Mô tả tổng quan
Juniper QFX5120-48Y-AFI2 là thiết bị chuyển mạch hiệu suất cao, được thiết kế làm nền tảng cho các trung tâm dữ liệu hiện đại với yêu cầu băng thông lớn và khả năng mở rộng linh hoạt. Thiết bị cung cấp các cổng truy cập 25GbE kết hợp cùng các cổng uplink 100GbE, đáp ứng nhu cầu ngày càng tăng về kết nối tốc độ cao, đồng thời hỗ trợ đầy đủ các tốc độ truy cập máy chủ phổ biến như 10GbE và 25GbE.
Với cấu hình 48 cổng 25GbE và 8 cổng 100GbE, Juniper QFX5120-48Y-AFI2 cho phép xây dựng hạ tầng mạng trung tâm dữ liệu có mật độ kết nối cao, tối ưu cho các môi trường máy chủ vật lý và ảo hóa. Thiết bị hỗ trợ luồng gió AC airflow in, phù hợp với nhiều mô hình triển khai trong tủ rack trung tâm dữ liệu.
Ngoài ra, QFX5120-48Y-AFI2 hỗ trợ đa dạng các kiến trúc chuyển mạch, bao gồm mô hình fabric trung tâm dữ liệu, triển khai Layer 3 truyền thống và kiến trúc spine-and-leaf. Nhờ đó, doanh nghiệp có thể dễ dàng mở rộng, nâng cấp và thích nghi với các yêu cầu thay đổi theo thời gian, đồng thời đảm bảo hiệu năng, độ ổn định và khả năng đầu tư lâu dài cho hạ tầng mạng.
