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.
Each filesystem was composed of two RAID-groups; each RAID-group was composed of 17 data disks and 1 parity disk. Four spare disks were present.
The F1 filesystem was striped across both primary disk controllers on the first node. The F2 filesystem was striped across both primary disk controllers on the second node.
Replaced "." with ".__" in svc.c line 399 of benchmark source, for portability.
Server tunings:
options nosnap 1 -- disable periodic Snapshot creation, for reproducibility
options autosupport.enable 0 -- disable autosupport e-mails, for SUT isolation
options raid.scrub.enable 0 -- disable periodic RAID scrubs, for reproducibility
options minra 1 -- minimize file read-ahead
The tested system was a failover cluster comprised of two nodes joined by a cluster interconnect.
Each node was the owner of one filesystem, but the disks were dual-attached so that, in the event of a fault, they could be controlled by the other node using a secondary loop.
Each RAID-group was on a distinct pair of FCAL loops: one primary and one secondary.
The cluster option was licensed an enabled.
