                                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.
<> The tested system was a failover cluster comprised of two nodes joined by a cluster interconnect.
<> The cluster option was licensed and enabled.
<> 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 via a secondary loop.
<> The F1 filesystem was built on the primary disk controller of the first node.  The F2 filesystem was built on the primary disk controller of the second node.
<> Each filesystem was composed of three RAID-4 groups; each RAID-group was composed of 8 data disks and 1 parity disk.  Two spare disks were present.
<> Server tunings:
<> options minra 1 -- minimize file read-ahead
<> date 0801 -- set clock to 8:01am for reproducibility
