This test consists of Database and On-Line Transaction Processing (OLTP) workloads. OLTP is the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many enterprise deployments. These demanding 8k random workloads with a 66 percent read and 33 percent write distribution bring even the best solutions down to earth.


The clear linear-scaling picture continues in the OLTP test. The single ULLtraDIMM at 100% delivers 28,307 IOPS at 256 OIO, and averages 44,025 at 70%. With two ULLtraDIMMs at 100%, the average is 59,785 IOPS, and at 70%, they average 84,394 IOPS.






Two ULLtraDIMMs at 2ms nearly reach an astounding 80,000 IOPS.









The Web Server workload is read-only with a wide range of file sizes. Web servers are responsible for generating content users view over the Internet, much like the very page you are reading. The speed of the underlying storage system has a massive impact on the speed and responsiveness of the server hosting the website.


Two ULLtraDIMMs deliver an average of roughly 76,000 IOPS, and a single ULLtraDIMM delivers 37,000 IOPS.






The ULLtraDIMMs deliver excellent scaling in this test.
