Как мы морских карасей ловили, или обзор Huawei OceanStor Dorado2100 G2



    В конце 2012 года, компания Huawei представила второе поколение системы хранения данных OceanStor Dorado2100 G2. Нам стало интересно сравнить её с недавно побывавшей у нас на тестировании Flash СХД IBM FlashSystem 820. Но сначала немного подробнее о Dorado.


    Архитектура Dorado2100 G2 целиком построена на твердотельных накопителях SSD и использует усовершенствованную технологию управления кэш-памятью и алгоритмы планирования операций ввода-вывода. Высокая надежность системы обеспечивается за счет резервирования компонентов: источники питания, вентиляторы, контроллеры, интерфейсные модули, SSD и BBU продублированы и позволяют избежать возникновения единичных отказов, а используемые методы балансировки степени износа, восстановление поврежденных блоков и технологии scrubbing позволяют значительно продлить срок службы носителя, обеспечивая среднее время безотказной работы (MTBF) свыше 1200000 часов. Мощность устройства 580Вт позволяет экономить до 90% энергозатрат по сравнению с традиционными дисковыми массивами.

    ПО дублирования каналов (Multipathing) UltraPath


    В качестве сфер, где может быть полезна Dorado2100 G2, называются работа с базами данных, ERP-системы и «облачные» сервисы.

    Теперь я хотел бы уделить несколько слов средствам управления данной СХД. Основным инструментом настройки является OceanStor ISM, написанный на Java и, соответственно, кросплатформенный. Да, это не привычный веб-интерфейс, это не так удобно, но тем не менее вполне работоспособно. Собственно ничего необычного там нет, всё достаточно стандартно — настройка контроллеров, дисков, Lun`ов и т.д. Всё, что необходимо для подготовки к работе СХД.



    Ну и естественно там имеются простые средства для мониторинга нагрузки системы. Вторым же средством управления, является консоль UltraPath, которая позволяет немного «тюнинговать» работу системы. Подробнее о возможностях UltraPath можно прочитать на сайте Huawei.

    Вспоминая наша недавнее тестирование Huawei Tecal ES3000 мы достаточно многого ожидали от китайского производителя, что же получилось на практике — покажут наши тесты, к которым мы и переходим.

    Конфигурация тестового стенда:
    • Платформа — IBM X3650 M4
    • Процессор — Xeon E2603
    • Память — 8 Гб
    • Жесткие диски — 3xSAS 146Гб 10k


    Тестирование СХД мы проводили при помощи нашего стандартного набора тестовых пакетов, которые мы уже неоднократно использовали в наших статьях.

    ATTO Disk Benchmark
    Мы проводили тестирование с параметрами:
    • Total Length = 256 Mb
    • Queue Depth = 2-10












    AS SSD Benchmark







    CrystalDiskMark



    Iometer
    Для тестирования был выбран уже опробованный нами набор паттернов:
    • Database
    • File Server
    • Workstation
    • Webserver


    В качестве результатов были выбраны максимальные полученные значения при тестировании.



    Fio
    Здесь мы проводили 2 тестирования: первое тестирование было с использованием Multipath, а второе при помощи UltraPath, которую предлагает использовать сама Huawei. При тестировании в Windows мы привели результат только с использование UltraPath, ввиду того, что результаты тестов при использовании Multipath отличались не более чем статистическая погрешность при тестах.

    Multipath








    UltraPath








    Как вы можете заметить, на графике нет результатов тестов при iodepth=128, по неизвестной причине, при использовании UltraPath, сервер просто зависал при проходе этого теста.

    Для тех, кто хочет увидеть все цифры своими глазами, предлагаю лог тестов:

    Что ж, чуда не произошло, хотя мы этого и ждали от данного устройства. Если сравнивать с тем же IBM FlashSystem 820 который у нас был (мне привычнее сравнить с тем, что уже побывало у нас в руках) Dorado2100 G2 проигрывает по многим показателям почти в 2 раза. Если учитывать цену Dorado2100 G2 покупка становится не выгодной (если вы хотите СХД объёмом 10-20Тб), однако, если вам нужно небольшое хранилище объёмом 2,5Тб для малого бизнеса — к покупке Huawei OceanStor Dorado2100 G2 стоит присмотреться внимательнее.

    Что касается цены — рекомендованная стоимость модели 2,5Тб составляет $75000. Оформив заказ в течении недели с момента этой публикации и указав ключевое слово — «Компилятор» и получите скидку до 20% (размер скидки будет зависит от общей стоимости вашего заказа).

    Хочу напомнить, что Вы можете взять данную СХД у нас в Demo на тестирование, или же мы можем предоставить удаленный сервер, сконфигурированный под ваши задачи и с подключённой к нему Huawei OceanStor Dorado2100 G2. По всем вопросам по СХД Huawei обращайтесь к нашему руководителю направления — Воронову Ивану.

      Да, что-то IOPSов крайне мало. Так что чудо совсем не произошло.
      Даже мой самодельный массив из 10k HDD + SSD кэш после прогрева кеша выдает 5-7к iops на случайном чтении.
      А тут чисто флеш… не впечатляет.

        К сожалению, да, девайс несколько разочаровал своими способностями.

          Может быть ситуация изменится с выходом обновлений ПО?

            Всё возможно, но боюсь прежде чем выйдет новая прошивка, железка от нас уже уедет.

        Большая латенси для SSD что-то.

        GPL озвучьте на несколько моделей в полной комплектации.

          У вас получились очень странные результаты. Массив может выдавать гораздо больше. Вы его не загрузили полностью:
          image
          Результат — полный рандом, 100 потоков fio, суммированние по всем потокам.
          Система AIX, qdepth=4, но это важно только для для одного потока (как у вас). Когда потоков больше 1, то глубину очереди надо смотреть и настраивать совсем в другом месте.

            Тестирование в fio производилось по методике товарища amarao.
              +1
              я тоже пользовался методикой которая согласуется с геноссе амарао. Однако у меня получилось загрузить суровее. :) Дело в том. что у этого стораджа глубина очереди портов, насколько я помню 8*256=2048 команды. Поэтому даже qdepth=128 это ни о чем. Но уперлись вы в другое (как я подозреваю): fio не смог нагенерировать столько трафика, или из-за того, что уперся в процессор (потому как висит на одном ядре), или просто из внутренней архитектуры (блокировки). Если расспараллелить, то получится веселее :) Суммировать и рисовать красивые картинки, правда, сложнее.

                Предлогаете запускать несколько процессов fio? А как потом результаты считать — просто сложением полученных результатов?
                  0
                  Предлагаю поэкспериментировать. )
                  Кстати, вот такие результаты для FS820:

                  а вот такие для es3000 (4k)

                  А то у вас результаты мощнейших железок — просто обнять и плакать :)
                    0
                    Ну вообще раньше у нас fio справлялся с задачей и железки выдавали на порядок больше IOPS`ов в тех же тестах по той же методике. Хотя у меня небольшой опыт работы с внешними хранилками на FC, возможно тут есть своими особенности?
                      0
                      15к это на порядок? :) у меня на той же железке — 300к
                        0
                        ммм… почему 15k? Я смотрел замеры fio, тут 41k/24k против 185k/163k.

                          Пардон, не на тот график посмотрел. Но 185 это тоже не 300 :)

                            Ну не 300, но и не 40. А сервер был тот же самый.

                              Я, кажется, запутался: у меня получилось на 4Kб чтение — 322к на ES3000, 204к на 2100G2 (raid10) и 408к на FS820.
                              Сколько у вас?
                                0
                                если брать 4Кб, то
                                ES3000 — 22757
                                2100G2 — 3400
                                FS820 — 22396

                                в любом случа результат 2100G2 на порядок ниже остальных, т.е. дело не в fio.
