First off, thank you everyone for developing this very cool and useful software. I was able to stand up a 3-Node 40TB test cluster on some old PE610s in only a few hours.
I've been researching storage options for the next version of our private cloud and been debating keeping the storage separated, either with dedicated arrays or a cluster like PetaSAN, or using one of the Hyperconverged options, such as vSAN or StarWind. Using StarWind as an example, their solution entails installing a virtual appliance on each vSphere host and attaching the raw local disks to the virtual appliance. The virtual appliances are then clustered and an iSCSI disk is presented to the hosts.
It seems to me that PetaSAN could be setup in exactly the same way. Is this practical? Would it be too much CPU/RAM overhead on the VM host to be worthwhile? Is there any benefit, besides server density? Has anyone tried this?
Your input is appreciated.
Thanks

If you will go with this, make sure you give required resources to the vms ( including 4G RAM per OSD ), Do not place several virtual OSDs on the same physical disk, make sure your hypervisor can give full io queue / threads to the vms and not limit them.
