The ThinkSystem NE10032 RackSwitch is a high-bandwidth 1U 100GbE spine/leaf data center switch designed for cloud service providers, high-performance computing, and all-NVMe storage clusters. Featuring thirty-two 100GbE QSFP28 ports, it provides up to 6.4 Tbps of line-rate switching capacity and delivers ultra-dense breakout capability up to 128x 25GbE ports in a compact 1U enclosure. Operating on Lenovo Cloud Network OS (CNOS), it includes advanced Layer 3 routing, RoCE v2 congestion avoidance, and VXLAN hardware offloading. When purchasing pre-owned hardware, check QSFP28 transceiver contacts and verify matching fan tray airflow directions.

Works together

How the Lenovo ThinkSystem NE10032 connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.

Buying a used NE10032: what to check

Verify airflow direction on all power supply and fan modules; ensure CNOS boot loader initializes properly without hardware errors; test optical connectivity across QSFP28 cages.

FAQ

How many 25GbE connections can be established using breakout cables on the NE10032?

Up to 128x 25GbE ports can be established by breaking out all thirty-two 100GbE QSFP28 ports using 4-way splitter cables.

Does the NE10032 support hardware-based VXLAN?

Yes, the switch supports hardware-accelerated VXLAN encapsulation and EVPN Layer 2/3 gateway functions.
