Вопрос, может ктото внести ясность?
Согласно этой статьи kb.vmware.com/s/article/1003469
esxi работает с блоками до 32767 KB я правильно понимаю что это 32 мебагайта?
Если да, то я не понимаю тогда какой блок при создании LUN выберать? (давайте обстрагируемся от типа данных в данном случае)
я на LUN обычно вижу, 8,16,32,64,128,256,512К

В первую очередь посмотрите документацию СХД, скорее всего там описано какие параметры оптимальны для работы с VMWARE

Спасибо за серию статей.

Может быть, кто подскажет, куда смотреть вот в таком случае:

  1. Запущена 1 виртуалка.
  2. В ней клонезиллой копируются данные с раздела одного толстого диска на раздел другого толстого диска.
  3. В какой-то момент запускается еще 1 виртуалка, при этом скорость копирования на первой падает в несколько раз (со 120 метров в секунду до 30), в логе наблюдаются записи:
