Stacking of Zyxel XGS2220 series switches: testing features

Switch stacking technology allows you to combine several physical switches into one virtual switch, combining their switching matrices and simplifying port management from a single stack web interface. One of the most popular functions of the stack is to combine ports from different switches into common lagging groups to get a fault-tolerant network that can withstand the breakdown of N-(N-1) switches. I want to draw attention to the fact that modern Zyxel combines support the connection of up ...

What is Edge Computing and why edge computing is an escape from the cloud

Think of devices that monitor production equipment in a factory, or a video camera that sends real-time recording from a remote office. As long as there is only one device, it is quite easy to transmit them over the network, but with the growth of their number, there are already problems with delays. We recently wrote about how the oil and gas industry uses IoT to place hundreds and thousands of sensors on its facilities. With so much input data transmitted by all these multiple IoT devices, ...

Secrets of professionals: how to scale datacenters of cloud providers

Have you always wondered how Data center operators choose and configure their equipment? Why, for example, do they install server "A" instead of "B", what do they rely on - the speed of the VM or the potential number of them in the rack, and how do they design computing power? You have probably seen many times epic photos from data centers, in which drains clogged with servers go over the horizon, powerful generators and air conditioning systems are installed. Many people ...
