Preboot Environment; Iscsi Boot - Dell PowerEdge R310 Technical Manual

Dell
adapters support multiple VLANs on a per-port or per-team basis, allowing very flexible network
configurations.

Preboot Environment

11.10
Broadcom 5716C LOM support Preboot Execution Environment (PXE), iSCSI BOOT, and Bootstrap Protocol
(BootP). Multi-Boot Agent (MBA) is a software module that allows your network computer to boot with the
images provided by remote servers across the network. The Broadcom MBA driver complies with the PXE 2.1
specification and is released with both monolithic and split binary images. This provides flexibility to users
in different environments where the motherboard may or may not have built-in base code.
The MBA module operates in a client/server environment. A network consists of one or more boot servers
that provide boot images to multiple computers through the network.
The Broadcom implementation of the MBA module has been tested successfully in the following
environments:
•
Red Hat® PXE Server. Broadcom PXE clients are able to remotely boot and use network resources
(NFS mount, and so forth) and to perform Linux installations. In the case of a remote boot, the Linux
universal driver binds seamlessly with the Broadcom Universal Network Driver Interface (UNDI) and
provides a network interface in the Linux remotely-booted client environment.
• Intel APITEST. The Broadcom PXE driver passes all API compliance test suites.
• MS-DOS UNDI. The MS-DOS Universal Network Driver Interface (UNDI) seamlessly binds with the
Broadcom UNDI to provide a network adapter driver interface specification (NDIS2) interface to the
upper layer protocol stack. This allows computers to connect to network resources in an MS-DOS
environment.
•
Remote Installation Service (RIS). The Broadcom PXE clients are able to remotely boot to a Windows
Server 2003 (SP1 and older) system running RIS to initialize and install Windows Server 2003 and prior
operating systems. To extend functionalities beyond basic network connectivity when loading an
operating system through RIS, see Using the NetXtreme II Monolithic Driver.
• Windows Deployment Service (WDS). For Windows Server 2003 SP2, RIS was replaced by WDS, which
offers a Broadcom PXE client to install Windows operating systems, including Windows Server 2008
and Windows Server 2008 R2. To extend functionalities beyond basic network connectivity when
loading an operating system through WDS, see Using the NetXtreme II Monolithic Driver.
• Automated Deployment Service (ADS). The Broadcom PXE client can connect to a Windows Server
2003 system and run a deployment agent that allows one to perform some administrative functions,
including, but not limited to, deploying a Windows Server 2003 image. To extend functionalities
beyond basic network connectivity when loading an operating system through ADS, see Using the
NetXtreme II Monolithic Driver.

iSCSI Boot

11.11
BCM5716C offers iSCSI boot technology, which allows a diskless boot of OS from an iSCSI target machine
remotely located over a standard IP network (LAN or SAN). The benefits are:
•
Lower hardware purchase cost—no disk, less space
•
Reduced operating cost—less power/cooling
•
Greater HW reliability—no disk failures
•
Simplified management—centralized upgrades
•
Greater SW integrity/availability—fewer backups
•
Faster recovery—no need to rebuild servers
•
Protocol Simplicity—standard storage interface
•
Greater Security—SAN isolation prevents hacking
•
Major Operating System support
•
Appears to the host OS as a local disk
