SuperBlade® networking options include two different modules for Gigabit Ethernet connectivity. In addition Supermicro offers a powerful InfiniBand switch for connecting Blades to 4X DDR (20 Gbps) InfiniBand networks. All SuperBlade® networking options are hot-pluggable. The Ethernet modules can also be configured for redundant or dual load-sharing connections (or both).

Gigabit Ethernet Modules

Switches

The Gigabit Ethernet switch module (part ID SBM-GEM-001) includes ten external 1-Gb/s uplink (RJ45) ports and fourteen internal 1-Gb/s downlink ports for connection to the SuperBlade®'s LAN interfaces. This layer 2 Ethernet switching module also has two internal Ethernet paths to the CMM(s) to allow configuration, management, and control of the switch and its ports through a browser-based management interface. Offering such advanced features as "trunking" (Link Aggregation – IEEE 802.11ad), VLAN support, and Jumbo Frame support, the switch provides a connection between the Ethernet controller integrated on the mainboard and external Ethernet systems.

Pass-Through

The Gigabit Ethernet Pass-through Module (part ID SBM-GEM-002) is a non-configurable pass through module that includes fourteen 1-Gb/s external uplink (RJ45) ports and fourteen internal 1-Gb/s downlink ports for the SuperBlade®'s LAN interfaces. This module also has two internal Ethernet paths to the CMM(s) for viewing module temperature and voltage (but not for configuration since all connections are fixed).

InfiniBand Modules

InfiniBand Switch Module

The InfiniBand Switch Module (part ID SBM-IBS-001) is a switch-based, point-to-point bi-directional serial link system. It provides high-speed interconnectivity among the blade modules and to external InfiiniBand peripherals. The InfiniBand switch supports 4X DDR connections – 20 gigabits per second – the fastest currently offered in the industry.

InfiniBand Mezanin HCA Cards

For any blade to access the InfiniBand module, it must have an InfiniBand mezzanine HCA card installed on its mainboard. The AOC-IBH-001 and AOC-IBH-002 mezzanine cards provide this 20Gbps connectivity (4x DDR) through the backplane to the InfiniBand switch module.
