ISCSI BOOT
Broadcom NetXtreme II Gigabit Ethernet adapters support iSCSI boot to enable network boot of operating systems to
diskless systems. iSCSI boot allows a Windows, Linux, or VMware operating system boot from an iSCSI target machine
located remotely over a standard IP network.
For both Windows and Linux operating systems, iSCSI boot can be configured to boot with two distinctive paths: non-offload
(also known as Microsoft/Open-iSCSI initiator) and offload (Broadcom’s offload iSCSI driver or HBA). Configuration of the
path is set with the HBA Boot Mode option located on the General Parameters screen of the iSCSI Configuration utility.
See Table 1 for more information on all General Parameters screen configuration options.
SUPPORTED OPERATING SYSTEMS FOR ISCSI BOOT
The Broadcom NetXtreme II Gigabit Ethernet adapters support iSCSI boot on the following operating systems:
• Windows Server 2008 and later 32-bit and 64-bit (supports offload and non-offload paths)
• Linux RHEL 5.5 and later, SLES 11.1 and later (supports offload and non-offload paths)
