VMware vSphere 5.1 on FlexPod with Nexus 7000

Using FCoE

Goal of This Document

Cisco® Validated Designs include systems and solutions that are designed, tested, and documented to

facilitate and improve customer deployments. These designs incorporate a wide range of technologies

and products into a portfolio of solutions that have been developed to address the business needs of our

customers.

This document describes the Cisco and NetApp® FlexPod® solution, which is a validated approach for

deploying Cisco and NetApp technologies as a shared cloud infrastructure.

Audience

The intended audience of this document includes, but is not limited to, sales engineers, field consultants,

professional services, IT managers, partner engineering, and customers who want to take advantage of

an infrastructure built to deliver IT efficiency and enable IT innovation.

Changes in FlexPod

The following design elements distinguish this version of FlexPod from previous models:

•Introduction of the Cisco Nexus® 7000 product family, providing the highest level of availability.

•End-to-end Fibre Channel over Ethernet (FCoE) delivering a unified Ethernet fabric.

•Single wire Cisco Unified Computing System™ Manager (Cisco UCS™ Manager) management for

C-Series M3 servers with the VIC 1225 effectively doubling the server density per I/O module while

reducing cabling cost.

•NetApp clustered Data ONTAP® delivering unified scale-out storage.

FlexPod Solution Overview

Industry trends indicate a vast data center transformation toward shared infrastructure and cloud

computing. Enterprise customers are moving away from isolated centers of IT operation toward more

cost-effective virtualized environments.

The objective of the move toward virtualization, and eventually to cloud computing, is to increase agility

and reduce costs.

Especially because companies must address resistance to change in both their organizational and

technical IT models, achieving this transformation can seem daunting and complex. To accelerate the

process and simplify the evolution to a shared cloud infrastructure, Cisco and NetApp have developed a

solution called VMware vSphere® on FlexPod.

FlexPod® is a predesigned, best practice data center architecture that is built on the Cisco UCS, the

Cisco Nexus® family of switches, and NetApp Fabric Attached storage (FAS) or V-Series systems.

FlexPod is a suitable platform for running a variety of virtualization hypervisors as well as bare metal

operating systems and enterprise workloads. FlexPod delivers a baseline configuration and also has the

flexibility to be sized and optimized to accommodate many different use cases and requirements.

Figure 1 shows the components used in this solution, while also highlighting the inherent flexibility of

FlexPod.

This document describes VMware vSphere 5.1 built on the FlexPod model from Cisco and NetApp and

discusses design choices and deployment of best practices using this shared infrastructure platform.

FlexPod Solution Overview

Customer Challenges

As customers transition toward shared infrastructure or cloud computing, they face a number of

questions, such as:

•How do I start the transition?

•What will my return on investment be?

•How do I build a future-proof infrastructure?

•How do I cost-effectively transition from my current infrastructure?

•Will my applications run properly in a shared infrastructure?

•How do I manage the infrastructure?

The FlexPod architecture is designed to help you answer these questions by providing proven guidance

and measurable value. By introducing standardization, FlexPod helps customers mitigate the risk and

uncertainty involved in planning, designing, and implementing a new data center infrastructure. The

result is a more predictive and adaptable architecture capable of meeting and exceeding customers’ IT

demands.

FlexPod Program Benefits

Cisco and NetApp have thoroughly validated and verified the FlexPod solution architecture and its many

use cases while creating a portfolio of detailed documentation, information, and references to assist

customers in transforming their data centers to this shared infrastructure model. This portfolio includes,

but is not limited to the following items:

•Best practice architectural design

•Workload sizing and scaling guidance

•Implementation and deployment instructions

•Technical specifications (rules for what is, and what is not, a FlexPod configuration)

•Frequently asked questions (FAQs)

•Cisco Validated Designs (CVDs) and NetApp Validated Architectures (NVAs) focused on a variety

of use cases

Cisco and NetApp have also built an experienced support team focused on FlexPod solutions, from

customer account and technical sales representatives to professional services and technical support

engineers. The support alliance provided by NetApp and Cisco provides customers and channel services

partners with direct access to technical experts who collaborate with multiple Vendors and have access

to shared lab resources to resolve potential issues.

FlexPod supports tight integration with virtualized and cloud infrastructures, making it the logical

choice for long-term investment. The following IT initiatives are addressed by the FlexPod solution.

Integrated System

FlexPod is a prevalidated infrastructure that brings together computing, storage, and network to simplify,

accelerate, and minimize the risk associated with data center builds and application rollouts. These

integrated systems provide a standardized approach in the data center supports staff expertise,

application onboarding, and automation, as well as operational efficiencies that are important for

compliance and certification.

FlexPod Solution Overview

Fabric Infrastructure Resilience

FlexPod is a highly available and scalable infrastructure that IT can evolve over time to support multiple

physical and virtual application workloads. FlexPod has no single point of failure at any level, from the

server through the network, to the storage. The fabric is fully redundant and scalable and provides

seamless traffic failover should any individual component fail at the physical or virtual layer.

Fabric Convergence

FlexPod components are interconnected through the Cisco Unified Fabric network architecture, which

supports both traditional LAN traffic and all types of storage traffic, including the lossless requirements

for block-level storage transport over FC or FCoE. The Cisco Unified Fabric creates high-performance,

low-latency, and highly available networks, serving a diverse set of data center needs.

FlexPod uses the Cisco Unified Fabric to offer a wire-once environment that accelerates application

deployment. Cisco Unified Fabric also offers the efficiencies associated with infrastructure

consolidation, including:

•Cost savings from the reduction in switches (LAN/SAN switch ports), associated cabling, rack

space, all of which reduce capital expenditures (capex)

•Cost savings on power and cooling, which reduce operating expenses (opex)

•Migration to the faster 10 Gigabit Ethernet network, and in the future, to 40 Gigabit Ethernet and

100 Gigabit Ethernet

•Evolution to a converged network with little disruption to operations

•FlexPod with Cisco Unified Fabric helps you preserve investments in existing infrastructure,

management tools, and staff training and expertise

•Simplified cabling, provisioning, and network maintenance to improve productivity and operational

models

Network Virtualization

FlexPod delivers the capability to securely connect virtual machines into the network. This solution

allows network policies and services to be uniformly applied within the integrated compute stack using

technologies such as virtual LANs (VLANs), Quality of Service (QoS), and the Cisco Nexus 1000v

virtual distributed switch. This capability enables the full utilization of FlexPod while maintaining

consistent application and security policy enforcement across the stack even with workload mobility.

FlexPod provides a uniform approach to IT architecture, offering a well-characterized and documented

shared pool of resources for application workloads. FlexPod delivers operational efficiency and

consistency with the versatility to meet a variety of SLAs and IT initiatives, including:

•Application rollouts or application migrations

•Business continuity/disaster recovery

•Desktop virtualization

•Cloud delivery models (public, private, hybrid) and service models (IaaS, PaaS, SaaS)

•Asset consolidation and virtualization
