Other Notes

There are three SGI InfiniteStorage IS220 RAID arrays included in
the SUT. Each IS220 contains 2 controllers. Each controller is
connected to an FC port. Also, each controller has a 1024MiB cache.
Cache is mirrored so that the total effective write cache per array
is 1024MiB. The total effective cache for three arrays is 3072MiB
There are 3 2000-SAS-EXP-146-Z expansion units connected to each IS220.
Each array base module and expansion module includes 12 physical disks.
A LUN is composed of 5 physical disks in a RAID-5 configuration.
Eight LUNs are configured on each IS220 array. Ownership ofthe LUNs
each array is evely divided between the RAID controllers in the array.
There is one test filesystem per LUN.
XFS is used for all test filesystems (F1-F24) as well as the OS.
2 quad port Gigabit Ethernet adapters were installed, one in each
full height PCIe slot. Only one quad port Gigabit Ethernet adapter
was used during the benchmark run.
Two dual port 4 Gb FC HBAs were installed in low profile PCIe slots.
One dual port 4 Gb FC HBAs was installed in a full height PCI-X slot.
The RAID arrays are cabled so that each controller in a given array
is serviced from a different HBA.
Ethernet frames (1500 byte MTU) were used during the benchmark run.
Server tuning to factory settings.
MiB = 2^^20 bytes and kiB = 2^^10 bytes in conformance to
standards laid out at http://physics.nist.gov/cuu/Units/binary.html
GB in Memory Size is 2^^30. Elsewhere, giga (G) is 10^^9.
