While it may not seem to the average user that there’s an operating system that manages the storage device, NAS devices have to have an OS on them to take care of the tasks that would otherwise be managed by a computer for DAS devices. The operating system is also needed to run the wide variety of applications available on NAS devices:
A network-attached storage (NAS) device is a data storage device that connects to and is accessed through a network, instead of connecting directly to a computer. NAS devices contain a processor and operating system so it can run applications and provide the intelligence needed for files to be easily shared by authorized people.
***The Internet Storage Name Service (iSNS) protocol is used to automatically discover, manage, and configure iSCSI devices on a TCP/IP network. iSNS is used to emulate Fibre Channel fabric services to provide a consolidated configuration point for an entire storage network.
How a NAS device works. Your computer will read data from and write (store data) to DAS devices faster than network devices. Depending on the size of your files and what you’re trying to do, you may notice a difference. Editing large photos or videos, working with complex design documents, or transferring very large files are examples ...
Usually, with hard disk drives, the primary function of a NAS device is to store your files. The most popular NAS devices for home office, small business, ...
Networking. This is how the NAS device is connected to your computer (s). The network attachment can be via ethernet cable (hardwired) or Wi-Fi. While many NAS devices contain USB ports, these ports are not used to connect the NAS device to your computer—these USB ports are for connecting other devices to your NAS device, whether for charging, ...
A network-attached storage (NAS) device is a data storage device that connects to and is accessed through a network, instead of connecting directly to a computer. NAS devices contain a processor and operating system so it can run applications and provide the intelligence needed for files to be easily shared by authorized people.
The beauty of a NAS device is that it can be easily accessed by multiple people, multiple computers, mobile devices, or even remotely (if set up properly). Directly to your computer. This is what most of us do at home when we need more storage than our computer or laptop holds. Most often, you’d use a USB cable to connect a hard drive ...
NAS devices contain a CPU of some kind since it takes computing intelligence and power to manage the filesystem, read and write operations, run applications, process multimedia files (such as video), manage multiple users, and integrate with the cloud if desired. Operating System .
