IBM Delivers Standards-Based Virtualization Awareness and Automation for Large-Scale, Highly Virtualized Data Centers
With the vast majority of IT organizations now implementing virtualization, clients are seeking to dramatically reduce cost and complexity in highly virtualized data centers. In today’s data center environments, server virtualization is often managed separately from physical infrastructure, requiring the collaboration of server, network, storage, and security administrators. Data center managers are seeking a consistent networking environment across virtual and physical environments, so that virtual and physical servers can use the same configurations, policies and management tools. Network policies should migrate automatically along with mobile virtual machines to ensure that security, performance and access remains intact as virtual machines move from server to server.
To address the need for massively scalable, highly virtualized data centers, key standards have emerged for network virtualization automation. IBM System Networking
has developed and delivered the new IBM Distributed Virtual Switch (DVS) 5000V
™ alongside switch-resident IBM VMready®
, so clients can implement standards-based network virtualization in today’s I/O-intensive virtual switch environments. Using IBM’s innovative VMready virtualization-aware networking on IBM RackSwitch™
, as well as embedded Ethernet switches for IBM BladeCenter®
and IBM FlexSystems®
, along with IBM’s DVS 5000V as the virtual switch in VMware environments, clients can radically simplify and automate virtualization management. VMready works with all the major hypervisors and supports the IEEE 802.1Qbg standard for automating Virtual Machine mobility. VMware clients can further optimize and automate virtualization management with more advanced capabilities using the new IBM virtual switch.
The IBM System Networking Distributed Virtual Switch 5000V is an advanced, feature-rich distributed virtual switch developed by IBM in cooperation with VMware with policy-based virtual machine (VM) connectivity. The IBM Distributed Virtual Switch (DVS) 5000V enables network administrators familiar with IBM System Networking switches to manage the IBM DVS 5000V just like IBM physical switches using advanced networking, troubleshooting and management features so the virtual switch is no longer hidden and difficult to manage.
Support for Edge Virtual Bridging (EVB) based on the IEEE 802.1Qbg standard enables scalable, flexible management of networking configuration and policy requirements per VM and eliminates many of the networking challenges introduced with server virtualization. The IBM DVS 5000V works with VMware vSphere 5.0 and beyond and interoperates with any 802.1Qbg-compliant physical switch to enable switching of local VM traffic in the hypervisor or in the upstream physical switch. No fork lift of physical edge switches is required -- a simple firmware upgrade enables IEEE 802.1Qbg support on IBM physical switches. Virtual Machine (VM) traffic is switched at the device -- virtual or physical -- nearest to the VM in the traditional vSwitch EVB mode or in the transparent or reflective relay VEPA mode. IBM System Networking DVS 5000V is highly recommended for VM switching in VMware vSphere enterprise data center solutions – it is designed from the ground up to automate and scale any highly virtualized enterprise workload.
The standards-based network virtualization awareness, automation and “Virtual Vision” provided by IBM’s DVS 5000V and VMready demonstrate the healthy ecosystem in virtualization-aware networking and ensures that clients have freedom of choice to implement a multi-vendor network infrastructure that is equipped, enabled and scalable for massive virtualization.
Our standards-based approach enables clients to implement an integrated network across physical and virtual networks so the entire system-level network is aware of Virtual Machines and can automate their live mobility as workload requirements change. It’s truly a comprehensive solution that many clients are seeing as the way forward as they continue to embrace and extend virtualization across servers and workloads.
How do you see data center networks evolving to keep pace with the demands of massive virtualization?
OpenFlow – Next-Generation Networking for a Smarter Planet
We are seeing dramatic shifts as our planet becomes smarter. Every aspect of life is benefiting from the instrumentation, interconnection and the infusion of intelligence into the systems of the world. Networking is no exception, and the emerging OpenFlow specification promises a greater level of intelligence in Ethernet networks through a new approach called Software-Defined Networking (SDN).
OpenFlow is a network protocol that has been developed over the past six years at Stanford University. It was initially created for researchers and universities as a tool to allow experimentation with new protocols and is now showing great promise for today’s highly virtualized enterprise and cloud computing networks.
IBM is an industry leader in network virtualization technology and cloud computing through IBM System Networking's VMready product and is actively participating in the standardization of virtualization in networks through our leadership contribution to the IEEE 802.1Qbg standard. IBM is actively involved in OpenFlow technology.
OpenFlow is being promoted by the Open Networking Foundation formed by six companies that own and operate some of the largest networks in the world — Deutsche Telekom, Facebook, Google, Microsoft, Verizon and Yahoo! — as well as 17 member companies, including IBM and other major equipment vendors, networking and virtualization software suppliers and chip technology providers. OpenFlow is a disruptive technology that enables customers to choose their networking hardware and software separately in order to design best-of-breed data center solutions.
There are many applications for OpenFlow in modern networks. For example:
- A network administrator could create on-demand “express lanes” for voice and data traffic that are time-sensitive.
- Software could also be used to combine several fiber optic links into a larger virtual pipe for temporarily handing a particularly heavy flow of traffic, and then have the channels automatically separate again when the data rush is over.
- Service providers could use OpenFlow to help build a Smarter Planet by offering remote services such as home security or energy management.
- In cloud computing environments, OpenFlow improves scalability and enables resources to be shared efficiently among different services in response to the number of users.
OpenFlow revolutionizes the monolithic model of conventional network devices by managing the flow tables on network switches, routers and access points independently of the device’s software. It removes much of the network decision making, often called the “control plane” from network devices into an external controller that can be implemented using standard server technology.
At Interop Las Vegas, May 8-12, 2011, IBM System Networking and NEC will be showing, for the first time publically, a proof-of-concept demo of an OpenFlow-enabled IBM BNT RackSwitch G8264 working in concert with an NEC OpenFlow controller. IBM will also participate in the InteropNet OpenFlow Lab, which will educate attendees on the principles, functions and features of OpenFlow. The lab will demonstrate OpenFlow in different scenarios, including loop free networking, dynamic load balancing across multiple links and quality of service for VoIP.
We are proud to be one of the inaugural members of the Open Networking Foundation, which again demonstrates IBM’s long-standing commitment to making a difference for customers with open industry standards, which are essential for the Smarter Computing that powers a Smarter Planet.

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.
Cloud Computing for Rethinking IT and Reinventing Business
In IBM’s Global Chief Information Officer Study– “The Essential CIO” – based on a poll of 3,000 global CIOs– shows that cloud computing has come of age with interest in the cloud increasing more than any other CIO priority. As I mentioned earlier, this 2010 study shows that 60 percent of organizations are ready to embrace the cloud over the next five years, an increase that is nearly double that of the 2009 study.
The cloud represents a profound evolution of IT with revolutionary implications for business and society, creating new possibilities and enabling more efficient, flexible and collaborative computing models. The cloud enables “IT without boundaries”—systems and processes that break down traditional silos and simplify access to information in order to deliver better business outcomes. Cloud computing offers organizations dramatic increases in agility and efficiency— innovation to ensure speedy, cost-effective delivery of products and services. To realize the benefits of cloud computing while overcoming the inherent challenges, organizations must take a holistic approach that spans business and innovation, users and applications, systems and networks.
IBM enables Smarter Computing managed in the cloud with a wide range of solutions. For example, IBM Tivoli Service Automation Manager enables users to request, deploy, monitor and manage cloud computing services. IBM SmartCloud Managed Backup

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.
If you’re attending VMworld 2011, please make sure to learn more about VMready by visiting IBM in Booth #321.
Achieving More with Systems and Networks Tuned to the Task
IBM is the leader in workload-optimized systems that are tuned to the task. Analyst James Clabby of Clabby Analytics defines the workload-optimized system “as one that matches architecture to the needs it is purchased for. Systems performance is no longer defined by the fastest processor or other leading benchmarks, but rather by the ability to deploy new services faster, with higher quality and within financial objectives.”
IBM's leadership in workload-optimized systems spans more than four decades, leveraging significant investments in microelectronics R&D, software integration, and system networking and harnesses IBM’s vast experience of deploying systems to solve industry problems. For example, IBM is working with partners to deliver a comprehensive system to bring the power of analytics and get clients up and running quickly and affordably without risk. IBM provides the industry insight through services to test and tune the system to the client's exact specifications, works with partners to ensure their applications are optimized and offers financing to ensure the systems match clients' budgets.
Workload-optimized systems address many diverse workloads, such as industry-specific applications like Wall Street’s High Frequency Trading, cross-industry applications like business analytics, and configuration-specific IT environments like cloud computing and virtualization. For example, the IBM Smart Analytics System
is a fine-tuned hardware and software platform specifically designed for customized analytics applications in industries such as healthcare, financial markets, energy and retail. The widespread use of virtualization has led to the development of virtualization-optimized systems such as IBM BladeCenter HX5
with MAX5. The BladeCenter HX5 is a scalable blade server designed to provide new levels of utilization, performance, and reliability for virtualized workloads such as database, business intelligence, modeling and simulation, and other enterprise applications.
Workload-optimized systems extend into the networking arena, which is no longer solely defined by general-purpose infrastructures. IBM’s VMready
switch-resident, virtualization-aware networking software is a prime example of IBM System Networking technology developed specifically for today’s highly virtualized workloads, and can be deployed to optimize virtualization-oriented systems such as BladeCenter even further. With VMready, as VMs migrate across physical hosts, so do their network attributes automatically. VMready allows you to manage virtual machines as they are added, moved and removed while retaining the same ACLs, QoS and VLAN attributes anywhere across the data center network. VMready allows for a "define once, use many" configuration that optimizes the data center network infrastructure for broad deployment of virtualization.
James Clabby encourages a look beyond systems specifications and characteristics when choosing where to deploy applications to consider what a particular system is actually intended to do for an enterprise. I couldn’t agree more. I encourage clients to evaluate network infrastructure in terms of its ability to deliver speed and intelligence tuned to the task.
System Networking and Data Center Efficiency Redefined
The value proposition for IBM System Networking is to provide the essential network connectivity solutions under the IBM brand to connect servers to servers, servers to storage and storage to storage. IBM System Networking offers a compelling alternative for customers seeking more efficient data centers with the greatest business value and lowest total cost of ownership for their data center networks.
System networking plays a critical role in customers’ server and storage buying decisions. Today, many customers are deploying IT infrastructure on an unprecedented scale – data centers are expanding from 5,000 to 50,000 and 100,000 servers. For such scale-out architectures, the system network plays a critical role. Consider density; if it requires three data centers to house 5,000 servers, how many data centers will it take to house 50,000 servers? The answer better not be 30! So, the system network must deliver the high-density networking required to support highly consolidated and massively virtualized data center infrastructures.
If you are a CIO undertaking an order of magnitude increase in infrastructure, you want to increase utilization through virtualization, which requires the system network to be virtualization aware. And of course, the system network is vital to the security of this infrastructure.
If you have an order of magnitude increase in infrastructure, much of the functionality required to solve deployment and management issues can reside on data center switches implemented within the system network.
As companies take their businesses online, rapid and accurate business intelligence becomes ever more critical, which requires the system network for fast transport of information to and from analytic engines.
If you are employing an order of magnitude more infrastructure, total cost of ownership is important, and companies spend 15 to 20% of their investment in infrastructure on the network.
To address CIO’s key strategic issues of scaling, density, utilization/virtualization, security, data management and cost ownership, system networking is the common thread. IBM is an incredibly reputable server and storage vendor, and you can see the critical role the network plays.
