re: Flash Dependent Storage Systems Take Off In 2012
I think we agree with each other. I am not saying that Flash will never replace disk. It will definitely, without a doubt replace disk as the price continues to come down and capacities increase. The technology is across the board superior to disk. I am just not sure that 2012 will be the year (as the title states) when Flash dependent systems take off and start replacing disk arrays in substantial numbers. It is like tape vs. disk. Disk is way better than tape all around and has largely replaced tape for everything other than archiving and back-up, but it didn't happen overnight. I think you will see Flash integrated with disk systems, which already exists, and then as the Flash technology matures people will ditch disk altogether.

BI will be the first to go all Flash as the software already supports it and the data volumes (a couple of hundred GB) are relatively small. For the 10s of TB RDB workloads and hundreds or even PB unstructured workloads, it will probably take a few years at least.

SimonS1 - thanks for reading and for the response. I agree that Flash only systems have their work gut out for them to get pricing to the levels. But to a large extent we are there when comparing flash only systems to 15k mechanical drive systems. Also for the business that would like their "ERP, e-mail, BI, etc..." to run faster they can use systems that integrate flash. We discuss this concept in our recent article "Integrating PCIe SSD Into The Storage System"

Not sure about this one. There is a demand for Flash based storage systems, but the workloads which need Flash response time are pretty rare. People would like their ERP, e-mail, BI, etc systems to run faster, but they don't really care enough to justify the additional costs. It will take a ramp up in production and a drop in price before all-SSD storage systems become mainstream. The use of Flash for hot-objects is becoming pretty common.

If you thought consumerization killed UC, think again: 70% of our 488 respondents have or plan to put systems in place. Of those, 34% will roll UC out to 76% or more of their user base. And there’s some good news for UCaaS providers.
