Network attached storage, otherwise known as NAS storage, is a file server that is built primarily for the purposes of storage. Rather than being a server that must perform multiple tasks, these are adept at being your perfect storage solution because they offer faster data transfer, easier and better administration as well as the relative simplicity of keeping them running. These servers usually come in rackmount varieties that can be stacked to create a serious amount of storage. Enterprise level individual servers typically offer 1, 2, 4 and 8 terabyte models and utilise different software such as Microsoft Server to intelligently manage your servers functions while also aiming to maintain access and write speeds. This is coupled with drives in a RAID configuration of level 0, 1, 5, 6, 10, 50 and 60. NAS storage options like this will also naturally yield a high level of fault tolerance and management options that can yield an unprecedented level of flexibility both in terms of software and hardware.
ISCSI storage is interlinked with NAS. It stands for Internet Small Computer System Interface which means that SCSI commands can be sent over IP networks which instantly means that they can be accessed over Intranet and Internet. Of course, being able to access these functions from the Internet can offer many different possibilities when it comes to file storage on the go. With ISCSI storage you will no longer have to worry about data storage problems, particularly since the virtually attached disks will be able to respond very quickly as if it was actually attached to your machine. All you require is an existing network infrastructure to take advantage of the possibilities that ISCSI offers. Both NAS and ISCSI can be offered simultaneously with the same server, meaning that you have many different storage options at your disposal.
