FlexPod Solution Overview
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.

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 Solution Overview
FlexPod Program Benefits
Cisco and NetApp have thoroughly validated and verified the FlexPod solution architecture and its many

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.

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

FlexPod Design Details
This section provides an overview on the FlexPod design and also the topology differences between the
FlexPod model with clustered Data ONTAP and Data ONTAP in 7-mode.
System Overview
FlexPod is a best practice data center architecture that includes three components:
• Cisco Unified Computing System (Cisco UCS)
• Cisco Nexus switches
• NetApp Fabric-Attached Storage (FAS) systems
These components are connected and configured according to best practices of both Cisco and NetApp
and provide the ideal platform for running a variety of enterprise workloads with confidence. FlexPod
can scale up for greater performance and capacity (adding compute, network, or storage resources
individually as needed), or it can scale out for environments that need multiple consistent deployments
(rolling out additional FlexPod stacks). FlexPod delivers a baseline configuration and also has the
flexibility to be sized and optimized to accommodate many different use cases.
Typically, the more scalable and flexible a solution is, the more difficult it becomes to maintain a single
unified architecture capable of offering the same features and functionalities across each
implementation. This is one of the key benefits of FlexPod. Each of the component families shown in
Figure 1 (Cisco UCS, Cisco Nexus, and NetApp FAS) offers platform and resource options to scale the
infrastructure up or down, while supporting the same features and functionalities that are required under
the configuration and connectivity best practices of FlexPod.
FlexPod Design Details
Design Principles
FlexPod addresses the following design principles and architecture goals:
• Application Availability—Ensures that the services are accessible and ready to use.
• Scalability—Addresses increasing demands with appropriate resources.
• Flexibility—Provides new services or recovers resources without infrastructure modification
requirements.
• Manageability—Facilitates efficient infrastructure operations through open standards and APIs.
Note Performance and comprehensive security are key design criteria that were not directly addressed in this
project but have been addressed in other collateral, benchmarking and solution testing efforts. The
functionality and basic security elements were validated.
FlexPod - Distinct Uplink Design
Figure 2 details FlexPod distinct uplink design with clustered Data ONTAP. As the illustration shows,
the design is fully redundant in the compute, network, and storage layers. There is no single point of
failure from a device or traffic path perspective.

11
FlexPod Design Details
Figure 2 FlexPod Distinct Uplink Design with Clustered Data ONTAP
*The FAS22xx fully supports IP-based storage, but does not support FCoE.
FlexPod distinct uplink design is an end-to-end Ethernet transport solution supporting multiple LAN and
SAN protocols, most notably FCoE. The solution provides a unified 10GbE-enabled fabric, defined by
dedicated FCoE uplinks and dedicated Ethernet uplinks between the Cisco UCS Fabric Interconnects
and the Cisco Nexus switches, as well as converged connectivity between the NetApp storage devices
and the same multipurpose Cisco Nexus platforms.
The distinct uplink design does not employ a dedicated SAN switching environment and requires no
direct Fibre Channel connectivity. The Cisco Nexus 7000 Series Switches are configured in N-Port ID
Virtualization (NPIV) mode, providing storage services for the FCoE-based traffic traversing its fabric.
As illustrated, link aggregation technologies play an important role, providing improved aggregate
bandwidth and link resiliency across the solution stack. The NetApp storage controllers, Cisco Unified
Computing System, and Cisco Nexus 7000 platforms support active port channeling using 802.3ad
standard Link Aggregation Control Protocol (LACP). Port channeling is a link aggregation technique
offering link fault tolerance, and traffic distribution (load balancing) for improved aggregate bandwidth
across the member ports. In addition, the Cisco Nexus 7000 Series Switches feature virtual PortChannel
(vPC) capabilities. The vPC allows links that are physically connected to two different Cisco Nexus 7000
series devices to appear as a single “logical” port channel to a third device, essentially offering device
fault tolerance. The vPC addresses aggregate bandwidth, link, and device resiliency. The Cisco UCS
Fabric Interconnects and NetApp FAS controllers benefit from the Cisco Nexus vPC abstraction, gaining
link and device resiliency as well as full utilization of an non-blocking Ethernet fabric.

12
FlexPod Design Details
Note The Spanning Tree protocol does not actively block redundant physical links in a properly configured
vPC-enabled environment, so all ports should forward on the vPC member ports.
This dedicated uplink design leverages FCoE-capable NetApp FAS controllers. From a storage traffic
perspective, both standard LACP and Cisco vPC link aggregation technologies play an important role in
FlexPod distinct uplink design. Figure 2 shows the use of dedicated FCoE uplinks between the Cisco
UCS Fabric Interconnects and Cisco Nexus 7000 Unified Switches. The Cisco UCS Fabric Interconnects
operate in the N-Port Virtualization (NPV) mode, meaning the servers’ FC traffic is either manually or
automatically pinned to a specific FCoE uplink, in this case either of the two FCoE port channels are
pinned. The use of discrete FCoE port channels with distinct VSANs allows an organization to maintain
traditional SAN A/B fabric separation best practices, including separate zone databases. The vPC links
between the Cisco Nexus 7000 switches’ and NetApp storage controllers’ Unified Target Adapters
(UTAs) are utilized for the Ethernet traffic, and dedicated FCoE links between the systems maintain
SAN A/B fabric segregation.
Figure 2 shows the initial storage configuration of this solution, as a two-node HA pair with the NetApp
clustered Data ONTAP. An HA pair consists of like storage nodes such as FAS22xx, 32xx, or 62xx
Series. Scalability is achieved by adding storage capacity (disk/shelves) to an existing HA pair, or by
adding HA pairs into the cluster or storage domain. For SAN environments, the NetApp clustered Data
ONTAP offering allows up to three HA pairs that include six clustered nodes to form a single logical
entity and large resource pool of storage that can be easily managed, logically carved, and efficiently
consumed. For NAS environments, up to 24 nodes can be configured. In both the scenarios, the HA
interconnect allows each HA node pair to assume control of its partner’s storage (disk/shelves) directly.
The local physical high-availability storage failover capability does not extend beyond the HA pair.
Furthermore, a cluster of nodes does not have to include similar hardware. Rather, individual nodes in
an HA pair are configured alike, allowing customers to scale as needed, as they bring additional HA pairs
into the larger cluster.
Network failover is independent of the HA interconnect. Network failover of each node in the cluster is
supported by both the interconnect and switching fabric, permitting cluster, data and management
network interfaces to fail over to different nodes in the cluster, which extends beyond the HA pair.
Figure 3 shows FlexPod distinct uplink design with Data ONTAP operating in 7-Mode. Data ONTAP
operating in 7-Mode is NetApp’s traditional functional model. As depicted, the FAS devices are
configured in an HA pair delivering five nines availability. Scalability is achieved through the addition
of storage capacity (disk/shelves), as well as through additional controllers such as FAS2200, 3200, or
6200 Series. The controllers are only deployed in HA pairs, meaning more HA pairs can be added for
scalability, but each pair is managed separately.

FlexPod Design Details
Figure 3 FlexPod Distinct Uplink Design with Data ONTAP in 7-Mode
*The FAS22xx fully supports IP-based storage, but does not support FCoE.
Figure 4 shows the topology differences between FlexPod model with the clustered Data ONTAP or Data
ONTAP operating in 7-Mode. As shown in Figure 4, the Cisco UCS and Cisco Nexus components do
not require any modifications. These layers of the stack are essentially unaware of the storage
controllers’ mode of operation. The differences occur within the NetApp domain of FlexPod
configuration. Clustered Data ONTAP requires cluster interconnect switches to connect the storage
controllers (nodes) composing the cluster.
Note Data ONTAP 8.1.2 supports up to six nodes (three HA pairs) in a SAN cluster.

Figure 4 FlexPod Model Comparison
FlexPod Design Details
It is a fundamental design decision to leverage clustered Data ONTAP or 7-Mode, because these cannot
be run simultaneously on the same controller, and the choice will influence hardware requirements, the
logical construction of FlexPod stack, and ultimately the operational practices of the enterprise.
Organizations having the following requirements should consider adopting clustered Data ONTAP:
• Large to midsize enterprises that are seeking scalable, shared IT solutions for nondisruptive
operations
• New installations
• Existing clustered Data ONTAP 8.x and Data ONTAP GX organizations that are looking to upgrade
• Organizations deploying an enterprise content repository
Organizations with the following characteristics or needs might want to use the 7-Mode design:
• Existing Data ONTAP 7G and Data ONTAP 8.x 7-Mode customers who are looking to upgrade
• Midsize enterprises; customers who are primarily interested in the FAS2000 Series
• Customers who absolutely require SnapVault®, synchronous SnapMirror®, MetroCluster™,
SnapLock® software, IPv6, or Data ONTAP Edge
Note It is always advisable to seek counsel from experts. Consult your NetApp account team or partner for
further guidance.

Manager, via the Cisco Nexus 2232 Fabric Extender platform, the CIMC does not manage the server
anymore. Instead it is managed with the Cisco UCS Manager software. The server is managed using the
Cisco UCS Manager GUI or Cisco UCS Manager CLI. The Cisco Nexus 2232 Fabric Extender provides
data and control traffic support for the integrated C-Series servers.
Cisco Nexus 1000v
Cisco Nexus 1000V Series Switches provide a comprehensive and extensible architectural platform for
virtual machine (VM) and cloud networking. These switches are designed to accelerate server
virtualization and multitenant cloud deployments in a secure and operationally transparent manner.
Integrated into the VMware vSphere hypervisor, and fully compatible with VMware vCloud® Director,
the Cisco Nexus 1000V Series provides:
• Advanced virtual machine networking, based on Cisco NX-OS operating system and IEEE 802.1Q
switching technology
• Cisco vPath technology for efficient and optimized integration of virtual network services
• Virtual Extensible Local Area Network (VXLAN), supporting cloud networking
These capabilities help ensure that the virtual machine is a basic building block of the data center, with
full switching capabilities and a variety of Layer 4 through 7 services in both dedicated and multitenant
cloud environments. With the introduction of VXLAN on the Nexus 1000V Series, network isolation
among virtual machines can scale beyond traditional VLANs for cloud-scale networking.
The Cisco Nexus 1000V Series Switches are virtual machine access switches for the VMware vSphere
environments running the Cisco NX-OS operating system. Operating inside the VMware® ESX® or
ESXi™ hypervisors, the Cisco Nexus 1000V Series provides:

• Simplified operations—Eliminates the need for a separate, virtual networking infrastructure
• Improved network security—Contains VLAN proliferation
• Optimized network utilization—Reduces broadcast domains
• Enhanced application performance—Off loads virtual machine switching from host CPU to parent
switch Application Specific Integrated Circuits (ASICs)
Cisco VM-FEX is supported on VMware ESX hypervisors and fully supports workload mobility through
VMware vMotion.
The Cisco VM-FEX eliminates the virtual switch within the hypervisor by providing individual Virtual
Machines (VMs) virtual ports on the physical network switch. VM I/O is directly sent to the upstream
physical network switch that takes full responsibility for VM switching and policy enforcement. This
leads to consistent treatment for all network traffic, virtual or physical. The Cisco VM-FEX reduces the
number of network management points by an order of magnitude as the physical and the virtual
switching layers are consolidated into a single switching infrastructure.
The UCS VIC leverages VMware’s Direct Path I/O technology to significantly improve throughput and
latency of VM I/O. Direct Path allows direct assignment of Personal Computer interconnect express
(PCIe) devices to VMs. VM I/O bypasses the hypervisor layer and is placed directly on the PCIe device
associated with the VM. The Cisco VM-FEX unifies the virtual and physical networking infrastructure
by allowing a switch ASIC to perform switching in hardware, not on a software based virtual switch.
The Cisco VM-FEX is off loads the ESXi hypervisor, which may improve the performance of any hosted
VM applications.
NetApp FAS and Data ONTAP
NetApp solutions are user friendly, easy to manage, and quick to deploy and offer increased availability
while consuming fewer IT resources. This means that they dramatically lower the lifetime total cost of
ownership. Whereas others manage complexity, NetApp eliminates it. A NetApp solution includes
hardware in the form of controllers and disk storage and the NetApp Data ONTAP operating system.
NetApp offers the NetApp Unified Storage Architecture. The term “unified” refers to a family of storage
systems that simultaneously support Storage Area Network (SAN), Network Attached Storage (NAS),
and iSCSI across many operating environments such as VMware, Windows®, and UNIX®. This single
architecture provides access to data by using industry-standard protocols, including NFS, CIFS, iSCSI,
FCP, SCSI, FTP, and HTTP. Connectivity options include standard Ethernet (10/100/1000, or 10GbE)
and Fibre Channel (1, 2, 4, or 8Gb/sec). In addition, all systems can be configured with
high-performance Solid State Drives (SSDs) or Serial ATA (SAS) disks for primary storage applications,
low-cost SATA disks for secondary applications (backup, archive, and so on), or a mix of the different
disk types.
A storage system running Data ONTAP has a main unit, also known as the controller or storage engine,
which is the hardware device that receives and sends data. This unit detects and gathers information
about the hardware configuration, the storage system components, the operational status, hardware
failures, and other error conditions.
A storage system uses storage on disk shelves. The disk shelves are the containers or device carriers that
hold disks and associated hardware such as power supplies, connectivity interfaces, and cabling.
