Sometimes a local hard drive(s) is all you need. But often the right solution is something else. Look here for info. related to alternatives, some of which are successfully used in production and very cost-effective.

This is right one. Sorry for the confusing.

Re-test head node to local 4T drive:

The previous results for NAS-iscsi setting. Here is the result from compute nodes (or from head node) to NAS-nfs:

write speed 104 M/sec
rewrite speed 51 M/sec
read speed 107M/sec

I use this command to do the test:

bonnie++ -n 0 -u 0 -r `free -m | grep 'Mem:' | awk '{print $2}'` -s $(echo "scale=0;`free -m | grep 'Mem:' | awk '{print $2}'`*2" | bc -l) -f -b -d /users
