as below, it is true that Flare will auto-manage for you. But determining the composition of the tiers beforehand does take some analytical work to make it most efficient.
We've got tools coming out this quarter that will allow you to take existing workloads and analyze them for FAST. To get access to these, you'll need to take advantage of PMAP, which is our access program for partners to get Unified performance data. That program is being realigned to make it more accessible - so stay tuned and contact EMC via your partner rep at emc. You will be required to take some courses and beyond that, pass an extensive test, but it's the same one our own people must take for the same level of access.
