1 Introduction This document shows how to configure Dell™ Networking S5000 switches for use as a dedicated iSCSI SAN with Dell SC Series storage using Dell best practices. 1.1 Audience This switch configuration guide describes an optimal configuration following Dell best practices for an SC Series iSCSI SAN and is intended for storage or network administrators and deployment personnel. 1.2 Switch details The table below provides an overview of the switch configuration. Table 1 Switch specifications Dell Networking S5000 Switch vendor Dell Switch model S5000 Switch firmware 9.9.9.0 or later Note: For proper functionality, the switch must be at the firmware version shown in the table above before proceeding with this configuration. Using previous firmware versions may have unpredictable results. The latest firmware updates and documentation can be found at: www.force10networks.com. This site requires a login.

2 Dell recommended switch configuration These steps outline how to configure two S5000 switches for use as an iSCSI SAN with SC Series storage. 2.1 Hardware configuration 1. Power on the two switches. 2. Connect a serial cable to the serial port of the first switch. 3. Using any terminal utility, open a serial connection session to the switch. 4. Open the terminal emulator and configure it to use the serial port (usually COM1, but this may vary depending on the system). Configure serial communications for 9600,N,8,1 and no flow control. 2.2 Delete startup configuration Note: This example assumes a switch at its default configuration settings. Using the delete startup- config command will set the startup configuration file to its default settings. You should always backup your configuration settings prior to performing any configuration changes FTOS>enable FTOS#delete startup-config Proceed to delete startup-config [confirm yes/no]yes FTOS#reload System configuration has been modified. Save? [yes/no]no Proceed with reload [confirm yes/no]yes Note: The switch will reboot. 2.3 Disabling Data Center Bridging (DCB) configuration Note: For non-DCB environments, DCB must be manually disabled using the following steps: FTOS>enable FTOS#configure FTOS(conf)#no dcb enable FTOS(conf)#exit FTOS#copy running-config startup-config

2.4 Configure out of band (OOB) management port FTOS>enable FTOS>#config FTOS(conf)#interface Managementethernet 0/0 FTOS(conf-if-ma-0/0)#no shutdown FTOS(conf-if-ma-0/0)#ip address ipaddress mask FTOS(conf-if-ma-0/0)#exit 2.5 Configure route for OOB management port (optional) FTOS (conf)#management route X.Y.Z.0 /24 A.B.C.1 Note: X.Y.Z.0 is the network your management system is connecting from and A.B.C.1 is the gateway for the switch. If your management system is on the same subnet as the switch, the previous step may be omitted. The example above assumes a class C subnet mask. 2.6 Configure login credentials FTOS(conf)#username admin password yourpassword privilege 15 FTOS(conf)#enable password yourpassword 2.7 Enable switch ports Option 1: You can enable ports individually by entering the port number FTOS(conf)#interface tengigabitethernet 0/0 FTOS(conf-if-te-0/0)#switchport FTOS(conf-if-te-0/0)#no shutdown FTOS(conf-if-te-0/0)#exit Option 2: You can enable multiple ports at once using the “range” parameter FTOS(conf)#interface range tengigabitethernet 0/0 – 47 Note: The message below will be displayed if there are FC ports. % Warning: Non-existing ports (non configured) are ingnored by interface-range

FTOS(conf-if-range-te-0/0-47)#switchport FTOS(conf-if-range-te-0/0-47)#no shutdown 2.8 Enable Jumbo Frames FTOS(conf-if-range-te-0/0-47)#mtu 12000 2.9 Enable flow control FTOS(conf-if-range-te-0/0-47)#flowcontrol rx on tx off 2.10 Configure spanning tree on edge ports Note: Use the following command only on server- and storage-connected edge ports. FTOS(conf-if-range-te-0/0-47)#spanning-tree rstp edge-port FTOS(conf-if-range-te-0/0-47)#exit FTOS(conf)#protocol spanning-tree rstp FTOS(conf-rstp)#no disable FTOS(conf-rstp)#exit 2.11 Configure VLAN Note: Dell recommends assigning a unique vlan_id (between 2-4094) for each switch fabric. For example, assign VLAN 100 on the first switch and VLAN 200 on the second switch. The following example assigns all the ports to the VLAN, however, you may also assign individual ports to the VLAN after they are enabled (Section 2.7). If you prefer to use the default VLAN, then you may skip this section entirely. FTOS(config)#interface vlan vlan_id FTOS#(config-if-vl-###)#no shutdown FTOS#(config-if-vl-###)#untagged tengigabitethernet 0/0-47 FTOS#exit

2.12 Save configuration FTOS#copy running-config startup-config 2.13 Configure additional switch Repeat the commands from Section 2 to configure the second switch.

3 Configure UPM ports as Ethernet pass-through (optional) The FC ports on the Unified Port Module (UPM) can be configured as Ethernet pass-through. Use this section only if the UPM module is used. The 12 ports are divided into six port groups numbered 0-5. Two ports in each port group can be configured separately as FC or Ethernet pass-through. Note: This operation requires a reload for the changes to take effect. 3.1 View the current configuration Use this command to view the current mode of the ports and also the port group mapping. FTOS# show system stack-unit 0 port-group portmode PortGroupId Ports Mode(Curr Boot) Mode(Next Boot) 0 0,1 FC FC 1 2,3 FC FC 2 4,5 FC FC 3 6,7 FC FC 4 8,9 FC FC 5 10,11 FC FC 3.2 Configure port group 0 as Ethernet pass-through FTOS(conf)# stack-unit 0 port-group 0 portmode Ethernet Changing port mode on slot 0 port-group 0 will make interface configs of 0 and 1 obsolete after a save and reload. [confirm yes/no]:yes Please save and reload for the changes to take effect. Note: Save and reload is required.

3.3 To revert Ethernet pass-through to FC ports FTOS(conf)# no stack-unit 0 port-group 0 portmode ethernet Changing port mode on slot 0 port-group 0 will make interface configs of 0 and 1 obsolete after a save and reload. [confirm yes/no]:yes Please save and reload for the changes to take effect. Note: Save and reload is required.
