Processor Sockets
Each Intel Itanium 2 processor plugs into a 700-pin Zero Insertion Force (ZIF) socket. Each
processor is powered by a 12-V power pod located adjacent to the processor on the main board.
Attached to the top of each processor is a heat sink that dissipates thermal energy.
Memory Subsystem
The basic architecture of the memory subsystem is as follows:
•
The DIMMs reside on the main board, between the PCI riser assembly and the chassis.
•
Four Rambus channels run from the Scalable Node Controller (SNC) to each of the four
Memory Repeater Hubs (MRH-D).
•
There is one MRH-D device per Rambus channel.
•
Each MRH-D supports two DDR branch channels.
•
Each DDR branch channel supports two 184-pin DDR DIMMs.
•
The server system includes eight DIMM connectors in two rows.
•
Each row of DIMM sockets supports four DDR DIMMs, one channel of each MRH-D, which
collectively make up a cache line.
The DIMM socket locations are shown in Figure 17.
