We took the best elements of Windows 10 and refined them to create a soothing place to work and play. Windows 11 is easier on the eyes and easier to use. They connect shared storage arrays and tape libraries to multiple servers used by clustered servers for failover.Comparing features between Windows 10 Home vs. Today's SANs create new methods of attaching storage to servers, enabling high availability and performance improvements. This layer ensures secure and robust data transfers. A SAN also includes a management layer that organizes the connections, storage elements and computer systems. This concept enables storage devices and servers to interconnect by using similar elements, such as local area networks (LANs) and wide-area networks (WANs). The SAN can also be viewed as an extension of the storage bus concept. Sometimes referred to as the network behind the servers, a SAN consists of a communication infrastructure, which provides physical connections, allowing an any-to-any device to bridge across the network using interconnected elements, such as switches and directors. ![]() Introduction to Storage Area Networks (11.6 MB) SANs simplify management by creating single images of storage media. SANs protect data from disaster and malicious attacks with a remote copy. ![]() SANs make simpler management, scalability, flexibility and high availability possible. SANs offload and move storage processing from servers onto separate networks. Storage exists independently of applications, and it's accessible through multiple paths for increased reliability, availability and serviceability. SANs also allow multiple hosts to access multiple storage devices connected to the same network in new network architectures. ![]() But organizations can use any network file systems (NFS) appropriate for their infrastructures. Typically using block-level storage systems, SANs allow data-moving applications to perform better by transmitting data directly from the source to the target with little server intervention. ![]() The SAN also centralizes storage devices and the clustering of servers, potentially achieving easier and inexpensive centralized administration, lowering the total cost of ownership. It attaches storage directly to the network, so storage is externalized and functionally distributed across the organization. The SAN frees the storage device so that it isn't on a particular server bus. The storage utility might also be located far from the servers that it uses. A SAN eliminates single points of failure to enhance storage reliability and availability.Ī SAN is also optimal for disaster recovery (DR) because a network might include many storage devices, including disk, magnetic tape and optical storage. The SAN eliminates the traditional dedicated connection between a network file server and storage - and the concept that the server effectively owns and manages the storage devices - eliminating bandwidth bottlenecks. But a SAN introduces networking flexibility enabling one server, or many heterogeneous servers across multiple data centers, to share a common storage utility. Traditionally, only a limited number of storage devices could attach to a server, limiting a network's storage capacity. So, most organizations employ some form of a SAN in addition to network-attached storage (NAS) for improved efficiency and better data management. Computer memory and local storage resources might not provide enough storage, storage protection, multiple-user access, or speed and performance for enterprise applications. ![]()
