Network connection

This section describes the network connection for /390 servers and x86 servers.

Information on the performence including measurements can be found in section "Measurements for LAN connections on SE servers".

Network connection via HNC (/390 servers)

/390 servers are connected to a LAN (Local Area Network) via an HNC (High-speed Net Connect) channel adapter.

The HNC is a high-performance network connection for BS2000 systems on /390 servers, see the “HNC” manual [13 (Related publications)].

Network connection via LAN board (x86 servers)

x86 servers are connected to a LAN by means of an integrated controller (PCIe controller). Like all I/O operations, the I/O operations to the integrated controller are routed via the I/O processor.
