Explanation
Implementing dual, independent Fibre Channel fabrics is a key best practice for achieving High Availability (HA) in an FC storage environment.
Common mistakes.
- B. While a dual-port HBA is used to connect to dual fabrics, it is the existence of the dual fabrics themselves, not just the HBA, that constitutes the best practice for HA.
- C. A single HBA installed on a host represents a single point of failure and directly contradicts the principles of High Availability in an FC environment.
- D. A director-class switch offers high performance and scalability, but using a single switch still leaves a single point of failure for that fabric, making dual fabrics the overall best practice for HA.
