Dual 3.2Ghz xw8200 using 4Gb Nexsan SATABeast (RAID6 across 14 1TB drives, bonnie++ 1.01d, SLES 10)

This is an update to FilesystemBenchmarks. The same client host but with a 4Gb capable HBA and a 4Gb capable Nexsan SATABeast (last time we were bottlenecked by the 2Gb speed of the infrastructure).

You can change the read ahead blocks on Linux using blockdev --setra 16384 /dev/bigone/biglv. Here is the same benchmark with the 16K read ahead (note: jfs and xfs did not like the large read ahead).
