Hyper-V virtual Fibre Channel – Virtual machine direct storage array connectivity with HBA

June 15, 2015 Leave a comment

With windows 2012 and earlier OS , it can use virtual Fibre adapter feature to provide direct storage array connectivity from virtual machine

Benefits
  • Optimal Storage performance and full protocol access
  • Supports guest clustering
Requirements
  • Must use NPIV enabled HBA adapters and FC switches
  • Create Fibre channel SAN within hyper –v Virtual SAN manager
  • Use same virtual SAN configuration and naming convention on Hyper-V failover cluster environment

The below session describes how to configure a Hyper-V hosts to provision virtual machine with  virtual Fibre Channel adapter.

Platform : A servers with Hyper-V on Windows 2012 R2. Two Dual Port HBA Adapter is installed on this host.

Step 1 : Open Hyper-V manager – Virtual SAN manager- Create Virtual HBA ( VHBA1)  for first physical adapter as shown below:

VHba

Note: There are two Physical HBA is installed on host .So created Virtual HBA for first physical adapter. You can configure both HBA for redundancy

After Victual HBA is created , configure Virtual HBA controllers to the Virtual Server

From the virtual server settings – Add Hardware –Select Fibre channel Adapter

Assign the virtual Fibre adapter to the virtual server

VHba2

Then next step is do the zoning on Fibre switch and register the host on storage array.

Hyper-V guest failover cluster- Provisioning Shared Virtual Disk

This post describes how to create shared volume disk for virtual servers. Using shared disk feature easily can implement virtual server’s cluster known as guest cluster. Virtual hard disk allows to share same disk between multiple virtual machines and this ideal solution when host SQL 2012/2014 cluster in virtual servers.

Note: SQL 2012 and earlier version doesn’t support cluster shared volume (CSV) disks.

Virtualization Platform: Windows Server 2012 R2 Failover Cluster using Cluster Shared Volumes (CSV)

Step 1  :  Go to first guest Virtual machine from failover cluster manager.

Step 2: Add new VHDX virtual Hard Disk with desired size in the host CSV shared Disk

Example: C:\ClusterStorage\VolumeX, where C:\ represents the system drive, and X represents the desired CSV volume number.

Step 3: In the virtual machine settings, under SCSI Controller, expand the hard drive that you created in the previous procedure.

Click Advanced Features.

In the details pane, select the Enable virtual hard disk sharing check box.

Step 4: Go to the Second Guest virtual server and add the same VHDX files you created on the first Guest virtual server and share them also like in previous steps

Step 5: Login to first guest virtual server and then go to disk management

Step 6: Initialize the Bring the disk online, partition and format the drive with NTFS
