Processor Mounting Rule

It is required to embed processors for processor memory modules.
 It is required to that processor memory modules are mounted in a server, connected to IOH#1
or -IOH#3 having Management Module (MGM) that controls server configuration, handles
failures, etc.

With A1080a-S/A1040a model, 1, 2, 3, and 4 processors can be embedded to the server 1.

With A1080a-D model, 1, 2, 3, and 4 processors can be embedded both to the server 1 and 2.
 With A1080a-E model, 8 processors can be embedded to a server.
The following shows the connection of processor memory modules (PMMs) for A1080a-S model
and A1040a model. All processor memory modules can be connected one another. Some I/O
controllers (IOHs) cannot be connected to processor memory modules directly, but can be
connected via other processor modules.
For A1080a-S,A1040a
Example) In the four-processor memory module configuration, PMM1 and IOH2 cannot be
connected directly as shown below. However, a PCI card under IOH2 can be used via
PMM2 or PMM4.
For example, the PCI card under IOH2 can be used via PMM4 even in the case of
failure on PMM2.
* PMMx is an abbreviation of a processor memory module.
* IOHx is an abbreviation of an I/O hub.
* ICH is an abbreviation of an I/O control hub.
