I am currently investigating the conversion of ~50 phsyiscal blades, each housing two VMware GSX VMs to ESX v4. All the VMs have just slight differences (being the MySQL database), the rest of the OS and application are the same. Does anyone know if VMware supports something like differential disks on ESXvSphere 4? With this, one could save some terabytes on the expensive SAN storage.
Thanks for your comments,
iPhun.
