•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 6 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 5428-2

System Requirements

This section describes the system requirements for release 3.5.1 and includes the following information:

•Network Equipment, page 4

•IP Hosts, page 4

•Graphical User Interface, page 5

•iSCSI Driver Version Support, page 5

•Interoperability Information, page 5

Network Equipment

•The Gigabit Ethernet interfaces on the SN 5428-2 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 5428-2 Storage Router is connected.

•If the SN 5428-2 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 5428-2 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 5428-2. On the SN 5428-2 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.
