hv_storvsc
HYPER-V(4) BSD Kernel Interfaces Manual HYPER-V(4)NAME
hv_storvsc -- Hyper-V Storage Virtual Service Consumer
SYNOPSIS
To compile this driver into the kernel, place the following lines in the system kernel configuration file:
device hyperv
DESCRIPTION
The hv_storvsc driver implements the virtual store device for FreeBSD guest partitions running on Hyper-V. FreeBSD guest partitions running
on Hyper-V do not have direct access to storage devices attached to the Hyper-V server. Although a FreeBSD guest can access storage devices
using Hyper-V's full emulation mode, the performance in this mode tends to be unsatisfactory.
To counter the above issues, the hv_storvsc driver implements a storage Virtual Service Consumer (VSC) that relays storage requests from the
guest partition to the storage Virtual Service Provider (VSP) hosted in the root partition using the high performance data exchange infra-
structure provided by hv_vmbus(4) driver. The VSP in the root partition then forwards the storage related requests to the physical storage
device.
This driver functions by presenting a SCSI HBA interface to the Comman Access Method (CAM) layer. CAM control blocks (CCBs) are converted
into VSCSI protocol messages which are delivered to the root partition VSP over the Hyper-V VMBus.
SEE ALSO hv_ata_pci_disengage(4), hv_netvsc(4), hv_utils(4), hv_vmbus(4)HISTORY
Support for hv_storvsc first appeared in FreeBSD 10.0. The driver was developed through a joint effort between Citrix Incorporated, Micro-
soft Corporation, and Network Appliance Incorporated.

FreeBSD support for hv_storvsc was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.
