We have a large service provider hosting thousands of VMs with Netapp VAAI FASTclones and NFS. We tried to convince them to use VMware Linked Clones as Best Practice, but they justified not to use them with the following arguments:
“VMware linked clones are fast clones without VAAI support:
- misaligned writes (creates performance inefficiencies)
- read performance suffers especially for longer chain lengths
Just with the misaligned writes, the service provider's VMware admins worry about massive performance issues and better do not use it. “
Is it true, that we(VMware) are suffering on misaligned writes when using VMware Linked Clones?
Do we(VMware) have a read performance issue especially on longer Linked Clone chain lengths?
Any advice is welcome...
