Peter Vajgel put forth on 2/1/2011 1:20 PM: > At the scale we operate it does. We have multiple variables so the number of combinations is large. We have hit every single possible hardware and software problem and problem resolution can take months if it takes days to reproduce the problem. Hardware vendors (disk, controller, motherboard manufacturers) are much more responsive when you can reproduce a problem on the fly in seconds (especially in comparative benchmarking). The tests usually run only couple of minutes. With 12x3TB (possibly multiplied by a factor of X with our new platform) it would be unacceptable to wait for writes to finish. Hi Peter, When you mention scale, you're referring to the storage back end at facebook.com, your employer, correct? -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
