server is within the NAS device and hence NAS devices are often referred to as NAS servers). NAS devices speed is generally one gigabit Ethernet connection but this can be changed to multiple gigabits, 10 gigabit, and fiber optic by adding a PCI-e network card(s). The capacity range 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. NAS brings an extra level of fault tolerance to your network. Fault tolerant measures such as RAID prevent the NAS device from becoming a point of failure. NAS systems often contain more than one hard disk drive; they are arranged into logical, redundant storage containers or RAID arrays for added redundancy/security – thus, protecting data in the case of disk failure. RAID can be used on typical NAS devices. Management features are available with NAS. Reasons why users would want to...

...In Chapter 6 our class is learning about Network Attached Storage (NAS). This is a dedicated hard disk storage device that is set up with its own network address and provides file-based data storage services to other devices on the network (Rouse, 2013). Files can be accessed through the local area network using an IP (Internet Protocol) address. The NAS allows application programing and files to be served faster because there is no competition for processor resources (Rouse, 2013). According to CNET, the Synology DiskStation DS1513+ is the latest and top reviewed NAS on the market. This model includes the following specifications • 165.91 MB/sec Writing, 197.8 MB/sec Reading • Windows® ADS and ACL support • iSCSI Support as Virtualization Solution • Scale up to 15 Drives with Synology DX510 • Expandable RAM Size (up to 3GB) • 2 LAN with Failover and Link Aggregation Support • Hot-swappable Hard Drive Design Management includes: DSM Upgrade; Email Notification; SMS Notification; Customized User Quota; DDNS Support; PPPo; Resource Monitor; UPS Management; Multiple Scheduled Power On/Off; and Custom Management UI HTTP/HTTPS Ports. This device supports 4 different browsers, 3 different operating system types, had HDD Hibernation management as well as S.M.A.R.T. management, many Network Protocols and Volume Management, tons of security and is multi-lingual with about 20 languages to choose from.

...Network Attached Storage A “NAS” device, or network attached storage, is a computer that stores and shares files through a network instead of a hard cable. It shares files with other computers through the air the same way wi-fi sends an internet connection through the air. This method of file sharing is ideal for the workplace such as, corporate offices, small offices, or even small businesses like restaurants where mass storage needs to be shared between many computers. Here I will provide more specifics about network attached storage devices, such as communication speed, capacity, fault tolerance, and management capabilities. When dealing with communication speed we must look and the size of information being transferred. Typically, the regular communication speed is a 1 gigabit Ethernet connection but, this can be changed to multiple gigabit. It is hard to say what the max capacity of a network attached storage device is because there are many different adapters that can be used to add on more storage. After doing some research, the biggest set up I found was 72 terabytes. This was done using a 1 to 5 port replicator on a board with 6 SATA ports. Fault tolerance is important because it is how you set up your boards in case a drive fails. The raid 50 set up is one of the most common set ups but raid 10 is the most reliable. No management capabilities were found at this time. One question I was asked was what would be an advantage of all family photos and videos being stored...

...Network Attached Storage A NAS (network attached storage) is a system consisting of 1 or more hard drives. This system connects your home or business network and allow those with access to share files from a central location. Long before social networking sites and cloud storage systems, there was a need for a central memory storage locations for homes and businesses. Think of the NAS as a physical central cloud that would make it easier to share files from one computer to the next with no need for emailing or having to physical transfer the file via a flash drive or CD. The NAS would be connected to the network via either an Ethernet cable or wireless connection. The speed of the network access is all based on the type of connection to it. An Ethernet connection would provide a speed up to 1GB, while a fiber optic connection with a PCIe network card would provide up to a 10GB connection speed. The capacity (storage space) varies vastly on the amount of space and the hardware that you are using in conjunction with the NAS. In conclusion there is an infinite amount of storage space available with a NAS. The NAS uses a RAID storage back up system depended on how many drives are attached to it. It could support up to a RAID 50 back up system. Its always best to use a some sort of encryption along side the NAS and to keep the internet connection of the NAS down to a minimum. Another ability of the NAS is the ability to establish a management and access control system so only...

...Network Attached Storage (NAS) is a dedicated network device that provides affordable, easy access to data by utilizing computer networks for data storage. NAS is more affordable compared to the traditional central file server and thus allows homes and businesses to store and retrieve large amounts of data. Although file servers boast a successful track record, most homes, small businesses, and workgroups cannot justify dedicating the money and resources to a general-purpose computer to simple data storage tasks. Enter NAS. The speed in which NAS devices access the network will greatly depend upon whether the user builds the device themselves or buys a pre-built system. A 1 gigabit Ethernet connection is the usual speed for an NAS but this can be increased up to 10 gigabit or fiber optics for even faster speeds by simply adding a PCI Express network card(s). NAS storage capacities will also vary based upon the user’s needs as well as whether the system is purchased pre-built or a do-it-yourself system. By adding hardware drive controller cards and port replication, there is theoretically no limit on storage size. For example, a user could achieve 72TB of storage by using a motherboard with six SATA ports with replication allowing for a total of thirty drives being attached, and setup in a RAID 50 configuration using 3TB drives. NAS devices do have fault tolerance built into them. RAID 10 is considered the best setup as it allows for more drives to fail and still allow...

NAS operates as a file server, and can be specialized for tasks in either hardware, software, or configuration of those elements. NAS is manufactured as a computer appliance a specialized computer that can be built from the ground up for storing files, other than simply using a general purpose computer for it. The speed of a Network adapter is commonly one gigabit Ethernet connection but can also be changed to multiple gigabit, depending on if you’re building it yourself or buying it from a vender. The capacity range vary, some people have built 40 TB machines while other have 2TB. Port replication and the add-on hard drive controller cards, there can’t really be a limit on size. Say for example a board with 6 SATA ports can be replicated allowing for 30 drives to be attached, if 3TB drives were used in raid 50 that would be 72TB of storage. Fault tolerance, on the NAS device there is RAID 50 which is fairly stable if one set it up correctly. RAID 10 is one of the best setups, with RAID more drives can fail at once without data loss. All of those features can be used on any common NAS device. To put it simply, yes there are management features available to NAS, and a lot of them might I add. Why would a user want to use NAS? Well since NAS helps speed up processing and all that fun stuff who wouldn’t? Faster processing speeds means...

...xample apparatus and methods concern a file system based interface between a disk-based network attached storage device and a linear tape open (LTO) linear tape file system tape. One example method may include controlling a device (e.g., backup server) to read a file from the NAS device using a shared file system (e.g., NFS, CIFS) and controlling the device to write the file to the LTO tape device using the LTFS. Since the NAS device and the LTO device may have different information or metadata requirements, and since the shared file system and the LTFS may have different information or metadata requirements, the method may include controlling the device to remove from the file information specific to the NAS and the shared file system. Additionally, the method may include controlling the device to add to the file information specific to the LTFS or the LTO device. Inventors: Wideman, Roderick B. (Shakopee, MN, US) Claim: 1. A computerized method, comprising: accessing a shared file system on a network attached storage (NAS) disk-based device; accessing a tape file system on a linear tape open (LTO) tape-based device; and exchanging a file between the shared file system and the linear tape file system using a file system based approach throughout the exchange, where exchanging the file includes reading the file from a mounted shared file system volume on the NAS device using the shared file system, and providing the file to a linear tape file system (LTFS) volume on the LTO...

...October 27, 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...

...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/...
