I have a couple questions regarding growing one of my aggregates w/ additional array LUNs. I'm have created a 12 disk RAID group on our EMC and I need to know how large to make the LUN to present to our V-3170? Is there a limitation on how large the LUN can be?
My biggest concern is making sure I maintain performance and I think 12 spindles should cover it, I just want to make sure I present it to the V-Series in the manner of getting peak performance and additional space.
See the v-series implementation guide for your array. Attached is he EMC CX guide from the now site. Page 10 gives the minimum and maximum sizes for luns. The sizes are specific depending on the back-end array you are using.
