Server Nas

What is the use of the server or NAS?

NAS (Network Attached Storage) will be used as a high-perfomance server and storage. Network connection Storage (NAS in general) will be calculated generally in the system, reducing the storage device accessible via a computer network (usually TCP / IP) instead of the computer is directly connected to the SCSI bus, such as computer (via). This allows multiple computers at once, to minimize the administrative overhead in the center of the hard disk, you can share the same storage area. NAS systems are usually one or more hard disk one is often a logical redundant storage containers or RAID arrays are deployed. Using NFS NAS protocols are based on files and protocols such as Microsoft Common Internet File (CIFS). In reality, NetApp for NAS devices, EMC's Celerra device and is, Data ONTAP on devices such as the DART is a tiny operating system. Storage Except, generally using Purotokoruburokkubesu area network that is run through a separate dedicated storage network (SAN) are very similar. NAS devices is the logical file system Storage for local area network. Therefore, NAS device performance significantly, the cache memory of RAM (equivalent), and network overhead, the router (depending on the speed of the network Card). The advantage is you can get your entire hard drive to build a huge area of the device. The disadvantage is that slow access to the results of any narrowing of the local network Time. NAS efforts to manage and maintain "server farms" necessity was developed to address the issue of direct-attached storage and include lack of scalability and Reliability, availability, and performance. They provide heterogeneous data sharing can be achieved much easier to use, automating the organization can simplify data management. In In addition, NAS appliance prices in recent years, the home offers a flexible network is almost a normal USB or Firewire-based storage has plummeted more than the cost of external Is hard.
