Feature Summary
Intel® Storage Server SSR212MC2
12 Revision
1.2
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 port-
drive 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.
