13. Балансировка нагрузки и отказоустойчивость в Hyper-V
12/30/2017 8:55 AM
Балансировка нагрузки и отказоустойчивость в Hyper-V
Наиболее востребованная функция
Не все решения по балансировке и отказоустойчивости работают в Hyper-V
MAC-адрес больше не используется в виртуальном свиче
Первое обращение – к вендору!
Microsoft официально НЕ поддерживает NIC Teaming
NIC Teaming реализуется производителем «железа»

14. NIC Teaming Технология имеет несколько названий:
Ethernet bonding
EtherChannel
NIC bonding
Network Fault Tolerance
Trunking и т.д.
Но официальное название – IEEE 802.1AX-2008
Или просто Link Aggregation
Реализуется производителями оборудования на уровне специального ПО (драйвера)

NIC Teaming
Суть механизма в объединении нескольких NIC в «связку» (bond)
Технология позволяет:
Создавать отказоустойчивые сетевые соединения
Увеличивать пропускную способность сети
Создавать собственные алгоритмы балансировки
Минусы технологии:
Требуется свич/маршрутизатор с поддержкой протокола LACP (Link Aggregation Control Protocol)
Поломка свича приведет к потере отказоустойчивости
