One kind is applied in the road server PCH configuration structures of purley platforms eight
Technical field
Server field is the utility model is related to, more particularly to one kind is applied and matched somebody with somebody in the road server PCH of purley platforms eight
Put structure.
Background technology
The PCH for the Purley platforms compatibility that Intel is newly released is LBG (Lewiburg) series, except being opened with traditional PCH
Outside machine and external I/O function, inside is also integrated with 10G networks can be directly by external I/O to interchanger, while also has
QAT (Quick Assist Technology) function, data can be encrypted and accelerate to play the mesh to processor Reduction of Students' Study Load
's.The signal that new LBG interacts with CPU does not only have DMI, while also X16 PCIE3.0 and optional X8PCIE 3.0.This
LBG compared with traditional PCH, itself also corresponds to a PCIE device in fact from the point of view of sample, and the FW of the PCIE device is equally existed
In Flash and BIOS is in different regions.
In high-end server design, four calculate nodes realize the design of 8 road servers by backboard QPI interconnections.Often
Individual calculate node has a PCH to be responsible for switching on and shutting down and just determined to external expansion IO, such PCH quantity by the quantity of calculate node
It is fixed.When 8 tunnel systems are opened, it is only necessary to a PCH, can so cause the waste of PCH resources on other computing board, only 8 tunnels
When being downgraded to 2 tunnel, the PCH of each calculate node can just make full use of.

Operator node, 2,4,8 tunnels freely can be switched to by switch.In the entire system, if user is it is desirable that 2 tunnels service
Device, then by the shared signal of each calculate node of switch cutoff, make the work of each calculate node independence, so each meter
The PCH modules of operator node are normal mode of operation.When user prepare open 8 road servers in, by switch make all meters
Operator node shares signal communication, while the PCH modules of only first calculate node are responsible for the start sequential of whole system, then
BIOS information is read to initialize the equipment of system.The PCH modules disabling of other three calculate nodes falls DMI functions, only
EPO (Endpoint Only) pattern of PCH modules is operated in, is no longer responsible for starting shooting sequential and reads BIOS, only in start
FW needed for loading 10G networks and QAT functions.So all PCH module resources can make full use of in the entire system, together
When add the quantity of external I/O device, lift the performance of whole system.
