"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"The solution is quite expensive. That's one of the downsides to using it."
