Question 4 of 30
4. Question
What are some best practices for implementing zoning and masking in SAN management?
Correct
Implementing zoning and masking are essential aspects of SAN (Storage Area Network) management aimed at enhancing security and controlling access to storage resources. One of the best practices in SAN management is configuring LUN (Logical Unit Number) masking, which involves restricting access to specific LUNs based on the WWN (World Wide Name) of hosts or initiators. By implementing LUN masking, organizations can ensure that only authorized hosts or initiators have access to the designated storage resources, thereby preventing unauthorized access or data breaches. This practice enhances data security and compliance with regulatory requirements such as PCI DSS or HIPAA, which mandate strict access controls for sensitive data stored on SANs. Additionally, LUN masking helps in optimizing resource utilization by allocating storage resources only to the necessary hosts or applications, thus improving overall SAN performance and efficiency.
