Dell Storage with Microsoft Storage Spaces Best Practices Guide

Cluster shared volumes

Dell recommends that no CSVs be greater than 10 TB, to ensure efficient failover from one node to another.

You must have one cluster-shared volume (CSV) for every VD. You should add CSVs in multiples of the cluster nodes to enable the CSVs to load balance across the cluster. For example, if you have a 2x2 configuration, which has two storage nodes, you should create CSVs in multiples of two (for example, 2, 4, 6, and 8 CSVs). If you have a 4x4 configuration, which has four storage nodes, create CSVs in multiples of 4 (for example 4, 8, 12, and 16 CSVs).

To support the addition of cluster nodes in the future, Dell recommends that you have the quantity of CSV to be at least twice the number of cluster nodes. For example, a 2x2 configuration should have four CSVs.
