Сетевая карта LR-LINK LREC9712HT-BP

Основные технические характеристики LR-LINK LREC9712HT-BP:

• Сетевая карта LR-LINK LREC9712HT-BP
• Порты: Два порта RJ45
• Скорость: 1 Гб/с
• Чипсет: Intel i350AM2
• Шина: PCI-E x4
• Форм-фактор: Low profile (LP)
• Bypass Server Adapter, bypass, dual port bypass, copper bypass

Описание:

• Bypass сетевая карта LR-LINK LREC9712HT-BP базируется на чипе Intel i350.
• Поддерживает виртуализацию Intel I350 PCI-SIG Single-Root I / O и совместное использование спецификации (SR-IOV).
• Сетевой адаптер LREC9712HT-BP работает в режимах: Normal, Disconnect и Bypass.
• В режиме Normal, порты сетевого контроллера являются независимыми интерфейсами.
• В режиме Bypass, все пакеты, принятые от одного порта передаются на соседний порт и наоборот.
• Эта функция позволяет обойти отказ системы.
• В Disconnect режиме, адаптер имитирует отсоединения кабеля от коммутатора/ маршрутизатора.
