9 Preface Overview... 9 Purpose of This Document...9 Audience... 9 Objectives Test Conclusions...10 Related Documents...10 Document History...10 About Brocade About EMC...11 Overview Many data centers use iscsi block storage for a variety of applications and workloads. As more data is stored on iscsi, efficient network designs are under evaluation to minimize latency, maximize use of interswitch links between switches and to automate IP network configuration changes. For these reasons, Brocade s VCS Fabric with Brocade VDX Switches is increasingly being deployed when new iscsi storage arrays are added to the storage pool. Purpose of This Document The goal of this document is to validate Brocade VCS Fabric with the EMC VNX5300. 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 iscsi with Brocade s VCS Fabric and EMC VNX5300 iscsi storage arrays. Audience The content in this document is written for a technical audience, including solution architects, system engineers, and technical development representatives.

10 Objectives Objectives 1. Validate interoperability with redundant and non-redundant network topologies with Brocade VCS and EMC VNX Identify any unique configuration details necessary to establish end-to-end connectivity. 3. Simulate real-world customer environment perturbations and validate end-to-end behavior and recovery. Test Conclusions 1. Brocade VCS Fabric and EMC VNX5300 iscsi array smoothly interoperate with both redundant and non-redundant configurations. No exceptions were noted. 2. The configuration procedures followed Brocade VCS Fabric and EMC VNX5300 standard documentation guides and found no issues with these procedures. 3. All simulated changes in network and storage (add, remove, failover) resulted in expected behaviors and I/O recovery.

12 Test Plan Test Plan Scope...12 Test Configuration...13 DUT Descriptions...14 DUT Specifications...15 DUT Configuration Medusa I/O Generation Configuration The storage array is connected to one VDX Ethernet fabric with multiple server hosts to drive I/O. Scope Testing will be performed with 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. 12 Brocade VCS Fabric Technology with the EMC VNX5300 Test Report

13 Test Configuration Test Configuration FIGURE 1 Test Topology The following diagram shows VCS Fabric switch port connections and vlag (port-channel) ports for each server and the NetApp 3170 array.
