A stripe group is a collection of LUNs (typically disks or arrays) across which data is striped. Each stripe group also has a number of associated attributes, including affinity and exclusivity.

An affinity is used to steer the allocation of a file’s data onto a set of stripe groups. Affinities are referenced by their name, which may be up to eight characters long. An affinity may be assigned to a set of stripe groups, representing a named pool of space, and to a file or directory, representing the space from which space should be allocated for that file (or files created within the directory).
