In Nutanix nodes, there are SSD disks and SATA disks. Can we create two separate  datastores.  One datastore only contains SSD disks and one datastore only contains SATA disks

Hey @KCLO , so give me some time I will research on this configuration and get back to you soon.

In the meantime, you can create a new NFS datastore on physical hosts as mentioned in this article: https://portal.nutanix.com/page/documents/details?targetId=Command-Ref-AOS-v5_17%3Aacl-ncli-datastore-auto-r.html

Hey @KCLO , so I researched a bit and what I found was that on SAN LUNs you can do the above, but you cannot control this in Nutanix as we don't have external tiers for consumer use. All SSDs & HDDs creates one storage pool, that's out DFS(distributed Storage fabric-https://nutanixbible.com/). You can read more about it in the Nutanix Bible.

 

So for ESXi its one storage, we cannot separate at that layer.

But say I have EMC storage which has SSD & HDD, I can create a LUN from HDD and one LUN from SSD and present to ESXi, this way we have a SSD datastore and a HDD datastore.

I hope I was able to clear your doubt, let me know if you need help with anything else.:sweat_smile:
