NAS DEVICES

Hello, I am doing an assignment and I cant seem to find the answer anywhere online maybe I could get some help here. What is the speed of the network adapter available on a NAS device? What is the capacity range? Is there fault tolerance built into a NAS device. Are management features available?

NAS devices come in many varieties depending on if you build it yourself or purchase a vendor product. 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.

The capacity range again varies, people have built 40 TB (terabyte) machines and other just have 2TB. With port replication and addon 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.

As far 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.

Here is a typical management feature youtube rundown of FreeNAS 7, it covers the basic controls through a webpage.

Same exact thing happened in our class. Our teacher got a "real job" at some company, so we got a new teacher who is... well, pretty much like you said.

hey can u help answer this question?

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.
