Preface

 

Overview

Many data centers use network attached storage (NAS) for a variety of applications and work loads. As more data is stored on NAS, efficient network designs are under evaluation to minimize latency, maximum use of interswitch links between switches and to automate network configuration changes. For these reasons, Brocade’s VCS Fabric with Brocade VDX Switches are increasingly being deployed when new NAS arrays are added to the storage pool.

 

Purpose of This Document

The goal of this document is to validate Brocade VCS Fabric with the Hitachi HNAS 4060 NAS storage array. The testing includes test cases that demonstrate VCS Fabric feature support, high availability and resiliency and automatic network reconfiguration when links are added or removed. This document provides validation test results for typical use cases of NAS with Brocade’s VCS Fabric and Hitachi HNAS IP storage arrays.

 

Audience

The content in this document is written for a technical audience, including solution architects, system engineers, and technical development representatives.

 

Objectives

  1. Validate interoperability with redundant and non-redundant network topologies with Brocade VCS and Hitachi HNAS.
  1. Identify any unique configuration details necessary to establish end-to-end connectivity.
  1. Simulate real-world customer environment perturbations and validate end-to-end behavior and recovery.

 

Test Conclusions

1. Brocade VCS Fabric with Hitachi HNAS NAS arrays smoothly interoperate with both redundant and non-redundant configurations. No exceptions were noted.

 

2. The configuration procedures followed Brocade VCS Fabric and Hitachi HNAS standard documentation guides and found no issues with these procedures.

 

3. All simulated changes in network and storage (add, remove, fail over) resulted in expected behaviors and IO recovery.

Test Plan

 

Scope

Testing is performed with GA versions of Brocade’s Network Operating System (NOS) in a heterogeneous environment. Test beds will include Brocade switches configured in routed and non-routed fabric configurations.

 

Testing is centered on interoperability and optimal configuration. Performance is observed within the context of best practice fabric configuration; however absolute maximum benchmark reporting of storage performance is beyond the scope of this test.

 

Test Configuration

The diagram below shows the test topology. The storage array is connected to one Brocade VCS Fabric with multiple Windows and Red Hat server hosts to drive I/O. The diagram below shows the network topology.

Hitachi HNAS Configuration

 

Step 1. Physical Interface Configuration

Add physical ports (tg interfaces) to logical interfaces (ag interfaces). When selecting ports to add to an ag interface, be aware that you cannot select individual tg ports on a single node.  You select ALL tg ports across all clusters to add to one ag interface. This is to provide node redundancy.

 

Example: By adding tg1 to ag1, you are adding the physical port tg1 on EVERY node in the cluster to ag1. You cannot add node1-tg1 to ag1 and then add node2-tg1 to ag2 because node2-tg1 was already added to ag1.

1.2 Ethernet Storage – Advanced Functionality

 

1.2.1 Storage Device – Jumbo Frame/MTU Size Validation

 

Test Objective

Perform I/O validation testing while changing MTU size from minimum to maximum with reasonable increments. Include Jumbo frame sizes as well as maximum negotiated/supported between device and switch.

 

Test Configuration

The following changes are made to the DUT before conducting this test case.

 

Step 1. On Hitachi HNAS, reconfigure Advanced IP Configuration to increase MTU to 9014.

 

HDSHNASAdvancedIPConfiguration-ChangeMTUSize.jpg 

   HDS HNAS Advanced IP Configuration-Change MTU Size

 

Step 2. On Hitachi HNAS CLI, add an MTU setting for the 9.79.0.0/16 subnet:

 

< =========== >

Node-2:$ mtu add 9.79.0.0/16 -s 9014

Successfully added route.

Node-2:$ mtu

Destination                    Gateway                 MTU     Flags 

9.79.0.0/16                    0.0.0.0                    9014    M     

Node-2:$

< =========== >

 

Step 3.  For Red Hat hosts, add “MTU=9000” to /etc/sysconfig/network-scripts/ifcfg-bond0 and then execute ‘service network restart’.

 

< =========== >

[root@ilo65205 ~]# more /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

IPADDR=9.79.100.21

NETMASK=255.255.0.0

ONBOOT=yes

BOOTPROTO=none

MTU=9000

USERCTL=no

NM_CONTROLLED=no

BONDING_OPTS="mode=802.3ad miimon=100 downdelay=5000 updelay=5000"

< =========== >

 

Step 4. For Windows 2012 Server host, reconfigure individual NIC team members for increased MTU size.

1.2.3 Storage Device – w/Congested Fabric

 

Test Objective

Create network bottleneck through a single Ethernet Fabric ISL. Configure VDX switch for AUTONAS. Configure multiple ‘NAS to host’ data streams sufficient to saturate ISLs’ available bandwidth for 30 minutes.  Verify file I/O completes error-free. Add L3 FCoE and L2 Ethernet traffic to fill available bandwidth. File I/O compares are disabled.

 

Test Configuration

The following changes are made to the DUT before conducting this test case.

 

Step 1. Configure NAS auto-QoS on VDX as follows:

< =========== >

nas auto-qos

nas server-ip 9.79.30.1/32 vlan 979

< =========== >

 

Step 2. Because the Brocade VDX 6730 switch does not support NAS auto-QOS, move all host connections to CASTOR-VCS20-12 as shown in the diagram below.

Step 3. Add IXIA traffic generator connections to the VCS Fabric ports shown on the right.

Step 4. Reconfigure VDX as follows:
