- Login to your QNAP NAS and click iSCSI & Fibre Channel
- When first time started you will be asked if you wish to go through a configuration wizard. Click Next.
- We will start with the iSCSI Target creation.
- You can enter name and alias for your iSCSI Target.
- In next section we can enter username and password. Only letters and numbers are allowed. Let’s try to configure it with username and password.
- In the last section we have a summary of the items we configured. Important is to select Create a LUN and map it to this target.
- Now we are in the Block-Based LUN Creation Wizard section. Choose appropriate Storage Pool and the type of LUN allocation — thick or thin.
- We need to provide a LUN name and enter the desired LUN size. As I have cache disks I will use them.
- On the summary we can see all the configured settings.
- Our QNAP NAS iSCSI target is ready to be used.
VMware ESXi can use iSCSI either using Static or Dynamic discovery. I’ve tested it with both and I will descibre the process just with Dynamic.
- Login to vSphere.
- Navigate to your ESXi Server Configure -> Storage Adapaters -> iSCSI Software Adapter or your hardware iSCSI adapter.
- Click Dynamic Discovery and then Add.
- Enter iSCSI Server FQDN or IP address.
- I used CHAP configuration on QNAP so I need to enter it in ESXi as well. Set Authentication Method to Use unidirectioal CHAP if required by target.
- We need to rescan adapter in order to reflect changes. CLick Rescan Adapter.
- iSCSI LUN is visible and can be used as VMware Datastore.
Create iSCSI based VMware Datastore
- Click on Actions and then select Storage -> New Datastore
- Choose VMFS
- Select our iSCSI backed Disk.
- Choose desired VMFS version.
- I will use whole datastore size and use default settings.
- On the summary page we can review our configured settings.
- Datastore is visible in GUI and can be used by our VMs.
