Key features
The Flex System Fabric CN4093 10Gb Converged Scalable Switch is considered particularly suited for the
following customers:
Customers who want to implement a converged infrastructure with FCoE where the CN4093 acts as
a Full Fabric FC/FCoE switch for the end-to-end FCoE configurations or as an integrated Fibre
Channel Forwarder (FCF) NPV Gateway that breaks out FC traffic within the chassis for the native
Fibre Channel SAN connectivity.
Customers who are implementing a virtualized environment.
Customers who require investment protection for 40 GbE external ports.
Customers who want to reduce total cost of ownership (TCO) and improve performance while
maintaining high levels of availability and security.
Customers who want to avoid or minimize oversubscription, which can result in congestion and
loss of performance.
The switch offers the following key features and benefits:
Convergence and lower acquisition and operational costs
One of the key trends that is driving the transformation of the data center is converging to a
simplified networking infrastructure, which collapses Ethernet and Fibre 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, Fibre Channel, iSCSI,
and FCoE; Omni Ports give customers the flexibility to choose between 10 Gb Ethernet external
connections to the top-of-rack switch and 4/8 Gb Fibre Channel for flexible and scalable access to
FC storage.
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, which makes 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. It also 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 customers to buy only the ports that are needed and
when needed. The base switch configuration includes 22x 10 GbE port licenses that can be
assigned to internal connections and external SFP+, Omni Ports, or 40 GbE QSFP+ ports (by using
four 10 GbE licenses per one 40 GbE port). Customers then have the flexibility of turning on more
internal 10 GbE connections and more external ports when needed by using Features on Demand
licensing capabilities that provide pay-as-you-grow scalability without the need for more hardware.
