Somewhat off topic, but how are you generating 10,000 IOPS by carving a 16TB LUN/volume from 12 x 2TB SATA disk spindles? Such drives aren't even capable of 200 seeks per second. Even if they were you'd top out at less than 2,500 IOPS (random). 16TB/12=1.33 TB per disk. No such capacity disk exists. So I assume you're using 12 x 2TB disks and slicing/dicing out 16TB. What am I missing Dave? -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
