What is the best approach to connect a server to a SAN while ensuring availability and access control?

1. Install a single port HBA and create a LUN

2. Install a dual port HBA and enable basic multipath

3. Install a dual port HBA, create a LUN, and enable LUN masking and multipath

4. Connect the server directly without any additional hardware

The correct answer is: Install a dual port HBA, create a LUN, and enable LUN masking and multipath

The best approach to connect a server to a SAN while ensuring availability and access control involves several critical factors, including redundancy, data accessibility, and security measures. By installing a dual port Host Bus Adapter (HBA), you create a connection to the SAN that supports redundancy. This design mitigates the risk of a single point of failure; if one port fails, the other can seamlessly maintain connectivity. Creating a Logical Unit Number (LUN) allows the server to access a defined portion of the SAN's storage resources. This is essential for organizing and managing data efficiently. Furthermore, enabling LUN masking adds a layer of access control by allowing only specific servers to access designated LUNs. This enhances security by preventing unauthorized access to sensitive data stored on the SAN. Implementing multipath I/O provides additional pathways for data transmission between the server and the SAN. This not only improves performance by balancing loads but also increases availability since alternate data routes can be utilized if one becomes unavailable. In summary, by incorporating a dual port HBA, creating LUNs, and applying both LUN masking and multipath, the server is optimally connected to the SAN with robust availability and strict access control measures in place. Each component of this approach is crucial for maintaining
