We are currently working with a Dell reseller on a possible Compellent purchase and would appreciate any thoughts or opinions on the question below related to the sizing of the Compellent array.
We are curretly working with a Dell Reseller on a possible Compellent purchase (moving from existing Equallogic arrays) and the reseller has not (and is not) recommending the use of the DPACK analysis tool that Dell typically recommends for gathering usage data and sizing the tiers of the array. We would appreciate thoughts or opinions on sizing of the arrays and any yes/no recommendations on us mandating the DPACK analysis be done. Everyone we have spoken with who is an existing Compellent customer has indicated this was a mandatory step and not getting this recommendation from the reseller is concerning to us as we fear it may lead to incorrect sizing of the tiers and spindle counts.
Thanks for any input or recommendations.
