Mô tả sản phẩm
Để đơn giản hóa các hoạt động mạng, Switch Juniper EX2300-C-12T sẵn sàng hoạt động như một thiết bị vệ tinh để hỗ trợ triển khai Juniper Networks Junos Fusion Enterprise, có thể kết hợp nhiều hệ thống switch vào một nền tảng quản lý logic. Đối với các triển khai nhỏ hơn, Switch Juniper EX2300-C-12T cũng hỗ trợ công nghệ công nghệ ảo hóa của Juniper Networks, cho phép tối đa bốn thiết bị chuyển mạch được kết nối để được quản lý như một thiết bị logic duy nhất, cung cấp giải pháp có thể mở rộng, và backup dự phòng khi có sự cố xảy ra.
