5.6 Speed Burst Card
To increase performance in a 2-socket HX5 server (that is, with two processors installed),
install the IBM HX5 1-Node Speed Burst Card. The 1-Node Speed Burst Card takes the QPI
links that typically are used for scaling two HX5 2-socket blades and routes them back to the
processors on the same blade. Table 5-7 lists the ordering information.

Figure 5-5 on page 186 shows a block diagram of the Speed Burst Card attachment to
the system.

Speed Burst Card: The Speed Burst Card is not required for an HX5 with only one
processor installed. It is also not needed for a 2-node configuration (a separate card is
available for a 2-node configuration, as described in 5.8, “Scalability” on page 188).
