Lenovo Flex System EN4023 10Gb Scalable Switch
Product Guide
The Lenovo® Flex System™ EN4023 10Gb Scalable Switch is a high-performance 10 Gigabit Ethernet (GbE)
embedded switch that supports the most demanding business applications. It is designed for both LAN and SAN
environments, offering Layer 2 and Layer 3 features for the LAN and support for connectivity to almost any kind
of SAN including FCoE, Fibre Channel, iSCSI, and NAS storage.
The EN4023 is one of the most flexible switches in the blade market and also leverages Brocade’s Virtual Cluster
Switching (VCS) Fabric which is designed to improve network utilization, maximize application availability,
increase scalability, and dramatically simplify network deployment and management.

Did you know?
The EN4023 switch features Brocade VCS Fabric technology that enables organizations to build high-
performance, cloud-optimized data centers while preserving existing network designs and cabling, and gaining
active-active server connections. Brocade VCS Fabric technology provides a scale-out architecture which allows
organizations to flatten network designs, provide virtual machine (VM) mobility without network reconfiguration,
and manage the entire fabric more efficiently.
The EN4023 is the industry's first offering that supports 16 Gbps Fibre Channel connectivity on an embedded
FCoE switch, which makes the EN4023 the best choice for flash storage, databases, or other environments that
need more storage bandwidth.
The EN4023 is one of the lowest latency switches for Ethernet and FCoE traffic, and it utilizies a single ASIC
design to achieve sub-microsecond port to port latencies, while also providing one of the largest aggregated
throughput of 1.28 Tbps. Additionally, the EN4023 can support more FC uplinks than any other vendor’s
converged switch by using an optional Flex Port technology license upgrade.
