Pass-through Disks
Storage on pass-through disks provides the following:
■ Very fast performance.
■ A very simple storage path because the file system on the host is not involved.
■ Better alignment under SAN.
■ Lower CPU utilization.
■ Support for very large disks.
Zerto Virtual Replication cannot protect virtual machines with pass-through disks. Also, a Hyper-V host with a pass-through disk is ignored by the Zerto Virtual Manager.
