Device Mapper Multipathing (DM-Multipath)

Device Mapper Multipathing (DM-Multipath) is a technology used in computer storage systems to create multiple data paths between a server and storage devices. This setup ensures that if one path fails or becomes slow, data can still flow seamlessly through alternative paths, enhancing reliability and performance. Think of it like having multiple roads to a destination: if one road is blocked, traffic can be rerouted without interruptions. DM-Multipath manages these pathways automatically, providing redundancy and ensuring continuous data access in complex storage environments.
