NSComm E700 Series 100G Data Center Leaf Switches

NSComm E700 Series 100G Data Center Leaf Switches

NSComm E700 Series switches are high-density 100G data center leaf switches built around QSFP28 connectivity. The collection includes the 32-port E730-32C and 64-port E780-64C, giving network teams two port-density options for L2/L3 fabric and server connectivity.

Choose Between 32-Port and 64-Port 100G Designs

Select the E730-32C for a focused 32 x 100GE deployment or the E780-64C when the rack or fabric design requires 64 x 100GE QSFP28 ports. Matching port count to the actual topology helps control capacity, cabling, and expansion planning.

100G QSFP28 Connectivity

Both models use 100GE QSFP28 interfaces, making this collection relevant for buyers comparing a 100G switch, 100G network switch, or 100GB Ethernet switch for modern data center networks.

Where the E700 Series Fits

Leaf-Spine Data Center Networks

The E730 and E780 models are positioned as leaf switches for high-speed rack and fabric connections. Validate the intended leaf-spine architecture, neighboring devices, and link requirements before choosing a model.

High-Density Server and Fabric Connectivity

Use the available 100G port density to support dense server, storage, aggregation, or fabric connections where a data center network switch must consolidate many high-bandwidth links.

Data Center Upgrade Planning

For migrations from lower-speed platforms, compare current traffic demand, future port growth, optic reach, and cabling type before moving to a 100G Ethernet switch design.

Plan the E700 Deployment

Validate Optics and Cabling

Confirm QSFP28 module, DAC, AOC, connector, distance, and interoperability requirements for every link. The exact transceiver or cable choice should match the peer device and deployment distance.

Check Port Density and Oversubscription

Map required active links and expected traffic to either 32 or 64 ports, then review oversubscription and redundancy targets at the rack and fabric levels.

Confirm L2/L3 Requirements

Define VLAN, routing, management, redundancy, and software requirements before procurement. Final feature support should be checked against the exact model and software release.

Compare NSComm E700 Models

NSComm E730-32C

Choose the E730-32C when the design calls for 32 x 100GE QSFP28 ports in a managed L2/L3 data center leaf switch.

NSComm E780-64C

Choose the E780-64C when the design requires 64 x 100GE QSFP28 ports and higher leaf-switch port density.
