Just a quick update - I doubled checked with engineering about the raid group statistic and they come from the disks not the LUNs. So the stats on the LUNs (due to caching) can be different than what you see at the RG.  glen
Hi all,  I've been mucking about with Navisphere analyzer for a bit and I came across something I found to be odd. [URL]#5536050897680055426  When you look at the IOPS for LUN 520 (the linegraph with the dot on it) it shows quite large fluctuations (averaging 1200 IOPS) over time. But when you look at the total IOPS for the raidgroup containing this LUN and several others, the IOPS count is much lower. On the RG the average is a lot less (~100 IOPS).  I was wondering if anyone had a really good explanation for this seeing as I don't seem to understand it, no matter how many whitepapers I've been through.  Thanks in advance. Christoffer
