Saturn Blade networking options include four different Ethernet modules. For simple Layer 2 switching at 1-Gbps the SBM-GEM-001 switch offers a cost-effective connectivity option. The SBM-GEM-002 1-Gbps Ethernet Pass-Through module provides an even lower cost access option where switched access is not required.
Access to 10-Gigabit Ethernet networks is provided by either the Layer 2/3 1/10-Gbps Ethernet Switch - SBM-GEM-X2C or the 10-Gigabit Ethernet Pass-Through Module - SBM-XEM-002.
In addition Saturn Blade 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). |

The 1-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 SuperBlade® Chassis Management Module 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 link aggregation (static), VLAN support, and Jumbo Frame support, the switch provides a connection between the Ethernet controller integrated on the mainboard and external Ethernet systems.
The 1/10-Gigabit Ethernet layer 2/3 Switch module (part ID SBM-GEM-X2C) offers advanced switching features and connection to 10-Gigabit Ethernet networks. Internally it uses the same 1-Gb/s downlink ports as the SBM-GEM-001 for connection to the SuperBlade® LAN interfaces. Externally it provides up to three 10-Gb/s uplink connections (two with a CX4 connector which are stackable and one SFP+) and two 1Gb/s uplink connections (RJ45). It 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. In addition to the Web-based GUI, it offers a CLI for flexibility in management and control of single or multiple switch networks. |

The 1-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).
The 10-Gigabit Ethernet Pass-through Module (part ID SBM-XEM-002) is also a non-configurable pass through module. It provides fourteen 10-Gb/s external uplink (SFP+) ports and fourteen internal 10-Gb/s downlink ports for the SuperBlade®'s LAN interfaces. Internal links are provided by the use of a mezzanine card (AOC-IBH-003) with 10-Gigabit Ethernet support capability (see AOC-IBH-003 item description below). |

| 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-Gbps). |

| InfiniBand Mezanine 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, AOC-IBH-002, AOC-IBH-003 and AOC-IBH-XDD mezzanine cards provide this 20-Gbps connectivity (4x DDR) through the backplane to the InfiniBand switch module. The AOC-IBH-003 and AOC-IBH-XDD can alternatively be used for 10-Gbps Ethernet connectivity when used in concert with the SBM-XEM-002 10-Gbps Pass-through module. |
