The HPE Smart Array Gen10 naming convention follows a specific structure to identify controller capabilities:

• Class (P): The first letter indicates the class. P stands for Performance (others include E for Essential, S for Software). This matches "Class of Raid Controller."
• Series (4): The first digit represents the series generation or tier (e.g., 400 series vs. 800 series). This matches "Smart Array Series."
• SAS Lanes (16): The subsequent digits indicate the number of SAS lanes (e.g., 16 lanes). This matches "Number of SAS lanes."
• Port Type (ie): The letters following the numbers indicate port connectivity (i for Internal, e for External, ie for Mixed). This matches "Port Type."
• Form Factor (m): The suffix indicates the controller form factor (-m for Mezzanine, -a/-b/-c for Modular, -p for PCIe). This matches "Controller Type (form factor)."
