Veeam Black Technology: Direct NFS Access
I’ve been working with more VMware environments lately, and I’m noticing a clear trend: NFS datastores are becoming mainstream. It used to be that only NetApp enthusiasts would seriously consider NFS for VMware, but times have changed. With the rise of hyper-converged infrastructure, major platforms like Nutanix and Cisco HyperFlex are now delivering storage to VMware exclusively through NFS.
This shift has always been a bit problematic for backup performance. When you’re using NFS datastores, your only option for virtual machine backups has been the network transport method (NBD), which caps you at just 40% of VMKernel’s total network throughput. Even with plenty of bandwidth available, you’d hit that performance ceiling every time.
