План вебинара:
##Что такое Storage Spaces Direct?
##Сценарии использования Storage Spaces.
##Описание минимальных требований для Storage Spaces.
##Как настроить Windows Server 2016 Spaces Direct для работы с локальными дисками сервера?
##Что такое Storage Replica?
##Разница подходов синхронной и асинхронной репликации.
##Какие технологии репликации для каких задач использовать (DFS-R, Hyper-V Repica, SQL AlwaysOn, Exchange DAG) - и как это комбинируется с новыми возможностями Windows Server 2016?
##Что такое ReFS и чем она отличается в Server 2016 от предыдущих изданий ОС?
##Что даёт использование ReFS для виртуальных машин Hyper-V. Сценарии и возможности.
##Общие изменения Storage технологий в Windows Server 2016.
