About Network Express Modules (NEMs)

The Sun Blade 8000 Modular System supports up to four Network Express Modules (NEMs). The Sun Blade 8000 P Modular System supports up to two NEMs. NEMs connect via the system midplane to all 10 blades in the chassis and appear to the blades as standard PCI Express (PCIe) adapters.

Designed within a Sun proprietary form factor, these switchless networking devices provide a dual Gigabit NIC for each blade. For the Sun 20-Port Gigabit Ethernet (GbE) NEM and the Sun StorageTek 4Gb Fibre Channel (FC) NEM, there are up to 20 RJ-45 Ethernet interfaces providing 10/100/1000BASE-T ports at the chassis rear. For the Sun 10-Port 4x DDR InfiniBand (IB) PCI Express (PCIe) NEM, there are 10 ports at the chassis rear.

Each NEM supports an industry-standard hot-plug capability.
