The Tetris Effect: Increasing the Efficiency of Virtualized Infrastructure
|
|||||||||||||||||
| Virtualization and consolidation have been widely embraced to reduce capital and operating costs. Initial deployments have generally delivered some savings, but most organizations are continually over-provisioning capacity to mitigate risk resulting in inefficiency and waste. The traditional approach for determining capacity requirements by analyzing total utilization is now insufficient. As in Tetris, the factors equally important to the size of the workload are the shape, orientation, and ultimately the placements. These factors in combination determine how to make best use of available capacity. Dealing with these placements and the "fragmentation" they inevitably produce is the new frontier in capacity management. By failing to strategically place workloads, organizations not only increase operational risk, but lose significant opportunities to maximize efficiency by increasing densities and designing infrastructure according to required service levels. Ultimately it is the placement of workloads combined with appropriate resource allocations that will determine how efficient and safe an organization’s infrastructure is. 55 Minutes WMV, 37MB |
