A 100 TeV proton collider represents the core aspect of the Future Circular Collider (FCC) study. An integral part of this project is the conceptual design of individual detector systems, which can be operated under luminosities reaching values of 3x10^35 cm-2s-1. One of the key limitations in the detector design arises from an increased number of pile-up events O(1000), which makes the particle tracking and identification of vertices extremely challenging. This talk will review the general ideas, which drive the current tracker/vertex detector design for the FCC-hh, like material budget, detector granularity, pattern recognition & tagging capabilities, uniformity of the magnetic field across the large detection region and occupancy/data rates. Extra focus will be also given on the limits of current tracker technologies and the requirements on their progress to meet the conditions of FCC-hh will be discussed.
