I have a question about the passive copy IO in Exchange 2010. Early in the blog you state that the disk IOPs for the passive copy were underutilized but later state that the IOPS for a passive copy was equal to the IOPs for a active copy in exchange 2010. How are the disks underutilized in terms of IOPS between the active and passive copies if the IOPS is the same? Am I misunderstanding something?

Great post Scott and I really enjoyed your session on this topic at MEC as well.

One thing I was curious about was where the Exchange Team got the 20MB/sec number from for reseeding. I'm not questioning it but am genuinely curious what factors and areas of analysis were considered to come to that number. Thanks.
