1-2 Processor/PCH Platform Overview
Built upon the functionality and capability of the Intel E7 series processor(s) and
the 602J PCH, the X10QBi system provides support for quad-processor-based
HPC/Cluster/Database server platforms.
With the Intel QuickPath interconnect (QPI) controller built in, the E7 series proces-
sor offers a point-to-point system interconnect interface, greatly enhancing system
performance by utilizing serial link interconnections, which allows for increased
bandwidth and scalability.
The 602J PCH provides an Interface between the QPI-based processor and
PCI-Express components. Each processor supports full-width, bidirectional inter-
connects at the speeds of up to 9.6 GT/s. Each QPI link consists of 20 pairs of
unidirectional differential lanes for data transmission in addition to a differential
forwarding clock. The x16 PCI Express Gen 3 connections can also be cong-
ured as x8, x4, and x2 links to comply with the PCI-E Base Specication, Rev.
2.0. These PCI-E Gen 3 lanes support peer-to-peer read-and-write transactions.
The 602J PCH also offers a wide range of ESI, Intel® I/OAT Gen 3, Intel VT-d, and
RAS (Reliability, Availability and Serviceability) support. The features supported
include memory interface ECC, x4/x8 Single Device Data Correction (SDDC),
Flow-through CRC (Cyclic Redundancy Check), parity protection, out-of-band
register access via the SMBus, and memory mirroring for data integrity.
Main Features of the 602J PCH Chip
• Full-connectivity (with four Intel® QuickPath Interconnects and up to ten cores
in each socket with 24MB of shared last level (L3) cache supported)
• CPU-integrated memory controller with support of the following:
• DDR3 ECC RDIMM/LRDIMM memory with speeds of up to 1600 MHz when
the X10QBi-MEM1 memory card is used in the system, or
• DDR4 ECC RDIMM/LRDIMM memory with speeds of up to 1866 MHz when
the X10QBi-MEM2 memory card is used in the system
• Virtualization Technology
• 44-bit physical address and 48-bit virtual address supported
