vSAN 8 Total Cost of Operations (TCO)
VMware vSAN 8 can lower HCI TCO by up to 40% through a variety of new capabilities. In this paper, we seek 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…Read More

“The ramdisk “vsantraces” is full” error…
I’m here with another hot topic of VMware vSAN troubleshooting. Normally, if you installed your ESXi to a USB or SD device, the ramdisk for vSAN trace information may grow and fill the allotted ramdisk. We can redirect this logging to another location.
