The ThinkSystem NE1032 RackSwitch is a 1U top-of-rack data center Ethernet switch designed for 10GbE server access and iSCSI or NAS storage connectivity. It offers thirty-two 10GbE SFP+ ports with non-blocking line-rate throughput and ultra-low latency down to 600 nanoseconds, running Lenovo Cloud Network OS (CNOS) or Enterprise NOS (ENOS). The switch supports standard Layer 2 and Layer 3 networking features including LACP, MLAG, VRRP, and BGP. Buyers of pre-owned units should verify whether CNOS or ENOS firmware is loaded and test airflow direction to ensure alignment with rack hot-aisle containment.

Works together

How the Lenovo ThinkSystem NE1032 connects to servers, storage and the network: 3 ways, with the parts and products on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

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.
