Hyper-V: Fibre channel support¶
https://blueprints.launchpad.net/nova/+spec/hyperv-fibre-channel
This blueprint proposes adding Fibre Channel support for the Hyper-V driver.
Problem description¶
At the moment, the Hyper-V driver supports attaching volumes only via iSCSI or SMB. In many cases, using FC based topologies might be desired.
Use Cases¶
This blueprint addresses deployers possessing FC based infrastructure.
This will enable attaching volumes exported by Cinder FC based backends using the retrieved target informations such as WWN and LUN.
Proposed change¶
A new volume driver will be introduced, having a workflow similar to the iSCSI volume driver. This means that the volumes will be attached to the instances as pass-through disks, making this transparent to the guest.
Alternatives¶
An alternative would be exposing virtual HBAs to guests. Although this has some benefits in terms of performance, it requires the guest to take part in the volume attach proccess.
Also, another limitation is that this scenario would be supported only in case of Windows Server guests.
