iSCSI protocol overview
iSCSI is a SCSI transport protocol for mapping of block-oriented storage data over TCP/IP networks
through iSCSI protocol data units (PDUs). The iSCSI protocol enables universal access to storage devices
and storage area networks (SANs) over standard Ethernet-based TCP/IP networks. These networks m ay
be dedicated networks or may be shared with traditional Ethernet applications. IP LAN/WAN routers
and switches can b e used to extend the IP storage net work to a wide area of applications such as
synchronous and asynchronous remote disk copy or tape backup and restore.
iSCSI in a SAN
Although th

Typical network structure
When you add iSCSI to a large SAN, you must configure and manage two data protocols: TCP/IP and
Fibre Channel. IP hosts with iSCSI initiators access C-Series IP Services through an IP network connected
to the C-Series Gigabit Ethernet (GbE) interface. The C-Series IP Services access Fibre Channel storage
devices connected to the Fibre Channel interfaces through the FC ports within the C-Series chassis or
through the FC ports of the IP switch. Figure 1 shows a typical IP/Fibre Channel network.
e iSCSI protocol is written as a complete data transport from host to storage, this guide only
he current H P suppor ted topology of iSCSI hosts to Fibre Channel storage using the C-Series I P
rvices Modules (IPS-4, IPS-8) , Multi-protocol Services Module (14/2), and the 9216i switch.
iSCSI In
itiator
With the IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Modu le ( 1 4/2 ), and MDS
9216i switch, the IP host uses an iSCSI initiator to enable target resource recognition and a t tachment.

directly connected to the SAN.
LUN setup and LUN masking can now be configured with this WWPN. The iSCSI Initiator then sees these
storage resources (LUNs) as if they were local drives attached directly to the server.
IP network
The I P network is the infrastructure used to transfer data between the iSCSI Initiator and the C-Series IP
Services via TCP/IP. LA N switches tend to be Ethernet-based, supporting speeds from 10 Mb/s to 10
Gb/s, using copper and optical interfaces ranging in size from a few ports to hundreds of ports.
LAN switches typically support TCP/IP and other protocols, including TCP/UDP, IPX, and AppleTalk.
Other features found in many LAN switches include support for voice-over-IP (VoIP), quality of service
(QoS), bandwidth management and reporting, multi-cast and jumbo frames. With the advent of SCSI
storage data now being transferred within an IP network, it is important to recognize and understand the
level of service necessary to avoid loss of data.
Part of the appeal that iSCSI brings to the storage market is low cost, standardized network adapters
and topology hardware, in addition to years of expertise developed i n deploying these networks.
However, it should be stressed that existing networks must be evaluated for suitability regarding their
capacity to support iSCSI storage. In any deployment, HP recommends using a dedicated Gigabit
Ethernet network bet ween iSCSI Initiators and the C-Series I P Storage Services Modules (IPS-4, IPS-8),
Multi-protocol Services Module (14/2), or MDS 9216i switch. This ensures adequate performance as
ries IP Services connect directly to HP’s Fibre Channel SAN storage via an IP–to–worldwide port
(WWPN) translation provided by the C-Series IP Services. With this transparent SCSI forwarding,
ibre Channel SAN Storage recognizes this WWPN as it would from any Fibre Channel HBA
10
well as helping to provide data security. An alternative is to use IPSec to secure the connection, although
therewillbeaperformanceimpact.

this point, the SCSI commands are transferred from a n IP network into a Fibre Channel network and
warded to the intended target. Figure 2 illustrates an IP Storage Services Modules (IPS-4, IPS-8),

Fibre Channel SAN
A SAN is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any
interconnection of servers and storage. SANs are built to incorporate the best of both storage and
networking interfaces: fast and efficient communications optimized for movement of large amounts of
data, but with access to a wide range of other servers and storage devices on the network.
The C-Series IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services Module (14/2), and
MDS 9216i switch are suppor ted on any currently suppor ted HP infrastructure C-Series switch fabric.

Multi-pathing
Multi-pathing is supported on EVA4000/6000/8000 only in a Windows environment using the Microsoft
Multipath I/O driver (MPIO), supported with iSCSI. Without multi-path capabilities, the iSCSI initiator can
only access one path of the storage controllers, which disables controller failover protection.

Configuring SANs with C-Series switches and iSCSI in a
Windows environment
To configure the C-Series IP Storage Ser vices Modules (IPS-4, IPS-8), M ulti-protocol Services Module
(14/2)andMDS9216iswitchinanHPFibreChannelSAN:
1. Enable iSCSI on the C-Series switch
2. PresentiSCSIhostsasvirtualFChosts
3. Install the Microsoft iSCSI initiator
14
4. Zone the iSCSI initiator WWPN with Fibre Channel storage WWPN
5. Create an iSCSI host
These procedures are described in the following sections. They enable you to quickly set up a basic
connection between an iSCSI server and Fibre Channel storage. For advanced configuration parameters
such as CHAP, V RRP, or VSANs, refer to the appropriate Cisco technical manuals and your iSCSI Initiator
documentation.
NOTE:
This section uses Microsoft Windows in examples where host software is configured for iSCSI. To
configure iSCSI for other operating systems, consult the host software documentation. The i SCSI
configuration procedures for C-Series products are independent of the host operating system.
Enabling iSCSI on the C-Series IP Storage Services Modules (IPS-4, IPS-8),
Multi-protocol Ser vices Module (14/2), and MDS 9216i switch
To configure the iSCSI feature, you must explicitly enable iSCSI on the required switches in the fabric. By
default, this feature is disabled in all switches in the C-Series family.
The configuration and verification commands for the iSCSI feature are available only when iSCSI is
enabled o n a switch. When you disable iSCSI, all related configurations are automatically discarded.
To enable iSCSI on any participating switch using CLI:
1. Enter configuration mode: switch# config t
2. Enable iSCSI on the switch: switch# iscsi enable
To disable iSCSI on any participating switch using CLI: switch# no iscsi enable
Enabling the iSCSI interface
Before iSCSI processing begins on any physical Gigabit Ethernet interface, you must enable the
corresponding iSCSI interface.
To enable an iSCSI interface:
1. Create and enable the required Gigabit Ethernet interface (slot 2, p ort 2) :
switch# config terminal
switch(config)# interface gigabitethernet 2/1
switch(config-if)# no shutdown
2. Create and enable the required iSCSI interface:
switch(config-if)# exit
switch(config)# interface iscsi 2/1
switch(config-if)# no shutdown
Configuring the Gigabit Ethernet interface
iSCSI relies on TCP/IP for network connectivity. On each C-Series IP Storage Services Modules (IPS-4,
IPS-8), Multi-protocol Services Module (14/2), and MDS 9216i switch, connectivity is provided in the
form of Gigabit Ethernet interfaces that are appropriately confi gured.
NOTE:
Gigabit Ethernet ports on any C-Series IP Storage Services Modules (IPS-4, IPS-8), Multi-protocol Services
Module (14/2), and MDS 9216i switch should not be configured in the same Ethernet broadcast
domain as the management Ethernet port. HP recommends that you configure them in a different
broadcast domain, either by using separate standalone hubs or switches or by using separate VLANs.
