Lenovo Flex System Fabric EN4093R 10Gb Scalable Switch

Performance for the Future

The Lenovo® Flex System Fabric EN4093R 10Gb Scalable Switch provides unmatched scalability, port flexibility, and performance. The switch also delivers innovations to help address several networking concerns today and provides capabilities that help you prepare for the future.

This switch can support up to 64x 10 Gb Ethernet connections while offering Layer 2/3 switching, in addition to OpenFlow and "easy connect" modes. It installs within the I/O module bays of the Flex System™ Enterprise Chassis. This switch can help clients migrate to a 10 Gb or 40 Gb Ethernet infrastructure, offers cloud-ready virtualization features (such as Virtual Fabric and VMready®), and is Software Defined Network (SDN) ready.

Increase Performance

With the growth of virtualization and the evolution of cloud, many of today’s applications require low latency and high bandwidth performance. To enable integration into the higher bandwidth networks supporting cloud services, the industry leading EN4093R is the first blade switch to feature 40Gb external ports. Additionally, the Flex System Fabric EN4093R is the first blade switch to support sub-microsecond latency, while also delivering full line-rate performance of up to 1.28TBps, making it ideal for managing dynamic workloads across your network.

Scalability and Flexibility

The EN4093R provides extreme scalability that can help reduce cost and complexity and enable rapid deployment today or in the future. Pay-as-you-grow scalability allows clients to easily and cost effectively enable additional ports through the purchase of a simple software license key. Additionally, the new flexible portmapping feature offers unmatched configuration customization by allowing any active port on the EN4093R to be designated as either an internal or external port. This port mobility capability enables I/O connectivity optimization within the Flex System chassis. With this capability, a client can deploy a pair of EN4093R modules to support an application requiring six 10Gb server ports. Supporting this application would require others to deploy up to 6 Ethernet modules. Consequently, this provides clients with up to 66%† fewer devices to manage, thereby lowering operational costs and reducing power requirements.

Cloud Ready

With the majority of IT organizations implementing virtualization, there has been an increased need to reduce the cost and complexity of their environments. Removing multiple physical I/O ports addresses these requirements. Virtual Fabric provides a way for you to separate a pair of 10Gb ports into virtual NICs (vNIC) to meet those requirements. To help deliver maximum performance per vNIC, plus provide higher availability and

security with isolation between vNIC’s, the switch leverages capabilities of its networking operating system. Furthermore, the EN4093R offers 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. In addition, delivering advanced virtualization awareness helps simplify management and automates VM mobility by making the network VM-aware—for all major hypervisors—with VMready. With Switch Partition (SPAR), clients can virtualize the switch with partitions that isolate communications for multi-tenancy environments.

Software-defined Network Ready

Today some data centers are gravitating toward a new environment; one that is software defined. With the proliferation of big data and devices like smart phones, data centers must be agile and responsive. Even with recent advances, the physical network often lacks the flexibility needed to accelerate business success. Flex System and the EN4093R support OpenFlow in a blade server chassis. This enables the EN4093R to be deployed as a network element in a broader OpenFlow network and obtain flow directions from a centralized OpenFlow controller.
