Overview

Brocade’s VCS Fabric is an innovation solution that removes the need for Spanning Tree Protocol providing 200% more bandwidth than typical STP designs. Network Attached Storage (NAS) is popular as it provides shared storage using TCP/IP typically over Ethernet.

 

What You Learn

This How To provides a procedure for configuring a Brocade VCS Fabric of Brocade VDX Switches when connecting it to a NetApp 3170 NAS filer and hosts with the QLogic 8152 CAN.

 

There has been some confusion about VCS Fabric support for this configuration. In particular, does the Brocade VCS Fabric FibreChannel over Ethernet (FCoE) license have to be installed? The short answer is “NO”.

Typical Topology

A typical topology is shown below.  The NAS storage is connected to a distribution layer switch so all access layer hosts can access and share its storage resources.

   VCS Fabric Leaf-Spine Topology with NAS

 

A Brocade VCS Fabric requires Brocade VDX Switches. Similar to the Fibre Channel world where a SAN fabric provides low, deterministic latency with all equal cost paths available for storate traffic, a VCS Fabric is ideal for NAS storage traffic as it too provides low, deterministic latency with all equal cost paths available. And, a VCS Fabric automatically reconfigures traffic flows whenever inter-switch links (ISL) change as well as automatically creating ISL Trunks when multiple ISL connections are plugged into two switches. A vLAG provides multipath support between servers and the leaf switches. Each link in the vLAG can terminate on a separate leaf switch so if one goes off-line, storage traffic continues to flow on the remaining link(s).

 

Procedure

The following outlines the procedure to configure a VCS Fabric when attaching a NetApp 3170 filer and the QLogic 8512 CNA in hosts running Windows Server 2012. The QLogic CNA is a 10 GE adaptor capable of supporting Converged Enhanced Ethernet (CEE).

Task 1: Configure VLAN for Storage Traffic

 

Step 1. Configure NetApp Filer

Configure the NetApp NAS server IP address in the same subnet used for the NetApp virtual interfaces.

 

Step 2. Configure Brocade VCS Fabric

Configure a VLAN interface and assign the VE interface to the same IP subnet used by the NetApp NAS server. For example, if the NetApp filer NAS traffic from server with IP address 192.168.200.104/32 use VLAN 50, the following command will create that VLAN in the VCS Fabric.

 

< ======= >

VDX6720-1(config-auto-qos)# nas server-ip 192.168.200.104/32 vlan 50

< ======= >

 

Task 2: Create Server Ports in VCS Fabric

 

Step 1. Create a Port Channel

Add a port channel (100) and assign the host ports to the port-channel.

 

< ======= >

interface Port-channel 100

 vlag ignore-split

 switchport

 switchport mode access

 switchport access vlan 50

 spanning-tree shutdown

 no shutdown

< ======= >

 

Step 2. Create NIC Teaming

Create NIC teaming with LACP mode on the VDX switch ports connected to the hosts.

 

< ======= >

interface TenGigabitEthernet 5/0/34

 no fabric isl enable

 no fabric trunk enable

 channel-group 100 mode active type standard

 lacp timeout long

 no shutdown

< ======= >

 

Task 3: Configure NAS Storage Ports in VCS Fabric

 

Step 1. Configure Port Channel

Define a port channel on the VDX Switch ports connected to the NetApp NAS and assign the ports to VLAN 50.

 

< ======= >

interface Port-channel 200

 vlag ignore-split

 switchport

 switchport mode access

 switchport access vlan 50

 spanning-tree shutdown

 no shutdown

< ======= >

 

Step 2. Configure Converged Enhanced Ethernet (CEE)

When using a CNA adaptor like the QLogic 8152, set the CEE to default for each VDX switch port in the port channel connecting to the NetApp NAS Filer. You can also configure “cee-default” under the portchannel configurations connecting to the NetAPP storage.

 

< ======= >

interface TenGigabitEthernet 5/0/18

 cee default

 no fabric isl enable

 no fabric trunk enable

 channel-group 200 mode active type standard

 lacp timeout long

 no shutdown

< ======= >

 

Task 4: Configure the NetApp 3170 Filer

 

Step 1. Create a Storage Volume

Go to Volumes and create a storage volume.

 

a. Login to the filer

< ======= >

 

b. Go to Volumes and Create a Volume

Step 2. Create a Path for Volume Access

Go to shares folder and create a path through which the newly created volume can be accessed for CIFS.

Step 3. Export the Path

Export the path under NFS Export for NFS shares for UNIX based systems. Make sure to edit the UNIX security  under Client Permisssion for Export by granting root access to all hosts.

Step 4. Configure NAS Array Port IP Address

Go To Networkà Network Interfaces. Then click on the interface that connects the NetApp port to the VCS Fabric and configure the appropriate IP address:

Step 5. Create a Virtual Interface

To create a Virtual interface with LACP LAG : create a VIF and add the 10G interfaces from the standalone cluster connecting to the VDX

Task 5: Configure Windows 2012 Server

Configuration a Windows 2012 Server for Ethernet teaming on the host ports that connect to the VCS Fabric switch(es). Choose LACP mode to get an ACTIVE-ACTIVE configuration
