S UPER S ERVER 6010L Manual 1-3 Mainboard Features At the heart of the SuperServer 6010L lies the 370DLR+, a dual processor motherboard designed to provide maximum performance. Below are the main features of the 370DLR+. Chipset The 370DLR+ is based on the ServerWorks ServerSet TM III LE chipset, which is a high-performance core logic chipset that consists of a North Bridge and a South Bridge. The North Bridge includes an integrated main memory subsystem and a dual channel PCI bus that bridges the processor bus to a 64-bit PCI bus and a 32-bit PCI bus. The North Bridge also packs and unpacks data for PCI accesses, which reserves more processor bandwidth for multiprocessor motherboards.
The South Bridge provides various integrated functions, including the PCI to ISA bridge and support for UDMA33, security (passwords and system pro- tection), Plug & Play, USBs, power management, interrupt controllers and the SMBus. Processors The 370DLR+ supports single or dual 370-pin Pentium III FCPGA 500 MHz-1 GHz processors with a 133 or 100 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 370DLR+ has 4 DIMM slots that can support up to 4 GB of ECC regis- tered PC133 and PC100 SDRAM. Module sizes of 128MB, 256MB, 512MB and 1 GB may be used to populate the DIMM slots.
The DIMM slots are situated at a 25 degree angle to create a low profile and to promote effi- cient airflow through the chassis. 1-4
