This Gauge32 reports the system's current capacity utilization as a percentage, tracked under the 'soft' utilization object alongside its 'hard' counterpart. On an IBM XIV system, which distinguishes soft (logical/thin-provisioned) capacity from hard (physical) capacity, this value gives an admin visibility into how full the logical capacity pool is running; this soft/hard distinction is an illustrative interpretation, since the source description text doesn't spell it out directly. An admin seeing xivUtilizationSoft climb toward 90% would plan to add capacity or reduce thin-provisioning overcommit before space runs out.
