I'm aware that VMware ESXi supports the creation of datastores on local Advanced Format 512e disks as of v.6.5. However, all the (very scarce) information I can find seems to suggest that virtual disks created on that datastore will still be exposed to the virtual machine as 512n disks.
For some workloads, performance could be seriously degraded if the guest OS believes the disk is natively 512 byte sectored, producing lots of read-modify-write operations.
Why am I not hearing anything about this? Perhaps my information is incorrect and it exposes 512e to the guest? Or is there a setting for whether the guest will see 512n/512e/4kn?
