Summary and Conclusions

The pass-through option offers a useful alternative to VHD storage for Hyper-V

guest VMs. Benefits include higher storage I/O performance and larger storage

capacity that goes beyond the 2040Gb VHD limit.

Deploying pass-through disks with QLogic Fibre Channel adapters and NPIV port

virtualization enables workload I/O isolation consistent with storage best

practices, as well as the ability to manage storage I/O traffic QoS per NPIV port.

Storage I/O traffic QoS management ensures delivery of VM workload SLAs as

well as dynamically shaping traffic patterns based on application requirements.

For example, the user can increase bandwidth priority when a backup application

workload is generating I/O, typically at night, during periods of low transaction

application workload traffic.
