Intel® Server Board S2600CP Functional Architecture Intel® Server Board S2600CP and Server System P4000CP TPS The Intel® C600 chipset in the Intel® Server Board S2600CP provide a connection point between various I/O components and Intel® Xeon E5-2600 processors, which includes the following core platform functions:  Digital Media Interface (DMI)  PCI Express* Interface  Serial ATA (SATA) Controller  Serial Attached SCSI (SAS)/SATA Controller (S2600CP2/S2600CP4 only)  AHCI  Rapid Storage Technology  PCI Interface  Low Pin Count (LPC) Interface  Serial Peripheral Interface (SPI)  Compatibility Modules (DMA Controller, Timer/Counters, Interrupt Controller)  Advanced Programmable Interrupt Controller (APIC)  Universal Serial Bus (USB) Controllers  Gigabit Ethernet Controller  RTC  GPIO  Enhanced Power Management  Intel® Active Management Technology (Intel® AMT)  Manageability  System Management Bus (SMBus* 2.0)  Virtualization Technology for Directed I/O (Intel® VT-d)  KVM/Serial Over LAN (SOL) Function 4.3.1 Digital Media Interface (DMI) Digital Media Interface (DMI) is the chip-to-chip connection between the processor and C600 chipset. This high-speed interface integrates advanced priority-based servicing allowing for concurrent traffic and true isochronous transfer capabilities. Base functionality is completely software-transparent, permitting current and legacy software to operate normally. 4.3.2 PCI Express* Interface The C600 chipset provides up to 8 PCI Express Root Ports, supporting the PCI Express Base Specification, Revision 2.0. Each Root Port x1 lane supports up to 5 Gb/s bandwidth in each direction (10 Gb/s concurrent). PCI Express Root Ports 1-4 or Ports 5-8 can independently be configured to support four x1s, two x2s, one x2 and two x1s, or one x4 port widths. 4.3.3 Serial ATA (SATA) Controller The C600 chipset has two integrated SATA host controllers that support independent DMA operation on up to six ports and supports data transfer rates of up to 6.0 Gb/s (600 MB/s) on up to two ports (Port 0 and 1 Only) while all ports support rates up to 3.0 Gb/s (300 MB/s) and up to 1.5 Gb/s (150 MB/s). The SATA controller contains two modes of operation - a legacy mode 40 Revision 1.2 Intel order number G26942-003
