@markhahn: it seems that way... QLogic will remain the only non-Mellanox Silicon with its TrueScale ASIC. One difference is QLogic also has silicon for converged ethernet and fiber channel ideal for FCoE, whereas, Mellanox makes PHyX, a much broader multi-protocol 10GigE PHY to literally connects all forms of physical layers XAUI , XFI, SFI or 10GBASE-KR, 10GbaseT, etc.
Interesting consolidation in the IB marketplace with Mellanox acquiring Voltaire. Frankly, Mellanox may do better in the multi protocol products than the core InfiniBand products now that 10G products are becoming mainstream and 40G/100G products are off the drawing board.
at least to Qlogic, this is interesting. can't make any real difference to the rest of IB's so-called ecosystem, since Mellanox produced the heart of Voltaire's products anyway.
is Qlogic's Infinipath NIC the only non-Mellanox chip keeping IB from being entirely single-source?
