If you recall Neil stated that CPU burn shouldn't be an issue when using mdraid linear over 16 mdraid 10 arrays in the proposed system. As long as the kernel somewhat evenly distributes IO steams amongst multiple cores I'm inclined to agree with Neil. Note that the application in this case, the NFS server, is threaded kernel code, and thus very fast and scalable across all CPUs. By design, all of the performance critical code in this system runs in kernel space. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
