iSCSI Connections Within the Guest OS
Hyper-V supports iSCSI connections initiated directly from within a guest
operating system to an iSCSI storage array. In this configuration, an iSCSI
software initiator within the guest OS is connected to an iSCSI storage array.
The iSCSI connection and any iSCSI LUNs that are provisioned directly to
the guest OS are not visible by the parent partition. The parent partition’s
involvement is in the management of the networking devices and therefore is
not the primary focus of this document. For more information, see "Direct
iSCSI Connectivity Within Guest OS" on page 34.
Storage Options for Virtual Machines (VMs) in
Hyper-V
NOTE: The figures in this section do not represent best practices and are only
meant to depict possible configurations available with Hyper-V.
There are three major categories that must be considered for each disk that
will be presented to a VM. The options within each of the categories have a
unique set of attributes that determine critical factors such as compatibility,
performance, and availability:
DISK TYPE — The type of disk the VM utilizes.
• Virtual hard disk (VHD)
• Passthrough disk
DISK LOCATION — The physical location where the disk will be housed.
• Internal storage
• External storage
• SMB/CIFS share
DISK INTERFACE — Based on the type of virtual controller the disk is attached
to, the disk will be presented to the VM as the desired disk interface.
