Overview

iSCSI protocol

The HP iSCSI protocol transports block-level storage requests over TCP connections. Using the iSCSI
protocol, systems can connect to remote storage and use it as a physical disk although the remote storage
provider or target may actually be providing virtual physical disks. HP Accelerated iSCSI supports all
targets that are certified and supported by Microsoft iSCSI Software Initiator.

HP Multifunction Server Adapters can be enabled as iSCSI devices or virtual iSCSI host bus adapters
(HBAs). iSCSI HBAs provide the capability to run iSCSI protocol over offloaded TCP connections. By
offloading the TCP connection processing to an HP Multifunction Server Adapter, CPU utilization is
reduced allowing additional processing capacity for applications.

HP Accelerated iSCSI capability

The HP Accelerated iSCSI capability is available as a standard feature with standup and mezzanine HP
Multifunction Server Adapters and HP Multifunction Server Adapters for HP BladeSystem servers. It is
available as a licensable option, through the purchase of an HP ProLiant Accelerated iSCSI license, for
embedded HP Multifunction Server Adapters.

iSCSI supported operating systems

iSCSI capabilities are available on the following operating systems:

• Windows Server 2008 Enterprise

• Windows Server 2008 x64 Enterprise

• Windows Server 2003

• Windows Server 2003 x64

To enable iSCSI on adapters running Windows Server 2003 and Windows Server 2003 x64 systems,
the Microsoft® iSCSI Software Initiator version 2.0 or later software must be installed. This software is
required to configure the iSCSI protocol, including discovery portals, iSCSI targets, authentication, and so
on.

For systems running Windows Server 2003 (SP1) or Windows Server 2003 x64 (SP1), you must upgrade
to Service Pack 2 or later.

Accelerated iSCSI is not supported on HP NC-Series 10 GbE adapters in this release.

Supported iSCSI targets

HP Accelerated iSCSI supports all targets that are certified and supported by Microsoft iSCSI Software
Initiator.

Configuring an iSCSI device

iSCSI configuration through the NCU

Complete the steps in the following sections to enable and configure an iSCSI device or to view iSCSI

Install the Network Configuration Utility software

information through the NCU.

If you do not have HP NCU software installed on your server, complete the following steps to install the
NCU for Windows operating systems:

1. Go to the HP website (http://www.hp.com).

2. Click Software & Driver Downloads from the left menu bar.

3. Type the product name in the For product box and press Enter. For example, type NC373T.

4. Select an operating system.

5. Click HP Network Configuration Utility.

6. Click download and save the HP SoftPaq (sp#####.exe) file to a directory on your hard drive. The

SoftPaq file is a self-extracting executable with a file name based on the SoftPaq number.

7. Click the SoftPaq file to extract the files and then open the cmponent.htm file.

iSCSI Settings tab

To enable iSCSI:

1. Select an HP Multifunction Adapter in the NCU Main window and click Properties to display the

Multifunction Adapter Properties Settings tab. Alternatively, hold down the Alt key and enter p to
display the Settings tab.

Configuring an iSCSI device 6

2.

Select Enable iSCSI Device to enable iSCSI on the multifunction adapter. iSCSI cannot be enabled on
the device if the adapter is in an Automatic, 802.3ad Dynamic with Fault Tolerance, or Switch­Assisted Load Balancing with Fault Tolerance (SLB) team.

This control is not available for iSCSI booted systems. In an iSCSI Booted system, the interfaces
containing iSCSI option ROM are shown under "iSCSI Devices" without selecting Enable iSCSI
Device under the Settings tab. The Enable iSCSI Device option for an iSCSI Booted interface is grayed
out and is not available. If the NCU detects that the system was booted over iSCSI, the following
message prompts you to install an Accelerated iSCSI Pack for Embedded Multifunction Gigabit
Server Adapters license if one is not detected.

Configuring an iSCSI device 7

3.

(Optional steps). Type a user-defined MAC address for the iSCSI device in the Locally Administered
Address box. The default MAC address is used if an address is not entered. This control is not

available for iSCSI booted systems.

4. Click iSCSI IP Settings. The iSCSI IP Settings window appears so that you can specify how the IP

Address is obtained. This control is not available for iSCSI booted systems.

5. On the iSCSI IP Settings window, select one of the following:
a. Obtain an IP Address automatically. This is the default. If this option is selected, DHCP is used to

acquire an IP configuration for the iSCSI device.

b. Use the following IP address. This option allows you to specify the IP configuration for the iSCSI

device. The IP address MUST be different from IP addresses that are assigned to other iSCSI
devices and Ethernet adapters.

— IP Address. Enter the IPv4 address (dotted decimal).
— Subnet Mask. Enter the network subnet mask (dotted decimal).
— Default Gateway. Enter the default route.

6. Click OK to save all changes and return to the Multifunction Adapter Properties Settings tab.

After a Multifunction Server Adapter is enabled as an iSCSI device, it becomes a virtual iSCSI HBA. These
devices are displayed on the iSCSI Devices tab on the NCU Main window.
