As I know new version of vSAN with the name of ESA has released :
1- Does it mean on vSphere8 when we want to run vSAN we have 2 options ? 1- vSAN ESA and vSAN OSA ?
2- Are the main difference between ESA and OSA : on ESA we don't use cache tier
3- As I find out we cannot run vSAN ESA for example on 4 DL580 G10 that I have in my site althought we can just run it on ready nodes such as VXRail . Is that correct ?
