Increased 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 Flex
System 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 external bandwidth by being the
integrated switch to support 40 GbE external ports.
Pay as you grow investment protection and lower total cost of ownership
The CN4093's flexible port mapping allows you to buy only the ports that you need, when you need
them. The base switch configuration includes 22x 10 GbE port licenses that can be assigned to
internal connections and external SFP+, Omni or 40 GbE QSFP+ ports (by using four 10 GbE licenses
per one 40 GbE port). You then have the flexibility of turning on more internal 10 GbE connections and
more external ports when you need them using Features on Demand licensing capabilities, that
provide "pay as you grow" scalability without the need for additional hardware.
Cloud ready - 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. Lenovo is helping to address these
requirements by removing multiple physical I/O ports. Virtual Fabric provides a way for companies to
carve up 10 GbE ports into virtual NICs (vNICs) to meet those requirements with Intel processor-based
compute nodes.
To help deliver maximum performance per vNIC and to provide higher availability and security with
isolation between vNICs, the switch leverages capabilities of its Networking Operating System. For
large-scale virtualization, the 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.
The CN4093 offers the benefits of next-generation vNIC - Unified Fabric Port (UFP). UFP is an
advanced, cost-effective solution that provides a flexible way for clients to allocate, reallocate, and
adjust bandwidth to meet their ever-changing data center requirements.
Cloud ready - VM-aware networking
Delivering advanced virtualization awareness helps simplify management and automates VM mobility
by making the network VM aware with VMready, which works with all the major hypervisors. For
companies using VMware, SDN for Virtual Environments (sold separately) enables network
administrators to simplify management by having a consistent virtual and physical networking
environment. With SDN VE, virtual and physical switches 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 compute node to compute
node.
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 compute node 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.
