Функционал RoCEv2 в коммутаторах QTECH уровня ЦОД серий QSW-6900 и QSW-6700
24 августа 2026
Современные центры обработки данных предъявляют все более высокие требования к сетевой инфраструктуре, требуя оптимизации процессов передачи данных и повышения эффективности сети в целом. Одной из ключевых технологий, позволяющих достичь этих целей, является Remote Direct Memory Access (RDMA) — технология удаленного прямого доступа к памяти.
На базе стандарта Ethernet самым распространенным и оптимальным решением RDMA является стек протоколов RoCE (RDMA over Converged Ethernet, доступ к памяти через «конвергентный Ethernet»), в частности — его 2-я версия RoCE v2, дающая значительные преимущества в части производительности и гибкости сетей. RoCE v2 позволяет напрямую обращаться по сети к системной памяти, минимизируя участие центрального процессора в сетевой коммуникации и уменьшая задержки.
В данной статье приводим результаты тестирования и примеры настройки RoCE v2 для коммутаторов QTECH для сетей ЦОД серий QSW-6700 и QSW-6900. Обе серии коммутаторов используются в сетевых фабриках — как в качестве Spine, так и в качестве Leaf, поддерживают весь требуемый функционал и соответствуют актуальным стандартам коммутаторов, используемых в сетях ЦОД.
Управляемый коммутатор, 8 портов 100GbE QSFP28, 48 портов 25GbE SFP28, до 122K MAC адресов, 1 порт USB 2.0, консольный порт, порт управления MGMT, 2 сменных БП, 100-240В AC, размеры ШхГхВ (440x470x44 мм)
Управляемый коммутатор, 32 порта 100GbE QSFP28, до 122K MAC адресов, 1 порт USB 2.0, консольный порт, порт управления MGMT, 2 сменных БП, 100-240В AC, размеры ШхГхВ (440x470x44 мм)
Управляемый стекируемый коммутатор уровня L3, 8 портов 100GbE QSFP28, 48 портов 25GbE SFP28, до 96K (до 160K в режиме Bridge), 1 порт USB 2.0, консольный порт, порт управления MGMT, 2 сменных БП (не входят в комплект), 100-240В AC, размеры ШхГхВ (442x387x44 мм)
Управляемый стекируемый коммутатор уровня L3, 8 портов 100GbE QSFP28, 48 портов 10GbE SFP+, до 96K (до 160K в режиме Bridge), 1 порт USB 2.0, консольный порт, порт управления MGMT, 2 сменных БП (не входят в комплект), 100-240В AC, размеры ШхГхВ (442x387x44 мм)
Управляемый стекируемый коммутатор уровня L3, 32 порта 100GbE QSFP28, до 96K (до 160K в режиме Bridge), 1 порт USB 2.0, консольный порт, порт управления MGMT, 2 сменных БП (не входят в комплект), 100-240В AC, размеры ШхГхВ (440x560x43,5 мм)
