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

• Windows Server 2008 x64

• 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.

To enable iSCSI on adapters running on Windows Server 2003 (SP1) and Windows Server 2003 x64
(SP1), an updated Storport storage driver from article number KB932755 must be downloaded from the
Microsoft (http://www.microsoft.com

) website.

Supported iSCSI targets

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