10G Redundant Connection for Storage Cabinets and Servers

  • Telecommunication
  • United States


A reliable network solution could save much time and energy for users. Trapped in network construction, one of our customers turned to FS for help, hoping to receive a 10G redundant connection solution for storage cabinets and servers.


The customer wants to get redundant connections to four storage cabinets and three servers over 10GB SFP+ link. And 250 1GB ports are needed for user network with 10GB link to the server trunk and cabinets. While there is only one firewall with 1 GB copper RJ45 connections. How to balance the requirements becomes a tough thing.


According to customers’ needs, FS provides a network connection solution. The overall design of the solution adopts the MLAG function, making fully redundant links at the core and access layers, to avoid network paralysis caused by a single point of failure from the core and the access switches.


    The Core Layer: Two FS S5850-32S2Q switches are connected by 40G link trunk. Each of the S5850-32S2Q connects the firewall with a 1G copper module and network cable, realizing the MLAG connection for link redundancy.


    The Access Layer: FS S3900-48T4S switches are used as access switches to link terminal devices of the user area. Each of them establishes a 10G uplink connection with S5850-32S2Q using MLAG. In addition, servers and cabins set up 10G connections with the two S5850-32S2Q over MLAG as well. All the MLAG design achieves high reliability and network redundancy for the whole network.

Note: The 10G port speed of S5850-32S2Q needs to be set to 1G for firewall connection.

S5850-32S2Q, 32-Port Ethernet L3 Fully Managed Plus Switch, 32 x 10Gb SFP+, with 2 x 40Gb QSFP+

US$ 2,659.00

S3900-48T4S, 48-Port Gigabit Ethernet L2+ Fully Managed Switch, 48 x Gigabit RJ45, with 4 x 10Gb SFP+ Uplinks, Stackable Switch, Broadcom Chip

US$ 529.00
