The authors of this white paper had the privilege to be among the first to see Easy Tier "In action" while preparing the information presented here. In one key test, documented in a subsequent section of the paper, the author placed 34 terabytes of SPC-1 data onto 96 SATA drives. The author then started the SPC-1 test workload, while also enabling Easy Tier. During the ensuing 24 hours, the author watched the performance of the system gradually improve, until finally the system throughput achieved a level more than 3 times its initial value. No other action was needed on the part, other than to observe a significant I/O throughput increase with a complementary reduction in response time.
