CRS504-4XQ-IN: affordable, compact, and energy-efficient 100 Gigabit switch. Multiple power options, dual hot-swap power supplies.

There are four 100 Gigabit QSFP28 ports. Use them to connect other 100 Gigabit devices, or grab a breakout cable to connect multiple 25 Gigabit devices: each port is linked to four 25 Gigabit lines, allowing you to connect 16 x 25 Gigabit devices. In fact, this way you can mix and match all kinds of connections: 100 Gigabit on one port, 40 Gigabit on the other, 4x25 Gigabit on the third, and maybe even some 10G or 1G cables on the fourth. Of course, there's also an Ethernet port for management.

We've been using this switch for a while now in the Genomics Data Network project. A high-capacity data network for our local scientists working on innovative cancer treatments. Genome data can take up a lot of space, so you need exceptionally fast connections. Moreover, with these devices, Latvia became the first Baltic country to establish a 100 Gigabit connection to the pan-European research network.
