What will $0.08 get you with storage? Typically, not much. But, on $0.08 will change the way you think about storage and cause you to question everything storage vendors have told you. Find out more in this presentation
IO has long been a serial function designed for single processor machines. While processor speeds climbed, IO processing benefitted from it and kept pace with computational gains. However, when power and heat concerns flattened the CPU clock speed ramp, chipmakers switched their focus on more cores per socket. Now, multi-core designs have the potential to do far more compute work across separate virtual machines than the serial IO is able to process on a single CPU. In other words, serial IO limits the potential work that multi-core CPUs can accomplish. And that IO gap is widening. The physical machine can’t get enough input and output to keep all those processors busy computing – so CPUs go idle and we are forced to spread the work over more underutilized servers.

Even the most modest server-class machines come equipped with multi-core CPUs. Take Lenovo’s ThinkServer RD530 with 10 CPU Cores for under $2,000.
Instead of having just one CPU working for you, the system effectively has 10 workers that can be used simultaneously. Several applications can run concurrently with CPUs individually dedicated to them.
