Pass-through Deployment
This scenario uses pass-through disks instead of VHD disks. A dedicated VHD LU is still required to host
virtual machine configuration files. Do not share this VHD LU with other child partitions on the Hyper-V host.
Figure 4 shows a scenario in which virtual machine configuration files, guest OS binaries, the page file and
SQL Server application libraries are placed on the VHD LU, and the application files are deployed as pass-
through disks.
Pass-through Connection
Figure 4.
Key considerations:
•
For higher throughput, deploy pass-through disks. Pass-through disks normally provide higher throughput
because only the guest partition file system is involved.
•
To achieve an easier migration path, deploy pass-through disks. Pass-through disks can provide an easier
migration path because the LUs used by a physical machine on a SAN can be moved easily to a Hyper-V
environment, and allow a new child partition access to the disk. This scenario is especially appropriate for
partially virtualized environments.
•
To support multi-terabyte LUs, deploy pass-through disks. Pass-through disks are not limited in size, so a
multi-terabyte LU is supported.
