What ports does the IBM EN4093R switch provide?

It offers 14 external SFP+ 10GbE ports and 2 external QSFP+ 40GbE ports, plus 42 internal full-duplex 10GbE ports to compute nodes. Base licensing enables 14 internal and 10 external 10Gb ports, scalable to 64x 10GbE with FoD upgrades for flexible datacenter connectivity.

What is the performance capability of this switch?

Delivers 1.28 Tbps aggregated throughput, 960 Mpps forwarding, sub-microsecond latency, and wire-speed performance with cut-through switching. Supports 9,216-byte jumbo frames and 9MB receive buffer, ideal for high-bandwidth virtualization and cloud workloads.

Is it compatible with Flex System chassis?

Yes, designed as a Flex System Blade Chassis module for I/O bays 1-4. Requires matching adapter cards in compute nodes using up to four lanes per bay, with two internal 1GbE ports to chassis management module for seamless integration.

What switching features are supported?

Layer 2/3 switching with OpenFlow, easy connect modes, Virtual Fabric, VMready, and SDN readiness. Includes 128K MAC entries, 4,095 VLANs, 64 link aggregation groups, IPv6 routing, OSPF, and DCB/CEE for converged networking.

How does it support virtualization?

Supports up to 32 vNICs per node with CN4054 adapters and four EN4093R switches. Unified Fabric Port (UFP) and port mobility optimize I/O, reducing modules by 66% while handling dynamic workloads with low latency.

What is the form factor and physical size?

Form factor is Flex System embedded I/O module: height 30mm, width 401mm, depth 317mm. Installs directly in Enterprise Chassis bays, conforming to industry standards for easy deployment in rack-scale datacenters.
