This is the free-text description of the ComputeConnPolicy, per its descr property. An admin uses this field to record why a particular connectivity policy exists — e.g. which class of workload requires it — so that months later, someone reviewing service profiles understands the intent behind assigning this policy rather than a default one. A descr reading 'Requires full SIOC redundancy for production DB blades' documents the operational reasoning behind a stricter policy setting.
