Reporting on a proof of concept exercise that involved running a customer's Oracle ERP on Oracle T-4 servers along with an Oracle RAC on T-4's, and storage was an Oracle ZFS Storage Appliance 7420 Darius Zanganeh reports that, even without any optimization, the Oracle system was 2.5x faster than the customer's IBM XIV production system in running their month end close. In running a number of so-called "ugly queries" the customer's system, which used 144 7200 RPM drives vs. 60 15k Drives for the Oracle equipment, ZFSSA demonstrated significant performance improvements in every case. Zanganeh suggests the reason is the size of available CACHE, which was 1TB of cache split on 2 controllers, 2 TB of L2arc Read SSDs and a few write SSDs. Furthermore, the Oracle configuration only used about 25% of what the total hardware setup could do.
