With the much anticipated launch of 12gb/s SAS MegaRAID and 12Gb/s SAS expanders featuring DataBolt™ SAS bandwidth-aggregation technologies, LSI is taking the bold step of moving beyond traditional IO performance benchmarks like IOMeter to benchmarks that simulate real-world workloads.

In order to fully illustrate the actual benefit many IT administrators can realize using 12Gb/s SAS MegaRAID products on their new server platforms, LSI is demonstrating application benchmarks on top of actual enterprise applications at AIS.

For our end-to-end 12Gb/s SAS MegaRAID demonstration, we chose Benchmark Factory® for Databases running on a MySQL Database. Benchmark Factor, a database performance testing tool that allows you to conduct database workload replay, industry-standard benchmark testing and scalability testing, uses real database application workloads such as TPC-C, TPC-E and TPC-H. We chose the TPC-H benchmark, a decision-support benchmark, because of its large streaming query profile. TPC-H shows the performance of decision support systems – which examine large volumes of data to simplify the analysis of information for business decisions – making it an excellent benchmark to showcase 12Gb/s SAS MegaRAID technology and its ability to maximize the bandwidth of PCIe 3.0 platforms, compared to 6Gb/s SAS.

LSI MegaRAID SAS 9361-8i storage performance on display using Spotlight® on MySQL, which is monitoring the data traffic across Intel’s new R2216GZ4GC server based on the new Intel® Xeon® processor E5-2600 v2.

The demo uses the latest Intel R2216GZ4GC servers based on the new Intel® Xeon® processor E5-2600 v2 product family to illustrate how 12Gb/s SAS MegaRAID solutions are needed to take advantage of the bandwidth capabilities of PCIe® 3.0 bus technology.

When the benchmarks are run side-by-side on the two platforms, you can quickly see how much faster data transfer rates are executed, and how much more efficiently the Intel servers handles data traffic. We used Quest Software’s Spotlight® on MySQL tool to monitor and measure data traffic from end storage devices to the clients running the database queries. More importantly, the test also illustrates how many more user queries the 12Gb/s SAS-based system can handle before complete resource saturation – 60 percent more than 6Gb/s SAS in this demonstration.

What does this mean to IT administrators? Clearly, resourse utilization is much higher,  improving total cost of ownership (TCO) with their database server. Or, conversley, 12Gb/s SAS can reduce cost per IO since fewer drives can be used with the server to deliver the same performance as the previous 6Gb/s SAS generation of storage infrastructure.
