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?
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:

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.

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.
Interop Las Vegas is Showcase for IBM’s Collaborative Innovations
Interop is a singular event that galvanizes our industry. This year at Interop Las Vegas May 8-12, IBM System Networking will showcase the latest developments in collaborative innovations for Smarter Computing. For example, the emerging OpenFlow specification promises a greater level of intelligence in Ethernet networks through a new approach called Software-Defined Networking (SDN).
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. We are proud to be one of the inaugural members of the Open Networking Foundation, which again demonstrates IBM’s long-standing commitment to open industry standards, which are essential for the Smarter Computing that powers a Smarter Planet.
At Interop Las Vegas, IBM System Networking and NEC will show in NEC’s booth #904, for the first time publically, a proof-of-concept demo of an OpenFlow-enabled high-performance 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.
IBM is also actively involving in open standards to better equip enterprise data centers for server virtualization. Edge Virtual Bridging (EVB) technologies, including the new Virtual Ethernet Port Aggregator (VEPA) technologies now being defined by the IEEE 802.1Qbg working group can make it easier for businesses to achieve server-network edge virtualization in the data center.
IBM’s Renato Recio is a driving force behind the 802.1Qbg standards, yet another of Renato’s numerous contributions to important industry standards that have dramatically simplified the way virtualized data centers operate. Renato was recently named an IBM Fellow, IBM’s most prestigious technical honor, recognizing his outstanding career of innovation that has so far resulted in 97 patents issued and 80 patents pending. I am proud to have Renato as a key member of our IBM System Networking team.
IBM System Networking’s switch-resident VMready with Virtual Vision is a unique EVB-ready solution that enables the network to be Virtual Machine aware, so that a data center network environment be configured, managed and secured for thousands of mobile Virtual Machines.
If you are attending Interop Las Vegas, May 8-12, please visit IBM in booth #621 to find out more about our leadership in collaborative innovations, such as OpenFlow and Edge Virtual Bridging.
The Cloud-Ready System Network
Today’s competitive business needs are driving the development of cloud-based data centers that are more cost-effective, agile, and scalable than ever before. Cloud computing places higher demands on the system network in areas such as speed, flexibility, virtualization, cost-effective operation and scalability. To meet the technical and business requirements of cloud computing, the networking layer of a cloud must offer high bandwidth and low latency, converged communications and storage, agile networks for virtual machine mobility, massive scalability and manageability and advanced energy efficiency.
The essential attributes of a cloud network include terabit scalability, predictable low latency, non-blocking throughput and high-speed interconnects using 1/10GbE and the emerging 40/100GbE. For example, the new IBM BNT RackSwitch G8264 delivers throughput of up 1.28 Terabits per second and with its single-chip architecture, low latency is delivered across all port combinations. To bring even more bandwidth to the cloud, the RackSwitch G8264 is among the industry’s first top-of-rack switches with 40GbE interconnects.
One of the main advantages of cloud computing is on-demand access to resources, and virtualization plays a key role in providing those resources. IBM System Networking's VMready network virtualization software enables cloud computing infrastructures with mobile, active virtual machines. Cloud computing users can gain even greater advantages from mobile virtual machines when they can be moved securely and with predictable performance not only within a cloud, but over greater distances to connect multiple clouds. Movement between clouds enables applications such as disaster recovery and data replication.
Today, cloud computing environments 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 must deliver the high-density networking required to support highly consolidated and massively virtualized data center infrastructures. Today’s “flat” network topologies enabled through standards such as TRILL (Transparent Interconnection of Lots of Links) are key to this scalability.
Power and cooling are some of the biggest expenses of operating a cloud data center. A common estimate for data center cooling and distribution costs is two watts for every single watt consumed by data center equipment and networking gear is 10 to 15% of the entire infrastructure —so choosing the most energy-efficient network components is essential. As clouds grow to thousands of servers and beyond, per-component power savings are magnified into hundreds of thousands of kilowatts.
From a business perspective, the system network architecture for today’s cloud computing applications must support incremental deployment that does not require razing an existing facility and building a new one. And as new pieces of the cloud are fitted into place, IT managers don’t want to be locked into a single-vendor implementation for any aspect of the solution. They want the freedom to select best-in-class hardware and software components, and they want to deploy new capacity as rapidly as possible. For example, IBM has extended Tivoli's virtualization management capabilities so that it can provision and deploy hundreds or thousands of virtual machines an hour for large-scale enterprise cloud implementations.
