A mission-critical server with a dual-port HBA is used in a highly available SAN environment. The SAN administrator has been advised this server has a single point of failure. Which of the following a

Creating a server cluster addresses application availability and performance across multiple servers but does not eliminate the single point of failure within the SAN connectivity of the original server.

Purchasing additional switches creates a redundant SAN fabric, which is good for overall SAN availability, but it does not address the lack of HBA redundancy within the server itself.

A single HBA, even with multiple ports, represents a single point of failure for server connectivity to the SAN. Installing a second HBA and distributing the SAN connections across both HBAs ensures that if one HBA fails, the server can still access storage through the other, maintaining high availability.

Partitioning storage resources with one partition per fabric relates to LUN management or zoning and does not directly resolve a single point of failure in the server's HBA.
