SAN Boot
SAN Boot is a network storage management system that stores data (including servers' operating systems) totally on storage systems. Specifically, operating systems are installed on and booted from SAN storage devices. SAN Boot is also called Remote Boot or boot from SAN.
SAN Boot can help to improve system integration, enable centralized management, and facilitate recovery.
- Server integration: Blade servers are used to integrate a large number of servers within a small space. There is no need to configure local disks.
- Centralized management: Boot disks of servers are centrally managed on a storage device. All advanced management functions of the storage device can be fully utilized. For example, the snapshot function can be used for backup. Devices of the same model can be quickly deployed using the snapshot function. In addition, the remote replication function can be used for disaster recovery.
- Quick recovery: Once a server that is booted from SAN fails, its boot volume can be quickly mapped to another server, achieving quick recovery.
