For the last several years, we have all witnessed the changes flash memory technology has brought forth. Compared to the hard disk, flash memory has faster access time and consumes very little power. The only drawback is it limited endurance and relatively slow write speed due to bulk erase requirement. Next on the horizon is the Phase Change Memory.
Although it is not yet mass produced, it would be available in a very near future. Since it is byte addressable and does not have be erased before it can be updated, it would be totally different from flash memory when it is used as storage device. It would be faster, and the performance is predictable.

The operating systems like Linux was designed around the hard disk as the backing store and the whole I/O stack is optimized according to the hard disk characteristics.

I will present the issues that have to be dealt with to efficiently utilize the PCM based storage device.
