Multipathing is a technique used in computer storage systems to enhance data access and reliability. It allows multiple physical paths to connect a server to its storage devices, such as hard drives or storage area networks. This redundancy ensures that if one path fails, the system can still access the data through another path, minimizing downtime. In addition to improving reliability, multipathing can also boost performance. By distributing data requests across several paths, the system can balance the load, leading to faster data retrieval and better overall efficiency. This is particularly beneficial in environments with high data traffic, such as data centers.
