Cisco Data Center 3.0 Strategy
Cisco Nexus 5000 Series
• Unified Fabric: The Cisco Nexus 5000 Series delivers the capability to consolidate IP, storage, and server clustering networks on a unified fabric over Ethernet. This capability reduces the number of server interfaces and simplifies cable management, resulting in lower costs, more efficient operations, and investment protection for current data center resources. This unified fabric is delivered through open standards using protocol technologies such as Fibre Channel over Ethernet (FCoE) and IEEE Data Center Bridging (DCB) in partnership with a broad group of market-leading vendors.
• Virtual machine optimized services: One of the most significant challenges faced by IT organizations when trying to build a virtualized data center is the difficulty of orchestrating provisioning and mobility of virtual machines while preserving network services and capabilities. The Cisco Nexus 5000 Series delivers VM (Virtual Machine) optimized services, supporting the Data Center 3.0 vision by allowing IT organizations to dynamically respond to changing business demands through rapid provisioning of application and infrastructure services from shared pools of consolidated compute, storage, and network resources. Virtual machine deployments rely on a combination of LAN traffic, SAN traffic and Server Clusters to implement VM infrastructure services such as VM mobility; all of which can be implemented on a unified fabric delivered by the Cisco Nexus 5000. The Cisco Nexus 5000 series supports end-port virtualization, where the switch takes ownership of the Layer 2 connectivity for connected servers. This approach simplifies the network, supporting massive scale, high-performance active/active links, and fine-grained control over network resources.
The Cisco Nexus 5000 Series switches are not a tactical point product, but rather a holistic solution to address near-terms needs while also integrating into a long-term business and technical strategy. The solution consists of several elements:
• Partnerships: The Cisco Nexus 5000 Series is an open, standards-based platform supported by a broad group of partners. These partners provide converged network adapters (CNAs) that allow both LANs and SANs to be accessed from one adapter using existing operating systems and drivers, and a low-latency, low-cost cable and transceiver combination that dramatically decreases power consumption. With its standards-based, open partnership approach, the Cisco Nexus 5000 Series helps ensure end-to-end data center architectural integrity, providing improved business continuity, security, and resiliency.
• Cisco Nexus 5000 Series Switches: Built for high-performance, Unified Fabric delivery over Ethernet, the series provides investment protection for current data center assets and the performance and operational characteristics necessary to keep pace with growing business needs for many years to come.
• Cisco NX-OS Software operating system: This Linux-based operating system combines the lossless architecture of Cisco MDS 9000 SAN-OS Software with the Layer 2 and 3 protocol richness of Cisco IOS® Software.
• Cisco Data Center Network Manager (DCNM): This Cisco Nexus family management tool increases operational efficiency, a key design goal of unified fabric delivery.
• Full portfolio of lifecycle services: Cisco offers a comprehensive suite of services to support enterprises in the design, implementation, and operation of the Cisco Data Center 3.0 strategy. Specifically, Cisco offers professional services to help customers assess the benefits of migration to a unified fabric as well as support to design, plan, implement, and maintain that migration.
• Cisco Data Center Assurance Program (DCAP): Cisco DCAP provides a unique system-level tested and documented validation of Cisco (and third-party vendor) data center technologies to assist customers in the design and implementation of data center infrastructures. Cisco DCAP offers customers a validated baseline data center infrastructure that includes designs, configurations, test plans, test results, and recommended software selections.
Cisco Nexus 5000 Series: Benefits of Unified Fabric Delivery
• Lower TCO: The Cisco Nexus 5000 Series provides a unified fabric over Ethernet for LAN, SAN, and server cluster traffic. This unified fabric provides consolidation and higher utilization of previously separate resources, reducing the number of server I/O adapters and cables by as much as 50 percent and lowering power and cooling costs by up to 30 percent through the elimination of unnecessary switching infrastructure. The simplified infrastructure will also lower operational expenses related to management and operations.
• Investment protection: The evolution to a Unified Fabric will happen gradually as compelling business and technical factors present themselves. The Unified Fabric provided by the Cisco Nexus 5000 Series allows organizations to preserve the investment they already have in their existing Ethernet and Fibre Channel infrastructure during this transitional period. The Cisco Nexus 5000 Series is designed to allow customers to take advantage of the immediate benefits of a unified fabric without compromising architectural, management, or operational best practices in either Ethernet or Fibre Channel networks. This approach allows customers to take advantage of the platform's benefits without having to invest in extensive staff training, rewrite network architecture plans and operating procedures, or endure the risks associated with a complete architectural makeover.
• Increased business agility: The Cisco Nexus 5000 Series supports virtual machine server cluster, enabling applications to move across the network while maintaining their provisioned network services, such as security policy, quality of service (QoS), and overall performance. As a result, IT managers can easily move applications based on factors such as CPU utilization and thermal loads. This capability allows IT departments to rapidly respond to changing business demands through rapid provisioning of the dynamic and flexible application infrastructure enabled by the combination of server virtualization and the Cisco Nexus 5000 Series virtual machine optimized services.
• Enhanced business resilience: As should be expected of any data center-class infrastructure, the Cisco Nexus 5000 Series is engineered with specific hardware and operating systems to deliver component- and system-level operational continuity. In addition to offering component-level protection, the Cisco Nexus 5000 Series can have a significant positive effect on a customer's business continuance capabilities. Virtual machine optimized services helps ensure that applications can be quickly and transparently moved to a new infrastructure in response to challenges such as hardware failure or unexpectedly high application use. Similarly, in a recovery scenario, the simplified infrastructure and consistent I/O capabilities facilitate service recovery: no more "we cannot use that server; it's big enough, but it does not have a Fibre Channel host bus adapter."
