As promised in my last post, and after reviewing the OP-EX and CAP-EX saving provided by looking at a Virtual Protocol Interconnect (VPI) oriented data center, we need to look at how the business can benefit from using such unified systems.
As described in my first post, we will be using off-the-shelf market-known applications from companies which are known in the industry. This post will review work done with GigaSpaces, a leading application provider in the financial sector, using their XAP 6.6.0.
Benchmark Software/Middleware components:
- GigaSpaces XAP 6.6.0
- GigaSpaces API: Java openspaces
- Space operation measured: write
- Sun JVM 1.6
We wanted to focus on one of the most important factors for the financial sector: low-latency and comparing the different interconnects: 1GigE, VPI (10GigE), and VPI (40Gigb/s InfiniBand). The results were stunning for both the “Mellanox High-Performance Enterprise Team” and GigaSpaces (who provided us great help in getting this benchmark running and analyzing the results).
The VPI (both IB and 10GbE) is better than GigE by 25 % to 100 % (the more partitions, more users, and larger objects to be used the more benefit the VPI technology will provide). When comparing the interconnect options provided by VPI, IB would see better performance than 10GbE. Latency as presented with GigaSpaces is below 1 ms transaction latency including sync with backup with 4K objects, with large amounts of concurrent users hitting the system in a high update rate. As you know, I truly believe in seeing the results and therefore below you’ll find the graphs of the results from our testing (which instantly generated quite of an interest with people in the industry).
In my next blog post I will review a variety of applications which we’ve conducted tests on – stay tuned.
But before I say my goodbyes I’ve got good news and bad news… Where to start?
Well, I’ll start with the bad – my next blog post will be taking place only next year; the good ones are (at least for me) that I’ll be on vacation
Have a happy new-year…
