Configure Data Center Bridging Ensure that you have properly configured your environment (switch fabric) for all DCB-enabled devices, according to the requirements described in the following section. Requirements For DCB to function correctly, your configuration must meet the following requirements: • All group members must be 10Gb arrays. • All group members must be running PS Series firmware version 6.0 or later. • Initiator and target devices, as well as all the network switches between the initiators and the targets, must support DCB. All devices must be configured for DCB from end to end, including: - From the host's CNA card (edge-port) to the network switch - From the network switch to the array (edge-port) - Everything else in between (if using multiple switches) • All of the network devices, initiators, targets (if non-EQL targets), and switches in the network configuration, such as PFC (Priority Flow Control), iSCSI TLV (Type-Length-Value), and ETS (Enhanced Transmission Selection), must be supported. • Even if all the attached network switches fully support DCB, you must configure DCB properly on the network switches for the configuration to work correctly. Additional Information Dell strongly recommends that you read the following white papers for more information about configuring DCB: • The Data Center Bridging: Standards, Behavioral Requirements, and Configuration Guidelines with Dell EqualLogic iSCSI SANs white paper contains information about the DCB requirements and configuration guidelines. You can download the paper from: http://en.community.dell.com/techcenter/storage/w/wiki/4396.data-center-bridging-standards-behavioral-requirements-andconfiguration-guidelines-by-sis.aspx • The EqualLogic DCB Configuration Best Practices white paper contains the DCB requirements for EqualLogic, to ensure that DCB is properly enabled or disabled across all devices, and to assist with identifying and resolving basic DCB configuration issues in the EqualLogic SAN. You can download the paper from: http://en.community.dell.com/techcenter/storage/w/wiki/ 4355.configuring-dcb-with-equallogic-sans.aspx Set the Data Center Bridging VLAN ID To set the DCB VLAN ID for the first time: 1. Click Group → Group Configuration. 2. Click the Advanced tab. 3. Enter the DCB VLAN ID in the VLAN ID field; it must be a value from 0 to 4095. This value must be the same as the VLAN ID configured in the switch for use by the iSCSI SAN. Values 0 and 1 are not recommended. NOTE: • The VLAN IDs on the switch must match the VLAN you specify on the group. The ports on the switch need to allow both the old VLAN (which usually implies a VLAN ID of 0 if none has been set) and the new VLAN ID or all VLANs (trunk mode) to enable the group to communicate with the switch. • All group members must be 10Gb arrays and be active. • You can also specify the DCB VLAN ID through the CLI using the grpparams dcb def-vlan-id command. See the Dell EqualLogic Group Manager CLI Reference Guide for more information. Change the Data Center Bridging VLAN ID If your group's DCB VLAN ID has been changed from the default value of 2, you must configure the group to use it. About Volumes 165
