В первом квартале этого года наша компания ADVANSERV стала первым авторизованным представителем компании Fusion-io в России.
Вместе с красивым сертификатом и официальным статусом мы получили карту Fusion-io ioDrive2, как говорится «на пощупать» нашим техническим специалистам, и мы в свою очередь уже активно даём его для проведения тестов нашим клиентам.
Нашим тестовым экземпляром была плата объёмом 1,2Tb на MLC памяти. Да, плата не из самых новых-передовых, но вполне, пожалуй, достойна детального разбора. Заявленные производителем характеристики выглядят следующим образом:
В общем-то — ничего особенного для современных PCI-E SSD мы тут не видим, но наша задача не просто посмотреть на цифры, предлагаемые производителем, но и проверить — насколько они отличаются от реальных показателей в работе, ведь и задачи, и методы тестирования у всех крайне сильно отличаются. Мы немного поиздевались над платой, полностью её разобрав, дабы заглянуть и посмотреть — что же там внутри.
Вскрытие показало, что он построен с применением платы FPGA следующего поколения для управления флешем — Virtex-6 производства Xilinx.
А вот реализация модулей памяти на плате приятно удивила (правда пока сложно сказать практическое применение данного решения), они не просто распаяны на плате, они вставляются в специальные разъём несколькими модулями.
Но сами модули выглядят следующим образом (а снизу соответственно две продольные ножки, которыми эти модули вставляются в слоты).
К сожалению, у нас не нашлось второй такой платы, чтобы проверить взаимозаменяемость этих модулей, возможно, в случае выхода из строя какого-то из наборов памяти, это облегчит гарантийный ремонт платы, так как не придётся заменять её целиком. Тут, к сожалению, как и в обзоре Fusion-io ioDrive Duo нас постигло разочарование — несмотря на использование нескольких отдельных модулей, ни о каком аппаратном RAID`е речи не идёт. Возможно это задел на будущее, так как для работы на таких скоростях требуются достаточно большие вычислительные мощности и как следствие — охлаждение, но хочется всё-таки надеяться, что когда-нибудь мы сможем оценить прелести аппаратного RAID при использовании PCI-E SSD устройств.
Ну что же, давайте перейдём непосредственно к тестам. Прежде чем говорить о железной составляющей нашей тестовой машины, хотелось бы уточнить один момент, который не был озвучен в обзоре Fusion-io ioDrive Duo — требование к объёму оперативной памяти. По словам производителя (при использовании блоков 4096b) на каждые 100Gb объёма накопителя требуется 530MB оперативной памяти. Соответственно, для того что бы накопитель на 1,2Tb работал «правильно», требуется минимум ~6,5GB оперативной памяти.
Конфигурация тестового стенда:
Платформа — <a href=«www.advanserv.ru/products/servery/prodution/hp-proliant-dl380-g7
Процессор — Xeon E5606
Память — 8 Гб
Жесткие диски — 2xSAS 146Гб 10k
После нескольких наших статей по накопителям в прошлом году и по отзывам к ним мы немного изменили набор проводимых нами тестов и теперь он выглядит следующим образом:
ATTO Disk Benchmark
Мы проводили тестирование с параметрами:
Total Length = 256 Mb
Queue Depth = 2-10
AS SSD Benchmark IOPS
AS SSD Benchmark MB/S
AS SSD Copy-Benchmark
Уже можно сравнить полученные результаты с предшественником ioDrive Duo и увидеть практически двукратное увеличение производительности. Продолжим с синтетическими тестами:
CrystalDiskMark
Здесь мы видим 50% прирост производительности при последовательном чтении/записи и при работе с большими блоками в 512k.
Iometr
Для тестирования был выбран, уже опробованный нами, набор паттернов:
В качестве результатов были выбраны максимальные, полученные значения при тестировании.
Fio
Тест fio в наших обзорах появился после публикации на habrahabr`е статьи „Как правильно мерить производительность диска“, которая стала неким эталоном тестирования различных СХД.
Для тех кто хочет увидеть все цифры своими глазами, предлагаю лог тестов:
И последний, лишь в этом тестировании, но не по значимости
SQLIO Random Reads Test iops
SQLIO Random Reads Test mbps
SQLIO Random Writes Test iops
SQLIO Random Writes Test mbps
SQLIO Sequential Reads Test iops
SQLIO Sequential Reads Test mbps
SQLIO Sequential Writes Test iops
SQLIO Sequential Writes Test mbps
Опять-таки для любителей информации в текстовом варианте, предлагаю логи тестов:
Теперь немного слов о ПО идущем в комплекте. Тут по-прежнему есть 2 варианта: Dell IO Manager или HP IO Accelerator Management Server. Я уже по-привычке пользуюсь web-интерфейсом от HP, он не притерпел никаких изменений по сравнению с версией идущей с ioDrive Duo. Настройка, перепрошивка, подключение дисков, информация об ошибках и т.д. прекрасно представлены, с утилитой удобно и просто работать.
Отдельно хотелось бы коснуться темы перепрошивки — в тесте ioDrive Duo мы лично уже убедились, что от прошивки зависит очень многое, в том числе и скоростные характеристики устройства, но тут есть и обратная сторона. При обновлении драйверов для устройства, необходимо каждый раз возвращать старую прошивку, идущую в комплекте с данным драйвером. Процесс этот конечно несложный, но времязатратный (для моделей большого объёма), и, что самое главное, после перепрошивки карты форматируется. Этот не совсем очевидный момент может сыграть большую роль при выборе устройства.
От себя хочу добавить, что при установке карты под linux, мне пришлось достаточно освновательно поиграться с драйверами и прошивками, прежде чем удалось заставить устройство работать. И, хоть процесс установки и настройки не такой уж и сложный, повторюсь, может занять определённое кол-во времени.
Существует возможность работы карты в двух вариантах: через стандартный менеджер устройств linux — udev, либо, запуская драйвер карты, как сервис.
На этом хочется закончить сегодняшнее тестирование. Я считаю, что обновлённая линейка карт ioDrive вполне удачна, она имеет заметное преимущество перед картами предыдущего поколения, компания постоянно работает над прошивками и драйверами к своим устройствам, выпускает новые модели (за обзором которых мы конечно охотимся очень активно, но карты приезжают к нам с некоторым запозданием) и работает над развитием технологий. Многие компании уже обратили внимание и на саму технологию PCI-E SSD и на решения от компании Fusion-io и активно внедряют их в своей инфраструктуре.
Напоминаю, что вы можете получить в demo данно карту, или мы предоставим удалённый сервер с установленной платой, сконфигурированный для ваших целей, и вы сможете провести тестирование удалённо. Для приобретения Fusion-io или запроса demo просьба обращаться к руководителю направления Алексею Котову.

Теперь немного слов о ПО идущем в комплекте. Тут по-прежнему есть 2 варианта: Dell IO Manager или HP IO Accelerator Management Server. Я уже по-привычке пользуюсь web-интерфейсом от HP, он не притерпел никаких изменений по сравнению с версией идущей с ioDrive Duo. Настройка, перепрошивка, подключение дисков, информация об ошибках и т.д. прекрасно представлены, с утилитой удобно и просто работать.
Отдельно хотелось бы коснуться темы перепрошивки — в тесте ioDrive Duo мы лично уже убедились, что от прошивки зависит очень многое, в том числе и скоростные характеристики устройства, но тут есть и обратная сторона. При обновлении драйверов для устройства, необходимо каждый раз возвращать старую прошивку, идущую в комплекте с данным драйвером. Процесс этот конечно несложный, но времязатратный (для моделей большого объёма), и, что самое главное, после перепрошивки карты форматируется. Этот не совсем очевидный момент может сыграть большую роль при выборе устройства.
От себя хочу добавить, что при установке карты под linux, мне пришлось достаточно освновательно поиграться с драйверами и прошивками, прежде чем удалось заставить устройство работать. И, хоть процесс установки и настройки не такой уж и сложный, повторюсь, может занять определённое кол-во времени.
Существует возможность работы карты в двух вариантах: через стандартный менеджер устройств linux — udev, либо, запуская драйвер карты, как сервис.
На этом хочется закончить сегодняшнее тестирование. Я считаю, что обновлённая линейка карт ioDrive вполне удачна, она имеет заметное преимущество перед картами предыдущего поколения, компания постоянно работает над прошивками и драйверами к своим устройствам, выпускает новые модели (за обзором которых мы конечно охотимся очень активно, но карты приезжают к нам с некоторым запозданием) и работает над развитием технологий. Многие компании уже обратили внимание и на саму технологию PCI-E SSD и на решения от компании Fusion-io и активно внедряют их в своей инфраструктуре.
Напоминаю, что вы можете получить в demo данно карту, или мы предоставим удалённый сервер с установленной платой, сконфигурированный для ваших целей, и вы сможете провести тестирование удалённо. Для приобретения Fusion-io или запроса demo просьба обращаться к руководителю направления Алексею Котову.
