I was born in a cross-fire hurricane
And I howled at my ma in the driving rain,
But it’s all right now, in fact, it’s a gas!
But it’s all right. I’m Jumpin’ Jack Flash,
It’s a Gas! Gas! Gas!
Those familiar with Moore’s Law have seen the disparity between disk and CPU performance increase. Today’s CPUs can easily out-process the data provided to them by even the fastest disk. Why is that?
There is a physical limitation on the rate at which we can spin platters. Our ability to engineer mechanical devices to spin highly unstable platters close to moving heads which are microns away from the surface are limited. Material science, stresses, quality of the bearings – all require tolerances that are approaching our physical limitations. Yet, we seem to be always finding new approaches to managing silicon fabrication.
The end of the mechanical age is near.
Enter flash. Freeing us from our mechanical limitations, flash enables the development of ‘silicon drives’ with speeds approaching those of their silicon CPU partners. With prices declining, these drives are fast becoming more affordable. Yet with still a significant price disparity to their slower, yet higher capacity mechanical cousins, what is the alternative?
Hybrid storage. Take the performance advantage of silicon flash, with the mechanical capacity of drives. Balance these devices for the workload, and you get unmatched price-performance. There is a whole class of devices emerging that support this philosophy. The question is, do systems engineers have the tools to understand their applications sufficiently to tune configurations to optimize this opportunity.
It’s nascent. More education than marketing is required.
Tell me it isn’t so… I’m listening.
