TCO Study: Dell EMC VxRail vs. DIY HCI Using vSAN ReadyNodes

TCO Study

This paper presents the results of a three-year total cost of ownership (TCO) study comparing Dell EMC™ VxRail™ appliances and an equivalent do-it-yourself (DIY) solution of standalone server hardware and software from the VMware vSAN ReadyNode™ (hardware compatibility list) configurations. For both options, we modeled total hardware capital expense, total software capital expense and operational expense for small, medium and large clusters over a three-year period. In fact, our TCO model shows VxRail configurations.

The overall TCO for the VxRail configurations is substantially lower than that for the DIY HCI configurations. This difference is primarily due to the bundling of VMware vSAN, Dell EMC RecoverPoint and Dell EMC CloudArray into VxRail, along with the lower operational costs inherent in VxRail packaged appliances, VxRail’s out-of-the-box experience, VxRail’s service solution and VxRail Manager’s orchestration capabilities.
Although the hardware costs for VxRail were higher than those for the DIY server configurations, the software costs and additional operational expenses for the DIY alternatives more than offset these costs.
If you are considering buying DIY server hardware for HCI, think again. Our TCO study projects that your total costs for an HCI solution will be much higher with a DIY solution than with an equivalent VxRail configuration over a three-year period.
