Other Notes

Failover is supported by an additional Celerra 514 Data Mover that operates in
standby mode. In the event of a Data Mover failure, this unit takes over the
function of the failed unit. The standby Data Mover does not contribute to
the performance of the system and is not included in the processor, memory,
or other components listed above.

ians cge1 packetburst=16 (maximum no. of packets to be processed at once)
Storage array notes:
The DMX1000-P used for storage exposes LUNs across multiple Fibre ports.
Each LUN is 11499MB in size and resides on a single disk. Four of the
fibre ports are connected to the Fibre switch and zoned along with the two
ports on the node. The filesystem is built on a stripe that spans across
the filesystem LUNs.
DMX1000-P was configured with 32GB memory. The memory is backed up with
sufficient battery power to safely destage all cached data onto the disk
in the event of a power failure.
