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.
