+ | This page is part of Q, the IT exam trainer. \\ See https://www.getshifting.com/q for more info \\ \\ **Question:** \\ What is the SR-IOV Number of virtual functions? \\ **Description:** \\ SR-IOV supports up to 43 virtual functions on supported Intel NICs and up to | ||
+ | 64 virtual functions on supported Emulex NICs. The actual number of virtual | ||
+ | functions available for passthrough depends on the number of interrupts vectors | ||
+ | required by each of them and on the hardware configuration of the host. Each | ||
+ | ESXi host has a limited number of interrupt vectors. When the host boots, devices | ||
+ | on the host such as storage controllers, physical network adapters, and USB | ||
+ | controllers consume a subset of the total number of vectors. Depending upon the | ||
+ | number of vectors these devices consume, the maximum number of potentially | ||
+ | supported VFs could be reduced. \\ \\ **Correct Answer:** \\ 1024 \\ {{tag>qq}} \\ |
