Compute Connectivity August 2014 Series 88 Compute Connectivity Design Overview Server virtualization offers the capability to run multiple application servers on a common hardware platform, allowing an organization to focus on maximizing the application capability of the data center while minimizing costs. Increased capability and reduced costs are realized through multiple aspects: • Multiple applications can be combined in a single hardware chassis, reducing the number of boxes that must be accommodated in data-center space • Simplified cable management, due to fewer required cable runs and greater flexibility in allocating network connectivity to hosts on an as-needed basis • Improved resiliency and application portability as hypervisors allow workload resiliency and load-sharing across multiple platforms, even in geographically dispersed locations • Applications that are deployed on standardized hardware platforms, which reduces platform- management consoles and minimizes hardware spare stock challenges • Minimized box count reduces power and cooling requirements, because there are fewer lightly loaded boxes idling away expensive wattage The ability to virtualize server platforms to handle multiple operating systems and applications with hypervisor technologies building virtual machines allows the organization to lower capital and operating costs by collapsing more applications onto fewer physical servers. The hypervisor technology also provides the ability to cluster many virtual machines into a domain where workloads can be orchestrated to move around the data center to provide resiliency and load balancing, and to allow new applications to be deployed in hours versus days or weeks. The ability to move virtual machines or application loads from one server to the next, whether the server is a blade server in a chassis-based system or a standalone rack-mount server, requires the network to be flexible and scalable, allowing any VLAN to appear anywhere in the data center. Cisco Virtual Port Channel (vPC) and Fabric Extender (FEX) technologies are used extensively in this data center design to provide flexible Ethernet connectivity to VLANs distributed across the data center in a scalable and resilient manner. Streamlining the management of server hardware and its interaction with networking and storage equipment is another important component of using this investment in an efficient manner. Cisco offers a simplified reference model for managing a small server room as it grows into a full-fledged data center. This model benefits from the ease of use offered by Cisco UCS. Cisco UCS provides a single graphical management tool for the provisioning and management of servers, network interfaces, storage interfaces, and the network components directly attached to them. Cisco UCS treats all of these components as a cohesive system, which simplifies these
