Convergence and flexibility:
One of the key trends that is driving the transformation of the data center is converging to a simplified networking infrastructure - collapsing Ethernet and Fiber Channel at the server and the edge of the network while maintaining connectivity upstream to existing LANs and SANs. The CN4093 Converged Switch supports multiple protocols, including Ethernet, Fiber Channel, iSCSI, and FCoE; IBM Omni Ports give clients the flexibility to choose between 10 Gb Ethernet uplink connections to the top-of-rack switch and 4/8 Gb Fiber Channel for flexible, scalable, and convenient access to FC storage.
Increased network performance:
With the growth of virtualization and the evolution of cloud, many of today's applications require low latency and high bandwidth performance. The CN4093 is the embedded 10 GbE switch for a server chassis to support sub-microsecond latency and up to 1.28 Tbps, while also delivering full line rate performance on Ethernet ports, making it ideal for managing dynamic workloads across the network. In addition, this switch provides a rich Layer 2 and Layer 3 feature set that is ideal for many of today's data centers. Furthermore, it offers industry-leading uplink bandwidth by being the integrated switch to support 40 Gb uplinks.
Pay as you grow flexibility:
The CN4093's flexible port licensing allows you to buy only the ports that you need, when you need them. The base switch configuration includes fourteen 10 GbE connections to the servers, two 10 GbE uplinks, and six Omni Ports for either 10 GbE or 4/8 Gb FC connections. You then have the flexibility of turning on more 10 GbE connections to the server and more Omni Ports or 40 GbE uplinks when you need them using Features on Demand licensing capabilities, which provide pay as you grow scalability without the need for additional hardware.
Optimized network virtualization with virtual NICs:
With the majority of IT organizations implementing virtualization, there has been an increased need to reduce the cost and complexity of their environments. IBM is helping to address these requirements by removing multiple physical I/O ports. IBM Virtual Fabric provides a way for companies to carve up 10 Gb ports into virtual NICs (vNICs) to meet those requirements with Intel processor-based servers. To help deliver maximum performance per vNIC and to provide higher availability and security with isolation between vNICs, the switch leverages capabilities of its IBM Networking Operating System. For large-scale virtualization, the IBM Flex System solution can support up to 32 vNICs by using a pair of CN4054 10Gb Virtual Fabric Adapters in each compute node and four CN4093 10Gb Converged Scalable Switches in the chassis.
Delivering advanced virtualization awareness helps simplify management and automates VM mobility by making the network VM aware with IBM VMready, which works with all the major hypervisors. For companies using VMware, IBM System Networking's Distributed Virtual Switch 5000V (sold separately) enables network administrators to simplify management by having a consistent virtual and physical networking environment. 5000V virtual and physical servers use the same configurations, policies, and management tools. Network policies migrate automatically along with virtual machines (VMs) to ensure that security, performance, and access remain intact as VMs move from server to server. 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.
Simplify network infrastructure:
The CN4093 10Gb Converged Scalable Switch simplifies deployment and growth by using its innovative scalable architecture. This architecture helps increase return on investment by reducing the qualification cycle, while providing investment protection for additional I/O bandwidth requirements in the future. The extreme flexibility of the switch comes from the ability to turn on additional ports as required, both down to the server and for upstream connections (including 40 GbE). Also, as you consider migrating to a converged LAN and SAN, the CN4093 supports Omni Ports for Ethernet or FC connectivity, and it can operate as an integrated FCF, which can be leveraged in an FCoE converged environment.
Integrate network management:
A key challenge is the management of a discrete network environment. The CN4093 10Gb Converged Scalable Switch is tightly integrated and managed through the IBM Flex System Manager. The switch also supports a command-line interface (CLI) for integration into existing scripting and automation. Network management can be simplified by using port profiles, topology views, and virtualization management.
