                                Notes and Tuning

<> 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 one RAID-group; each RAID-group was composed of 26 data disks and 1 parity disk.  Twelve spare disks were present.
<> Each filesystem was striped across both disk controllers of a single 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 scalable cluster composed of twelve nodes joined by the BigIron switch
<> Each node was the exclusive owner of one filesystem.
<> Each group of eight clients was attached to a FastIron switch with an uplink to the BigIron.
