Disk I/O for Exchange 2010
Posted on 2011-10-06
I am looking at creating a disaster recovery site for my Exchange 2010 implementation. The issue that I am running into is picking out a RAID that will be able to handle the I/O from Exchange 2010. What is the best way to determine how much I/O is being generated by my current system? I have a couple of different arrays that I am looking at and the only real difference that I am seeing between is cost and I/O capability. I want to make sure that I am picking the correct system to handle the I/O. I know in UNIX I would run iostat –xtc 15 > /tmp/io.txt and looking at the information in there, but there are a lot more options in Windows 2008 Enterprise Edition SP2 for disk I/O. Which counter/counters are going to provide me the best information?
