This chapter provides an overview of the Sun Blade 6048 InfiniBand QDR Switched Network Express Module (IB-QNEM).
This chapter includes the following sections:
You can order additional Sun Blade 6048 InfiniBand QDR Switched Network Express Modules from Sun Microsystems using the following Marketing part number: X5500A-Z.
The Sun Blade 6048 InfiniBand QDR Switched Network Express Module (FIGURE 1-1) has the following features:
2 I4 on-board switches, both providing 2 Infiniband ports for each slot in a Sun Blade 6048 modular system shelf
2 passthrough Gigabit Ethernet ports for each slot of IB-QNEM’s respective a Sun Blade 6048 modular system shelf
Each IB-QNEM InfiniBand port can provide full-duplex data transfers of up to 40 Gbps (QDR)
Each InfiniBand port is backward compatible with 20-Gbps (DDR) and 10-Gbps (SDR) devices
The IB-QNEM logically installs inthe NEM-1 slot of a Sun Blade 6048 modular system shelf, but occupies both NEM slots due to physical form factor
Up to 12 blade servers can connect to a single IB-QNEM. Each blade server is connected to the IB-QNEM through two 4x QDR IB interfaces and two 1 GbE interface
TABLE 1-1 lists additional features of the Sun IB-QNEM.

Sun Blade Server Module |
For information about the supported operating systems for a server module, go to: http://www.sun.com/servers/blades/os.jsp
The IB-QNEM provides a standard set of status indicators, buttons, and ports on the back panel. FIGURE 1-2 shows the back panel.
See TABLE 1-3 for a description of the components.
The IB-QNEM has two 36-port InfiniBand switches, I4A and I4B. Each port is capable of negotiating with a peer node up to 4x QDR speed. Each switch I4 device has 15 ports connected to 5 CXP external IB connectors. I4A has 12 ports connected to the two 4x ports from iTRAC 0 through 5 and I4B has 12 ports connected from iTRAC 6 through 11. The remaining nine ports are intralink connections between the two I4 devices.
TABLE 1-4 and TABLE 1-5 list the specifications for the IB-QNEM in the Sun Blade 6048 Series Modular System.

The regulatory compliance certifications of the Sun Blade 6048 Modular System cover the Sun Blade 6048 InfiniBand QDR Switched Network Express Module as an installed component.
To comply with legal EMI emissions regulations, the Sun Blade 6048 Modular Server must be provided with either the standard door or cooling rear door assembly when used with the Sun Blade 6048 InfiniBand QDR Switched Network Express Module. The rear door should remain closed during normal operation and opened only during product servicing or when power is removed from the product.
