In a stunning admission that has sent ripples through the data center world, VMware has confessed to over-specifying hardware requirements for its storage servers for years. The virtualization giant, now under Broadcom’s umbrella, revealed that its guidance for vSAN storage clusters was based on outdated synthetic testing, leading enterprises to purchase more powerful—and expensive—hardware than necessary.
