Hyper-Converged Infrastructure comparison (Nutanix vs EVO:Rail)

Posted on Updated on

2015 IT Trends: Convergence, Automation, and Integration.

The hyper-converged gaining momentum each of the last few years, there are more and more customers taking notice. During VMworld 2014 in August, VMware announced of hyper-convergence: the EVO: RAIL, the combination of virtualization software loaded onto four blade servers, sliding on a rail into a 2u space of a server rack. It represents compute, storage, and networking in a single modular unit.

Please read my other post for VMware EVO:RAIL and Nutanix.

VMware software included with an EVO:RAIL appliance:

  •  vSphere Enterprise Plus
  • vCenter Server
  • Virtual SAN
  • Log Insight
  • Support and Maintenance for 3 years





Some customers are implementing non VMware products to virtualize workloads,  the flexibility to support more than VMware is quickly becoming important. VMware EVO:RAIL only support VMware while Nutanix support KVM or Hyper-V over VMware.

Read my other post for VMware and Microsoft Hyper-V 2012R2 here.



This comparison is not cover performance, only comparing the availability and data services that the hyper-converged platforms offer.

Nutanix are using a Virtual Storage Appliance (VSA). There is a VSA on each node in the storage cluster and they act like scale out storage controllers. While VMware has taken the approach of building VSAN as a module in the vSphere kernel. Each approach has its benefits and draw backs. The VSA model will use more host resources to provide storage services. Using the VSA is allowing vendors to offer deduplication, compression, backup and replication among other services. While VMware’s integrated approach uses far less resources, it does lag in the data services it can offer currently.
