Nanotechnology (sometimes shortened to “nanotech”) is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres. Quantum mechanical effects are important at this quantum-realm scale.
Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.
Microfabrication is the term that describes processes of fabrication of miniature structures, of micrometre sizes and smaller. Historically the earliest microfabrication processes were used for integrated circuit fabrication, also known as “semiconductor manufacturing” or “semiconductor device fabrication”. In the last two decades microelectromechanical systems (MEMS), microsystems (European usage), micromachines (Japanese terminology) and their subfields, microfludics/lab-on-a-chip, optical MEMS (also called MOEMS), RF MEMS, PowerMEMS, BioMEMS and their extension into nanoscale (for example NEMS, for nano electro mechanical systems) have re-used, adapted or extended microfabrication methods. Flat-panel displays and solar cells are also using similar techniques.
We’re seeing workloads that are much more IOPS based than we previously thought, but at the same time we need lots of capacity. The key point is that we really need only high IOPS performance when an application is running. Consequently, we can make a portion of the storage a fairly small SSD-based system that has tremendous IOPS capability but a fairly small capacity at a reasonable price point. Then, we also create a very large but lower performance storage pool using the huge capacity and great price point offered by 7.2K drives. As a result, I think we’ll see 15K drives disappearing from the market during the next few years.
The key to being successful is to marry the two storage pools with middleware that enables the data to be easily moved between the two. Tiering software is probably the best solution, but the current state of tiering is pretty bad. What is needed is tiering software that quickly determines when data must be moved from slower storage to really fast storage and back again. This has to happen in a way that the application performance does not suffer too much because of the data movement.
New technologies will provide direct interfaces where you do not need a bridge anymore for the processor, the memory, cpu and storage becomes one, most important is the direction of storage technologies that will provide a roadmap for the future, the miniturisation of the computer where a mobilephone or tablet has the processing power of a mainframe with hundreds of terabytes of data, where voice activate and response will form close to 90% of the devices built, where wireless technologies will link and present data in so many ways, you can communicate with your TV, ATM, control your home, where the computer will totally “disappear” but appear in other smart devices. All you need to do to control devices is by training your eyes, gesturing or voice. Everything will be auto-piloted with an option for manual overide. Aircraft, cars and ships will be piloted this way, everything around the house, office will be too. SmartGrids will power everything wirelessly intergrated with GPS where every space will be defined. Everything can linked to the matrix internet where billions and billions of devices are interconnected. Intelligence will be built into softwares with greatest capabilities never seen. A world where humans are pampared with technology.
