                                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 F1 filesystem was composed of one RAID-group, containing 20 data disks and one parity disk.
<> Server tunings:
<> options nosnap 1 -- disable periodic Snapshot creation, for reproducibility
<> options nosnapdir 1 -- skip .snapshot entry when reading directories
<> options raid.scrub.enable off -- disable periodic RAID scrubs, for reproducibility
<> options minra 1 -- minimize file read-ahead
<> options udp_lg_dgram.xmit_cksum.offload 1 -- offload checksum computations to NICs
