It’s that time of year where you can feel like you’re being squeezed from every direction. Hypervisor costs don’t have to be apart of the equation however. Being on lots of sales calls, a common misconception is that if you want to add more storage to Nutanix to also have to pay for more hypervisor licensing. This is not true.
The Nutanix virtual storage controllers don’t relay on any hypervisor management features for the features to work. No vCenter, no SCVMM, and WebVirtMgr(KVM) is needed to run the Nuntanix Operating System(NOS). NOS upgrades are handled without interaction from the hypervisor. The Nutanix AutoPath features allows for seamless upgrades in a non-disruptive fashion.
With vSphere the hypervisor can be upgraded in a rolling fashion using the virtual storage controllers as the focus point. The virtual storage controllers maintain a list of the hypervisors forming the cluster so you can easily run esxcli commands to update the hosts.
Hyper-V can be ran with the core edition and running Linux VM’s don’t require licensing.
KVM no licences to worry about to my knowledge.(I am not strong in this area so Linux folks please chime in)
The 6020 from Nutanix offers 20% more storage than the 6050(for running server workloads), 30% less compute capacity and can be ordered with only 32 GB of RAM. Nutanix has background processes to move the cold data to the new nodes. Flash on the 6020 can be used by remote nodes if their local flash is full, the 6020 can help participate in replication to reduce hot spots in data protection. Spare compute can be used by vSphere vDR or Veeam Backup/DR products for recovery.
If your up on your orchestration you can also add automatically add the Nutanix nodes to your hypervsisopr management platform of choice based using the Nutanix REST-API.
Any other questions about Nutanix and\or maintaining an environment please leave a comment.
