Storage and Regen buffer sizes

Question

What is the formula for calculating the sizes of the storage and regeneration buffers on a Gen 4 Centera? Do these sizes change depending on if the system is set up CPM or CPP?

AndrewEMC · Answer

One disk per cube is suffice. CPM or CPP is irrelevant. It's based upon mirror group. So if you pick one disk for regeneration buffer effectively it reserve one disk on even power rail and one disk on odd power rail
