Introduction
Introduction
The Cisco SN 5428 Storage Router provides universal access to storage over IP networks. The storage
router software controls the operation of the Cisco SN 5428 Storage Router. You can configure the
software to provide one of two types of access to storage over IP networks; either SCSI routing or
Transparent SCSI routing.
SCSI routing provides IP hosts with access to Fibre Channel (FC) storage devices, using iSCSI protocol.
The iSCSI protocol is an IETF-defined protocol for IP storage (ips).
Note
For more information about the iSCSI protocol, refer to the IETF standards for IP storage at
http://www.ietf.org.
With SCSI routing, storage device access is managed primarily in the SN 5428. (See Figure 1.)

Storage access is managed
in the SN 5428.
Transparent SCSI routing provides IP hosts with transparent access to intelligent storage arrays using
iSCSI protocol; that is, each IP host is presented as an FC host to an intelligent storage array. With
transparent SCSI routing, availability of storage devices is managed primarily in the intelligent storage
array. (See Figure 2.)

In addition to providing services for accessing storage over IP networks, the SN 5428 Storage Router
software provides the following services:
•
VLAN Access Control—provides IP access control to storage based on a VLAN identifier (VID)
number (in addition to access control through access lists)
•
Authentication—provides iSCSI, Enable and Login authentication using AAA authentication
methods

System Requirements
•
High Availability (HA)—provides the ability to group storage routers in a cluster for intelligent
failover and other cluster-related functions (for SCSI routing only)
•
E_Port with FC Fabric Zoning—provides the ability to connect FC ports to FC switches and
participate in fabric zoning, manage zoning, and support zone mergers
•
SNMP/MIB support—provides network management of the SN 5428 through SNMP using selected
MIBs
•
Gigabit Ethernet Interface features—provides the ability to assign a management IP address per
Gigabit Ethernet interface, multiple IP addresses per SCSI routing instance, and an optional
secondary Gigabit Ethernet interface per IP address used for SCSI routing or SN 5428 management
•
Buffer credit extension—enables the SN 5428 to donate buffer credits from a donor port to selected
FC ports
•
Secure Sockets Layer (SSL) support—provides HTTPS connection for secure access through the
web-based GUI
•
Secure Shell (SSH) protocol version 2 support—provides high encryption and authentication for
interactive management sessions, and is a common replacement for Telnet
•
Routing Information Protocol (RIP) listening support—allows the SN 5428 to learn dynamic
routing using RIP (version 1 or version 2) listening
•
Service Location Protocol (SLP) support—provides the ability to advertise targets of specified SCSI
routing instances to initiators or servers that use SLP
•
Internet Storage Name Service (iSNS) support—provides the ability to register iSCSI targets with
an iSNS server, allowing iSCSI initiators to dynamically discover available storage targets
•
LUN Trespass feature—provides a LUN failover feature for selected storage arrays that operate on
the active/passive port model. When enabled, the trespass feature provides a redundant path from
the storage router to the storage array by allowing the storage router to detect a path failure to a
storage array port and perform the necessary operations to fail LUNs over to the other port on the
storage array without using any multi-path software. See the “LUN Trespass Feature” section on
page 5 for details about storage array interoperability.
•
TCP Window Tuning—provides the ability to maximize bandwidth across the network by
automatically setting the local TCP receive window size to the remote TCP receive window size
without user intervention
•
A command-line interface (CLI) and a web-based GUI—provides user interfaces for configuration
and maintenance of an SN 5428

System Requirements
Network Equipment
•
The Gigabit Ethernet interfaces on the SN 5428 Storage Router use a flow control mechanism for
stopping and starting traffic that prevents the loss of data. Flow control should also be turned on at
the router’s Gigabit Ethernet interfaces where the SN 5428 Storage Router is connected.
•
If the SN 5428 Storage Router is participating in a cluster (SCSI routing only), and the HA or
management interfaces are plugged into a switch that has Spanning Tree Protocol (STP) enabled,
the storage router should be considered as an end station and the affected ports on the switch should
be configured appropriately. For example, set “portfast” on Cisco switches to cause the ports to
immediately switch from blocking mode to forwarding mode. This helps prevent time-outs, which
can cause unexpected behavior when storage routers join a cluster.
IP Hosts
To ensure the best performance for the SN 5428 Storage Router and the iSCSI drivers, the extended
windowing feature of TCP and the receive and transmit flow control feature of the Gigabit Ethernet
driver should be enabled on all IP hosts connecting to the SN 5428. On the SN 5428 Storage Router, you
can use the CLI show scsirouter all connection tcp command to display the current and maximum TCP
window size for each connected host.
Graphical User Interface
The SN 5428 Storage Router web-based GUI officially supports the following browsers. The browser
must be enabled to support JavaScript and style sheets.

Installation Notes
Step 6
At Select next boot version, select the new software version. If you have made configuration changes
to the storage router that have not been saved, click the Save unsaved changes? checkbox to save any
configuration changes that have been made but not saved to the storage router’s bootable configuration
Step 7
Click Reset System.
Step 8
After the storage router has rebooted, verify that it is running the new software. (See the “Determining
the Storage Router Software Version” section on page 7.)
If the storage router is deployed for transparent SCSI routing, the upgrade to version 3.5.3 from any
version prior to 3.3.1 places the storage router in dynamic mode. Dynamic mode resets iSCSI
client-to-FC WWPN bindings upon reboots or iSCSI logouts, and requires an intelligent storage array
that supports an extended iSCSI FC PLOGI frame. To change the mode of an existing transparent SCSI
routing deployment, you must completely clear the storage router configuration. When the storage router
reboots, follow the prompts from the initial configuration script to complete the new system
configuration and select the desired mode for transparent SCSI routing.
For more information about clearing the storage router configuration, see the section “Resetting the
System” in Chapter 10, “Maintaining and Managing the SN 5428 Storage Router,” of the Cisco SN 5428
Storage Router Software Configuration Guide, Release 3.4.

SCSI
•
CSCee03436
An open to the device may fail when running the SN 54282 Storage Router with an IP host running
Windows 2000 and accessing a STK9840 tape device.
Workaround. None. This problem is resolved in release 3.5.3.
TCP-IP
•
CSCed66780
If a failover is performed when the storage router is running in a cluster, the IP hosts may
occasionally be unable to connect to the IP addresses on the current master.
Workaround: None. This problem is resolved in release 3.5.3.
vxworks
•
CSCee36193
TCP connections can be broken with RST packet attacks. A TCP connection can be dropped by
sending an RST packet within the TCP window. For long lived connections such as iSCSI, this opens
the possibility of a denial of service if an attacker continually causes the TCP connection to be
dropped. Cisco issued a security advisory for this problem.
Workaround: None. The problem is resolved in release 3.5.3, solving the security advisory
previously issued.
