IT TODAY Run the NUMBERS Economics and performance make Linux on System z the clear choice D ata centers run a range of business workloads, including batch and transaction processing, business applications, complex data analysis, collaboration and social business. It’s easy to gravitate toward one particular server as being good for all of these workloads; however, they all have different requirements. For that reason, IBM offers different types of servers. John Shedletsky is vice president of IBM System z Competitive Technology. Emily Farmer is a senior research consultant in the IBM Software Group Competitive Project Office. It’s essential to understand what hardware is best suited for which applications and why. Determining the best placement of business workloads should focus on the platform that delivers the best performance at the best cost with the best quality—a concept known as “best fit.” Consider these three workload classes and see why the best fit is on IBM System z*: 10 // JULY/AUGUST 2013 1Linux Consolidations Several characteristics make the mainframe a highly efficient platform, especially for consolidating Linux* workloads. Its core features—processing power, large cache and a dedicated I/O subsystem—provide superior scalability and throughput. In addition, exceptional workload management, when com- bined with the aforementioned capabilities, makes the mainframe especially good for consolidating Linux workloads. Workload management refers to the effectiveness and efficiency of the virtualization layer to manage resources across multiple workloads. To realize the best cost per workload, a platform must maximize CPU utilization and
