IBM System Networking on Track
As we pass the one-year anniversary of IBM’s acquisition of BLADE Network Technologies, I am pleased to report that IBM System Networking is on track in our focus to deliver “Smarter Networking for Smarter Data Centers.” We have exceeded our business objectives across the past four quarters, delivered an enhanced and expanded portfolio of data center networking solutions, and are succeeding in our goal to bring intelligence and speed to the essential access, distribution and aggregation layers where server and storage systems are connected to the data center network.
Gartner’s recent report: “Competitive Landscape: Data Center Ethernet Switches, Worldwide, 2011 Update” validates our growing market impact. Gartner places IBM System Networking as the number-two vendor in the data center networking market that has grown to $6.1 billion and 22.5 million ports.
Gartner reports that users now recognize the need for a "significantly new type of Ethernet switch for their data centers. As more and more data centers are affected by trends like consolidation, virtualization and automation, this has given rise to a set of new problems that network managers have to address.” As a result, Gartner asserts that data center networking must address:
• Growing east-west network traffic
• Growing need for 10 Gigabit Ethernet switches at every layer of the data center network
• Redundant design at various levels of the network
• Flat topologies to bring down the number of hops and reduce network latency
• Effectively providing interconnects and network services like security authentication, load balancing/failover, virtual LAN (VLAN) administration and traffic shaping to virtual machines.
• Overcoming the topological, failover and scalability limits imposed by spanning tree protocol (STP)
• Low power consumption with front to rear airflow design.
IBM System Networking delivers across all these requirements, which is why we are playing a leadership role in the data center networking market. Clients who deploy Smarter Computing using IBM System Networking solutions realize improved economics, better network performance, lower latency, less complexity, greater energy efficiency and streamlined management. These advantages become paramount as clients deploy a new class of switches specifically designed for the data center in ever-growing numbers.
What Makes A Good Network Fabric?
As I wrote in my earlier blog post, the data center network is going through a major transformation to support server virtualization and cloud computing, convergence of data storage, application-to-application traffic and new high-performance applications. To address these needs, the data center network fabric, the system network architecture that interconnects server devices and storage devices in a data center environment, has become a critical lynchpin of data center architecture. I am frequently asked the question, “What makes a good network fabric?” The term “fabric” has nearly as many definitions and permutations as “cloud,” so I would like to suggest the top 10 attributes that a data center network fabric should possess.
- Open and Interoperable – Modern data center networking is best accomplished when it is standards-based, when multiple vendors equipment can co-exist and interoperate, and clients can choose between multiple vendors’ wares without paying a pricing penalty or needing to rip-and-replace to meet growth needs and implement next-generation approaches. Standards-based Ethernet is a fabric essential.
- High Speed – To meet the performance needs of big data, cloud computing and workload-optimized systems, data centers are increasingly implementing 10 Gigabit Ethernet on the server and in the access and aggregation layers, which is driving interest in 40 Gigabit Ethernet with 100 Gigabit Ethernet on the horizon.
- Low Latency - Applications such as high-frequency trading require the lowest possible latency. The race to zero latency is enabled by ultra-low-latency switches that deterministic with the same connection speeds across every port combination.
- Loss-less – To meet the needs of machine-to-machine applications and converged data and storage networking, Ethernet networks must be loss-less. Network equipment supports the Data Center Bridging (DCB) standards to ensure loss-less operation.
- Flat – Clos and fat tree network designs are becoming increasingly prevalent for the flow-based, non-blocking, shortest path network fabrics required in highly virtualized and cloud data centers and for converged data and storage traffic. With standards such as Transparent Interconnection of Lots of Links (TRILL) and Shortest Path Bridging (SPB) on the horizon and other alternatives for flat networks requiring proprietary implementations, network architects favor existing approaches to meshed networking such as Virtual Link Aggregation (vLAG) to maximize network efficiency, reduce congestion and address Spanning Tree limitations by creating active/active Layer 2 network paths for load balancing and redundancy.
- Virtualization Aware – To ensure that network security, performance and access policies move dynamically when live virtual machines migrate from server to server anywhere in the virtualized data center or private cloud, the Edge Virtual Bridging (EVB) 802.1Qbg standard specifies the interaction between virtual switching environments in a hypervisor and the first layer of the physical switching infrastructure. The EVB 802.1Qbg standard addresses the conventional vSwitch’s lack of network management, monitoring and security.
- Scalable – Linearly scalable is a requisite of network fabric design, which can be achieved by non-blocking, non-oversubscribed topologies implemented using top-of-rack switches.
- User Control – The emerging OpenFlow specification enables network infrastructure providers to deliver open virtual networking systems that that are easy for users to control, optimize performance dynamically and minimize complexity. OpenFlow-based networks enable the network administrator to easily configure and manage virtual networks that control traffic on a per-flow basis. The administrator can easily program an OpenFlow controller to create or delete multiple independent virtual networks and related policies that span the system network without having to deal with the complexities of the underlying physical network and protocol details.
- Unified Management – Network devices that make up the fabric should be managed, configured and provisioned as if they were a single logical device, including the ability to can track virtual machines by switch or IP address, and pre-provision network characteristics for VMs.
- Low Lifecycle Costs – And finally, per-switch costs should be affordable so networks can scale on an incremental basis, the need for expensive chassis switches should be minimized, and low power requirements and cooling efficiencies should enable low energy costs particularly for massive networks fabrics that interconnect thousands of server and storage systems.
We have designed IBM System Networking’s Unified Fabric Architecture, our fast, smart, interoperable and proven data center Ethernet network fabric, to deliver across all 10 of these attributes. Unified Fabric Architecture along with the ability to replicate pre-provisioned racks and integrated systems, enables clients that have already invested billions of dollars in their data centers to take advantage of the best innovations in the industry and achieve the lowest possible cost of ownership for their IT infrastructure.
New IBM System Networking Innovations Address CIOs’ Pain Points
As I meet with CIOs around the world, the key issues they are working to address are invariably similar. Across the board, they are seeking to implement data center solutions that enable scalability, density, simplicity of management and provisioning, IT efficiency and virtualization, enhanced security, big data and analytics and low lifecycle costs. IBM System Networking is introducing a range of innovative new products that address these requirements. With these new offerings, CIOs can:
Scale SAN fabrics for private clouds. IBM System Networking is delivering new, high-performance 16Gbps Fibre Channel storage area networking (SAN) backbone, switch and management solutions designed to help enterprise clients migrate smoothly to private cloud architectures through faster data transfers, fewer links needed to accomplish the same task and fewer devices managed overall, with energy consumption seven times more efficient than competitive solutions.
Increase density and flatten networks. The new IBM Rackswitch G8316 is IBM System Networking’s new 40 Gigabit Ethernet aggregation switch with 16x 40G ports to aggregate multiple racks of servers or 64x 10G ports using breakout cables and a powerful control plane for higher performance.

Networks Go Flat So Data Can Go Faster
Today’s application requirements place new demands on the data center network fabric to deliver non-stop, ultra-low latency traffic flows. This traffic is increasingly “east-west” in nature to enable server-to-server communications versus the “north-south” traffic that characterizes conventional client/server and Web-based application environments. In fact, today, as much as 80 to 85 per cent of the traffic in cloud and virtualized server infrastructures – moves from server to server.
Deployment of the network fabric to serve these “east-west” requirements ideally begins at the edge of the network, close to servers, applications, users and innovation. So, today’s evolving data center architectures start with building out the fabric at the edge, connecting multiple blade servers, racks or systems, and eventually connecting multiple data centers. This is all about allowing clients to take advantage of fabric technology without expecting them to undertake an expensive and resource intensive forklift upgrade. That’s why starting at the edge makes a lot of sense.
For the intensive machine-to-machine communications required for server virtualization, cloud computing and high performance computing applications such as high-frequency trading, latency should be as close as you can possibly get to zero. There is the basic latency associated with the speed of light and the transmission medium, so as close as you can possibly get to zero defines the ideal. People in the industry have used the term the race to zero latency as a way of describing this insatiable quest for driving latency out of the system.
Clients are deploying IT infrastructure on an unprecedented scale. For example, data centers that were deploying five to six thousand servers on an annualized basis are now are routinely looking at deploying an order of magnitude more server infrastructure. So the scale at which these clients are deploying server infrastructure and storage capacity is huge. And if the network fabric that is connecting these servers and storage devices does not scale along with servers and storage, then you’ve got a problem.
While on one hand, clients are staring down the barrel of deploying an order of magnitude more servers and storage infrastructure than they ever have before, on the other hand they’re also concerned about ineffectiveness as it relates to utilization of their IT infrastructure. A big focus for enterprises is to increase the utilization of their IT infrastructure. The airline industry calls this yield management. The hospitality industry calls this occupancy rates. In the context of the data center, this is all about maximizing the utilization of IT infrastructure.
We in IBM System Networking agree with The Register’s Timothy Prickett-Morgan who in an insightful article “No More Tiers for Flat Networks,” writes, “For companies that need network traffic to move more efficiently at higher bandwidth and with lower latencies, then a leaf-spine network that has a flatter architecture, or perhaps a fat tree network inspired by supercomputers or a Clos network inspired by telecommunications, might be just the ticket.”
The definition of an ideal fabric is one that does not require clients to jump through hoops, change out servers or add unnecessary complexity. A good fabric should be one that can provide connectivity for the client’s existing infrastructure. That’s why IBM is a big proponent of standards, because we fundamentally believe that standards can bring not only the most innovative solutions to marketplace, but also deliver solutions that don’t lock clients into a particular type of technology or a specific vendor.
The data center network is going through a major transformation to support server virtualization and cloud computing, convergence of data storage, server-to-server traffic and new high-performance applications. To address these needs, the data center network fabric, the system network architecture that interconnects server devices and storage devices in a data center environment, has become a critical lynchpin of data center architecture. And the move to flat networks is enabling the fabric to help data go faster. And for today’s requirements, faster is most definitely better.
Harnessing the Full Potential of Virtualization
With VMworld 2011 taking place this week in Las Vegas (August 29 to September 1), the industry’s attention is riveted on virtualization. IBM provides deep virtualization expertise and an integrated portfolio of solutions to enable and support business and IT virtualization objectives. IBM approaches transformation from a holistic perspective with smarter systems, software, and services, enabling virtualization not only at the platform level, but also across operating systems and middleware.
Virtualization brings both benefits and drawbacks to the data center: it can maximize underutilized resources and minimize infrastructure spending—but add complexity and administrative overhead for the network administrator.
Today, among the biggest problems clients are facing with their virtual server and storage infrastructures is that when VMs move, the network that connects these server and storage devices is not VM aware, relying instead on conventional physical device awareness. Thus, with a network that is not VM-aware, when VMs move, network addresses, security policies and class of service policies need to be re-configured manually. Enabling the network with awareness of virtualization is what is needed.
This inability of conventional data center networks to understand the language of virtualization and see Virtual Machines (VMs) as they move from server to server and even from data center to data center poses a major impediment to the use of virtualization, particularly for production application workloads, where performance, availability, and security are bottom-line priorities. Those who manage physical and virtual infrastructures know that the network must keep pace with virtualization, and they are increasingly vocal about their desire for scalable, secure and open solutions for building a virtualization-aware network.
To fulfill the promise of smarter computing, Virtual Machines (VMs) need to be supported by an intelligent network. IBM System Networking’s switch-resident VMready® with Virtual Vision is a unique solution that enables the network to be Virtual Machine aware, so that the network can be configured, managed and secured for 1000s of virtual ports (v-ports).
With VMready, as VMs migrate across physical hosts, so do their network attributes automatically, retaining the same ACLs, QoS and VLAN attributes. VMready will support the emerging Edge Virtual Bridging (EVB) technologies now being defined by the IEEE 802.1Qbg working group to make it easier for businesses to achieve server-network virtualization in the data center.
Our clients have been crystal clear in expressing their desire for networks that can scale, secure and migrate VMs even across long distances between data centers. And, they want to achieve this automated network change management without locking into proprietary stacks or having to rip and replace their existing virtual infrastructures. With VMready and Virtual Vision, IBM is enabling data center operators to maximize their investment in server virtualization.

IBM’s “Blue Pods”
With standardized components available for virtually every element of IT infrastructure from server to storage and network to rack, it’s perhaps no surprise that the standardized data center or “Pod” is becoming increasingly popular. For example, IBM’s Portable Modular Data Center is a data center in 20- or 40-foot shipping container that can be located anywhere that power and chilled water can be delivered. Other “Blue Pods” include the Enterprise Modular Data Center, a standardized raised-floor data center that can be built out in modules of 5,000 to 20,000 square feet, and the Modular High-Density Zone, which can convert an existing raised-floor space into an area that can deliver more computing capacity and power density.
As organizations struggle to handle growth in existing data centers, most organizations need to install and operate high-density computing to keep up with IT demands. However, the majority of today’s data centers are not designed to support high-density computing. So, these modular data centers offer a quick-to-deploy high-density solution with exceptional energy efficiency. And these modular approaches are ideal for organizations that want affordable capacity on demand. A Portable Modular Data Center can be designed, built and drop-shipped in as little as a few weeks to any location in the world, and does not require onerous capital outlays.
An IBM Portable Modular Data Center can cost up to 30 percent less to design and build compared to custom raised floor solutions, and can have up to a 50 percent smaller footprint. These Blue Pods are open, using industry-standard 19-inch racks and can house 1,428 blade servers or 1,178 IBM iDataPlex servers per container. This high-density compute power requires equivalent networking capacity. And this is where IBM System Networking is an ideal complement. IBM System Networking RackSwitch products consume power equivalent to standard light bulbs and are designed with server-friendly airflow that matches the hot-aisle/cold-aisle designs of the modular data center. IBM BladeCenter switches consume even less power and are tightly integrated with the BladeCenter architecture. Our VMready switch-resident software provides the networking capability to equip the Pod for the challenges of virtualization.
As CIOs remake IT infrastructures into more agile and automated environments that can respond to complexity with operational flexibility, Blue Pods support change while helping to mitigate associated risks. They help to address the continuing pressure to do more, faster and better – with less. In many cases, Pods enable organizations to accelerate their preparations for increasing complexity without requiring a significant expansion of existing IT operations. And Pods address the imperative to do more, faster and better—with less. Pods enable the data center to perform as the engine of business growth. And that’s what smarter computing is all about.

The Transformation of the Data Center Network
Recently, I joined the other networking industry executives in Network World’s Data Center Switching Challenge Series. Host Robin Layland points out that the data center network is undergoing a major transformation as server virtualization, intense storage growth and the increase in east-west traffic – application-to-application and application-to-storage traffic – are placing new demands on the data center networking infrastructure. Layland asserts that to accommodate these changes, data centers must become more cloud-like. That requires running a new Ethernet fabric – a high-throughput, self-configuring, low-latency and self-healing data center network that automatically forwards traffic over the shortest available path. I couldn’t agree more.
Certainly, new technology innovations including the transformation of the data center network, signal that we are entering a new era of computing that IBM calls Smarter Computing. At IBM System Networking, we believe that Smarter Computing can be achieved by connecting servers and storage with a high-speed and intelligent network fabric that is faster, greener, open and easy to manage. In Round One of the Challenge, I describe how evolving to these next-generation data centers, requires organizations to scale their infrastructures while minimizing complexity, achieving virtualization and consolidation with the quality of service required for production application workloads and successfully merging data and storage into a single network.
As organizations drive to transform and virtualize their IT infrastructures to reduce costs and manage risk, networking is pivotal to success. Optimizing network performance, availability, adaptability, security, and cost is essential to achieving the maximum benefit from the data center infrastructure. This in turn addresses CIOs’ key issues, including scalability, density, simplicity, utilization, security, analytics and total cost of ownership.
The value proposition for IBM System Networking is to provide the essential data and storage networking solutions under the IBM brand to connect servers to servers, servers to storage and storage to storage. Clients seeking more efficient data centers with the greatest business value and lowest total cost of ownership for their data center networks can implement an open, standards-based approach to simplify management, flatten and converge the network and optimize and automation virtualization.
In Round Two of the Challenge, Robin and I take a deeper look into the requirements for the data center network fabric in a brief podcast. The best way to look at the attributes of a data center fabric is what we call the four “L’s”. It’s got to be lossless. It’s got to be low latency. It’s got to consume low power and it’s got to have a very low cost of acquisition and operation. These are the essential attributes of a data center interconnect fabric. The problems on a large scale that this sort of a data center fabric is trying to solve are, first and foremost, to help clients scale their infrastructure. Second, to allow clients to increase the density of clients and storage per square foot of raised floor. Third, to make it incredibly simple to provision and manage data center infrastructure. Fourth, to enhance the security of the IT infrastructure. Fifth, to aid in the process of better analytics of a corporation’s information and data repositories. Sixth, to maximize the utilization of the IT infrastructure through technologies like virtualization, and finally, to lower the total cost of ownership of IT infrastructure.
Network World’s Data Center Switching Challenge is a great place to start when you are evaluating your data center networking needs and how leading vendors are taking new and innovative approaches to address next-generation requirements.

IBM System Networking RackSwitch G8264 Wins Communications Solutions Product of the Year Recognition
I am happy to report that the IBM System Networking RackSwitch G8264 is a recipient of TMC’s 2010 Communications Solutions Product of the Year Award. See the press release here.
The RackSwitch G8264 is IBM System Networking’s innovative 10/40 Gigabit Ethernet (GbE) switch specifically designed for the data center to provide speed, intelligence and interoperability, interconnecting highly virtualized servers equipped with 10 Gigabit Ethernet and providing seamless migration to 40 Gigabit upstream networks.
RackSwitch G8264’s is power packed with innovations that include:
Single-Chip Switch Fabric: RackSwitch G8264 uses an innovative switching architecture to operate with low, deterministic latency, consistent bi-directional throughput at line rate across all ports combinations, better microburst absorption, greater reliability and ultra-low power consumption of just 5.8 watts per port.
Massive Scale: RackSwitch G8264 includes 48 SFP+ ports for 10 GbE or 1 GbE operation and four QSFP+ ports for 40 GbE uplinks or 10 GbE use via a breakout cable for a total of 64 10 GbE ports. The terabit-class switch provides massive scalability for highly virtualized data center networks with up to 448 10GbE server ports in a stacked configuration for interconnecting thousands of virtual machines.
Virtual Vision: RackSwitch G8264 integrates VMready with Virtual Vision to secure and automate Virtual Machine migrations across large data center environments. Innovative and proven VMready “sees” virtual machines (VMs) as they move from server to server, protecting virtual machines by automatically synchronizing network policies among switches and hypervisors. With the Virtual Vision central policy database, VMready provides a single point of management for VM traffic and security across an entire data center with hundreds of servers and thousands of VMs, all designed for easy transition to emerging IEEE 802.1Qbg standards.
Next Generation Data Center Networking: RackSwitch G8264 supports the DCB/CEE standards for converged data center networks for FCoE, iSCSI or NAS, IBM Virtual Fabric for flexible vNIC connectivity, HotLinks and Layer 2 failover and standard Layer 2/3 features including stacking, IP PIM multicast, dynamic routing and spanning tree.
Congestion Prevention: Because network traffic between highly virtualized multi-core servers generates large amounts of server-to-server network traffic, virtualized servers need congestion notifications much earlier than enabled by conventional switches. IBM RackSwitch G8264 incorporates Explicit Congestion Notification (ECN) and Weighed Random Early Detection (WRED), which control packet flow from servers to avoid large saw-tooth fluctuations in network throughput that can slow application performance.
The IBM System Networking RackSwitch G8264 tops in top of rack switches, and this latest award is welcome recognition of the innovation that sets it apart.
