SERIES3800/S120T (7045A-C3/7045A-CT) User's Manual
1-2 Serverboard Features
At the heart of the SERIES3800/S120T (7045A-C3/7045A-CT) lies the X7DCA-3/ X7DCA-i, a dual processor serverboard based on the Intel 5100 chipset and designed to provide maximum performance. Below are the main features of the X7DCA-3/X7DCA-i. (See Figure 1-1 for a block diagram of the chipset).
Processors
The X7DCA-3/X7DCA-i supports single or dual LGA771 type Intel Xeon 5400/5300/5200/5100 Series processors at a FSB speed of 1333/1066 MHz. Please refer to the serverboard description pages on our web site for a complete listing of supported processors (www.supermicro.com).
Memory
The X7DCA-3/X7DCA-i has six 240-pin DIMM slots that can support up to 32 GB of ECC DDR2-667/533 SDRAM. The memory operates in an interleaved configuration and requires requires modules of the same size and speed to be installed two at a time. See Chapter 5 Section 5 for details.
Onboard SAS
An onboard LSI 1068 SAS controller is integrated into the X7DCA-3 (only), which supports eight SAS hard drives. The SAS drives are connected to a backplane that provides power, bus termination and configuration settings. These SAS drives are hot-swappable units and support RAID levels 0, 1, 10 and (with iButton) 5.
Note: The operating system you use must have RAID support to enable the hot- swap capability and RAID function of the SAS drives.
Serial ATA
A Serial ATA controller is integrated into the ICH9 (South Bridge) portion of the chipset to provide a six-port 3 Gb/s SATA subsystem, which is RAID 0, 1, 10 and 5 supported. The SATA drives are hot-swappable units.
Note: The operating system you use must have RAID support to enable the hot- swap capability and RAID function of the SATA drives.
PCI Expansion Slots
The X7DCA-3/X7DCA-i has one PCI-Express x16 slot, one PCI-Express x4 (in
ax16 slot), two 64-bit 133/100 MHz PCI-X slots, two PCI 33 MHz slots and an IPMI slot.
