Thus, not only does the hardware platform need to support such an approach but the individual SAP Technology Stack layers and components that sit atop the hardware stack must support dynamic reallocation as well. These types of solutions are labeled "hardware partitioning" and are typically predicated on less than commodity hardware platforms. • Software partitioning is becoming more popular, too, as companies like Microsoft and VMware (recently swallowed up by EMC) promote virtualization software that allows a single physical server and its resources to be chopped up virtually into multiple servers, each capable of hosting applications in a "guest" OS instance.
The bottleneck in a system never disappears; it only finds a new home. It might come to rest anywhere within the technology stack, in fact database layout/configuration issues or SAP application or profile misconfiguration are other examples. The good news is that every time a particular bottleneck is eliminated, even though a new bottleneck rears its head, overall throughput and/or response time of the system only continues to improve! Eventually, you'll find yourself arriving at one of two conclusions I've arrived at myself time and again, either that my system's overall performance is well within SLAs or my budget simply can't take the expense of finding and relocating any more bottlenecks!
Goals may be uncovered, therefore, that are simply not achievable 39 40 with the available budget, talent, and so on this is an important benefit of the mapping process itself, feeding the iterative solution vision process along the way. 3 Ranking Solution Characteristics The value an organization places on various system "descriptors" solution characteristics must be understood before it's possible to prioritize stress-testing goals and overall tuning success criteria. I often use something I call the "solution characteristics matrix" to help me understand how important certain characteristics are to an SAP IT group and the business organizations it services.
