Intel SSR212MC2 Hardware Technical Product Specification - Page 20

Feature Summary Intel® Storage Server SSR212MC2 Optionally, the initialization string can point to an external EEPROM. This EEPROM is used to store initialization parameters that are card-specific, like the SAS Base address. Once read, the parameters from the EEPROM will replace those from Flash memory. Expander Port Configuration The PM8388 supports 24 ports. 12 of those ports are connected to disk drives with a fixed portdrive slot mapping. Four ports are used for host connection to a SAS HBA in the server sub system. Four other ports are reserved for expansion purpose and are routed to a dedicated SAS-4i connector on the expander card. The remaining four ports are not used and must be disabled.
