It is OK to have slightly different TDAT sizes in the pool to accommodate various internal devices such as SFS, Vault, gatekeepers, etc.
Hi --    We have a bin for a new vmax and i noticed two different size TDATs that were created to maximize the use of the spindles.  I beleive the offset was created to include gatekeepers.   My question -  Is it Ok to run two different size TDATS in a thin pool?  
Different size TDATS in Thin Pool for max capacity config
