WikitipSeparate storage from blade processorsWhen deploying blade servers, use virtualization to separate storage from processors and ensure there is no fixed association of an application with a physical server. By using virtualization engines on the market today, system software can be centralized and version control can be managed. This means OS failures can recover from a central repository of OS versions enabling super-fast OS problem resolution by, for example, reverting to a previous version of an OS. By virtualizing the storage, data can be striped across multiple arrays so that no single disk failure will cause applications to crash. By separating storage from server, all recovery files such as journals which preserve the state of an application can be accessed by other servers, which minimizes the time to recover. Configure blades with storage external to the servers and ensure the servers have no fixed association with applications. Focus blade virtualization projects on creating simple robust environments that can withstand the failure of commodity components, and don’t worry so much about saving processor cycles. |
Featured Case Study
Financial giant goes greenThe corporate IT group of a very large, worldwide financial organization with 100,000 employees, has initiated an ongoing “greening” process. This is focused largely on reducing energy use both to decrease the corporation's carbon footprint while creating a net savings in operational costs over the lifetime of new, more energy-efficient equipment, including new storage systems. |

Featured How-To Note |
Planning a Green Storage InitiativeFluctuating energy prices have heightened electricity and energy consumption as a major issue within the technology community. IT is a significant consumer of energy and IT energy costs have been rising disproportionately because of continued investment in denser IT equipment. Estimates from the EPA and others indicate that IT will account for 3% of energy consumption by 2012. | |||
