Other Notes

The system under test was a single SpinServer 4100 with five 16-disk SpinStor 200 Arrays (2 Raid + 3 JBOD)
Both FC ports of the SpinServer 4100 were connected to the disk subsystem for performance and availability.
One RAID array had a single JBOD expansion array. One RAID array had two JBOD expansion arrays.
The two RAID arrays were chained together with redundant FC loops.
The single filesystem, F1, was comprised of 15 RAID-5 sets. Five additional disks were configured as hot spares.
Each RAID set had a strip size of 32 KB.
Server Tunings:
All network ports were set to use jumbo frames (MTU=9000).
All scheduled SpinShot jobs were disabled for reproducibility
Each SpinStor 200 RAID Array utilized dual RAID Controllers, each with 256 MB of battery-backed RAM.
The RAID Controller was configured with a Write-Back cache that switches to Write-Through mode when
the charge level of its battery is below 72 hours.
The SpinServer 4100 has 1.7 Gbytes of UPS backed cache that will survive a power failure or an operating
system crash. In the event of a power failure or low battery condition, the cache is written to
mirrored local SCSI disks. Recovery software restores the cache when power returns. This RAM is not used
by the operating system as general purpose memory but as NVRAM that is dedicated for caching disk reads
and writes. The UPS is guaranteed to have sufficient energy after a battery low condition to
flush the entire contents of the 1.7 GBytes of cache to local drives.
