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.
