When integrating a new storage array into an existing SAN infrastructure with HPE C-Class blade enclosures and a mix of ProLiant G7, Gen8, and Gen9 servers, it is essential to ensure firmware compatibility across all components. The best approach is to document all relevant details about the existing servers and SAN environment, including firmware versions, hardware configurations, and any specific SAN components. Then, consult the HPE SPOCK (Single Point of Connectivity Knowledge) database, which is the authoritative source for compatibility and support information regarding firmware, drivers, and hardware in HPE environments. This ensures that the new storage array will be fully compatible with the existing infrastructure, preventing potential issues related to firmware mismatches.
