|LG #||LG Type||Network||Target File Systems||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.
