For service, the Sun Flash Accelerator F80 PCIe Card contains updatable flash ROM for storing the BIOS and firmware, and also NVRAM for storing nonvolatile configuration data. Use DDCLI to monitor and service the card. You can also use the MegaRAID Storage Manager (MSM) software utility for troubleshooting.
In addition, you can monitor Sun Flash Accelerator F80 PCIe Card health and flash media life through card bracket LED status indicators. The card has three LEDs on the PCI bracket to indicate activity, drive life, and status. See Troubleshooting Using Card LEDs.
The Sun Flash Accelerator F80 PCIe Card requires no periodic maintenance. For data protection, the Sun Flash Accelerator F80 PCIe Card is designed with energy storage components, such as on-board capacitors, to complete buffered writes to the persistent flash storage in case of a sudden power loss. These energy storage components are designed for the life of the Sun Flash Accelerator F80 PCIe Card and do not require periodic maintenance.
The Sun Flash Accelerator F80 PCIe Card is a complete field-replaceable unit (FRU), with no removeable components. Individual flash disks are not field serviceable, and should never be removed, even though the ddcli utility identifies each SSD flash module DFF using unique descriptors.
