The Zyxel CX4800-56F is a high-density L3 aggregation optical switch in which the company pioneered the use of 100G ports: 8 QSFP28 100GbE uplinks complement 48 SFP+/SFP28 slots with 10/25gbe support, forming a single 56-port stack for traffic aggregation in campus and data centers factories. With a pass-through switching matrix of up to 4 Tbit/s and forwarding speeds of up to 2 billion packets per second, this switch confidently closes scenarios of highly loaded highways, where not only ...

We have a rather interesting class of L3 switches in front of us: multi-gigabit PoE models with a relatively small number of ports, an average PoE budget by modern standards, but 10-gigabit uplinks. They are interesting because the manufacturer has placed 2.5G PoE + 10G in a compact 9-inch rack housing with a silent fan, and such a switch can be installed at home, in a 1-room office, under a false ceiling or in narrow telecommunication cabinets. We have a rather interesting class of L3 ...

We will take two switches: the Taiwanese brand Zyxel and the Chinese counterpart from a little-known manufacturer and look at the design differences and what they affect in order to answer the question - does it make sense to overpay for design features? It's no secret that almost all modern electronics are manufactured in China, even if they are developed in the USA, Europe, Japan or Taiwan – the Chinese have not only learned how to do things efficiently, but have also grown such IT giants ...

This is a 28-port switch, in which 4 ports are gigabit optics for Uplink, and the remaining 24 ports are 1-gigabit RJ45 PoE with a total power budget of 370 watts, and each of these ports can work both in 802.3af mode (up to 15.4 watts) and and in the mode 802.at (up to 30 watts). When integrating into the project, some features of this switch should be taken into account. Level 3 switches with PoE support are usually used to build enterprise Wi-Fi networks and video surveillance systems. And ...

RAID controllers have not left and are not going to, on the contrary, hardware controllers for NVME and PCI Express drives (including M2 format drives) are entering the market. The abundance of drives and software features of RAID/HBA make you approach this choice as responsibly as possible, otherwise you may lose data. RAID controllers have not left and are not going to, on the contrary, hardware controllers for NVME and PCI Express drives (including M2 format drives) are entering the ...

Zyxel reasoned this way: if the L3 functionality is already determined only by the firmware, 99% choose an access switch for the sake of port density, PoE, VLAN, Multicast, and less often for static routing, then here's the base model XMG1930, which is generally L2, but slightly L3. And if your network requires advanced L3 functions, then all this is also there, just buy the appropriate license and get the core-level functionality. You can do this at any time, even when buying a device, even ...

Server fans play a key role in maintaining the temperature at an optimal level. They operate at high speeds to ensure sufficient airflow within the server system, thereby cooling it. Most server fans are designed to operate at different speeds, which significantly enhances their efficiency. This means that when the server system is under load, the server fans operate at higher speeds to increase cooling, and when the load is light, the speed decreases. The main function of server fans is to ...

Zyxel has a series of simple unmanaged switches for 2.5-Gigabit networks, with 5 and 8 ports. Both have a non-blocking switching matrix for full bandwidth: 25 and 40 Gbit/s, respectively, that is, they can be used in the most loaded networks. We will review and test the 8-port model. That's how you live and don't think that the 1GBaseT standard has been exchanged for the third decade. Introduced back in 1999, it managed to acquire a lot of faster options, but it is still not going to give up ...

Hyperconverged systems are rapidly gaining popularity and are already becoming the standard for building virtualization platforms in the corporate environment. Lenovo has released a special series of servers for installing and running VMware vSAN with tools for simplified administration and deployment at the customer's facility. The ideology of hyperconvergent solutions using VMware technologies has its advantages: this is a relatively low cost at the start, and the ability to scale almost ...

An interesting solution for home laboratories, small test rooms or maintenance-free points where 1-2-3 pieces of equipment are placed, and every square centimeter is worth its weight in gold I often came up with the idea: why not place servers vertically, because if you do not have a special server rack, but have a 1U-4U machine, and even a full length of 655 mm, then this bandura will take up the entire room, the entire table or rack. No, I'm not saying that server cabinets are outdated and ...
