Huawei CE7855-32Q-EI Switch is a new generation of high-performance, high-density, low-latency 40GE Ethernet switches for data centers and high-end campuses.
Huawei CE7855-32Q-EI Switch Product Overview
Huawei CE7855-32Q-EI Switch provides high-density 40GE QSFP+ ports, and supports rich data center features and high-performance stacking. This helps enterprises and operators build data center network platforms for the cloud computing era. Huawei CE7855-32Q-EI is located at the core or aggregation of the data center and can also be used for the core or aggregation of the campus network. CloudEngine 7800 series support multiple data center features: Uz prioritāti balstīta plūsmas kontrole (PFC), Uzlabota pārraides izvēle (ETS) un Data Center Bridgeging eXchange (DCBX). Šīs funkcijas nodrošina zemu latentumu un nulles pakešu zudumu FC krātuvei un ātrdarbīgiem skaitļošanas pakalpojumiem.
Users or third-party developers can use open APIs to develop and deploy specialized network management policies to implement extension of fast service functions, automatic deployment, and intelligent management. The OPS also implements automatic operation and maintenance, and reduces management costs
Turklāt, Huawei CloudEngine 7855-32Q-EI Switch can work with the CloudEngine 16800/CloudEngine 12800/CloudEngine 6800/CloudEngine 5800, which is a flexible, simple, open, and secure cloud data center network.
