Re: Is still recommended to not share File and Block LUNs in the same POOL in Unity?

Dell EMC recommends to use minimum number of pools to reduce complexity and increases flexibility. Respect to File & Block, I never come across recommendation from Dell EMC. But I would suggest to go for Unified pool because the system designed accordingly to meet the requirements. And I'd suggest you to get in touch with Dell EMC Engineer, based on your environment File & Block workload & IO profiles they can recommend which option you may choose.
