Other Notes

NetApp's embedded operating system processes NFS requests from the network layer without any NFS daemons, and uses non-volatile memory to improve performance.
The tested system was a failover cluster comprised of two nodes joined by a X1925A cluster interconnect.
The cluster option was licensed and enabled.
The memory size includes 3 GB in each node of the GF940c and 32 GB in the HDS 9980V.
Each disk controller had two FC connections and both were active.
Each node was the owner of one filesystem and each had the ability to take over the partner filesystem.
The F1 filesystem was striped across all loops of the first node. The F2 filesystem was striped across all loops of the second node.
In the event of a power outage, the UPS for the HDS 9980V has enough power to flush the entire cache to disk.
Server tunings:
date 0801 -- set clock to 8:01am for reproducibility
options minra 1 -- to minimize file read-ahead
options no_atime_on 1 -- to disable access time update
