This week ASRock are launching a high/low combination of motherboards for Haswell. The first one is going to be one of the wildest designs on the Z87 platform, using an LSI 3008 chip combined with a 3X24R expander to provide sixteen SAS-3/SATA 6 Gbps alongside the six SATA 6 Gbps ports already provided by the chipset, giving 22 total. We actually saw this motherboard at Computex earlier in the year, all hooked up: At the time, we postulated on the PCIe lane allocation, as ASRock had said that this was possible with only one PLX 8747 switch, whereas on the Z77 Extreme11 they had used two. It all comes down to the LSI 3008, which requires eight PCIe lanes by itself. ...
