Introduction
Cisco's iSCSI drivers or the Miscosoft iSCSI driver, which reside on the server, are a key component of the iSCSI solution. These iSCSI drivers intercept SCSI commands, encapsulate them into IP packets, and redirect them to the Cisco SN 5420, Cisco SN 5428, Cisco SN5428-2, or Cisco MDS/IPS-8. This document provides sample configurations for a Win2k host to a Cisco MDS 9000.
Prerequisites
Requirements
Before attempting this configuration, ensure that you meet these prerequisites:
-
Before you create your iSCSI configuration on the MDS 9000, you need to install the iSCSI driver that is compatible to your Windows 2000 version. The most current version of the driver can be found at the Cisco iSCSI Driver (registered customers only) page on Cisco.com. The README.txt file is included in the driver zip file. The README contains information about the license agreement, driver installation and configuration instructions, and a technical overview of the driver architecture.
-
The operating system requirements and patch requirements are described in the System Requirements section of Cisco iSCSI Driver for Microsoft Windows 2000.
Components Used
The information in this document is based on these software and hardware versions:
-
Host with Windows 2000 (with Service Pack 3)
-
Cisco iSCSI Driver 3.1.1 for Windows 2000
-
Microsoft iSCSI driver 1.0.5a for Windows 2000
-

Background Theory
The IP Storage module provides IP hosts access to Fibre Channel (FC) storage devices. The IP Storage module is DS-X9308-SMIP. It provides transparent SCSI routing. IP hosts that use the iSCSI protocol can transparently access SCSI (FCP) targets on the FC network. The IP host sends SCSI commands encapsulated in iSCSI Protocol Data Units (PDUs) to a MDS 9000 IP Storage port over a TCP/IP connection. On the IP Storage module, connectivity is provided in the form of Gigabit Ethernet (GE) interfaces that are appropriately configured. The IP Storage module enables you to create virtual iSCSI targets and maps them to physical FC targets available in the FC SAN. It presents the FC targets to IP hosts as if the physical targets were locally attached.
Each iSCSI host that requires access to storage by way of the IP Storage module needs to have a compatible iSCSI driver installed. With the iSCSI protocol, the iSCSI driver allows an iSCSI host to transport SCSI requests and responses over an IP network. From the perspective of a host operating system, the iSCSI driver appears to be a SCSI transport driver similar to a FC driver for a peripheral channel in the host. From the perspective of the storage device, each IP host appears as a FC host.
Routing SCSI from the IP host to the FC storage device consists of these main actions:
-
Transporting iSCSI requests and responses over an IP network between hosts and the IP Storage module.
-
Routing SCSI requests and responses between hosts on an IP network and the FC storage device (converting iSCSI to FCP and the reverse). This routing is performed by the IP Storage module.
-
Transporting FCP requests or responses between the IP Storage module and FC storage devices.
The IP Storage module does not import FC targets to iSCSI by default. Either dynamic or static mapping must be configured before the IP Storage module makes FC targets available to iSCSI initiators. When both are configured, statically mapped FC targets have a configured name. In this configuration, examples of static mapping are provided.
With dynamic mapping, each time that the iSCSI host connects to the IP Storage module, a new FC N port is created, and the nWWNs and pWWNs allocated for this N port may be different. Use the static mapping method if you need to obtain the same nWWNs and pWWNs for the iSCSI host each time it connects to the IP Storage module. Static mapping can be used on the IP Storage module to access intelligent FC storage arrays that have access control and Logical Unit Number (LUN) mapping/masking configuration based on the initiator's pWWNs and/or nWWNs.
You can control access to each statically-mapped iSCSI target by specifying a list of IP Storage ports on which they will be advertised, and specifying a list of iSCSI initiator node names allowed to access it. FC zoning-based access control and iSCSI-based access control are the two mechanisms by which access control can be provided for iSCSI. Both methods can be used simultaneously. In this configuration, default zoning has been permitted for specific VSAN. IP Storage modules use both iSCSI node name-based and FC zoning-based access control lists to enforce access control during iSCSI discovery and iSCSI session creation.
iSCSI discovery occurs when an iSCSI host creates an iSCSI discovery session and queries for all iSCSI targets. The IP Storage module returns only the list of iSCSI targets that the iSCSI host is allowed to access based on the access control policies.
iSCSI session creation occurs when an IP host initiates an iSCSI session. The IP Storage module verifies if the specified iSCSI target (in the session login request) is a static mapped target, and if true, verifies that the IP host's iSCSI node name is allowed to access the target. If the IP host does not have access, its login is rejected.
The IP Storage module, then creates a FC virtual N port (the N port may already exist) for this IP host, and does a FC name server query for the FCID of the FC target pWWN that is being accessed by the IP host. It uses the IP host virtual N port's pWWN as the requester of the name server query. Thus, the name server does a zone-enforced query for the pWWN and responds to the query. If the FCID is returned by the name server, the iSCSI session is accepted. Otherwise, the login request is rejected.
