Those two technologies have nothing incomon except for the fact that both address mass storages. RAID is a technology to span data over multiple disks to either gain more speed (seldom e.g. RAID0) or gain redundancy so that the system remains functional when one of the mass storages fail (e.g. RAID1 or RAID5). SAN means that there is a dedicated network instead of a local bus connecting the hostadapter to the storage. These networks use often similar protocol as on a local buses (e.g. iSCSI). Data is not aqured on a file per file base like in a server instead the host requests the specific blocks he would like to read. Advantages of a SAN may be fast switch over of mass storages from one Node to an other (storage failover if a node fails), storage sharing (one big disk [might even be a RAID system] is split up into two or more "virtual" disks which are then handeled by the respective node) or a centralized fast access for backup storages. Important thing to know is: both technologies may be (and are often) combined to get the best of both worlds.

What is the purpose of network attached storage raid?

Network Attached Storage is short for NAS, which is computer storage connect to a network. RAID is a hard drive or storage container, which provide access to the file network.


How does NAS Raid storage even work?

NAS Raid storage works by connecting computers to the NAS storage hard drive and allowing them to share information via the ethernet network connection.


What is NAS storage?

Network Attached Storage. The word "storage" in the question is redundant, as the S in NAS is "Storage" It's an enclosure holding a large amount of RAID disk storage, which is directly attached to the network. The NAS does not need a decicated computer system to run it, as the enclosure contains the network interface card (or cards if it is connected to multiple network ports), and all of the required control circuitry.


How do you setup a RAID network?

I'm not really sure what you really mean. You can set up a RAID array, but not a network that only consists of RAID. However, you can set a cluster NAS server which can utilize RAID arrays. However, RAID is never a substitute for backups, as with RAID arrays each storage device you add creates an additional point of failure - and in cases like RAID level 0 (striping), you will lose everything if even one drive fails.


What exactly does the term raid data recovery refer to?

"RAID" is short for "Redundant Array of Inexpensive Disks." RAID are groups of storage systems. RAID Recovery is the act of recovering data from those storage systems.

What does the term raid server recovery mean?

The term "RAID server recovery" means just that: recovery of the RAID server. A RAID server is a computer that runs RAID software to act as a secondary storage.


How are raid levels determined?

Raid Levels are determined by MTTF/number. To determine the raid levels one should reference the standard raid levels and determine what raid level your data storage capacity needs.


Is it safe for someone to use Raid in storage units?

It depends on the type of Raid being used. Raid Max Bug Barrier Pesticide is one formula that is designed to be used inside the home and in cabinets or other storage areas safely. Raid House and Garden Bug Killer is safe to use in general storage areas, but not near edibles and is not safe for pets to be exposed.
