To confirm that a new storage array will be supported in an existing environment that includes HPE C-class Blade Enclosures and a mix of ProLiant G7, Gen8, and Gen9 servers, the correct approach is to document the existing server and SAN information and consult the HPE SPOCK (Single Point of Connectivity Knowledge) tool. SPOCK is an HPE resource that provides detailed compatibility information for various HPE products, including firmware and software compatibility matrices. This ensures that the new storage array will work seamlessly with the existing infrastructure.
