Item FRU 1-Wire EEPROM SPD Purpose? (e.g. boot code) Card manufacturing information Holds default controller properties/settings Memory configuration data How is data input to this memory? Programmed at ICT during production. ROC writes data to this memory Pre-programmed before assembly SBR SPI Flash Flash ONFI Backup Flash SDRAM H310, H310M PERCs NVSRAM FRU 1-Wire EEPROM SBR Bootloader FPGA configuration data Card firmware Holds cache data during power loss Cache for HDD I/O Pre-programmed before assembly Pre-programmed before assembly. Can be updated using Dell/LSI tools Pre-programmed before assembly. Can be updated using Dell/LSI tools FPGA backs up DDR data to this device in case of a power failure ROC writes to this memory - using it as cache for data IO to HDDs Configuration data Card manufacturing information Holds default controller properties/settings Bootloader ROC writes configuration data to NVSRAM Programmed at ICT during production ROC writes data to this memory Pre-programmed before assembly Flash Card firmware PCIe SSD Extension Card Switch Configuration EEPROM Configuration for PLX PCIe switch, setting registers IDSDM SPI Flash MCU Exclusively used by the controller Firmware Pre-programmed before assembly. Can be updated using Dell/LSI tools The EEPROM image is pre-loaded at factory before assembly. Once assembled on the card, data can be entered via PLX Device Editor or PLX EEP DOS based tool.
