  +[NOTE]
  +====
  +Soft eviction usage is more common when you are targeting a certain level of
  +utilization, but can tolerate temporary spikes. It is recommended
  +that the soft eviction threshold is always less than the hard eviction
  +threshold, but the time period is operator specific. The system reservation
  +should also cover the soft eviction threshold.
  +====
  +
  +Implicit in this configuration is the understanding that `system-reserved`
   should include the amount of memory covered by the eviction threshold.
   
   To reach that capacity, either some pod is using more than its request, or the
  -system is using more than *1Gi*.
  +system is using more than `1Gi`.
  +
  +If a node has 10 Gi of capacity, and you want to reserve 10% of that capacity for
  +the system daemons, do the following:
  +
  +----
  +capacity = 10 Gi
  +system-reserved = 10 Gi * .01 = 1 Gi
  +----
  +
  +The node allocatable value in this setting becomes:
  +
  +----
  +allocatable = capacity - system-reserved = 9 Gi
  +----
  +
  +This means by default, the scheduler will schedule pods that request 9 Gi of
  +memory to that node.
  +
  +If you want to turn on eviction so that eviction is triggered when the node
  +observes that available memory falls below 10% of capacity for 30 seconds, or
  +immediately when it falls below 5% of capacity, you need the scheduler to see
  +allocatable as 8Gi. Therefore, ensure your system reservation covers the greater
  +of your eviction thresholds.
  +
  +----
  +capacity = 10 Gi
  +eviction-threshold = 10 Gi * .05 = .5 Gi
  +system-reserved = (10Gi * .01) + eviction-threshold = 1.5 Gi
  +allocatable = capacity - system-reserved = 8.5 Gi
  +----
  +
  +You must set `system-reserved` equal to the amount of resource you want to
  +reserve for system-daemons, plus the amount of resource you want to reserve
  +before triggering evictions.
   
   This configuration ensures that the scheduler does not place pods on a node that
   immediately induce memory pressure and trigger eviction assuming those pods use
   less than their configured request.

positive.code: 
  Consider the following scenario:
  
  * Node memory capacity of *10Gi*.
  * Operator wants to reserve 10 percent of memory capacity for system daemons
  (kernel, node, etc.).
  * Operator wants to evict pods at 95 percent memory utilization to reduce
  thrashing and incidence of system OOM.
  
  To facilitate this scenario, the

  When the above is set the node continues to report node status updates at the
  frequency specified by the `node-status-update-frequency` argument, which
  defaults to `10s`.
