SUSE Linux Enterprise Server running on HP blade servers was selected as the platform for its SAP ERP environment. The operating system combines high availability with low total cost of ownership, giving Mahindra Retail a solid foundation for its fast-growth business.
Many Mahindra Group companies use SAP software as their standard ERP system. The SAP at Mahindra was already running four different instances of SAP ERP 6.0 for Mahindra & Mahindra Ltd and other group companies. These were running on a variety of platforms: IBM* AIX* for the largest 2000+ user instance, and a mix of Linux* and Microsoft* Windows* for the other, smaller instances.
When the Mahindra Retail business was launched, the challenge was to find a platform for SAP that would offer high levels of performance and availability without correspondingly high initial and ongoing costs. The new business wanted to focus on capital and operational expenditures and on rapidly expanding from four stores to a planned 100 stores across India. Moreover, it did not want to divert investment to a costly proprietary UNIX* platform.
“We wanted to take advantage of the growing trend for enterprise-quality solutions on commodity hardware,” said Mr. Vijay Mahajan, Sr. GM IT Infrastructure, Corporate IT, Mahindra & Mahindra, Ltd. “Linux on x86 hardware was clearly a good way to minimise costs without sacrificing reliability.”
Following a detailed evaluation of possible platforms and discussions with Gartner Group, Corporate IT at Mahindra & Mahindra Ltd. selected SUSE Linux Enterprise Server as its platform for the new SAP environment. The company chose to deploy the operating system on a cluster of HP BL460 blade servers with quad-core Intel* Xeon* processors.
The SAP production environment for Mahindra Retail consists of two blades in an active/passive configuration for the Oracle* database and the SAP central instance, with a further two blades for the SAP applications.
“HP delivered the entire solution—both hardware and software—from a single point of contact, and they also provide a single support contract,” said Mr. Vijay Mahajan. “The high-availability clustering is an integral part of the SUSE Linux Enterprise platform, which meant that we were able to avoid the high cost of a proprietary piece of software.”
The SAP ERP environment is integrated using SAP NetWeaver* Process Integration (formerly SAP XI) middleware with Mahindra Retail’s Triversity Point of Sale (POS) solution, enabling the sharing of information on pricing, stock levels and promotions. About 100 employees in Mahindra Retail’s Bangalore headquarters are already using SAP, along with a couple of employees in each of the stores. The company anticipates the total number of users to be between 200 and 300.
“The feedback from users is excellent— they report perfect availability and low response time for SAP ERP running on SUSE Linux Enterprise Server,” said Mr. Prasad Patil, Manager IT, Corporate IT, Mahindra & Mahindra, Ltd. “Of course, the business is more interested in performance of the particular solution than the platform behind—the concern is much more whether that platform is delivering to the agreed service levels. In our experience, SUSE Linux Enterprise Server provides a robust, high-performance platform for SAP ERP, even on relatively low-cost Intel low-cost Intel processor-based hardware.”
Mahindra Retail’s SAP ERP environment is linked to a shared SAP NetWeaver BW system that runs consolidated financial reporting and business intelligence for the entire group.
With SUSE Linux Enterprise Server running on HP blade servers, Mahindra Retail has a low-cost, highly available platform for its SAP ERP environment. As the company embarks on its ambitious programme of new store openings, the solution has ample capacity to ensure continued excellent performance and availability.
“All of our platform decisions are driven by the underlying business requirements, in terms of balancing the cost of ownership against the required levels of performance, availability and security,” said Mr. Suhas Mhaskar, GM, Corporate IT, Mahindra & Mahindra, Ltd. “SUSE Linux Enterprise Server gives us a strong price/performance advantage over proprietary UNIX and Microsoft Windows as a platform for SAP ERP, and it offers enterprise levels of reliability and support.”
Mahindra Retail takes advantage of the high availability clustering solution in the SUSE Linux Enterprise platform for its platform for its business-critical SAP systems. SAP systems. In addition to minimising the support overhead, this helped keep acquisition costs low by removing the need to invest in a proprietary solution for high availability.
“SUSE Linux Enterprise Server has provided the availability we needed for Mahindra Retail within a single, cost-effective package,” said Mr. Vijay Mahajan. “The ability to do this on commodity hardware was a significant benefit, and we are now exploring the possibility of migrating our other larger SAP environments to the same platform.”
