Features and benefits
Data centers continue to evolve. This evolution creates a need for an infrastructure that can support growth in
Virtual Machines (VMs), distributed applications, and data, as well as the transition to cloud-based computing —
without compromising performance. However, traditional data centers typically use inflexible, three-tier network
designs that cannot efficiently manage east-west traffic or deliver the bandwidth needed to support virtualization
and new service delivery. In addition, with the movement toward cloud computing, the importance of deploying a
flexible and responsive network infrastructure only grows.
To support the new direction of IT service delivery, data center operators need networks that are high
performance, operationally efficient, automated, and elastic. The ideal network will be easy to manage and scale
to meet demand as well as adapt to future requirements.
The EN4023 switch offers the following key features to meet raising networking requirements of data centers:
Extreme flexibility for LAN and storage networking
The EN4023 supports Layer 2, Layer 3 networking in addition to providing advanced storage support with
multiple storage connectivity options, including FCoE, Fibre Channel, iSCSI, and NAS storage. Data
Center Bridging (DCB) enables the reliable exchange of storage traffic over the LAN network, eliminating
packet loss when network congestion occurs and allocating bandwidth as needed to keep the network
running efficiently. The switches offer Network Attached Storage (NAS) Auto QoS intelligence to prioritize
delay-sensitive IP storage traffic within the fabric and help ensure consistent performance while
decreasing latency.
Unmatched port flexibility and configuration simplicity
The EN4023 switch can help reduce cost and complexity with Dynamic Ports on Demand (DPOD), which
automatically activates ports as compute nodes, cables, or transceivers are plugged in. No manual
settings required to turn ports on or off.
The base license supports 24 ports and allows all 14 slots in the Flex System chassis to connect to an
upstream switch with an oversubscription ratio better than 2:1 when using 2-port Ethernet adapters.
Additional licenses can be purchased allowing "pay as you grow" scalability for additional bandwidth while
still having an affordable price.
Unrivalled scalability and simplified management
The EN4023 switch supports for up to 48 switches managed through one IP address. This allows up to 24
chassis and 336 compute nodes to be added to this single managed unit, making it easy for clients to
deploy PODs or clusters with a single logical chassis requiring no networking beyond what is provided in
a Flex System chassis.
Industry leading virtualization and cloud ready innovations with Brocade VM-aware Network Automation.
The EN4023 supports Automatic Migration of Port Profiles where the Brocade VCS fabric directly
communicates with VMware vCenter and its status, being the first blade embedded switch with VXLAN
support. VNIC technology that is switch independent can also be run through the EN4023.
Unequalled SDN features and capabilities
The EN4023 can help clients simplify administration through OpenFlow 1.3, OpenStack, Puppet, and
Python while still including an industry standard CLI for easy transition of administrator skill sets.
Brocade VCS fabrics running on the Brocade VDX family of switches (like the EN4023) allow organizations to
create data center networks that just work. Together, these technologies (Layer 2, Layer 3 and Storage) provide
unmatched automation, efficiency, and elasticity in support of the most demanding workloads. The EN4023
switch offers the following benefits:
