Large-scale server virtualization is generating unpredictable bandwidth requirements driven by virtual machine (VM) mobility. The move toward cloud computing is demanding a high-performance network interconnect that can be driven by servers and VMs that number in the tens of thousands. Modern virtualized multi-tiered applications are generating massive levels of east/west inter-server traffic. Unfortunately, traditional network topologies and solutions were not designed to support these highly virtualized environments with mobile VMs and demanding modern workloads. Ethernet fabrics have emerged as an attractive solution to these challenges, bringing dramatic improvements over the inefficiencies, rigidity, fragility, and management challenges of classic hierarchical Ethernet networks. At the same time, few organizations can afford to simply replace their data center network infrastructure all at once. Many organizations have found that key opportunities exist for introducing fabric technology into traditional network environments. •Scaling the network. The elasticity, manageability, flexibility, and scalability of Ethernet fabrics make them ideal for new virtualization and cloud computing environments. •Transitioning from Gigabit Ethernet (GbE) to 10 GbE. Many organizations are consolidating multiple workloads onto fewer more powerful servers, creating a demand for greater network bandwidth. •Adding Ethernet-based storage. Storage virtualization and those organizations developing Ethernet Storage Area Networks (SANs) require a true lossless fabric. •Adopting Software-Defined Networking (SDN). SDN can take various forms, but all of them introduce additional parameters to set up and manage, and they all typically require new skill sets as well. Ethernet fabrics provide a simpler, highly resilient, low-latency foundation for SDN deployments of all types. Brocade® VCS® Fabric technology, delivered by the Brocade VDX® family of switches, is ideal for these scenarios, enabling organizations to migrate to a highly automated, fabric-based design at their own pace, without disrupting their existing data center network architecture. Organizations can start as small as a two-node Brocade VCS fabric, piloting either at the traditional access or aggregation layer, and expanding seamlessly as needs dictate. Brocade delivers the required IT agility through automated, zero-touch VM discovery, configuration, and mobility, which is demanded by today’s constantly evolving workloads. This paper describes a number of criteria for selecting Brocade VDX switches, as well as scenarios for integrating Brocade VCS fabrics into existing hierarchical infrastructures. BROCADE VCS FABRICS AND VDX SWITCHES Brocade VCS fabrics provide advanced Ethernet fabric technology, eliminating many of the drawbacks of classic Ethernet networks in the data center. In addition to standard Ethernet fabric benefits, such as logically flat networks without the need for Spanning Tree Protocol (STP), Brocade VCS Fabric technology also brings advanced automation with logically centralized management. Brocade VCS Fabric technology includes unique services that are ideal for simplifying traffic in a cloud data center, such as scalable network multitenancy capabilities, automated VM connectivity and overlay visibility, and highly-efficient multipathing at Layers 1–3 with multiple Layer 3 gateways. The VCS architecture conforms to the Brocade strategy of “revolution through evolution,” so Brocade VDX switches with Brocade VCS Fabric technology can also connect to existing data center Ethernet products, whether offered by Brocade or other vendors. At the same time, this powerful technology enables new ways of working. For example, Brocade VDX switches are hardware-enabled to support emerging SDN protocols, such as Virtual Extensive LAN (VXLAN). Logical Chassis technology and northbound Application Programming Interfaces (APIs) can provide operationally scalable management and access to emerging management frameworks such as OpenStack. Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 3 of 14 DATA CENTER DESIGN GUIDE Scalable Brocade VCS Fabrics Brocade VCS fabrics offer dramatic improvements over the inefficiencies, inherent limitations, and management challenges of classic hierarchical Ethernet networks. Implemented on Brocade VDX switches, Brocade VCS fabrics drastically simplify the deployment and management of scale-out architectures. •Brocade VCS fabrics are elastic, self-forming, and self-healing, allowing administrators to concentrate on service delivery and not fabric administration. All-active connections and load balancing throughout Layers 1–3 provide resilience that is not artificially hampered by arbitrary limitations at any network layer. The distributed control plane ensures that all nodes are aware of the health and state of their peers and that they route traffic accordingly. Nodes can be added and removed non-disruptively, automatically inheriting predefined configurations and forming new links upon entry or removal of a node. •Brocade VCS fabrics are isotropic, offering uniform, multidimensional scalability that enables the broadest diversity of deployment scenarios and operational flexibility. Large or small, Brocade VCS fabrics work and act the same, offering operational efficiencies that span a very wide range of deployed configurations and requirements. •Brocade VCS fabrics are easy to manage, with a shared control plane and unified management plane that allow the fabric nodes to function and to be managed as a single entity, regardless of fabric size. Open APIs and OpenStack support facilitate orchestration of VCS fabrics within The On-Demand Data Center™. Brocade VCS fabrics offer considerable scale and capacity, as shown in Table 1. Table 1.

Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches Brocade VDX Switches Discussed in This Guide Brocade VDX 6710 Switch The Brocade VDX 6710 offers 48 fixed Gigabit Ethernet RJ45 ports and six 1/10 GbE Small Form-Factor Pluggable Plus (SFP+) ports in a single rack unit (1U). Brocade VDX 6720 Switch Available in both 1U and 2U versions, the Brocade VDX 6720 provides either 24 (1U) or 60 (2U) 1/10 GbE SFP+ ports, which can be acquired with the flexible and innovative Brocade Ports on Demand (PoD) licensing. Brocade VDX 6730 Switch The Brocade VDX 6730 adds Fibre Channel (FC) support, with the 1U version offering 24 1/10 GbE SFP+ ports and eight 8 gigabit-per-second (Gbps) FC ports, and the 2U version offering 60 1/10 GbE SFP+ ports and sixteen 8 Gbps FC ports. The Brocade VDX 6730 also supports PoD licensing. Brocade VDX 6740 Switch The Brocade VDX 6740 offers 48 10 GbE SFP+ ports and four 40 GbE Quad SFP+ (QSFP+) ports in a 1U form factor. Each 40 GbE SFP+ port can be broken out into four independent 10 GbE SFP+ ports, providing an additional 16 10 GbE SFP+ ports, which can be licensed with Ports on Demand. Brocade VDX 8770 Switch Available in 4-slot and 8-slot versions, the 100 Gb-ready Brocade VDX 8770 dramatically increases the scale that can be achieved in Brocade VCS fabrics, with 10 and 40 Gigabit Ethernet wire-speed switching, numerous line card options, and the ability to connect over 8,000 server ports in a single switching domain. 4 of 14 DATA CENTER DESIGN GUIDE A Choice of Brocade VDX Switches Given a range of switch options, organizations need to select a particular fabric topology that suits their own specific needs. Established cabling and cooling practices are factors in this decision. Some data centers are committed to top-of-rack switching models, while others prefer end-of-row. Application needs and administrative boundaries may also influence how Ethernet fabrics are introduced and deployed. Brocade VCS fabrics offer a choice of both fixed-port and modular switches that can be used together in virtually any configuration, and easily accommodate a broad range of deployments. Organizations also need the ability to adopt Ethernet fabric technology on their own terms, starting small and growing as needed. With a range of VCS-capable Brocade VDX switches supporting any type of topology, organizations can deploy exactly the type of VCS fabric that suits their application needs, expanding their deployments as needs dictate. The best fabric is of little use if it cannot be sized and optimized to meet the needs of the organization. Fabrics need to be able to scale linearly to support deployments, starting with a few ports and growing to configurations with thousands of ports. With the Brocade VDX switch family, organizations can predictably and seamlessly grow their VCS fabrics based on their specific needs and budgets. Figure 1 illustrates the linear scalability of Brocade VCS fabrics, while Table 2 defines port ranges and recommended switch configurations for small, medium, and large VCS fabric deployments, using both fixed and modular Brocade VDX switches.

A single larger domain affords a simple, highly efficient configuration that avoids STP while smoothly supporting significant east-west traffic common to modern applications. Data Center Bridging (DCB) is supported on all nodes, allowing for unified storage access over Ethernet. Multiple Brocade VCS domains can be configured to easily scale out the data center, while offering multiple active Layer 3 gateways, contained failure domains, and MAC address scalability—all while avoiding STP.

Brocade VCS fabrics easily accommodate a wide range of configurations, from a single large VCS domain to multiple smaller domains. Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 6 of 14 DATA CENTER DESIGN GUIDE Other than greenfield deployments, Brocade understands that few organizations have the luxury to perform large-scale replacements of their network infrastructure. As shown in Figure 3, organizations can easily deploy Brocade VCS fabrics at the access layer, incrementally expanding the fabric over time. As the Brocade VCS fabric expands, existing network infrastructure can remain in place, if desired. Eventually, the advantages of VCS fabrics can extend to the aggregation layer, delivering the benefits of Brocade VCS Fabric technology to the entire enterprise, while allowing legacy aggregation switches to be redeployed elsewhere. Alternatively, a VCS fabric can be implemented initially in the aggregation tier, leaving existing access tier switches in place.

Organizations can introduce Brocade VCS fabrics easily at the access layer, expanding seamlessly to the aggregation layer to bring fabric advantages to the entire enterprise, without impacting existing network infrastructure. SWITCH CONSIDERATIONS Switch choices are typically part of larger application design discussions and must take into account preferred topology choices and existing infrastructure. While actual fabric design is beyond the scope of this document, it is worthwhile to consider the role of fabric technology for different kinds of applications. Not all modern applications fit the classic multi-tiered application model, and approaches certainly differ for providing network infrastructure to different application tiers. At the same time, this familiar model can be useful for understanding switch choices and considering the advantages of one switch model over another. For a given situation, switch considerations are affected by various factors, including performance, wiring technology, scale, and cost. Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 7 of 14 DATA CENTER DESIGN GUIDE Table 3 lists key considerations for providing fabric infrastructure at the various tiers, as described in the sections that follow. Table 3. Switch Considerations for Multi-Tier Fabric Deployments Tier Key Considerations Storage/Media Typical Brocade VDX Switches Web tier Cost and density Network File System (NFS) storage/copper media 24-port Brocade VDX 6720 (10 GbE) or Brocade VDX 6740 48-port Brocade VDX 6710 (1/10 GbE) Application tier Database tier Uptime and resiliency for switching and storage Highly performance sensitive; uptime critical FC, Internet Small Computer Systems Interface (iSCSI) of Fibre Channel over Ethernet (FCoE), or NFS/optical media more common Brocade VDX 6720 (24-port or 60-port) or Brocade VDX 6740 FC/optical media Brocade VDX 8770 to connect to application and web tiers Brocade VDX 6730 (if FC is a requirement) Brocade VDX 8770 Brocade VDX 6730 to connect to existing SAN switches Web tier. For most organizations, the Web tier is typically stateless, and cost is usually a primary consideration over performance. Scale, density, and modularity are generally key. Most organizations provide web-tier infrastructure that is logically separate—if not physically separate—from the rest of the enterprise, for security and other reasons. Fixed-port switches are typical at the Web tier, due to their low cost per port and their compatibility with traditional web-tier server deployment models that allow for horizontal replication to achieve availability. Application tier. At the application tier, performance and cost are often roughly equivalent considerations. Network infrastructure may be separate from the web tier, or the two tiers may share infrastructure with VLAN separation. I/O requirements at the application tier are often dictated by the application vendor. Depending on the application requirements, performance and resiliency may be important considerations. Either fixed-port or modular switches can be deployed at the application tier, depending on the latency needs of the application. Database tier. Because it has the potential to affect the largest number of applications and users, the database tier is the most performance-sensitive. Reliability and uptime are likewise critical, demanding redundancy in both server and switching infrastructure. For these reasons, redundant modular chassis switches such as the Brocade VDX 8770 are typical at the database tier. These switches are paired with the Brocade VDX 6730 in some topologies, as FC I/O is a common requirement. BROCADE VDX AND 3RD PARTY SWITCH COMPATIBILITY The Brocade VDX family of products has been extensively tested with the Cisco Nexus and Catalyst family of products, among others, focusing on standards-based interoperability of the product lines. This includes testing of all Brocade VDX switches, including the embedded switches carried by our partners. This testing is ongoing with each new NOS release to ensure continuing compatibility of the Brocade VDX and Cisco Nexus and Catalyst product lines. Further we are committed to supporting interoperability with all standards-based products to ensure that our customers have the freedom of choice to choose the best-of-breed for their network and not be locked into a single vendor solution. Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 8 of 14 DATA CENTER DESIGN GUIDE EXAMPLE BROCADE VCS FABRIC TOPOLOGIES Ultimately, good fabric design is a combination of both switch and topology choices, weighed against application requirements and existing network infrastructure. The sections that follow describe several topology examples, in order to demonstrate the various ways that Brocade VDX switches can be used to build Brocade VCS fabrics that serve specific application needs or fit into an existing network infrastructure. Other topologies may be desirable, depending on application or infrastructure requirements. Homogeneous Fixed-Port Switch Design In some situations, it may be desirable to construct a Brocade VCS fabric entirely from fixed-port Brocade VDX switches. This approach provides numerous benefits, including a low cost-per-port and easy-scaleout ToR switching to correspond with racks of commodity servers. Applications for this topology approach might include High-Performance Computing (HPC), parallel computing, and Big Data applications. As shown in Figure 4, a homogeneous fixed-port design can provide redundant Brocade VDX 6700 Series leaf switches at the top of each rack, which are connected to additional redundant Brocade VDX 6700 Series switches (such as the Brocade VDX 6740 with 40 GbE uplinks) at the spine. This type of configuration can provide Gigabit and/or 10 GbE to servers in the racks. If block-level network storage is required, the configuration can provide 10 GbE DCB connectivity for either FCoE or iSCSI. Brocade VDX 6710 switches provide for Gigabit Ethernet connectivity and complement the 10 GbE support of Brocade VDX 6720 amd VDX 6740 switches. Bridging to existing FC SANs is also possible using the Brocade VDX 6730 (not shown). Brocade MLX Series Brocade VCS Fabric Core LAG Servers with 1 Gbps, 10 Gbps, and DCB connectivity 10 Gbps DCB FCoE/iSCSI Storage 1 GbE 10 GbE 40 GbE Figure 4. Fixed-port Brocade VDX 6700 series switches can be used to build a homogeneous Brocade VCS fabric. Homogeneous Modular Chassis Switch Design For large scale-out Ethernet fabrics, a homogeneous fabric built from Brocade VDX 8770 switches may represent an ideal solution, providing significant advantages at both the access and aggregation layers. Homogeneous fabrics based on the Brocade VDX 8770 maintain the large scale enabled by the switch, and enjoy a very low and consistent ~4 µsec port-to-port latency. Applications for such a topology might include those where consistent latency is critical, including media serving, gaming, and high-frequency trading. As shown in Figure 5, the Brocade VDX 8770 can also be deployed as an access layer leaf switch in middle-ofrow or end-of-row configurations in a data center environment—connecting to other Brocade VDX 8770 switches at the spine over redundant 40 Gbps virtual Link Aggregation Groups (vLAGs). In this fashion, the Brocade VDX 8770 switch can be used to build a single large fabric with over 8,000 direct server connections.

A homogeneous Brocade VCS fabric can be built from modular Brocade VDX 8770 series switches for scale, redundancy, and consistent latency. Mixed Switch Fabric Design For dense server deployments and highly virtualized environments, multiple Brocade VDX switch types can be combined. For instance, a small and cost-effective Brocade VCS fabric can be piloted using the family of Brocade VDX 6700 products alone—and eventually scaled out, using the Brocade VDX 8770, as the fabric grows and the organization moves toward deploying larger and larger virtualized environments and cloud services. This approach retains the ability to contain Layer 3 traffic within the fabric and provides a scalable, resilient, and elastic Layer 2 domain. In the configuration shown in Figure 6, Brocade VDX 6710 switch links provide redundant Gigabit Ethernet access to servers, while Brocade VDX 6720 and VDX 6740 switches provide redundant 10 Gigabit Ethernet links. To scale the fabric, Brocade VDX 8770 switches can be deployed both at the spine and leaf layers. When used as a leaf switch, the Brocade VDX 8770 switch greatly expands the VCS fabric, providing high-volume connectivity for large numbers of servers, along with administrative simplicity through a single logical chassis. When used at the spine, the Brocade VDX 8770 can provide Layer 3 routing capabilities. Brocade MLX® Series Routers with Multi-Chassis Trunking (MCT) are shown at the core. Again, Layer 3 activity is contained within the VCS fabric, reducing overall network latency and improving Layer 3 functionality throughout. Using the spine switches to handle Layer 3 traffic also shields core switches from considerable routing traffic, enabling further network scale with existing core switches while enhancing application performance. Multiple active Layer 3 gateways provide high availability through an architecturally hierarchical, but logically flat, network.

The Brocade VDX 8770 switch can be added to existing small-to-medium-scale VCS fabrics at both the leaf and spine for additional scale while containing Layer 3 traffic. In other scenarios, particularly those that are data-intensive with very low-latency requirements, the Brocade VDX 8770 switch can be paired with Brocade VDX 6730 switches for connecting to FC arrays, as shown in Figure 7. This highly-redundant dual-fabric configuration offers the benefits of both Brocade VCS fabrics and FC fabrics.

Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 11 of 14 DATA CENTER DESIGN GUIDE Multi-fabric Designs The Brocade VDX 8770 can be used to accomplish phased data center deployments of VCS fabrics, or to accomplish truly massive scalability through multi-fabric Brocade VCS Fabric deployments. By deploying the Brocade VDX 8770 switch as a spine switch, multiple fabrics can be interconnected to provide additional scale and Layer 3 flexibility. Figure 8 illustrates separate fabrics built from Brocade VDX 6700 and 8770 switches. As shown, vLAGs connect the separate fabric domains using both 40 GbE connections and 10 GbE DCB connections for storage access.

Multifabric Brocade VCS deployments are easily accomplished to achieve flexibility and offer significant scalability. Deploying the Brocade VDX 8770 and VCS Fabrics at the Classic Aggregation Layer Many medium-to-large data centers are looking for opportunities to move toward cloud computing solutions, while realizing the benefits of Ethernet fabrics. Often these organizations need to improve the performance of their existing networks, but they also want to protect investments in existing networking technology. Even in traditional hierarchical deployment scenarios, the combination of the Brocade VDX 8770 switch and Brocade VCS Fabric technology can offer significant benefits in terms of future-proofing the network, advancing network convergence, and offering a migration path to 40 GbE, eventually, 100 GbE technologies. The Brocade VDX 8770 switch can provide many advantages, especially for those organizations that are tied to a tiered network architecture for now, but want to deploy a hybrid architecture for investment protection. Deploying a Brocade VCS fabric at the traditional aggregation layer can dramatically improve the performance of the existing network, while protecting both investments in existing infrastructure as well as new investments in Brocade VCS technology. Brocade VCS Fabric Design Guide: Selecting and Deploying Brocade VDX Switches 12 of 14 DATA CENTER DESIGN GUIDE As shown in Figure 9, this approach can provide significant Layer 2 scalability for the attached hierarchical network, while sheltering core switches from considerable Layer 3 routing traffic. As shown, a Brocade VDX 6700 series switch provides traditional (non-VCS) 10 GbE DCB connectivity at the access layer, allowing a VCS fabric to be implemented at a later time. Dual Brocade MLX series switches or similar third-party switches can be deployed at the core level. Advantages of deploying Brocade VCS Fabric technology at the traditional aggregation layer include: •Multiple Layer 3 gateways for redundancy and optimal load balancing •Standard Layer 2 and Layer 3 functionality •Wire-speed performance •High-density 10 GbE and 40 GbE •~4 µsec latency within the VCS fabric •Resiliency through high availability •Reduced demand on core switches for east-west traffic re Co s es c Ac n tio ga e r g Ag Brocade ICX (Cisco, etc.) Brocade VDX8770 Brocade MLX Series with Multi-Chassis Trunking (or third-party switch) rs r ve Se Brocade FCX (Cisco, etc.) LAG Blade Servers with 10 Gbps Switches/ Passthrough Modules Brocade VDX 6740 1 GbE 10 GbE 40 GbE Figure 9.
