How to Create Datastore using ISCSI LUNS on VMware?

Once you have configured the ISCSI storage on VMware ESXi, you can start creating  new datastore using those ISCSI LUNS. By default ,the wizard will try to create filesystem type as VMFS5  and this filesystem can be able to support up to 2TB LUNS. If you want that datastore to be accessed across VMware ESX/ESXi version 5.0 and lower , then you need to choose VMFS3 filesystem. You can also have an option to create NFS datastore which will be used to store ISO images and virtual machines snapshots.

Here we will see how we can create a new ESXi datastore using the ISCSI LUNS.

1. Login to vSphere Web-client .(Open a browser and enter the vCenter IP address)

    Hi Lingeswaran,

    Thanks for your article series on VMware. It will be great if you can share your lab set up configurations with me.

    Actually I am planning to create VM lab for practice to do that I am planning to buy new Desktop. I just want to confirm that which configuration could be suitable for that.

    Thanks in Advance.
