Those are easy to get rid of.
Start at the first available slot on each BUS and evenly balance the available Flash drives across the first slots of the first enclosure of each bus beginning with the FAST Cache drives.
When there are different drives of the same type in a VNX, but different speeds, form factors or capacities, then these should ideally be placed on different buses.
While all un-configured drives in the VNX2 Array will be available to be used as a Hot Spare, a specific set of rules are used to determine the most suitable drive to use as a replacement for a failed drive: All suitable drive types are gathered.
Which of the suitable drives are contained within the same bus as the failing drive. Following on from the Bus query MCx will then select a drive of the same size or if none available then a larger drive will be chosen.
This is another new feature where MCx will analyse the results of the previous steps to check if the Enclosure that contains the actual Failing drive has a suitable replacement within the DAE itself.
