Oracle R Enterprise Performance on Intel® DC P3700 Series SSDs

Solid-state drives (SSDs) are becoming increasingly popular in enterprise storage systems, providing large caches, permanent storage and low latency. A recent study aimed to characterize the performance of Oracle R Enterprise workloads on the Intel® P3700 SSD versus hard disk drives (HDDs), with IO-WAIT as the key metric of interest. The study showed that Intel® DC P3700 Series SSDs reduced I/O latency for Oracle R Enterprise workloads, most notably when saving objects to Oracle R Enterprise datastore and materializing scoring results.

The test environment was a 2-node Red Hat Linux 6.5 cluster, each node containing a 2TB
Intel® DC P3700 Series SSD with attached 2 TB HDD. As the primary objective was to identify applications that could benefit from SSDs as-is, test results showed the performance gain without systems modification or tuning. The tests for the study consisted of a set of single analytic workloads composed of I/O, computational, and memory intensive tests. The tests were run both serially and in parallel up to 100 jobs, which are a good representation of typical workloads for Oracle R Enterprise customers.  

The figures below show execution time results for datastore save and load, and materializing model scoring results to a database table. The datastore performance is notably improved for the larger test sets (100 million and 1 billion rows). 
For these workloads, execution time was reduced by an average of 46% with a maximum of 67% compared to the HDD attached to the same cluster.

The entire set of test results shows that
Intel® DC P3700 Series SSDs provides an average reduction of 30% with a maximum of 67% in execution time for I/O heavy Oracle R Enterprise workloads. These results could potentially be improved by working with hardware engineers to tune the host kernel and other settings to optimize SSD performance. Intel® DC P3700 Series SSDs can increase storage I/O by reducing latency and increasing throughput, and it is recommended to explore system tuning options with your engineering team to achieve the best result.
