<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I wouldn’t expect much performance difference between NFS and Lustre if you are only using one OST and you only have one SATA drive on the back end. We did not find much performance improvement until we had all 64 nodes hammering Lustre. Our NFS server was constantly at a load of 8 or higher with one disk and with Lustre we had no load average with four OSTs and four drives. I would look at adding more OSTs and trying the test again, that is where Lustre really shines over NFS.<BR>

<BR>
The configuration I am using for Lustre is a system that has a second unused sata drive that I have partitioned into <BR>
1 MDS + MGS drive ( 4Gb )<BR>
1 OST Drive (76 Gb )<BR>
<BR>
I am sharing this out to the cluster on it’s own network interface that I have specified in the modprobe.conf file<BR>
<BR>
As the data we are manipulating ranges between 150Mb and 1.1Gb I have been timing who long it takes to read and write a 1.1gb file <BR>
<BR>
Basically<BR>
<BR>
Time dd if=/dev/zero of=<lustre fs>/file bs=16k count=65536<BR>
<BR>
And then <BR>
<BR>
Time dd if=<lustre_fs>/file of=/dev/zero<BR>
<BR>
Now to be honest I am not seeing any difference in Lustre compared with NFS<BR>
