Question

What is lanfree

Accepted Answer

Lanfree is a backup method that allows data to be transferred directly between storage devices without using the LAN network.

Lanfree is a feature in TSM (Tivoli Storage Manager) that enables data transfer between storage devices without utilizing the LAN network.
It improves backup performance by reducing network congestion and utilizing dedicated storage paths.
Lanfree backups require additional hardware, such as Fibre Channel or SCSI adapters, to establish direct connections between the backup server and storage devices.
By bypassing the LAN, lanfree backups can achieve faster data transfer rates and reduce the impact on the network infrastructure.
Example: In a lanfree configuration, a TSM backup server can directly write data to a tape library using a dedicated Fibre Channel connection, bypassing the LAN.
