Executive summary

The Dell Compellent Flash-optimized array is a radically new storage platform that leverages flash in an innovative way. The Compellent flexible storage architecture acknowledges that not all flash is created equal thereby leveraging the unique strengths of different types of flash media appropriately. As a result, the Dell Compellent Flash-optimized array redefines the economics of high performance storage by delivering a truly high performing storage platform that is more cost effective than pure HDD systems. The solution discussed in this paper describes and demonstrates a reference architecture that delivers flash performance for Oracle OLTP workloads at the price of mechanical disk. The testing compares a Dell Compellent Flash-Optimized solution to a similarly priced solution consisting of 15k SAS HDD’s.

In this paper the benefits of the Compellent Flash-optimized array are presented by comparing its transactional performance under simulated (ORION based) and real world (TPC-C style) OLTP workloads to a similarly priced HDD based Compellent array.
