What Is Nsa Device
NETWORK ATTACHMENT STORAGE Renika L. Whaley NT1110 Mr Dameon Hagler What is a NAS device? A NAS is hard disk storage that is set up with its own network address rather than being attached to the department computer that is serving applications to a network’s workstation. 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; 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. Is there any fault tolerance (such RAID) built into a NAS device? As fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 has been touted as one of the best setups since more drives can fail at one time without data loss.
All of those features can be used on typical NAS devices. Are management features available? Yes Speculate on why a user would want to use a NAS. For example, what would be the advantage of all family photos and videos being stored on a NAS in a family where the parents and children all had their own computers? NAS is network allocated storage apart from any other systems attached to the network. There are a lot of considerations: 1. Power usage. All users may shutdown their computers. Some people build NAS from atom boards and other things for their low power characteristics. ) 2. Always on availability. As long as the network is up and the NAS is functioning, it is always available regardless of what computers are on/off the network. 3. Centralized Storage for backup. If a computer needs to be rebuilt or wiped, you can push files and backups and restore from the same location. 4. Cost effective. Installing a RAID 1 in each computer (Mirror drive) would cost more and use more storage than perhaps a RAID 5 in the NAS with multiple PC’s.
This may apply more to offices than for example a small home with 2-3 PC’s. 5. Redundancy. Most personal computers operate a single drive (cost consideration) or on performance considerations (RAID 0 etc. ) more so than reliability. NAS are typically setup for redundancy in case of drive failure (RAID 1,5,6 and the various permutations. ) 6. Lower priority data. This doesn’t always apply, but lower priority data can be moved to another location (for example, VM Images). They take up storage space, but a user may not want this to take up higher priority space.
