We use a S5850-48T4Q 10GBase-T switch to replace S5850-48S6Q 10G SFP+ switch as top of rack (ToR) switch. The interconnections between the S5850-48T4Q switch and the server is achieved via 10G Cat6a Ethernet cables, saving the cost on purchasing SFP+ transceivers. These ToR switches are then uplinked to S5850-48S6Q switches at the aggregation layer via cost-efficient 40G QSFP+ DACs.
The S1600-48T4S PoE switches and the stackable S3900-48T4S switches are all aggregated to the S5850-48S6Q switch with low-cost 10G SFP+ DACs. The 10G DACs are ideal for connection within racks and between adjacent racks.
4×S3900-48T4S switches are stacked as a single entity. The switch stacking can be achieved through 10G SR transceivers or 10G SFP+ DACs. We choose 10G SFP+ DACs to cut down the overall costs. Generally, up to 6 S3900-48T4S switches can be stacked together. This video illustrates the steps for stacking switches.
These two buildings are located within 500ft, so 2 lanes of high-performance, reliable 10G OM3 bend insensitive fibres (BIFs) are placed to connect the aggregation switches of each building.
