Other Notes

The system was equipped with one array controller and five disk enclosures.
The system was also equipped with a BACKUP NODE which mirrors the NVRAM of the system under test and writes back this mirrored NVRAM data to disk when the system under test's NVRAM has failed.
The array controller activated one FC loop.
The first disk enclosure contained two Operating System disks and two disks for the BACKUP NODE.
Each of the other four disk enclosures contained fourteen user disks and a spare disk.
The user disks of each disk enclosure formed a RAID 1+0 group, except for the first enclosure.
A filesystem was comprised of the four disk enclosures.
The TOE handles TCP. Jumbo Ethernet frames are not used.
The following NFS and filesystem options were used; maximum journal size, no quota, no atime, no subtreecheck, no root squash, no privileged port check.
1 GB of the 3 GB main memory is battery backed, called NVRAM, and contains all data that is pending change on the disks. Specifically, the other 2 GB of main memory can be lost in a reboot or power loss failure without loss of file system data.
Using the UPS, the contents of the NVRAM is saved into a reserved area of the OS disks within a limited time.
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.
In the event of short power interruption, the NVRAM memory controller goes into a self refresh mode, so that it preserves its data. The rebooting system checks if there is pending changes in the NVRAM area and completes this disk changes during a recovery phase.
The battery lasts only a few hours. The SPEC requires 72hour data protection. Our system is equipped with UPS. The UPS has enough energy to keep the controller and the first disk enclosure operational for 15 minutes. The UPS detects power failure and signal the system with the 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. The (maximum of 1GB) NVRAM is saved sequentially to the OS disk within 10 minutes during which the UPS is guaranteed to provide power.
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.
