VMware vSAN 8 can lower HCI TCO by up to 40% through a variety of new capabilities, and this is achieved in no small part by increasing usable storage capacity by up to 70%.These improvements are delivered through a new single tier architecture, RAID-6 Efficiency with RAID-1 performance, improved compression, and compute and performance optimization.

In this paper, VMware seeks to show how vSAN 8 with Express Storage Architecture can deliver lower storage TCO in several common deployment types, focusing primarily on capital cost differences between the previous generation of HCI – the original storage architecture, or OSA – and current generation. However, vSAN 8 can also deliver significant cost savings as compared to traditional external storage for both CAPEX and OPEX; we provide a high-level summary in this paper, but it is not the focus.
