What type of network is dedicated to interconnecting storage devices with high speed and redundancy?

A storage area network (SAN) is specifically designed to connect storage devices to servers in a way that optimizes performance and provides redundancy. It operates at a high speed, ensuring efficient data transfer between the storage devices and the systems that need to access that data. Unlike a local area network (LAN) that connects computers within a limited geographic area or a wide area network (WAN) that spans larger distances, a SAN is tailored for storage needs, allowing for block-level storage and providing features like data replication and high availability.

This dedicated network offers advanced capabilities like failover and load balancing, which are crucial for maintaining uptime and ensuring data integrity. Additionally, SANs are often used to facilitate the storage of large volumes of data and manage backups and recovery processes efficiently.

In contrast, a virtual private network (VPN) focuses on secure communication over the internet, connecting remote users or sites to a private network, which does not pertain to storage device interconnectivity. Thus, the characteristics of SAN make it the correct answer for the question posed.
