SUPERSERVER 6021H Manual 1-3 Mainboard Features At the heart of the SuperServer 6021H lies the P3TDER, a dual processor motherboard designed to provide maximum performance. The following are the main features of the P3TDER. Chipset The P3TDER is based on ServerWorks ServerSet TM III HE-SL 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 UDMA100, security (passwords and system protection), Plug & Play, USBs, power management, interrupt controllers and the SMBus. Processors The P3TDER supports single or dual Intel Pentium III 500 MHz-1.50 GHz 512K L2 cache processors at either a 100 or 133 MHz FSB. Please refer to the support section of our web site for a complete listing of supported proces- sors (http://www.supermicro.com/TechSupport.htm). Memory The P3TDER 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. Onboard SCSI Onboard SCSI is provided with an Adaptec AIC-7899W SCSI controller chip, which supports dual channel, Ultra160 (320 optional) SCSI at a burst throughput rate of 160 MB/sec. The P3TDER provides two SCSI ports. 1-4
