This read-only Gauge32 field is the 'kernelMemTotalMin' property of the 'FexSystemStatsHist' managed object in Cisco UCS Manager's equipment-inventory schema recording the lowest total-memory figure reached during the interval this archived sample covers. As with the Max variant, this is a historical consistency check rather than an operational trend, confirming the FEX's total kernel memory was stable during that interval. A discrepancy between an archived KernelMemTotalMin and the surrounding samples' baseline would point to an unplanned reload captured in that stored row.
