The computing industry has made tremendous progress in developing very fast storage solutions – high speed disk drives, storage area networks, efficient file systems – all to deliver the information as fast as possible. Many of these solutions are very sophisticated and smart – disk drives could be striped together to improve performance, equipped with a front-end cache which will store frequently used pieces of data, modern file systems can optimize the block layout to factor in disk rotation latency and predict which blocks would be needed so there will be very little delays. However, many of these advanced solutions were implemented for the physical world where programs and data were mostly isolated from each other and optimization didn’t take into account any workload interference.
