Низкая скорость гибридного Raid 10 (4hhh+4ssd) Adaptec 6805

Сообщение Ract » 17 окт 2012, 11:28

Имеем:
1. Supermicro 6026t-urf (2x XEON 5507)
2. Adaptec 6805 raid10 (4ssd Vertex3 + 4 hdd)
3. ESXI 5.0 (виртуалка win2003 - режим контроллера vmwareparavirtual)

Вчера создал хранилище со страйпом 1024 (мыслил т.к. vmfs 1 mb). Запустил тест HDTune. Увидил безумно рваный график от 200 до 2000 mb/s средняя была 1500 . Померил IOPS в случ. тесте 512б и 4 кб были больше 15 000.

В ночь решил переделать рейд10 в страйп 256 - с утра померил и увидил следущее:

Думаю ESXI тут не причем, все дело в правильном страйпе?
