Select Mount NFS read only if the volume is exported as read-only by the NFS server. The ESXi host uses these values to achieve multipathing to the NFS server mount point. With NFS 4.1, you can add multiple IP addresses or server names if the NFS server supports trunking. The system enforces a 42 character limit for the datastore name. After clicking Save, you can your NFS datastore mounted to all your ESXi hosts within a second or two.įor more detailed information about the terminology which I have used (SC, RF, etc) you can take a look Here.Important: If multiple hosts access the same datastore, you must use the same protocol on all hosts. For additional security or restriction you can use Filesystem whitelist and define the IP or IP range of the machines with access to the storage container. Compression also could be configured for inline or offline. 
With both of them turned on we were able to get 3:1 savings with full cloned virtual desktops (without compression). You can choose on which layer you want the deduplication to occur – SSD (online dedup) and HDD (offline dedup).
You can turn on Data Deduplication and Compression. You can also set an advertised capacity, which is how the capacity will be displayed in your vSphere console. You can reserve capacity for your datastore or you can leave it ‘0’, which means that it can grow until the physical free space is over. There is also possibilities to turn on ‘Erasure Coding’, but in my version of Nutanix OS (NOS) it is in Tech Preview, so we are not going to use it at this point. Here you have to choose if you want the datastore to me mounted automatically on all hosts or on specific hosts. Type a Name and select a Storage Pool. 
I have access to the Prism GUI for Nutanix cluster management. All disk are added in a single Storage Pool. The main purpose of the post is to describe how easy is to provision a brand new NFS datastore and attach it to your ESXi hosts. The datastore which was supposed to be used by us was created with Replication Factor 2 and we decided to create another one with RF=3, which provide higher level of data availability by keeping 3 copies of the data across the nodes. Recently we got access to a 16-node Nutanix cluster with vSphere on top of it.
