Right. That looks to be RAM based, which means $$$$ compared to NAND, so that's not going to breakout of a server niche. I imagine the latency is the device latency not the system latency. By the time you send the request through the fibrechannel stack and get the block back it's gonna be much closer to 100 microseconds. It's that OS visible latency that you've got to design to. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
