The GPU generation determines which numerical formats (precisions) the processor handles AI workloads fastest, its memory bandwidth and the card’s power requirements. Three generations coexist in the NVIDIA professional GPU portfolio: Ampere (e.g. RTX A6000), Ada Lovelace (e.g. RTX 6000 Ada) and Blackwell (e.g. RTX PRO 6000 Blackwell). Each successive generation supports lower compute precisions – from BF16 in Ampere to FP4 in Blackwell. The choice of generation depends on model size, compute format, number of users and hardware operating conditions. GPU types, VRAM capacity, and OEM, Retail and Bulk variants are covered in the GPUs for AI. This article…

A local LLM is a large language model running on a company computer or server rather than in a provider’s cloud. It makes sense when a company works with data it does not want to send externally, uses AI every day and has someone on the team who can maintain the environment. If none of these conditions apply, cloud services and ready-made subscription tools will be sufficient. More and more companies implementing artificial intelligence combine both approaches: they handle sensitive data and repetitive tasks locally, while using the cloud for everything else. This article explains how to calculate the costs,…

Catalyst 1200 is a managed switch for single-site networks: it provides static routing and up to 375 W of PoE power. Catalyst 1300 adds RIP dynamic routing, stacking for up to 8 devices, 2,5 Gb/s ports and up to 740 W of PoE power. Both series replace Catalyst 1000, which Cisco no longer sells and which will lose support in 2030. Below, we compare both series, translate PoE power into real-world device capacity and show how to migrate the configuration from an older switch. What are Cisco Catalyst 1200 and 1300? Catalyst 1200 and 1300 are managed Cisco switches for…

Western Digital Ultrastar is a range of HDDs designed for servers and data centres, where they operate continuously in arrays and under heavy workloads. In this guide, we compare Ultrastar models available from Senetic and explain which one is best suited to specific applications—from a single file server to storage for large data sets. What is the WD Ultrastar range? Ultrastar is an enterprise-class drive range. All current models carry the DC (Data Center) designation and share three key characteristics: The drives mainly differ in capacity, design, platter count and technologies that increase recording density. You can find the full…

Building a business network usually starts with the router supplied by the internet provider. Additional devices are added gradually: a switch, then another one, then a Wi-Fi range extender. Each purchase addresses an immediate need and makes sense on its own. Together, however, they do not form a cohesive whole. The problem emerges over time, at the least expected moment. The connection drops during a video call with a customer. The payment terminal loses network access at peak times. Cameras have been added, only to reveal there is no way to power them. This is when the question that should…

Vertiv is one of the world’s largest manufacturers of critical infrastructure for data centres, telecommunications networks and enterprise server rooms. Its scale: approximately USD 10.2 billion in revenue, around 34 000 employees, 30 manufacturing facilities and a presence in more than 130 countries. Its portfolio includes uninterruptible power supplies, power distribution, precision cooling, rack cabinets and IT management systems – in other words, virtually all server room equipment apart from the servers themselves. The company is younger than its products. Its heritage dates back to 1946, when Ralph C. Liebert founded Capitol Refrigeration Industries, while Liebert Corporation – the first…

UPS systems fall into three main categories: offline/standby, line-interactive and online double-conversion. This distinction determines whether a unit merely provides backup power or genuinely protects a server, storage system or workstation against power outages and power quality issues. An uninterruptible power supply (UPS) is often seen as little more than an “extension lead with a battery” until the first summer storm or the first power cut while a server is running. That is when the significant differences between UPS models become clear: one will safely maintain power and enable a controlled system shutdown, while another may be unable to handle…

Last updated: June 2026 Internal SSD (Solid State Drive) is a non-volatile semiconductor storage device that impacts workstation performance, infrastructure reliability, and energy efficiency of office devices. Unlike HDDs, it contains no mechanical components, which means lower failure rates and resistance to shocks during transport. If you have read our guide “Which internal SSD to choose?”, you are already familiar with terms like TBW, MTBF, IOPS, or PCIe. This article does not explain how to choose, but answers the question what to buy and why. The ranking is based on bestsellers among Senetic customers and is divided into four sections:…

The storm season is here. For businesses, this means real risks: power outages, voltage spikes, and surges that can damage IT equipment in an instant, erase unsaved data, or halt the operation of the entire organisation. In a B2B environment, every unplanned failure is not just a technical problem – it hits the bottom line. The solution is an uninterruptible power supply (UPS). That’s why we took a closer look at the offerings of APC by Schneider Electric, a global leader in uninterruptible power supplies. We’ve picked seven models from their lineup that cover businesses of every size – from…

Internal SSDs have become the foundation of IT infrastructure in companies of all sizes, as they provide fast data transfer and are virtually reliable. SSDs are also increasingly chosen over traditional HDDs. The right choice of SSD affects performance, reliability, and data security in daily operations. This guide is intended for individuals and companies planning to upgrade computers, laptops, or servers by replacing or purchasing a new internal SSD. Check what parameters internal SSDs can have and which indicate premium-class drives, and which are decent budget options. The guide also includes a comparison of popular models in 2026. What is…
