Жесткий резерв - если включим минимальное резервирование 20%
Доступная память указана по выделенному объему (используется меньше, доступно больше)
Емкость HA вычитается из Capacity, если нет хостов в Maintenance, в противном случае вычитается ресурс хостов в Maintenance. За объем для HA принимается размер наибольшего хоста в кластере по каждому ресурсу (поэтому при выводе в Maintenance расчетная емкость может временно увеличиться)

* CPU GHz provision rate % - отношение зарезервированной частоты (с учетом 20% резерва по умолчанию) к наличной частоте процессоров
* Для средней ВМ указана аллоцированная память, а в скобках - используемая
