Figure 6 illustrates the same cell board utilizing HP’s new mx2 Dual-Processor Modules. Note that the only difference between this figure and Figure 5 is that now each mx2 Dual-Processor Module can support two CPU cores.

Memory The first release of the HP Integrity Superdome will support 128-megabit and 256-megabit SDRAM.
Integrity Superdome servers use Intel Itanium 2 processors or mx2 Dual-Processor Modules. The mx2 Dual-Processor Module supports two Intel Itanium 2 processors with a large shared 32 MB L4 cache in the same cell board socket that is used for a single Intel Itanium 2 processor. This HP innovation offers up to twice the performance density of the previous Integrity Superdome servers.
