We asked several manufacturers of motherboards destined for servers built around the Opteron in order to know how Nvidia’s nForce Pro is doing in this area. Their response was pretty much the same and similar to that given by Gigabyte : "Most of the market is dominated by Broadcom, which has the confidence of the professional sector, and Nvidia chipsets are left with a part of the entry level".
Note that Gigabyte now offers with its motherboards based on Broadcom chipsets a small optional card which has SAS (Serial Attached SCSI) support, the "new SCSI".
When we asked different actors on the motherboard server market about the introduction of SiS, we got big smiles. If Nvidia is already thwarted in the entry level domain, what do they do with SiS ?
