<< LU with host channel adapters? Isn't that something that Q is - or should - be doing? If LU is doing it, does it mean that Q isn't?>>
I read the info in the article a little differently. From the EE Times article you included: "Intel Corp. will offer three initial components to support Infiniband — a host channel adapter, switching engine and target channel adapter — while Lucent Technologies Inc.'s microelectronics group will sample a four-channel serializer/deserializer device"
I read this as Intel will offer the host channel adapters, with Lucent offering the SER/DES. A year and a half ago Cal Nelson said the only remaining component for them to integrate into their FC switching ASIC was the serializer/deserializer. I don't know that this function is included in Itasca, but I would guess it is.
If it is included in Itasca, it may also be included in the ASIC used in the InfiniBand switches. If so I wonder if the Lucent chip is useful to QLogic? Anyone know?
Also, this link posted by a reliable poster includes the following information Message 14266347 : "Intel's InfiniBand chips will initially be aimed at low-end systems using the slower, cheaper and simper "1X" version of InfiniBand, which offers a connection speed of 2.5 gbps (gigabits per second). IBM chips will start with more expensive "4X" designs, four times the speed.
Lucent's chips target both the 1X and 4X standards, but the company said its models use two-thirds the power of competing chips. That's important for data centers packed with thousands of chips that must be kept cool."
They may serve the same function for different applications.
