Atos Origin: Optimizing Server Virtualization Costs
Intel® Xeon® processor 5600 series increases performance and lowers total cost of ownership of virtual environment
Atos Origin is a leading international information technology (IT) services company, providing hi-tech transactional services, consulting, systems integration and managed operations to deliver business outcomes globally. The company’s annual revenues are EUR 5.1 billion and it employs 49,000 people. Atos Origin is the Worldwide Information Technology Partner for the Olympic Games and has a client base of international companies across all sectors.
Atos Origin manages core IT infrastructures for its clients. To help maximize use of data center space, and to reduce power consumption and associated costs, Atos Origin virtualizes as much of its customers' IT workloads as possible by default. It runs, on average, sixteen virtual machines(VM) per physical server powered by Intel® Xeon® processor 5500 series with eight cores (dual-socket servers running two VMs per core). To further increase its consolidation ratio, Atos Origin wanted to evaluate the advanced performance, energy efficiency and virtualization capabilities of the Intel® Xeon® processor 5600 series with six cores.
Using Intel’s Consolidate benchmark and a VMware ESXi* server, Atos Origin compared the performance of the Intel® Xeon® processor 5600 series to the previous-generation Intel® Xeon® processor 5500 series. It found, on average, a 30 per cent performance increase when running both Web and database workloads, and a 20 percent increase for email. In addition, average power consumption was 20 percent lower under load and 30 percent more efficient when idle thanks primarily to Intel® Intelligent Power Technology. The evaluation showed that the Intel® Xeon® processor5600 series had the potential to increase the current consolidation ratio by up to three virtual machines per core.
Thanks to its superior performance, processor memory and I/O subsystem design, the Intel® Xeon® processor 5600 series allows Atos Origin to further optimize the cost per virtual workload in its data centers. Greater energy efficiency through automated controls and more processor cores results in a 30-40 percent improvement in performance per watt, helping to lower running costs. Built-in Intel® Virtualization Technology² (Intel® VT) improves performance, enabling Atos Origin to extend virtualization to more processor- and I/O-hungry applications. Virtualizing more of the server environment simplifies management and extends the benefits of virtualization to the majority of workloads. Combined, these benefits simply help Atos Origin do more with less to lower the per VM cost to the client in both monetary and environmental terms.
