Boot from SAN
Configuration

SAN boot enables deployment of diskless servers in an environment where the
boot disk is located on storage connected to the SAN. The server (initiator)
communicates with the storage device (target) through the SAN using the Cavium
Converged Network Adapter (CNA) Host Bus Adapter (HBA).

This chapter covers boot from SAN configuration for both iSCSI and FCoE:



iSCSI Boot from SAN

“FCoE Boot from SAN” on page 107

iSCSI Boot from SAN

Cavium 45000 Series gigabit Ethernet (GbE) adapters support iSCSI boot to
enable network boot of operating systems to diskless systems. iSCSI boot allows
a Windows, Linux, or VMware operating system to boot from an iSCSI target
machine located remotely over a standard IP network.

This section provides the following configuration information about iSCSI boot
from SAN:



iSCSI Out-of-Box and Inbox Support



iSCSI Preboot Configuration



Configuring iSCSI Boot from SAN on Windows



Configuring iSCSI Boot from SAN on Linux


