Specifically, the other 512 MB of memory can be lost in a reboot or power loss failure without loss of file system data, because the card is interconnected to the other one. <> In the event of system crash, all data to be written back to disk is held in the portion of memory that is battery backed memory (NVRAM). This NVRAM protects pending data changes from loss during a short power interruption and/or system crash and reboot. <> All MTU size of the network ports were set to 1500. =============================================================================== Generated on Tue Aug 28 17:09:54 EDT 2007 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2007 Standard Performance Evaluation Corporation
