This is pretty bad. My last 14 SAS drives RAID-6 array achieved 500
MB/s write, 1GB/s read sustained. What is the SAS controller? the RAID
controller? Please provide more details about the
enclosure/drives/cabling too.
What is the kernel/distro? Did you striped your LVs across multiple
physical volumes except the last one? What's the output for pvdisplay,
vgdisplay, lvdisplay?
