Can switch ports be aggregated to increase throughput?

Question

Computer networks

Welcome all.
It is necessary to connect two geographically dispersed nodes with optical fiber and provide a network bandwidth of 1.8 Gb / s.
Is it possible to install an HP 1820-48G copper-optical switch on each node and connect them with two SFP ports? Will the data transfer rate between the two switches increase to 2 Gbps?
Thank you!

Answer 1

no, the channel will become wider, but the maximum transfer rate between two nodes will still be 1 Gbps.
the profit from aggregation is for a large number of clients/connections.
look towards 10G ports and modules. If there are few rules on trunks, then you can put simple ones like dlink dgs-1510.

Answer 2

To get this speed in all cases, I would use 10GB ports on each side. If this is not possible, then you can try Etherchannel (bonding), your switch can do this, under certain conditions you can get 2GB.
Here is the manual , look for LACP and balancing.

Answer 3

Looking at how to approach this issue.
To simplify, it works like this: before, 1 file was transferred over one port at a speed of 1GB, and now, using aggregation, it will be possible to transfer 2 files simultaneously over two ports at the same speed of 1GB.

Answer 4

This is called link aggregation. If the equipment allows such an opportunity, then it is possible.

Answer 5

LACP to the rescue, set up everything works.
