Maximize IOPS and Storage Bandwidth for VM
+2
If we only have 2 VMs (1 CVM, another VM running heavy file uploading web application) per Nutanix KVM node, how can we fine tune / optimize storage bandwidth and IO for that web server?

The best way is to give the VM multiple disks. Also if possible increase queue depth of the apps so you have multiple drivers of storage. Single IO is slow in general so getting a multithreaded IO is key to driving a lot of IO.
Use LVM if needed to make a large drive out of multiple disks. This will give you the most performance, just like CPU and RAM, when you add disks you add more performance to the VM with Nutanix.

Is there any guideline how many vdisks should we add to a LVM?
