Abstract
A data storage node includes a plurality of compute nodes that allocate portions of local memory to a shared cache. The shared cache is configured with mirrored and non-mirrored segments. The mirrored and non-mirrored segments are separately configured with pools of data slots. Within each segment, each pool is associated with same-size data slots that differ in size relative to the data slots of other pools. The sizes of the pools in each segment are adjusted to minimize cache loss, where cache loss is the difference between the amount of shared cache used to service IOs and the minimum amount required for servicing the IOs.
