IOzone out where the buffalo roam …

or something like that. Running IOzone (slightly modified to be able to run in a region far outside cache) on JackRabbit-s. 8TB raw, using a 5.5TB partition of 13 drives in a RAID6. Run is done via

iozone -Ra -b /root/big.xls -n 64g -y 1g -g 1024g -q 1g

As soon as it finishes, I will put the excel file up for download. We are seeing pretty good performance. Here is a snippet:

The file sizes are 64 GB, 128 GB, 256 GB, 512 GB, and 1 TB (last row). As you can see its far outside cache, and performance is … quite good.
