This is the finding of a TCO study conducted by Evaluator Group. In it we looked at two database environments, shown in graph directly below, generating 8 million transactions per minute, based on the TPC-C On-Line Transaction Processing (OLTP) benchmark. A cluster of servers with the Xeon Scalable CPU running vSAN on internal SSDs was found to be about one-third the cost of the same servers connected to an all-flash array (AFA). The graph at the bottom shows exactly where this cost differential comes from.
