Network Attached Storage - an indepth guide

A Network Attached Storage (NAS) is a form of storage space system which can be connected to a data network. A NAS is effective for storage relevant to non mission-critical files. It is more affordable and simpler to look after over a Storage Area Network (SAN) but won't quite deliver the performance a good enterprise can acquire from a SAN.

File transfer protocols supported by NAS consist of Network File System, Common Internet File System, File Transfer Protocol, etc. NAS servers give versatility in terms of attachment to the network; this can be accomplished either via the Ethernet or a fiber channel network. Nowadays it's also possible to get wireless 802.11 NAS devices. The good thing about NAS devices is in their simpleness, they are often constructed using any kind of drive technology though they're usually developed using Small Computer Systems Interface (SCSI). NAS devices may also be used for many other storage methods like magnetic tape, CD, and DVD.

NAS supplies the following benefits -

1.Faster access to saved data via the LAN.

2.Low costs because the RAID arrays are a part of the LAN.

3.Simple to set up, is generally working in under thirty minutes.

These kinds of properties of NAS storage plus its low-cost of ownership make it perfect for SMBs. A dual benefit of Raid 5 NAS is the fact that it permits administrators either to improve or consolidate the storage infrastructure. Storage expansion is essentially unlimited as one is free of the limitation of storage capabilities of individual servers and the amount of hard disks they can hold. At the same time, one NAS set-up is good enough to replace several data file servers that are working separately, this can lead to consolidation. NAS can be run using commonly accessible operating systems for example Windows. NAS status could be checked out from anywhere on the LAN, thus giving storage administrators a chance to identify problems and change NAS configurations when needed.

NAS system performance is determined by the drive support, the number of hard drives being used and also the overall capacity. SATA drives that provide outstanding low-cost mass storage tend to be most recommended. SCSI disks are also offered. Since the NAS makes use of the LAN for data transfer there's always a chance of a bottleneck developing some time over the LAN, normally it is the network interface that causes issues. If utilizing a NAS, search for products which support Gigabit Ethernet for quick data transfer as well as several connections so that network load is spread and interface redundancy is supplied.

When selecting a NAS solution keep security in mind and look for vendors that provide native encryption using the system.
