Release Notes for Cisco SN 5428 Storage Router Release 3.5.3

OL-6542-01

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.
