The meta-data management also has implications on performance. High-frequency trading As noted above, high-frequency trading HFT is a form of algorithmic trading characterized by high turnover and high order-to-trade ratios.
The success of computerized strategies is largely driven by their ability to simultaneously process volumes of information, something ordinary human traders cannot do.

The host only knows about the logical disk the mapped LUN and so any changes to the meta-data mapping is transparent to the host.
