VSAN Storage Scalability
If I understand VSAN is the technology that enables the sharing of each ESX host Disk to make a large shared disk.
For instance if you have ESX1 and ESX2 with 40 GB disk each, then you can create one large Shared disk of 80 GBs combining ESX1 and ESX2 disks.
Now I would like to know how scalable it is, in case we need a large amount of storage
.For instance, dedicated storage such as EMC, they provide Racks of storage that can hold pitabytes of data.
So is VSAN used in environment where they do not have to much data to store and sometimes they will have to offload the old data off the VSAN to an external storage device?
Any Expert to elaborate in that point?
