The part of memory is backed-up by battery and protected by the short power interruption and/or system crash. <> In the event of short power interruption, the memory controller goes into the self refresh mode, so that it keeps data. The rebooting system checks if the data is held in the NVRAM area and use it at recovery phase. <> The battery lasts only a few hours. The SPEC requires 72hour data protection. Our system is equipped with UPS. The UPS can enough energy to keep the controller and the first disk enclosure operational for a couple of minutes. The UPS detects power failure and singnal the system with SNMP protocol. <> Once the system detects power failure, it goes into the special mode which is similar to the panic dump. Like panic dump, it stops any further I/O service and dump the NVRAM area into the special partition in the OS disk. <> The OS disk is mirrored and guaranteed the power. Max 2GB NVRAM is saved sequentally within a limited time. <> At the next reboot with power coming back, the system checks if the data is saved in the special area and runs the special restoring program automatically. The program loads the special OS disk partition and restores the NVRAM area, before starting the usual OS. The usual OS sees the same NVRAM area as the system crash. =============================================================================== Generated on Tue Jul 8 23:47:11 EDT 2003 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2002 Standard Performance Evaluation Corporation
