HP NC382m HP Broadcom iSCSI Boot for NC382x Adapters User Guide - Page 4

Overview Overview The HP-BRCM iSCSI boot feature allows a server to boot from a remote disk that supports Microsoft iSCSI Software Initiator (known as the iSCSI target) on a Storage Area Network (SAN) without having to directly attach a boot disk. Booting from a remote disk on a SAN allows the boot process to be centralized and consolidates equipment resources. Unlike other implementations, iSCSI boot does not require a separate DHCP server or a PXE server. Accelerated iSCSI Boot for Windows HP Accelerated iSCSI capability can be used with HP NC-Series Broadcom iSCSI Boot Package for Windows. All accelerated iSCSI commands are handled by the adapter's HP iSCSI HBA driver. This feature is applied to all HP Multifunction Gigabit Ethernet Server Adapters at no additional cost for standup and mezzanine adapters; however, some embedded HP Multifunction Gigabit Ethernet Server Adapters require a ProLiant Accelerated iSCSI Pack license. For more information see the HP ProLiant Accelerated iSCSI for Windows User Guide. Limitations • A system crash may result if you bring down a network adapter that is iSCSI-boot enabled. The Windows Server 2003 SP2 operating system prevents you from disabling iSCSI-booted adapters. • File system access lapses (due to unplugging the cable) for time critical "keep alive" processes (svchost) may cause reboots. • Network adapter property changes (for example, Link Speed) can cause unrecoverable configuration changes, which may prevent booting. • iSCSI target configuration changes (for example, Adapter Name) causes boot failure if you do not change the iSCSI boot configuration as well. • Adapter failover during the software installation or the boot phase is not possible. • Discovery protocols, such as Internet Storage Name Service, and Service Location Protocol are not supported during iSCSI boot installs. System requirements The following system requirements support HP IPv4 iSCSI boot for Windows: Supported operating systems • Windows Server 2008 R2 • Windows Server 2008 SP2 • Windows Server 2008 x64 SP2 Overview 4
