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 ...

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 ...

This model shows that even a small 2-disk desktop NAS can pleasantly surprise with storage capabilities: up to 4 NVME SSDs and up to 16 hard drives when using cards and expansion shelves. The ability to configure layer-by-layer storage and run applications in containers in a compartment with a 2.5-gigabit network makes it an excellent choice for a modern office with remote access and Wi-Fi 6. I already described the concept of a modern office in which all employees work remotely and only ...

The most difficult thing is not even to pick up packages to replace Synology services with free ones, but to support their work, promptly responding to glitches and updates. This is not an easy, but doable task that can be completed in a few weeks. Installing applications, configuring services Having planned the storage, I proceed to installing the software. Docker is already installed, and now I will install MergerFS and SnapRAID file system support for the archived data array. For example ...

You are very lucky if you used the NAS's of this company only for storing files: you will easily find a replacement for yourself. It's much worse if your business is actively tied to DSM services, including those related to virtualization, video surveillance, backups and fault tolerance. After the events of February 2022, Synology was one of the first to file for divorce and leave the Russian market. This means that any other market is not immune from the fact that the company does not fall ...

The cryptocurrency market has collapsed, and let's leave the romance and childhood dreams and admit to ourselves: cryptocurrencies will not be able to break the financial system with banks. We already have an example of excellent free Linux operating systems, which were also predicted for the great future, but failed. TL;DR :   the absence of a leader, a strategy, a clear sales model and an administrative resource creates chaos on the site of open projects, from which nothing worthwhile can ...

A very unusual NAS, which the manufacturer himself considers to be Smart Edge switches. It has a built-in PoE switch for 16 ports, as well as 2.5-Gigabit Upstream interfaces and a software architecture with isolated network spaces for video surveillance. Usually, the infrastructure of video surveillance systems in buildings is hidden in telecommunication cabinets, installed in isolated rooms, away from prying eyes and ears. However, not every company can afford a dedicated space for NVR ...

Now customers have the opportunity to use ZFS in entry-level storage: now you can combine deduplication and SAN connection via FC, configure caching of Cloud storage on a local disk, and synchronize backups between cloud services. Plus, you can mine cryptocurrency directly on the NAS. In the 2020s, QNAP could no longer avoid using a file system with Copy On Write support: yes, three years ago they had a powerful 2-controller machine based on the FreeBSD kernel in their arsenal, but the lack ...

In small companies, NAS can significantly reduce infrastructure costs. Those who decommissioned servers yesterday by moving resources to the NAS are canceling their subscriptions to the software that QNAP performs out of the box today. And now the time has come when QNAP swooped down on the sacred: the reservation of virtual machines. In 2019, the world market for backup and data recovery software, according to estimates by Allied Market Research, amounted to $ 9.3 billion. An article of ...

QNAP has got very interesting monstrous NAS-s for working with large amounts of data. The storage system under consideration today with a head unit for 24 3.5-inch hard drives makes it possible to pack 384 TB of data into one system and do without expansion shelves at all, which may be quite enough for the needs of a small enterprise. QNAP has got very interesting monstrous NAS-s for working with large amounts of data. The model under review with the long name TS-2483XU-RP is a data storage ...
