Scalent And 3Leaf Systems Announce Interoperability Of Infrastructure Repurposing And Virtualization Solutions

Collaboration Delivers Increased Data Center Resource Utilization, Availability,
and Agility While Improving Wide Area Disaster Recovery

PALO ALTO, Calif.—June 19, 2007— Scalent Systems, the leading provider of server repurposing software for large data centers, and 3Leaf Systems, provider of next-generation virtualization solutions for enterprise data centers, today announced a relationship between the two companies that allows seamless interoperability between the Scalent V/OE software and 3Leaf V-8000 Virtual I/O Server in customers’ heterogeneous IT environments. Together, the two enterprise-level solutions provide customers with guaranteed service levels (SLAs) and consistent connectivity between servers, networks, and storage even as servers are repurposed in real-time for planned business shifts or unplanned business continuity reasons.

Data center managers are increasingly looking to achieve greater management control, higher utilization and improved availability of server resources. Traditionally, server repurposing – changing which servers are running, what software is running on them, and how they’re connected to network and storage – has been a time- and cost-prohibitive activity. With Scalent V/OE and the 3Leaf V-8000 Virtual I/O Server, server infrastructure repurposing can be achieved in minutes, without physical cable moves or resource reconfiguration, while maintaining service level agreements.

Scalent V/OE enables any managed server software stack to boot from and access specific SAN LUN segments from any physical or virtual machine – on the fly, without requiring changes to underlying physical assets. The 3Leaf V-8000 virtualizes the I/O for large pools of servers, delivering limits and guarantees to both networking and storage interfaces, allowing service levels to be dynamically modified as application demand changes. This greatly improves resource utilization, and ensures priority applications are running efficiently at mainframe-class availability. The joint solution enables any server to take on the personality of any other machine at any time while maintaining consistent connectivity, and allows I/O resource allocation to scale as application requirements change. This ability to dynamically reuse, redeploy, and scale current IT assets delivers increased flexibility, lowers capital and management costs, reduces the need for infrastructure changes and improves system failover recovery, rollout and repurposing.

“By non-intrusively unshackling physical and virtual servers from their software stack, LAN and SAN dependencies, Scalent and 3Leaf enable data center owners to match their existing infrastructure to changing business needs in real time, without disrupting application performance or business processes,” said Ben Linder, chief executive officer of Scalent Systems. "We’ve seen remarkable total cost of ownership savings in deployed customer environments, and we are excited to work with 3Leaf, whose architecture minimizes the cost of deploying commodity servers by removing the need for local storage and connectivity components while enhancing server availability and resiliency.”

"3Leaf in collaboration with Scalent dramatically reduces the complexity of server movement in or across data centers, consolidating both storage and networking infrastructures while delivering guaranteed service levels and lowering costs," said Bob Quinn, chief executive officer of 3Leaf Systems. “Now every server can be deployed dynamically and inexpensively. The Scalent V/OE software and the 3Leaf server virtualization solutions are the right way to address asset utilization for maximum business benefit without changing existing infrastructures.”

3Leaf Systems and AMD Work Together To Develop Next-Generation Virtualization Technologies

Collaboration Delivers Best-of-Class Server Virtualization Solutions to
Improve Resource Utilization and Performance in Fortune 500 Data Centers

SANTA CLARA, Calif. —June 12, 2007 —3Leaf Systems, a provider of server virtualization solutions for next-generation data centers, today announced a relationship with AMD that aligns the two companies in the development of 3Leaf's Virtual Compute Environment (VCE), an advanced virtualization architecture that enables mainframe-class capabilities for commodity servers. The first product on 3Leaf's VCE roadmap, the 3Leaf V-8000 Virtual I/O Server, was officially unveiled last month and it was developed using AMD64 technology. The 3Leaf V-8000 virtualizes the I/O for x86-based servers, supporting the entire line of AMD Opteron™ processors. Future products on the 3Leaf roadmap will continue to expand the AMD relationship by leveraging coherent HyperTransport™ technology, which 3Leaf has licensed.

"3Leaf Systems is an ideal partner for AMD, because it supports our commitment to performance-per-watt leadership and extends the value of AMD Virtualization™," said Randy Allen, corporate vice president and general manager, Server/Workstation Division, AMD. " We will continue to work closely with 3Leaf to offer solutions that improve the overall utilization and performance of our customers' large-scale, AMD Opteron processor-based data centers."

The 3Leaf Virtual Compute Environment delivers system-level virtualization across multiple racks to enable mainframe-class capabilities for commodity servers. With 3Leaf Systems' server virtualization solutions, organizations can significantly reduce their investments in infrastructure and operations, rapidly deploy and provision data center resources, and ensure resources are available to meet the unique business and performance requirements of today's data center applications.

"AMD continues to be a catalyst for breakthrough processor innovations that power global business," said Bob Quinn, CEO of 3Leaf Systems. "We are excited to be working closely with AMD to quickly bring to market leading-edge server virtualization solutions that will help unlock the enormous untapped potential of scale-out data center architectures."

3Leaf Systems Sets New Standard In Virtualization With Debut Of Virtual I/O Server

V-8000 Delivers Mainframe-Class Capabilities for Commodity Servers
in Large Scale-out Environments

SANTA CLARA, Calif.—May 1, 2007—3Leaf Systems, provider of next-generation virtualization solutions for enterprise data centers, today introduced the 3Leaf Systems V-8000 Virtual I/O Server. Virtualizing the I/O subsystems for large pools of servers, the V-8000 delivers mainframe-class availability and resiliency for commodity systems while dramatically reducing both capital and maintenance costs.

The V-8000’s rich feature set addresses the challenges facing today’s enterprise data centers by maximizing server resource utilization and scalability, speeding up the deployment and provisioning of new servers, and providing high availability and centralized management while reducing both capital and operating costs. Capital expenditure savings from deploying the V‑8000 can exceed 50 percent on day one, and operations savings can be close to 60 percent.

Virtual Compute Environment™ Delivers Scale-up Resiliency and Availability
The first offering on 3Leaf’s roadmap of virtualization solutions, the V-8000 delivers scalable I/O connectivity for servers residing in the 3Leaf Virtual Compute Environment (VCE). In addition to providing highly scalable and efficient I/O, the VCE architecture minimizes the cost of putting commodity servers into service by removing the need for local networking and storage. The servers are stateless, commodity nodes that efficiently connect to virtual Network Interface Cards, virtual Host Bus Adapters, and virtual disks through the V-8000. This I/O consolidation results in fewer connections to the data and storage networks supporting the VCE, which translates into capital savings; and because there is less to manage, overall operating expenditures are reduced as well.

Cost savings are driving the overall IT consolidation market, which IDC projects will grow from $18.1 billion in 2004 to $24.7 billion in 2009, outpacing growth of the overall IT market worldwide. Virtualization software sales are expected to rise from $340 million to $15 billion during that period — almost a 50-fold increase.

“Traditional scale-out server architectures, when installed and managed on a large scale, have a very high total cost of ownership, due to the physical complexities of configuring and connecting so many servers and the amount of time required for initial provisioning and reprovisioning,” said Mike Kahn, managing director of The Clipper Group, technology acquisition consultants based in Wellesley, Mass.  “3 Leaf Systems' Virtual Compute Environment changes all of that while also improving the scalability, effective capacity, and availability of the underlying servers.  Their approach makes a lot of sense!”

V-8000 Features and Benefits

Faster server deployment: The V-8000 enables fast deployment of new servers in two ways. First, because the V-8000 allows servers to be defined in advance, spare nodes can have new profiles applied in a matter of minutes rather than weeks or months. Second, network and storage do not necessarily need to be involved every time a new server is put into service, because the network and storage interfaces have been pre-allocated to these profiles. The streamlined deployment enabled by the V-8000 increases efficiencies and lowers operating costs.

Quality of service for both networking and storage: The V-8000 allows I/O resources to be allocated using quality of service parameters, which delivers limits and guarantees to both networking and storage interfaces, allowing service levels to be dynamically modified as application demand changes. This results in greatly improved utilization of I/O resources, and ensures priority applications are running efficiently and delivering mainframe-class availability.

High availability, reduced downtime: The V-8000, along with the VCE, delivers high resiliency by reducing the number of components, including local discs, excess network and storage adapters, and switch ports in the data and storage networks. In addition, the software infrastructure is more efficient – and the result of reducing the number and flavors of drivers is less downtime. High availability is supported two ways: First, in case of a failure, the V‑8000 automatically fails over to a redundant V-8000 with redundant networking and storage interfaces. Second, the V-8000 has built-in redundancy for storage and networking, with the ability to automatically discover redundant storage paths and bond together redundant networking paths. The V-8000 delivers higher availability and resiliency at half of the cost of today’s infrastructure.

“3Leaf’s value proposition immediately resonates with enterprise companies that are looking for ways to effectively deal with the headaches of server deployment, increasing costs while still at very low utilization levels, and the complexities of managing all of their computing resources,” said Bob Quinn, CEO, 3Leaf Systems. “We anticipate continued company growth and increased product demand based on the market drivers for a solution such as ours, and the significant customer traction we have gained in a short period of time.”
