Direct SAN Access for VMware
If your VMs are located on a Fiber Channel or an iSCSI device, NAKIVO Backup & Replication can use the Direct SAN Access transport mode for VMware backup and replication. Using this mode, NAKIVO Backup & Replication reads data directly from/writes data to Fiber Channel and iSCSI SAN devices.
In order to use Direct SAN Access transport mode, NAKIVO Backup & Replication should be deployed on the machine that is physically connected to a SAN. By default, the product automatically determines if direct SAN access is available, and uses it for VM backup and replication. You can also force VM backup and replication jobs to only use the Direct SAN Access mode so that jobs do not fail over to the network mode, if SAN becomes unavailable.
NAKIVO Backup & Replication relies on the VMware VDDK library to provide SAN support and does not make any write/modification operations on the SAN LUNs. VM data is read directly from LUNs over Fiber Channel/iSCSI, then processed, and transferred to a destination.
The Direct SAN Access transport mode significantly increases data transfer speeds, thus making backups faster while removing the load from your production network.
