NAS storage can take many forms . For example, other servers, virtual machines or so-called disk stations can be connected to the operational server, in which a different number of removable hard disks are located. These can be arranged as one larger unit or as a RAID array . In this case, the data is stored simultaneously on two or more independent disks in a specific way, so that if one of them fails, it will not be lost. In practice, the designation of the RAID array is used together with a number that expresses the level of security.
For example, RAID has a higher level of data security USA Phone Number List than RAID . Protocols for remote access to files via the Internet are used to communicate between the server and NAS storage . Among the most common are NFS (Network File System), which is suitable for Linux systems, or SMB (Server Message Block), which is used for Windows. SAN and DAS, or Block-oriented storage Block-oriented repositories can also be divided into two subcategories depending on how they are connected to the server.
The first possibility is that it is a so-called DAS (Direct Attached Storage), which is directly connected to the server. In the second case, disk arrays and storage are connected via a dedicated data network, which is called a SAN (Storage Area Network). For example, hard drives, SSDs or even disk arrays can serve as DAS. These storages are connected in different ways - SAS or SATA are commonly used . DAS can be very powerful and often cheaper than SAN. But the downside is that DAS cannot be easily expanded. The number of connected computers is number of SAS ports on the DAS. In the case of disk arrays, the usual number is four. That is why many companies and institutions prefer to choose block-oriented storage connected via SAN.
