1-2 Mainboard Features
At the heart of the SuperServer 6021i lies the P3TDDE, a dual processor moth-
erboard designed to provide maximum performance. Below are the main features
of the P3TDDE.
Chipset
The P3TDDE is based on the VIA Apollo Pro 266T chipset, which is a high-
performance core logic chipset that consists of a North Bridge and a South
Bridge. See Figure 1-1 for a block diagram of the chipset.
The North Bridge includes an integrated main memory subsystem and a dual
channel PCI bus that bridges the processor bus to a 32-bit PCI bus. The
North Bridge also packs and unpacks data for PCI accesses, which re-
serves more processor bandwidth for the multiprocessor motherboard.
The South Bridge provides various integrated functions, including the PCI to
ISA bridge and support for UDMA100, security (passwords and system
protection), Plug & Play, USBs, power management, interrupt controllers
and the SMBus.
Processors
The P3TDDE supports single or dual Pentium III Tualatin 500 MHz - 1.40 GHz
processors with a 100 or 133 MHz FSB. Please refer to the support section
of our web site for a complete listing of supported processors: < http://
www.supermicro.com/TechSupport.htm >.
Memory
The P3TDDE has 4 DIMM slots that can support up to 4 GB of ECC registered
PC133 and PC100 SDRAM. Module sizes of 128MB, 256MB, 512MB and 1
GB may be used to populate the DIMM slots.
PCI Expansion Slots
The P3TDDE has five 32-bit 33 MHz PCI slots.
