FYI, it was an integrator on this list that turned me on to the SuperMicro H8SSL-i after I mentioned the Broadcom ServerWorks HT1000 chipset. Homepage for the SuperMicro H8SSL-i: http://www.supermicro.com/Aplus/motherboard/Opteron/HT1000/H8SSL-i.cfm Manual for the SuperMicro H8SSL-i: http://www.supermicro.com/manuals/motherboard/HT1000/MNL-H8SSL-i.pdf One thing that confuses me is the block diagram on page 1-8 (PDF page 14). It says the dual-GbE LAN (provided by the BCM5704*1* according to the same manual, page 1-8, PDF page 13) is on the PCI-X bus along with the slot, but that it runs at 133MHz. I was not aware that PCI-X [1.0] was capable of running more than 1 device at 133MHz. It could be that it slows down to 100MHz if you put in a PCI-X card. Of course, if you put in a legacy 64-bit@66MHz 3.3V PCI card like a $125 3Ware Escalade 8006-2 (2-channel, true ASIC hardware SATA RAID) or $250 3Ware Escalade 8506-4 (4-channel), then it will run at 66MHz (should auto-detect, although jukmper JPXA1 lets you manually set both options of PCI-X 66MHz or legacy PCI 66MHz). But that is still 0.5GBps for NIC and storage -- 4x standard PCI or a PCIe x1 channel (although the PCIe x1 is bi-directional). According to the BCM5704*1* product brief, each NIC has its own RISC off-loading processor 16KiB of SRAM as well as dual 64KiB RAM packet buffer. You might be eyeing the $50-60 SysKonnect SK-9E21D*2* PCIe x1 NIC, it has a 48KiB RAM packet buffer (no RISC+SRAM off-load engine -- just a "large send off-load"). Even the $125-150+, server-designed PCIe x1 SK-9E21 or PCIe x4 SK-9E21 (PCI-X equivalent SK-9S21 and SK-9S22, respectively) doesn't seem to offer any off-load other than "large send off-load" (can't tell how good, the manual is in French or German and doesn't make any mention of SRAM), only 2x the RAM (per port), 96KiB. *1* Broadcom BCM5704 Product Brief (first page): http://www.broadcom.com/collateral/pb/5704C-PB04-R.pdf *2* SysKonnect SK-9E21D Manual (page 41, PDF page 39): http://www.skd.de/e_en/products/adapters/pcie_desktop/sk-9exxd/docu/Sk-9E21D_E.pdf Some resellers are claiming they are selling the SuperMicro H8SSL-i, although I thought SuperMicro was against that, and only provided it for resellers (largely because of their relationship with Intel).
