  • Welcome and personal introductionBrocade is proud to be the Global Platinum sponsor for the Hitachi Information Forum 2010.This presentation is designed to provide an insightful view of the industry…along with a detailed outline of the Brocade vision, our innovative technologies to achieve that vision and our strategic partnership with Hitachi Data Systems to provide you the foundation your virtualized data center can stand on.
  • There is hardly a technical paper or presentation these days that doesn’t include one or all three of these concepts. And yet few people stop to think about where they are in the adoption cycle or even whether they will be widely embraced.Today, I’ll address virtualization and its enablement of the cloud as well as convergence and its enablement of network simplification from a customer perspective. While these terms are typically used interchangeably, they are often used to imply interrelationship when none exists. Allow me to explain, I’ll start with the most basic, Convergence….
  • Most data centers have two distinct types of networks. They have a storage network built for reliability, guaranteed data integrity, and non-blocking performance. And a data network whose characteristics include affordable performance and ubiquitous deployment.The industry calls the uniting of storage and data networks “Convergence”. Since we as an industry used the exact same term to describe the integration of voice and video applications onto the data network ten years ago, we refer to that as Convergence 1.0 and refer to network convergence as “Convergence 2.0” to distinguish between and draw parallels from these two technology evolutions.Many people rushed to deploy converged solutions ten years ago and ended up with first-generation Voice over IP (VoIP)solutions that were not ready for enterprise deployment. As this animation implies, many people believe that combining storage and data into a common architecture is a simple mapping. But learning from the mistakes of a decade ago, we must ask three questions:Why should I converge?Why wouldn’t I want to converge?And how many people are actually doing this today?
  • This picture should answer the question, “Why would I want to converge?”Typical bladed or multicore servers may have 8 network connections per single unit of rack space. These support storage, management, and clusters as well as secure and public LANs.The complexity of managing this profusion of cabling is unmanageable in most large-scale data centers. The solution demands fewer connections with higher bandwidth and more traffic isolation.
  • With converged network solutions, server connectivity can be accomplished with a single redundant pair, vastly reducing the complexity of connectivity at the server and top of rack.But challenges remain… Some network design issues merely move to the top of the rackData and storage traffic can be risky to combine (a well-designed storage architecture becomes even more crucial)Data center bridges, like the Brocade 8000 top-of-rack solution, need to be members of both the storage network and the data network. This requires specialized expertise for protocol design and extensive multivendor, MULTINETWORK testing.
  • …because the trend that is going at full speed today is virtualization… While it is starting with basic applications and largely limited to single data centers… The number of users accessing an organization’s applications, and the amount of information for the applications (and about them) is skyrocketing.As you could see from the server growth statistic, companies can no long simply throw hardware at the problem…They are using virtualization to make the most of their capacity and allocating unused CPU cycles to exactly the applications that are demanding the most bandwidth.Virtualization equals increased capacity, without growing capital expenses and operating expenses.
  • That should give you the big picture of who Brocade is, what our vision is, and where we fit into your IT infrastructure.Now, we’ll get into more details about how Brocade can help you transform your network into a strategic business asset.< note to speakers: lead into your summary and/or begin transitioning to your next slide segment here (typically a specific market segment or vision slide) >
  • DVVS – Data, Voice, Video, Virtualization, Storage
  • Key PointsEnabling virtualization capabilities, such as Virtual Machine (VM) mobility, requires VMs to migrate within a single Layer 2 network.Paths are designated through the network as active or standby using STP. While this provides an alternate path, only one path can be used at a time, which means that network bandwidth is not well utilized.Since one of the goals of server virtualization is to increase utilization of the physical server, increased utilization of network bandwidth should also be expected.To increase network utilization, Multiple Spanning Tree Protocol (MSTP) and similar protocols allow for separate spanning trees per VLAN. While this improves bandwidth utilization, the STP limit of one active path between switches remains. And, because traffic paths are manually configured with MSTP, complexity increases.Another challenge with STP is network behavior when links fail. When failures occur, the spanning tree needs to be redefined. This can take anywhere from five seconds with Rapid Spanning Tree (RSTP) up to several minutes with STP—and this convergence can vary unpredictably even with small topology changes.

  • Existing IT architectures are not appropriate for this new world of high-performance, low-energy, resilient, deterministic networking Networks MUST move to a cloud-optimized architecture in order to achieve the performance, scale and simplicity that next-generation networking demands.The SINGLE MOST CRITICAL component of a cloud-optimized infrastructure is the FABRIC. Unlike classic hierarchical architectures, in fabric-based networks every point is physically connected to every other point, enabling better availability, scalability and utilization:Resilient without being redundantLow latency while scaling massivelyIncreased bandwidth with multi-pathingInherently flat and efficient
  • Key PointsWhen data centers leverage virtualization, there are some added networking challenges that they did not have to deal with when applications were tied to physical servers.Since key virtualization technologies, like VM mobility, need to operate in a Layer 2 network, Layer 2 performance scalability and reliability becomes a major concern. Spanning Tree Protocol is used to prevent loops in a multi-path IP environment and has major limitations.There is also a lot of complexity in Ethernet networks today. There are many individual switches to manage and advanced protocols throughout all of the layers of the network.All of this creates management overhead and drives up operating expenses.
  • Key PointsData Center Bridging (DCB) gives Ethernet lossless capabilities.Storage traffic can be isolated on a priority, allowing that priority to be lossless.Also, priorities can be given a certain percentage of network bandwidth, ensuring different types of traffic do not effect each other.
  • Brocade’s strategy to help customers innovate in their data centers is to deliver fabric technology for both storage and Ethernet networking. Fundamental belief is that in order for data centers to accommodate the rigorous requirements of virtualization and cloud architectures, they must realize the benefits of fabric-based solutions. The remainder of my presentation on fibre channel storage fabrics and then will ask Doug Ingraham to provide you with an update on our vision, progress to-date and strategy for our continued leadership in Ethernet fabrics.
  • Data Center are Migrating to FabricsThe networks we’ve built over the past decade are deep, rigid, complex, expensive to run, hard to debug, messes. There are so many artificial boundaries in here – subnets, vlans, security zones – that nobody can move anything.To protect against a switch failure, we pair up switches in each layer. The switches mirror each other so that if one goes down, the other takes over. Unfortunately, it means that we have to buy a pair of switches everytime we only really need one.To get resilience between layers. We run multiple links and then … spanning tree kicks in and we shut one off.That means that we have exactly twice as much equipment to start with at every layer and they we shut off all of the standby links. The average data center has about 40% of the total ports shut off.These architectures are expensive to implement and run and are not optimized for modern applications.Fabrics eliminate these problems. They eliminate the redundant switches. They eliminate wasted links. There is no spanning tree. They are inherently resilient and multi-pathing. They are ideal for virtualization. Customers typically save 40-50% day one over traditional designs.
  • Brocade’s strategy to help customers innovate in their data centers is by delivering fabric technology for both storage and ethernet networking. We will talk about our progress on ethernet fabrics at Tech Day, but for this discussion I am going to focus on our innovation and product announcements in FC.The culmination of these trends is resulting of a deconstruction of the traditional hierarchical data center IT model. In order for data centers to be able to accommodate the rigorous requirements of virtualization and cloud computing, they must migrate to a Fabric-based solution. Unlike classic hierarchical architectures, fabric-based networks enable far greater reliability, scalability and utilization.Brocade is the leader in fabric technology and the only company delivering solutions today that demonstrate a real vision for the transition to cloud-optimized networking. Brocade has distinguished itself for the last 15 years as the leader in Fibre Channel. More recently it has also taken a pioneering leadership position in Ethernet Fabrics, porting a wealth of experience in building advanced SAN networks to creating Ethernet Fabrics that enable data center-like characteristics throughout the virtualized and cloud-optimized network. I am going to focus my comments on our continuing innovation in Fibre Channel fabrics and Doug will discuss our progress and significant momentum in our next-generation Ethernet fabrics.

  • Let’s start with the Brocade Ethernet Fabric, in a private cloud with five VDX switches. You can create a port profile on any switch in the fabric.  When you do, the profile is automatically shared throughout the fabric. In essence, the cloud has become a big virtual switch.  Now, we’re going to bring up a new webserver, a virtual machine with the MAC address of 0000.0000.0000.0000. You will see that the “WebServer” port profile has been applied to this new VM. In this table, MAC address has also been propagated to all switches in the fabric so they all know what port that VM currently resides on.  I will show you that it has access to the applicable VLANs and devices in this VLAN. I can ping devices in my VLAN and Now we’re going to show VM migration. We’re going to spin off three more virtual machines.
  • And we’re going to connect that VM system to another switch. Because the MAC address is already approved, its presence is accepted within the fabric.  
  • At Brocade, we’re focused on what the network must do to support VM mobility over distance. Implementing a fully operational vMotion solution that spans data centers has requirements in three major areas: - Data synchronization between data centers to ensure applications always have access to that data, regardless of their location- A network infrastructure that provides high throughput with low latency, data security and layer 2 extension capabilities to enable workload mobility across networks Dynamic routing of client requests to the appropriate data center and server as applications move.Lastly, it’s fair to recognize that applications often have interdependencies on other elements of the data center, some of them stateful. Those elements either need to move with the application or be resident in data centers to which an application may move.
  • Well, clearly my video team got a little carried away with their green screen technology. Candidly, our challenge was to show a demo that is, in fact, quite boring as a result of its dramatic simplicity. <click> We simply moved a workload between our San Jose and Las Vegas data centers and made sure all existing and new client connections followed the application, without interrruption.But there is plenty of important technology behind this demo. I’d like to spend a few minutes talking through the components of the architecture.
