- VMware has implemented telemetry to paint a clearer picture
- Turns out vSAN storage and HCI clusters were over-specced
- This change could result in huge cost savings
VMware has admitted overly conservative guidance based on synthetic testing caused the company to over-spec its storage servers for years.
New telemetry data shows real-world vSAN ESA clusters actually use significantly less RAM and CPU than the company had previously thought, allowing the company to lower hardware requirements for its vSAN storage clusters and vSAN HCI clusters.
By building to lesser specifications, VMware is now able to make servers cheaper, more energy efficient, and even more compact.
VMware overengineered storage servers for years
Old synthetic testing was not reflecting of real-world behavior, so when VMware implemented telemetry across thousands of production clusters, it found that vSAN uses much less RAM than anticipated, and generally fewer CPU resources too.
“We are thrilled…
