– Клас дата-центру – DataHouse.ua Tier III/IV –
Сучасний дата-центр рівня Tier III / Tier IV гарантує надійність, безперервність бізнес-процесів і повну резервованість послуг.
Через численні запити ми хочемо пояснити тему класифікації TIER дата-центрів та відповісти на поширені запитання. Нижче – зрозумілі та чіткі відповіді у форматі Q&A.
A: Класифікація TIER означає, що дата-центр відповідає певним технічним і фізичним вимогам за встановленим стандартом. На відміну від сертифікації ISO 27001:2013, яка охоплює організаційні та процедурні аспекти, класи TIER стосуються виключно технічної інфраструктури та її фізичної надійності.
Q: За якими стандартами визначається рівень TIER?
A: Основним стандартом є американський ANSI/TIA-942. На його основі інші організації розробили власні системи, наприклад, Uptime Institute зі США. У Німеччині діє окрема система рейтингів Star, що містить 5 рівнів (на відміну від 4 у ANSI/TIA).
Q: Яка система класифікації вважається дійсною?
A: Усі системи вважаються дійсними, якщо організація чітко вказує, до якої саме системи вона посилається. Наприклад, відповідність Tier 3 за ANSI/TIA-942 не є рівнозначною Tier 3 від Uptime Institute чи 3 зіркам у німецькій системі. DataHouse.ua використовує стандарт ANSI/TIA-942 і надає докладні результати відповідності у вигляді структурованих таблиць за категоріями стандарту.
Q: Яка система класифікації вважається дійсною?
A: DataHouse.net meets all the requirements of Tier 3 according to the ANSI/TIA-942 standard, and parts of the newest facility meet Tier 4 standards.
Q: Чи існують офіційні сертифікати TIER для дата-центрів?
A: Так, Uptime Institute видає сертифікати на основі власного стандарту TIER. Сертифікація виконується поетапно, тобто повна відповідність вимагає окремих аудитів і сертифікатів для кожного розділу.
У Польщі, через високу вартість, наразі було видано лише дві часткові сертифікації Uptime Institute — для об’єктів у Катовіце та Торуні.
Також існує німецька система "Star", але вона застосовується лише в межах Німеччини.
Q: Чи реально досягти рівня Tier 4 у Польщі?
A: За стандартом ANSI/TIA-942 — так, це можливо. Але за стандартом Uptime Institute виконання всіх вимог (особливо щодо енергопостачання) є дуже складним.
Однією з головних перешкод є вимога подвійного електроживлення з двох повністю незалежних енергосистем.
Схожі вимоги є і в німецькій системі 4 зірок, з додатковим акцентом на використання відновлюваних джерел енергії.
