Which of the following is BEST described as a storage system that can be connected to multiple servers through a fiber channel?

• A. JBOD
• B. SAN
• C. DAS
• D. NAS

Answer: (B)

The best choice is a storage area network (SAN), which is designed specifically for connecting multiple servers to a centralized storage system through high-speed connections, typically using fiber channel technology. A SAN allows for efficient data management and high availability, as it creates a dedicated network for storage, separating it from regular network traffic.

In contrast, a JBOD (Just a Bunch of Disks) is simply a collection of hard drives that may not necessarily be managed as a unified system and does not inherently involve multiple servers connecting through fiber channel. Direct Attached Storage (DAS) connects directly to a single server, making it unsuitable for environments requiring shared storage across multiple servers. Network Attached Storage (NAS) provides file-level data storage and typically connects through standard network protocols like Ethernet rather than fiber channel, making it less optimized for server connectivity compared to a SAN.

Thus, the architectural structure and function of a SAN make it the ideal solution for environments where multiple servers require high-speed access to a shared storage system.
